Last night my phone had about 5% of battery and I forgot to charge it. This morning the phone wasn't turning on so I left it to charge all morning (by using the same way I always do, by USB). I'm trying to turn it on now after about 10hours and it won't turn on. I see the white little when I plug in the USB but the actual phone won't turn on. I've tried the battery pull to no avail. Any ideas? This actually happened before, same exact thing, but it worked after a few battery pulls.
