The first day I got my 920, I let it drained and did a full charge of 12hrs. I got it off the charger around 10 am, and I left it at home(cuz I was still using my old phone at that time). At the time when I got home was around 5pm, and the battery was still showing 100%. So it was about 7 hrs off charger.
Last night, I went to bed with around 92% of battery, had everything turned off, all background tasks were blocked. And this morning I only had 45% of battery left. It was about 10 hours off charger.(Yeah, I had 10 hrs sleep, feeling great right now)
Do you think it's normal to have such big difference? The only thing was on last night was the "battery saver, will be turned on when battery is low". And couple notifications on my live tiles. That was it. I don't see any changes would cost this drain.
