iPhone 5 keeps restarting

So this morning, my phone has started to act weird. Mail won't open properly, it opens and then force quits.


Now every few minutes my handset is restarting itself. I've not installed any new apps as of late and this has only been happening since this morning. I've also noticed that my phone will come up with 'No SIM Installed'. It's done this a couple of times since yesterday morning.


Any ideas anyone? Thanks!

I am having the same issue with my iPhone 5. I have been playing this game called Pocket Planes and I went to open it last night and my whole phone crashed! Im not sure if the app had anything to do with it or not. It keeps on booting up and then starting over.. never actually fully opening up. I have not dropped it or anything. The sprint store opens up at 10:00 am and I will be there trying see whats going on.

I have Pocket Planes on my iPad 3 and that's fine. The latest app I've downloaded/played is Hay Day but I had that a few days before problems started. I've also noticed that this constant restarting had drained my battery no end. Usually around this time i'm at 50-60% but I'm on less than 20%


After having a look at the Apple website, they said do an iOS restore. So going to do that once I'm home to see if this sorts things.

figured out how to solve the problem.

First restore your iphone 5 in dfu mode. after you do this you would realize it still restarts. dont be worried, shutdown the iphone for 24 hours and do not restore from backup after switching it on. you would need to treat it as a new iphone. Hope it works for u guys cuz it worked for me twice. let me know if it works.
