This didn't always happen, but for several months now, if I put my ipod touch to sleep for a while, there is a chance that while asleep, not only will the ipod crash, turning itself off, but the battery rapidly drains. So, if the charge was at 100% the night before, the ipod will have crashed by the next morning and drained battery to 0%. I know this isn't just the battery draining to 0 and appearing to crash the ipod, because several times I've caught it before it goes to 0%. So for example I'll leave the ipod in sleep for a couple of hours when it's at 100% battery, and return to find it completely turned off, and I'll have to turn it on, and find that it has maybe 30% battery left. Other times I'll have left it for a few hours from 100% and find it in a completely normal state, only having drained a little bit (3% - 5% maybe). I've tried using minimum applications, even removing winterboard, but this doesn't fix it. So I'm simply going to restore it to retail until I can find a solution. Any advice/solution would be greatly appreciated.
