I'm trying not to micro-manage the battery, so I don't have stats to give you, but I will say this. The xl is the first phone I have had where I don't feel the need to charge it overnight and I don't constantly check it during the day to see how close to dead it is. I charged it yesterday around 4:30 my time. It's now 7:18 am and I'm at 70% after being on it a lot last night and for about 45 minutes this morning. Relative to other phones I have had (Droid Turbo, S4, DNA, Thunderbolt), that's excellent battery life so far.
