I've seen countless threads about battery problems on the iPhone 4s but I haven't really had any issues. It was fine immediately out of the box for the most part and after letting it drain completely to dead and then giving it a FULL charge to 100% via the wall plug it's even better than before. I've had it unplugged from the charger for a good 20-30 minutes now and it's still at 100% since the full charge. Even before doing this while letting it drain last night I left it by my bedside and it started at 28% and when I woke up this morning it was still at 25% and that's with bluetooth on, wifi on, location services on for 3 things, etc. Am I just lucky?
