Why Does My iPhone Keep Restarting Randomly?

If your iPhone keeps restarting by itself, it can be frustrating — and worrying. Known as a “boot loop” or random restart issue, this can have several causes. The good news? Most of them are fixable.

Common Causes of iPhone Restart Problems

There are a few key reasons your iPhone might be restarting on its own:

• Faulty or failing battery

• Corrupted software or iOS glitch

• Hardware fault with the charging port or logic board

• Recent app install causing system conflict

• Overheating or moisture exposure

If the problem appeared after an update or battery issue, that’s a strong clue.

What You Can Try Before a Repair

Before booking a repair, try these troubleshooting steps:

• Update to the latest version of iOS

• Check for recently installed apps and remove them

• Force restart your phone

• Reset settings (Settings > General > Transfer or Reset > Reset All Settings)

• Check battery health in settings

If your phone continues to restart randomly, it’s likely a hardware fault or deeper system issue.
