battery performance

Yesterday, we mentioned that several readers were having terrible battery life with their Nokia Lumia 920 Windows Phone. Some batteries barely lasted half a day while others steamed on with fantastic battery life.

We had a few suggestions to disable the NFC to improve battery performance. Yesterday, with NFC enabled, my Lumia 920's battery only lasted six hours before drying up.  The 920 also got warm throughout the morning. Today, after disabling the NFC the Lumia had 62% battery life remaining after ten hours and I didn't experience any warm spells.
