Does Wifi Stay On with Phone Off? Battery Loss Overnight
I realize how dumb of a question that is. I know there are several battery threads out there, but those seem to be discussing leaving the phone on overnight.
Here's my issue: I turned off my phone (with wifi still active) last night with about 32-34% battery according to the battery widget. As in... I turned the phone off. Completely off.
I woke up this morning to find myself with 13% battery and the warning that I needed to plug my charger in.
...scratching my head as to how that's even possible.
Thoughts? Could I have some sort of module on the phone that is staying on overnight and slowly draining it?BB Storm 1 => Incredible => Galaxy Nexus

Just to be clear, it sounds like you let your phone go to sleep, you are not turning it off. Even when asleep, it does some polling every now and again to look for app updates, email, text messages, etc. Also, if the cell radio on that will use up juice periodically.
If you don't need to get updates while you sleep, I suggest putting it in airplane mode before you go to bed. With all the radios off it uses almost no power.
I still can't believe turning on the phone zaps 20% of the power in one fell swoop. Baffled.BB Storm 1 => Incredible => Galaxy Nexus
