wasnt sure whether to put this here on under iphone. My iPhone battery percentage indicator is off. There is about ten percent worth of charge above 100%. ive attempted to correct this by calibrating the battery but it seems to revert shortly after. I was going to attempt a clean install of iOS without erasing my phone.. I think this is done through dfu mode or something? If anyone has clear instructions for how to do this I'd appreciate it! I'm wondering is there are any other suggestions/fixes out there?
