Just got my Incredible 2 last night, replacing an original droid. Charged it up to 98% before I went to sleep, when I woke up it was at 16%. I'm freaking out a bit, because I need this phone to be reliable when I'm on call.
I've read that maybe the battery needs to be charged to full a few times and I'll make sure to do that.
Wifi was enabled, which was how I used my Droid with no problems. Turned that off for now.
I do use the Battery Indicator app. And had the phone set to automatically sync the weather, although it looks like that only happens every four hours according to the settings.
I turned down Brightness this morning, but that shouldn't have been a factor while I was asleep, as the screen was off.
Anyone have other ideas that I could do to make sure that doesn't happen again? Or reassurances that their phone acted like this and then after charging it a few times it was OK?
