David & David explain how to fix the problem when your iPhone keeps restarting. The first thing to do when your iPhone is stuck in a restart loop is to hard reset it. This will force your your iPhone to abruptly turn off and back on.

Once your iPhone has turned on again, back it up, then check for an iOS update.

Sometimes iPhones keep restarting due to a specific app. You can check for troublesome apps in the Analytics & Improvements section of your iPhone's Privacy Settings. Just tap "Analytics Data" and look to see if one app is listed over and over again.

A poor connection between your iPhone and your wireless carrier can also cause restart loops. Try ejecting and reinserting your iPhone's SIM card to see if that fixes the problem.

If your iPhone still keeps restarting, try resetting all of its settings. Everything — including your Wi-Fi passwords, Bluetooth devices, and wallpaper — in the Settings app gets reset to factory defaults.

The final step you can take to completely rule out a software problem is a DFU (Device Firmware Update) restore. Every line of code on your iPhone gets erased and reloaded. It'll be as if you were taking your iPhone out of the box for the very first time.
