iPhone keeps restarting itself every 3 minutes I just got an iPhone 5 from my friend. It worked well and I decided to restore it to reset it. Yet it is now restarting itself every 3 minutes so I'm trying to do a factory restore. While letting it connected to my computer I pushed the top and menu button and went to iTunes. I get this message ~without any interaction~:


  iTunes is downloading the software for this phone and will restore




~It seems to be stuck, but it eventually restarted but~ it keeps restarting itself every 3 minutes.

Between restarts I can start to set the IPhone or even to use it a bit as everybody does if I was fast enough to set it.

Update

I think I achieved to reinstall the OS, but it keeps restarting itself every 3 minutes.
Since using iTunes to restore the iPhone can't solve this problem, the following method is worth a try:


Restore all settings on your iPhone.
Update all applications or remove potentially conflicting applications
Remove the SIM card from the iPhone and check if it stops restarting
Check and clean the charging port
If you restart when charging, please replace the iPhone battery
Finally, it is recommended to contact Apple officials for the best solution.
