Hi. I've searched the forums and haven't really seen too much about this exact issue (have seen other battery complaints). My battery was great before IOS7. But now it seems to drain faster (fine, I'll deal). But my battery will be to 30% or so and I'll use it for a minute and it'll jump to 10% and then turn off. When I go to plug it in, the phone comes right back on and is at 40%. I've already tried a restore and a bunch of other troubleshooting ideas. I'm going to the Apple Store today but I was just wondering if this happened to anyone else?
