Why Does an iPhone Keep Restarting?

1.1 Software-Related Causes

  • Buggy iOS Updates: Sometimes new updates cause instability.
  • Corrupt Apps: Third-party apps may conflict with system processes.
  • Jailbreaking Issues: Modified iPhones are more vulnerable to boot loops.
  • Low Storage: Running out of storage may cause critical system crashes.

1.2 Hardware-Related Causes

  • Battery Problems: A failing or swollen battery can trigger shutdowns.
  • Loose Connections: Damaged logic boards or connectors interrupt power flow.
  • Overheating: Excessive heat forces iPhones to restart as protection.
  • Water Damage: Even small amounts of liquid can corrode internal parts.

1.3 Environmental Triggers

  • Extreme temperatures (cold or hot)
  • Using uncertified charging cables or adapters
  • Power surges during charging

Quick Fixes You Can Try at Home

2.1 Force Restart the iPhone

A force restart can clear temporary glitches.

  • iPhone 8 or later: Press and release volume up, then volume down, then hold power until Apple logo appears.
  • iPhone 7: Hold volume down + power button together until restart.
  • iPhone 6s or earlier: Hold home + power button until restart.

2.2 Update iOS

Keeping your iPhone up to date often fixes restart bugs. Go to Settings > General > Software Update.

2.3 Delete Problematic Apps

If the issue started after installing an app, uninstall it. Apps with poor coding can cause restart loops.

2.4 Check Storage Space

Low storage makes iOS unstable. Delete unused apps, clear cache, or move files to iCloud.

2.5 Reset All Settings

Go to Settings > General > Reset > Reset All Settings. This won’t erase data but resets Wi-Fi, Bluetooth, and display settings.

2.6 Remove SIM Card

A faulty SIM or network issue may trigger restarts. Remove and reinsert the SIM to test.

Advanced Fixes

3.1 DFU Mode Restore

Device Firmware Update (DFU) mode reloads iOS from scratch. This is often the ultimate software fix but erases all data. Always back up before attempting.

3.2 Battery Replacement

If the battery is degraded, replacement is the best solution. Signs of battery-related restart issues include sudden shutdowns at 20–30% charge or visible swelling.

3.3 Logic Board Repair

If physical damage or water exposure caused the problem, logic board repair may be required.
