iPhone vs Lumia 928

Nokia Lumia 928 lags far behind the iPhone 5 in new screen latency test

A new test developed shows Apple far ahead of Android and Windows Phone for reduced display latency

When it comes to smartphones, screen response time is one of those key features that helps ensure a great user experience. Some of you may recall the use of resistive touch panels on smartphones years ago and how slow those were to respond to touch. Capacitive displays are certainly much quicker, and it’s the reason why touch-typing is so common today, having been accepted by the masses.

The question for one company though is how to measure that display latency i.e. the time it takes for the system to detect and register a touch, thereby launching an app. App streaming company Agawi has come up with a solution called TouchMarks to make accurate and quantifiable measurements in this area and the Lumia 928, while not the worst, is far behind Apple.

Devices compared include the iPhone 4, iPhone 5, Galaxy S4, HTC One and Moto X in addition to the only Windows Phone, the Nokia Lumia 928 found on Verizon. From the write up:

“As you can see, the results are remarkable. At a MART of 55ms, The iPhone 5 is twice as responsive as any Android or WP8 phone tested. All the Android devices’ MARTs fell in the same 110 – 120ms range, with the WP8-based Lumia 928 falling into that bucket as well. (Incidentally, the ranges all span about 16ms, which is expected given the 60 Hz refresh rate of these smartphones. 1/60s = 16.6ms)”

Indeed, the Lumia 928 had a response time of 117 ms whereas the iPhone 4 was at 85 ms and the iPhone 5 was even better with an extraordinary 55 ms response latency. The iPhone 5S, released this past weekend, had yet to be tested.

Why the discrepancy? Agawi has their theory:

“…Apple’s touchscreen hardware is better optimized or more sensitively calibrated for capturing and processing touch. Another possibility is that while the Android and WP8 code are running on runtimes (Dalvik and CLR respectively), the iPhone code is written in closer-to-the-metal Objective-C, which may reduce some latency. In future TouchMarks, we’ll compare C/C++-based Android apps to Java based apps to determine if this is the case.

Regardless of the reasons, the conclusion is clear: the best written apps on iPhones will simply feel more responsive than similar apps on the current gen of Android devices. (We speculate this might be a major reason why the iPhone keyboard generally feels better than the Android keyboard to many people.)”

The results are fascinating, and while we can debate whether or not that extra 50 ms would really make a difference in user experience, it seems Apple has once again bested Android and Windows Phone. Microsoft is aware of this problem though as noted in the above video, where Microsoft Research is working on 'High Performance Touch'.

Agawi has open sourced the hardware and software behind TouchMarks, so people can peek at what they are doing (and try to replicate the results). The company also plans on doing future tests on other devices to see how they stack up, including the new iPhone 5S. We hope those future tests include different Windows Phones too because for all we know, the Lumia 928 is the exception and not the rule. Still, it seems clear that Apple has spent some time considering this area in engineering their phones.

Will these results cause companies like HTC, Nokia or Samsung to reevaluate their approaches to screen calibration? We hope so as this is one important area that manufacturers won’t want to skimp out on.

Behin"D' ... Dan... :)

Bah.  I blame stopped spell checking for som reason, need to reboot :/ Fixed.

MediaCastleX says:

Don't worry Dan, my fingers seem to be skipping keys a lot lately too...although on my Lumia 925, I detect some latency too. At least when it comes to some 'th' words... =P

Xaphoon148 says:

Impossible to notice anyway, but congrats Apple, your engineers are obviously worth their salary :)

michail71 says:

I'm not so sure it's impossible to notice. I can type much faster on an iPhone. I used to think it was because the keys are closer together. On other devices I feel as if something slows me down.

jjmurphy says:

I feel the same way michail.  I prefer the keyboard of WP, but for some reason, the iphone always feels right.  I don't feel like that on the ipad though.

TechAbstract says:

I prefer the big buttons on the keyboard of the iPhone. WP's keyboard is so narrow, it's easier to make mistakes.

AaronSmith86 says:

While at work I read this article.  I own a 928 and I work with people who own a iPhone 5 and a GS4. I've always thought the Windows Phone keyboard was the best, and after today with this article and comparing the phones directly.....I still prefer the Windows Phone keyboard. It was by far more accurate than the 5 and GS4. Not to mention the autocorrect on iOS is by far the most annoying thing when making a mistake. Truth be told I felt my 928 was far more responsiv than both the GS4 and iPhone 5.

I couldn't agree more. I too have used both iPhone and WP8, as well as BB10, and I prefer the WP8. The WP virtual keyboard has a more complete function, and is easier to use than either of the others. IMO, the iPhone is the worst keyboard of the three.

Skiman80 says:

I agree, after using mu Lumia 920, I am always hitting the wrong keys on the iphone. The screen is just too small

stephen_az says:

If you think you can tell the difference, which is measured in milliseconds, you are either a) not functioning in this dimension, or b) possess something other than a higher primate's brain.   

xratola says:

It might be because of the screen size, since I can type quite faster in a 3.5Inch display than a 4.5Inch one. :)

nizzon says:

Thats bulllshit. You sense these differenses in ping when playing online games on PCs.

@stephen_az did you watch the embedded video from Microsoft? 50 milliseconds is easily discernable by the human eye.

As a PC gamer, I can sense a lot of tiny ms changes

Nathan Bael says:

Agreed, just like back in the day I wouldn't use an infrared wireless controller on my super nintendo because of the lag, same for early cordless mice.
I think the delay is noticeable because often I'm 2 letters ahead of what is displaying on my android than on my iphone. Haven't bought a WP8 device yet, but plan to if the 929 is awesome. I just hate an app size download limit.

h_portal says:

While I enjoy typing on my iPhone 4, I preffer the experience of typing on my 920 (Autocorrect warns you before kicking in, next-word prediction works awesomely and learns from you). My laptop is not working at the moment and I'm using One Note on 920 for classroom notes! 

Rem97 says:

Don't know if its just me, but I've always thought that iPhones seem very responsive, more so than any other phone. However that's probably more down to the OS than screen latency.

nizzon says:

Most certainly both.

Agreed. Great job by Apple. This! Is why competition is good for us all. Today they raise the bar, tomorrow it will be us. Progress @ its purest. Let's keep keep going forward.

Rubios says:

It's pretty noticeable for me, and 5s seems to be even faster.

txDrum says:

A difference of 60ms is definitely noticeable if you've played even semi competitive games. 55ping is much better than 130 ping. This is some interesting engineering by apple.

infosage says:

I pulled out my 920 and decided to compare the results on my phone to the results in the Microsoft Reseach video.  

I started by hitting the search butten and just sliding my finger back and forth accross the top row of the keyboard.   I compared the lag to the results in the video, and it appeared much closer to the 50ms lag (67 seconds into the video)  than the 100ms (57secs into the video) lag.

Then I decided to open up Fresh Paint, and paint some squiggly lines (like in the video).   I still felt the lag was much closer to 50ms than 100ms. 
I know... completely non-scientific, but what are you guys seeing?

Doesn't surprise me at all.  There's always a major delay when in that initial touch and movement on my Lumia 920.  It's pretty annoying.

pranav rai says:

Weird, I didnt notice anything of that sort.
Everywhere in the OS?

It's particularly noticable on drawing apps like Draw Something.  I also notice it a lot on Fragger, where I need to make just a TINY adjustment in throw power or direction.  You have to move your finger a certain distance before it realizes it needs to respond, and then you can make micro adjustments after that.  But that initial move not a short distance and it's a killer sometimes.

I put it in the article, but Microsoft demonstrates this exact issue very well in this video:

Yes, but I feel like the video covers the second part of a two part problem.  There's initial response time and continued response time.  The video seems to touch, ahem, more on continued response time.  My issue, and what I think the tests in the article were detailing, is the initial response time.

MA83 says:

I can tell from practical experience though that my wife's 928 seems WAY more responsive than my iPhone 4 (company phone).

dc9super80 says:

The iPhone lags for performance reasons more than anything else.  But agreed, lag is lag and the customer is only concerned about there not having lag, regardless of its origin.

DavidinCT says:

My wife still has a iphone 4...I use it time to time and my 928 is way more responsive.
But, her iPhone does not have problems like the touch screen stop working and other issues that the 928 has...

he_shark says:

Well my 920 feels incredibly responsive, so I think this is one of those tests that's great for tech nerds but in real world doesn't really make any difference. And does the iPhone actually work with gloves on? I thought that was something on Nokia had, and that's something which really does make a real world difference.

Yup, it's certainly an interesting question regarding "does it matter?"

And correct, Nokia has that tech, although a few other companies are now starting to use it (it was developed by Synaptics, Nokia merely licenses it).

walter1832 says:

Yes I agree...
The engineer in me says "This is very interesting"

The end user in me says, "Who gives a F since I can't really tell"
The skeptic in me says, "Agawi was paid off by Apple"
The nerd in me says "Screw you, WP is better..just because"
The ATT customer says "Where's my damn Amber update"
The fat guy in me says "Whats for dinner"

OstiPosti says:

Agreed 920!!!!!!

ChrisLynch says:

HAHA!!  Awesome comment!

marantaz says:

The rest of us can relax now...Walter1832 has won the internet, and its not even 11 am where I am! Damn!

Antistatic says:

Thanx for a great laugh walter1832! :-)

dasfoto says:

Do each of them have their own name and do they ever tell you to do bad things ... like buy an iPad?

JackG058 says:

Lol, +920 without GDR2/Amber to Walter.

louisoneal says:

You win in life my good sir.

rahul.sharma says:

Reply of the day, thanks for the laugh

Neo Nuke says:

One of the best comments I've seen on this site. LOL

I can tell you right now that my iPhone 4 has never worked for me while I was wearing gloves. It barely responds when my nails are a little long. Really don't get the statistics in this article. :-/

The Synaptic tech for Super Sensitive Touch came after the iPhone 4. Apple could license it for their devices though if they want to.

Arsenic17 says:

Super Sensitive Touch is just as revolutionary of feature as the TouchID finger print reader is..but it got literally no press and everyone didnt beat their meat all day about it. iSheeps go BAAAAA!

Well, blame Synaptics who don't advertise ;) Also, since Nokia didn't invent it, it's not unique to Lumia phones ergo less of a selling point to boast about.

Also, TouchID, AFAIK is unique to Apple--it's their tech and TBH, it's pretty damn nice to use.

Arsenic17 says:

While no one can argue this tech has been attempted before, it may finally be done right now, does it really matter. It is not a game changer like it is made out to be. They spent s long talking about it, but really is it that big of a deal. Maybe I appreciate it less because I never lock my phone. It is always open. Unless youre a player trying to hide you hoes from your old lady, I dont see the point (outside of work phones). And even then, a small % of sheep are corporate users.

I think that's why it kind of is a game changer. I don't lock my phone often for two reasons:

(1) It's a pain to unlock each and everytime

(2) You look suspicious (or make others feel you don't trust them)

TouchID solves both of those problems and it does it very well. I think a lot of people don't use PINs because of those two issues, so if this "solves" that, then yeah, kind of a big deal ("game changer" though is a relative term, YMMV).

mrcraggle says:

I can type my pin into my phone just as quickly as someone can using touchID. As for your 2nd point, maybe you shouldn't shift your eyes around so much when you do it :P
Right now, I don't think it's much of a "game changer" as a lot of journalists have been calling it. You can use it to unlock your phone and log into iTunes to purchase music with the latter being something I have no interest in anyway. It could be something more significant if they let 3rd parties make use of it but if Siri is anything to go by, they won't and it'll be something that Google or MS can leapfrog.

"I can type my pin into my phone just as quickly as someone can using touchID."

Honestly, I can't see how that is possible. I don't move my thumb at all when on TouchID, just press the Home key and hold it for a 1/2 sec and it unlocks.

Unless your passcode is 0000, I just don't see how that is physically possible.

I too am having a really hard time seeing it as a game changer.  I don't think a substantial amount of people will suddenly start locking their phone because of it.  People would be dealing with the hassle of a pin already if they were actually fearful of losing their phone and the content on it.  A finger scanner isn't going to suddenly change their view of securing their data.  If someone wasn't using a pin, but they start using the finger scanner, it's more likely because it is one of very few new features on a 5s or because they are trying to look cool.  Most importantly, the feature has to actually serve its purpose for it to be a game changer.  The fact that the service was hacked in how much time...really prevents it from being a game changer right there.

HTC has been scanning fingerprints since at least 2007. It never changed the game.

Yup, and I have an LG Expo from 2010 running WM6.5

It sucked. (the phone was great though).

Are you really saying that you would suddenly start locking your phone because touch ID would save you the inconvenience of an extra 1s and a couple extra button presses it takes to use a pin over touch ID?  I am not even sure what to say to that, but certainly nothing good.

jsnod25 says:

But if Apple licensed it, it would cost them a couple dollars, but they would claim it was revolutionary and completely new, then charge an extra $100 for the "new" feature, so maybe they will save it for the 6s... But then when do they but NFC and wireless charging in? 7s!?!??! So many single features to add and market as a new technology.

louisoneal says:

I know right! If I had gloves on it was over for iPhone 4s usage. The phone would just give up, it was sad. Now my 928 on the other hand worked like a glove. See what I did there :-)

npoe says:

I think that there is a chance that the screen does have the delay in order to filter all mistakes while using the phone. I.E. a bad contact of the finger with the screen or a slight and short lift of the finger with the screen.
That happens a lot to me and the phone seems to not launch or do stuffs that I didn't want to because the "delay".
So, to me that's a feauture.

gemini5150 says:

I 2nd this proposal.

hsn97 says:

Who cares? Lol. WP all the way.

tcprodigy says:

No one cares about this test. 55ms to 125ms is an unnoticeable difference

Two things:

  1. I bet if Windows Phone had won, comments here would not be "no one cares" ;)
  2. It has not been demonstrated that the difference in unnoticeable. It's an interesting question if it is/isn't, but let's not assume it does not matter

fpostrow says:

"It has not be demonstrated..." who didn't not be demonstrated it and where's my GDR2 for my ATT Lumia 920? :-)

RyanAMG says:

Dan do you think the 925 may have done better?

Honestly, no idea. I have no idea if Nokia even measures/considers this when making phones. That's why I find it interesting.

abel920 says:

That's because Nokia spend q much time with the phone's camera that they have no time to focus on more important features of the phone itself.

tamas305 says:

Exactly. But that's true of all fans. They trivialize positive things about their competitors and exaggerate positive things about their team.

baron1996 says:

Okay hands down the best reply to any comment ever it does matter as much as each pixel in the camera or screen

I agree with Rubino when he said that if it was WP, everybody was celebrating.
My brother has an Iphone 4, and I have Lumia 520, my little sister 920.
My little sister to my brother is near the same.
But my lumia 520 is different, depending or what I do. If it is native thinks like contacts (people) and calling I guess I won (since I am dual core). But when comes to apps, I always believe that Apple has the touch more responsive.
I guess it is a kind of calibration and also because NXT kernel is a 21 years old. Our kernel is a kid compared to Apple's kernel. And Yes kernel is the main way how to improve software contact with hardware.
As active member of XDA, since my Android's days, when it comes to Google's OS, the problem is the core. They don't like to accept it, because it is not a good propaganda for them. But the way is Dalvik cache is conceived , always will be some kind of noticeable lags.
But, I have to say, any Android test should do using a Nexus. Pure android has less issues, and remember all the virtual machines for devs, usually takes a pure android experience for testing. Android improved a lot, the last kernel 3.7, is more responsive, made the multitasking much better (less anr) and less consumption of power. Rooms for improvement? A Lot, at least Google is trying to do their best to fill the gaps of their OS. Will perfect like iOS? I guess never, but close.
About MS, I thoght, because I still don't know how Windows Phone truly manages the things, and how NT Kernel is well designed. But some said that Windows Phone 7X is better responsive. I guess this is because the maturity of Windows CE Kernel, developers could understand how it works (and their limitations) and improve the way it was designed to a perfect answer between Hardware and Software.
Windows Phone 8 in other side was made running out of time. I guess the GDRs will improve a lot the experience. My lumia 520 improved with GDR2. Peharps with GDR3 will be better. Room for improvement always will be.
I just wonder if MS is really doing and put all the efforts to do that. Because AFAIK NT kernel could much better than NXT kernel. But they need to improve the things. Look to Google, they have the worst core system, but they are spending all the resources there to improve their limits. MS should follow the example.

cannon#WP says:

1. Wholeheardily agree
2. I think it would be near impossible to demostrate the difference. We'd need some double blind type of test, but for that you'd have to find people who haven't used an iPhone or Android device. Those people are becoming few and far between. Once you've used one of those 2, you're more than likely going to have a bias to the one you tried first and even with a keyboard skin, people will instantly know which device they're using.

npoe says:

I think the delay is a feature to prevent unintentional launchs or unintentional commands in apps. More than once I don't make perfect contact with my finger in the screen or it does lift for a split of second by mistake.
I think that is an intended feature.

While I completely agree with you, I really do believe that the attitude of the average user will be, who cares. It certainly seems obvious that Apple thinks they will care.

Keep in mind that lots of things in this world are perceptible, but that doesn't mean it matters to most people. There are some people that notice the "rainbow effect" from DLP projectors while others are completely oblivious to it. Some people with crazy good eye sight can actually notice the "screen door effect" on LCD projectors while others have no idea it's there until they walk up to the screen. Some swear they need a 2ms display for gaming while others are plodding along happily with something far more meager. Some can only game with a wired mouse while others are happy with their wireless mouse. Just because it is perceptible, doesn't mean most people will notice or even care in actual daily use. I really believe that this is one of those things where most people either won't notice or care. I am one that didn't notice switching from a 4s to a 1020. It never even crossed my mind that there could be a difference.

bpmurr says:

If you were playing a fighting game or FPS you'd notice. However, we don't have many of either on Windows Phone.

mikosoft says:

Oh, yes, it is very noticeable. You can notice a 20ms difference with both your eyes and ears.
When I compare responsiveness of my L620 with a friends iPhone 4S, it IS noticeable. It is even noticeable with an iPhone 3GS (still faster than my Lumia).

rdubmu says:

I wonder how the Lumia 920 would have faired with its LCD screen instead of AMOLED on the 928. I have always prefered LCD verses amoled. Just my preference but the colors look more real and the screen seems much more responsive.

teoami says:

Does not really matter about the panel tech, it is really the digitizer and the coding behind it that matters.

nokiauser911 says:

Android are laggy coz there were not meant to be on touchscreens! But WP is meant to be on touchscreens!! Why lag?? Why??

absolutshame says:

I wonder if the screen sensitivity was on high?

kwajr says:

That's what I wondered

Zeroplanetz says:

Was thinking the same thing

jason8957 says:

I was neither wondering nor thinking about that.

I prefer my 920 to typing compared to my wife's iphone any day, spell check on the iPhone 5 is not very intuitive, and I find hitting the sliders easier on my phone as well, many times I can't get the sliders to change on her phone, how many seconds are wasted there?

I tried enabling spell check on my iPhone 4 and iPod touch and it indeed sucks. However, I love autocorrect on my Lumia 810 and 920.

dc9super80 says:

What does that have to do with the screen test?  Are you being defensive for being defensive sake?

funkyGeneral says:

It could be a comment on the effectiveness of the keyboards, as it was proposed the response time may be a factor in people preferring the iPhone keyboard.

Correct funkygeneral, it was a comment on keyboard effectiveness, no defensiveness, I own both products, I am looking at overall usage time using the keyboard, the response time of the screen, while significantly better on the iPhone, there are other factors at play. If I was a huge gamer then the screen display latency would be more important to me.

dc9super80 says:

Good point.  As an iPhone user myself, I must say we are severly lacking in that area.  Personally I think we need two things to have a better typing experience, a wider screen and additional typing tools i.e. gesture typing.  I use gesture typing on my Android devices constantly.

dc, thanks,I love the typing predictive algorithm, I am all for gesture typing for user choice, but I can type by moving my thumbs faster I feel, especially words with double letters.

Who's being defensive? That would be you. I, on the other hand, was responding to Inside man 55 and his comment of how he feels about using spell check on his wife's iPhone. Oh, and also expressing my personal opinions, which, last I checked, I have every right to do. Nothing more, nothing less.

dc9super80 says:

Take it easy, I already retracted and conceded that it was a good point.  At least acknowledge my acknowledgement of being erroneous. HAHA

Metal chick, you are awesome, I love your right to express your opinion, I got in trouble with someone yesterday for arguing why they gave Sam a -1 for no reason. As long as no one does that we are cool lol :)

tylerb2002 says:

I agree on the sliders.  I had an iPhone 3GS (low res screen).  When they released the 'retina' screens and I updated iOS, the buttons all seemed to get smaller.  It's like if a button was 20x20 pixels on my 3GS, when I updated it suddenly became 10x10 pixels (or maybe 20x20 on the iphone 4). 

Your comment reminded me how annoying that was.  Of course, i switched to Android soon after that and will never go back.  The new Lumia 1520 is getting me to consider making the jump to winphone though!

Tyler, Glad to see I am not the only one, after using my 920 that annoys me to no end, lol I find that funny regarding your comment on Android, yes the 1520 will be one hell of a phone / tablet. I call the 1520 Nokia BALLS for Big and Large Lumia Slate. :D

Yeey...who gives a damn.

skshandilya says:

I guess that something maybe wrong with this test. WP, being native, like iphone, should not be close to Android(Dalvik). Launching an app is not the correct way to test this.

Robborboy says:

Well duh. The latency on the 928 and Windows Phones in general is awful.

mr toes says:

Thank you, someone realistic, no the latency isn't great on windows phone and needs to be improved.

WP7_Genius says:

Again benchmarks mean crap. In real world use, my L920 games nice, I text and email nice, and when I touch it has a brief animation and opens. Again this is a "who cares topic"

That's kind of a terrible position to take as it implies there no room for improvement. Technology is based on faster, longer lasting, more accurate and being smarter. Saying "who cares" is not really what technology and its development is about.

Once again, I bet if we had said Windows Phone won, the comments here would be gushing about Nokia or something, so forgive me if I take these "who cares" comments with a grain of salt ;)

Ankmeyester says:

I really dig the neutral "let's learn from this and appreciate good competition" motto adopted by you today :) More users need to inculcate this attitude; Since a demanding competition calls for better innovation in all the right directions and at the same time: faster :)
I agree, more comments would pour in with each user gloating away if WP was on top! I'm glad at least that a good chunk of them decided to turn away quietly than degrade the stats. We're better than Molly c'mon! ;) :P
Anyways, I hope this issue is worked on and we get ahead in due time! I have that trust in Nokia (regardless of which corporate giant it is sucked into) :)
Cheers! :)

AliNSiddiqui says:

Completely agreed. If WP fans keep downgrading the results then manufacturers won't care for this. WP fans here should learn to take the hit and accept that iPhone, currently, has much better latency on touch.

lubbalots says:

I'm all for improvement and innovation but if my senses can't tell a difference, then who cares. If 99% users can sense a 50ms difference, congrats to cock and team.

typhon62_1 says:

I agree 100%.  Most people think they don't notice, but a lot of this type of stuff is noticed subconsciously  and that may affect your overall feel for how something works.  Apple knows this and their low screen latency times are no fluke.
Engineers are a competitive lot and I'm sure there are some Samsung, HTC, and Nokia engineers digging into their designs to see what they can do to speed up their stuff up.
Overall I'm not too bugged by getting beat by Apple, its the Samsung S4 beating the Nokia that irks me.

Fanboys(fans) in general will apllaud any "feature" that one has over other platforms no matter how small. That goes for blender wars/car wars/musician wars/ you name it ppl will do the same thing online so it is a bit unfair to take it with a grain of salt just based on the fact that Apple won this "feature".

WP7_Genius says:

I mean does it really matter how fast screen is? I touch it, it works, can we even see this in real world use? I like my 920 and would switch just cause its unnoticeably slower to the human eye. Its smooth and responsive enough for me. But that's me others may really be bothered by this. I understand tech always needs to advance but I'm sure apple needs some advancement as well in some technologies.

Yes, watch the embedded video.

majortom1981 says:

 Was this with or without touch sensitivity on high ?

enahs555 says:

I kinda new it all along. Just because when I play Temple Run on my Lumia 920 vs my friends iPhone 5, it is so much easier and I do so much better on the iPhone. Despite the fact that I have a bigger screen.

Ratman826 says:

Dude, temple run hasn't fully being optimized on WP8 yet

Dazzi says:

Same here mate. Temple Run is way better on my sons ipod, than my L920 -- well done Apple.

ChrisLynch says:

Sorry, but it's not Apple that made Temple Run better than the WP8 version. It's the folks over at Imangi Studios have not optimized the app on WP8. Ever remember when Wordament was first released, and the Lumia 900 had "screen performance" issues? It wasn't the phone. It was the app, which they fixed. Same thing needs to be done with Temple Run.

Dazzi says:

I like how you're quick to blame the developer, but what if it isn't the developers fault? Here's a link courtesy of Mr Rubino, please watch to see the difference between iPhone 5 (55ms) and Lumia (117ms), in terms of response times. This video shows the difference between 50ms vs 100ms.

Binson#WP says:

This is the last straw for me. I'm switching to iPhone 5s.

walter1832 says:

I'm jumping ship when they come out with the iPhone 5st (super touchy).

Binson#WP says:

No thanks. If they do that, I'm jumping back to my 1020.

typhon62_1 says:

I noticed that too :)
Nice to see another hardware person on the site!

Rubino said iPhone is better than windows phone at something....QUICK KILL HIM!!!

walter1832 says:

Done aaaaaannnnd done. Should I mutilate the body? JK, don't call the cops!

iPhone beats WP
Who cares, it's only 50 ms, LOOL., doesn't matter
WP beats Android by 5 ms and is slightly more responsive than Android: OMGGGG, Android is LAG LAG LAG LAG

I think Android's lag is less due to the screen latency and more about the core processing of the OS and multitasking. Very different issue.

chocka says:

And I think WP lag is due to run time interfaces than screen latency.
"Another possibility is that while the Android and WP8 code are running on runtimes (Dalvik and CLR respectively), the iPhone code is written in closer-to-the-metal Objective-C, which may reduce some latency."

What happened to puremotion HD tech of Nokia, they should have picked up a non amoled display...these screens have different characteristics and may be there test was more optimized for iPhone

majortom1981 says:

They Also didnt say if touch sensitivity was on or not

Hate to break it to you, but PureMotion is just the 60 Hz refresh rate. It's common these days on all high end smartphones, Nokia just gave it a funky name aka gimmick.

majortom1981 says:

Touch sensityivity is not the puremotion. It is the part for being able to touch the screen with gloves. it is off by default. I notice my phone reacts quicker to touches with it on but its off most of the time because it uses up battery.

Kram Sacul says:

Daniel, Puremotion isn't about refresh rate. It refers to the lack of or reduction of ghosting/blurring when scrolling.
Good article by the way.  All the "who cares" or "you can't notice" responses are hilariously ignorant.

I can obviously notice the difference in the video, but I do not notice it in everyday use. Maybe I am just not as sensitive to it as others are. The brain is an amazing thing, and most will adapt to the delays without notice. I am not advocating that the tech shouldn't be improved, but I don't think it is a big deal as it is now for the majority of users.

jlynnm350z says:

Yeah,I'll miss those .03 nano seconds every time I open an app. By the time im 98 they'll add up to about .o2 seconds out of my life waiting. But apple will use this clearly as they are so revolutionary

It's also about typing, which is where it matters more.

I have to strongly disagree Dan.  IMO, it's all about drawing.  A person that can type 60 words per minute would average 1 key stroke every 166ms, and 80 words per minute is a keystoke every 125ms.  I have hard time believing these latencies affect even the fastest typers.  Anyone capable of typing faster than that has to be in the .01% crowd.

blackhawk556 says:

Does anybody's 1020 select options on the screen when they merely hover their finger over the screen? I've been able to scroll sometimes by hovering my finger up or down. It only works if my thumb is warm I've noticed. Same happened with my 920. Figured it had to do with having High sensitivity on.

Jf.Vigor says:

Yup happened to me on my 920

xrs22 says:

^Doesn't give a shït, I like my 928, not as much as I liked my 920 but had to switch.

umovies says:

misleading, as wp could have the same screen but ios is a slimmer os, just like mac os vs windows 7 or 8, native drivers in ms has always sucked. in audio world we had to use asio driver to eliminate latency in music. And still do, ergo I think this is Microsoft fault not Nokia or Samsung, or htc, or iPhone superiority either, they just reaching for straws here.

Lundon44 says:

While the iPhone keyboard may "generally feel better" they also have the most auto-correct disasters of any phones in existence. I'm sure we've all see the spellcheck fail threads and jokes going around the net. Every wonder why 90% of them are iPhones? This article is your answer!

Kieta says:

I always said Apple has the most responsive OS. It's their GUI that turns me completely off.

what about pure motion hd+ displays? does the 928 have one? What about a Lumia 920 or a 1020? ... just curious ;)

PureMotion is kind of a gimmick. It's just the 60 Hz refresh rate that all high end phones have or have had for sometime.

lubbalots says:

Surprised you didn't mention this a long time ago.

When the 920 launched it was not as common--iPhone and a few Android devices, maybe. Fast forward nearly a year and yeah, certainly not unique.

sumothong01 says:

Still like my 928 more...

Zomby Jeezus says:

What about the 1020 or 925? Let's try thus test when the new lumia releases come out in november

Why post anti-Windows Phone information on a windows phone community website...

trickym81 says:

Because it's a "news and information" site not a "stroke Microsoft's ego at all times, happy fun and sunshine" site.

Yup, that and I found it interesting because it affects all modern smartphones. It's an interesting topic for discussion and maybe Nokia will respond to it i.e. by calling it BS or improving their displays.

CommonBlob says:

This needs to get better. From a piano synth developer!

theefman says:

Definitely has to be shown if this make a measurable difference in practical use. My 920 feels very sensitive with touch sensitivity set to High and I don't ever feel like I need to tap more than once to get my input registered and it really feels super sensitive. But I guess this is another stat that apple will showcase at their next "magical" event to prove they are the best....

The thing that annoys me on the 920, is when I'm in an app (ESPN, Newser, etc) and try to pan horizontally, it will jump to a link. Wasn't sure if it was bad app programming or a a hardware issue. Sounding like it may be a hardware issue now.

mr toes says:

I honestly believe windows phone 7 was much better for screen responsiveness and latency than windows phone 8, and the iPhone is admirably quick to respond, doesn't surprise me.

+1, I wrote the same thing.

RodimusMajor says:

I accept that there's room for improvement, and I'm certain future Lumia models will take this into account, but I will also say that I have absolutely zero problems with screen response time on my 1020, so either I'm not very perceptive or this is one of those things that's far easier to pick up with a machine than human senses. Like infrasound or something.

trickym81 says:

Everyone who is saying "Who cares? This means nothing!" would be celebrating if a Lumia came out ahead of the iPhone. Just saying.

Wish they had this test when wp7 came out. I could swear screen response time was better than wp8.

NIST says:

Yawn. When am I ever going to compare latency in ms with a friend at lunch with their iPhone? An interesting test, meaningless stat, useless selling point. Next.

Is it? It's not about the actual numbers but whether it affects daily usage on things like typing or playing a game. I wouldn't be so quick to dismiss.

NIST says:

You have a solution in need of a problem.

You haven't demonstrated that at all. I believe in tests, science, results, and numbers not just conjecture in comments.

Above I see test data showing the iPhone 5 is faster. Below I see you saying it doesn't matter with no evidence to support it.

Also, see this video for the difference between 100ms and 50 ms

NIST says:

This is akin to testing the carpet pile density of 4 high end cars.

mr toes says:

Actually you can feel the difference between iPhone and android/wp8. The iPhone is indeed more responsive, something wp8 needs to improve on imo.

Aryan Angel says:

Brb. Looking for the nearest apple store in here maps.

dosto says:

When I had to get a second phone for work, I could have chosen any phone (it's my $); I chose the 925 and have no regrets. It's a great phone and I don't notice any lag.

Zeroplanetz says:

I don't know about the iPhone 5 but my 920 dances circles around my friends iPhone 4s on speed for just about everything you can compare.

uselessrobot says:

I've used a coworkers iPhone 5, and have had iPhones side-by-side with my Lumia 920, and I can't say I've noticed a difference at all in responsiveness. Furthermore, my iPad 2, basically running iPhone 4S hardware, seems decidedly less responsive than my phone.

Could it be that the Lumia 928 has inferior performance compared to the 920? Is it a GDR2 issue?

Or are the differences generally imperceptible? This strikes me as a bit odd to say the least. But I'm not surprised Apple would be at the top because they generally do a great job of optimizing hardware and the OS.

cybermoose89 says:

Cant say iv noticed my 920 response great to what ever app etc i use

TheDarKnight says:

Why does this matter? Its in milliseconds, who cares, or notices, they can't even test it without all these equipment and crap.

Dazzi says:

I care because this 'might' be, the reason why games seem to be more responsive on IOS than WP8?

TheDarKnight says:

Get an ifruit then.

Dazzi says:

Hmmm, such an intelligent reply TheDarknight, not! These kind of comments remind me of that WP8 advert, which took the Mickey out of iSheep and fandroids -- isn't it ironic that some WP8 fans are the same, if not worse. Ha ha ha, too funny.

WPBlox1989 says:

And this is not a GTA fansite but a Windows Phone news and info site, TheDarKnight. So go post those GTA V jokes somewhere else 'cause this joke is not funny and neither it is cold.

Ultimateone says:

Would have preferred to see a 1020 in that testing

Four Whey says:

The conclusion made by the author regarding the latency for WP being related to the touch API being written in CLR is most likely false.
This is a core component of the OS, and is most likely not written in managed code.  If anything, I'd guess is unmanaged C++ and is very optimized and quick. 
They should test other hardware, this could be a limitation of it.

NIST says:

Comparing completely different hardware with a completely different OS written different languages with different processors and trying to run a test and then normalize the results is completely humorous, and yet an article.

rikycaldeira says:

It seems they tested with a custom app, so it's not relying solely on the touch API (which I agree shouldn't be written in anything but the lowest level possible).
But even if their app is almost running on the metal itself, I don't know how WP manages native apps and whether CLR might indeed make some kind of difference anyways.

jmunchies1 says:

Maybe that is why double tap to wake with glance rarely works for me.

I was just complaining about this the other day when playing Modern Combat 4.  The touch latency of my Lumia 920 is awful, and it shows in comparison to my old 4s.  When you tap on the screen to shoot, move, or do anything, there is about noticeable lag in response (and other games as well).  With my 4s, the touch would result in an immediate reaction on screen.  This is one area I wish could be corrected with software, but I know an update can't do it...
Here's to hoping Windows Phones start incorporating better touch screen tech....

Jf.Vigor says:

Thats not the screen, that's just the graphics chip being inferior or bad game optimization

True, and I should have mentioned that.  Adreno 225 just doesn't cut it today, and it shows.  However, the fact remains that even if the game were optimized (and/or the GPU was stronger), the touch latency would still be contribute to the entire experience being inferior....
Whether or not it would be noticeable to the user is a different story....

gioany says:

Don't agree however someone filling us with shit again, make your own mind up.

sicnus says:

It took me 420ms to not care about this test & its conclusions.

You don't find it odd or fascinating, even from an engineering point, that the iPhone 5 is so far out of the norm in terms of latency? I do. 

sicnus says:

Ok, but I'm not an engineer, I'm an end user. Think everyday joeuser will notice this difference? I don't.
