Iphone 5 not updating battery percentage. Now constantly restarting itself.
My iPhone 5 started two days ago just not updating the battery percentage. It stayed at the same percentage all day no matter how much I would use it and would only change if I would turn off the phone and turn it back on. I assumed this was starting because I had not done the update yet to my phone since I kept hearing mixed reviews about iOS7. I did the update and now my phone consantly restarts itself every couple of minutes. I cannot keep it on for more than 5 minutes. Even if I just let it sit without doing anything to it, it will restart itself. Each time it restarts the battery life shows as something different and I'm pretty sure its incorrect! I was annoyed at first and have tried doing everything I can to make this stop and now I'm just getting ****** that it's completely not working! I don't want to have to try to find the time to get to the apple store to have it looked at unless there is no way for me to fix this! I have never had ANY problems with any of my iPhones so I'm very upset that I upgraded to the 5 less than a year ago and have no issues with my iPhone 4. My boyfriend still uses my old iPhone 4 with no problems. I rarely do much on my phone so it's not like I/m on bad sites or downloading crap. I think I had just updated some of the apps that I've had on all my phones but that would be the only new thing that was done! Please someone HELP!
iPhone 5, iOS 7.0.4
