Unfortunately, it is no longer under warranty
I've tried powering off rather than just letting it go to sleep. If the battery falls low enough to die - say I had 10% left, and ended up forgetting to charge it for a week or what not - then still, it will go to the "restoring" screen.
It doesn't matter if I've just powered on to realize its dead, or if I plug it in first - when the battery is able to turn it on, it's lost everything and I have to reload everything. It's getting really rather annoying.
Any ideas??
