How to stop your iPhone from restarting
If your iPhone keeps restarting, it’s usually down to a software fault, a faulty app or a worn battery. Start by updating iOS, doing a force restart and deleting apps that crash. If that doesn’t help, you can reset all settings or restore the phone. If it keeps restarting after that, it’s typically the battery or another hardware fault.

Why does my iPhone restart on its own?
- Software fault: A bug in iOS or an update that was interrupted.
- Faulty apps: An app that crashes can take the whole system down with it.
- Worn battery: An old battery can’t deliver steady power, so the phone shuts off and restarts.
- Hardware fault: A drop or water damage can damage the charging port, the battery or the logic board.
How to stop your iPhone from restarting
1. Check for software updates
Go to Settings > General > Software Update and install the latest version of iOS. You can see which version is the latest on Apple’s website.
2. Do a force restart
A force restart can clear temporary glitches. On iPhone 8 and later: quickly press volume up, then volume down, and hold the side button until the Apple logo appears. For other models, see my iPhone won’t turn on.
3. Delete problem apps
If the phone restarts when you use a particular app, update it or delete it. If the problem started after you installed a new app, start there.
4. Reset all settings
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. It doesn’t delete your data, but it puts your settings back to the defaults.
5. Restore your iPhone via Finder or iTunes
If nothing else works, you can restore the phone via Finder (Mac) or iTunes (Windows). Make a backup first – a restore erases everything on the phone.

Frequently asked questions
Why does my iPhone restart when the battery is low?
That points to a worn battery that can’t deliver enough power. Check the battery health under Settings > Battery.
What is a restart loop?
It’s when your iPhone restarts again and again and never gets past the Apple logo. Try a force restart, and if that fails, an update via a computer.
Will I lose my data if I reset all settings?
No. Reset All Settings keeps your photos, apps and data. Only a restore erases everything.
