Phone Keeps Restarting Randomly? 10 Fixes That Actually Work

 

Introduction

If your phone keeps restarting randomly, freezing, or getting stuck in a boot loop, it can be very frustrating. This issue is common on both Android and iPhone devices and is usually caused by software bugs, faulty apps, overheating, or battery problems.

The good news is that in most cases, you can fix it yourself without going to a repair shop. Below are 10 proven solutions that actually work in 2026.

1. Check for overheating

Overheating is one of the top reasons for random restarts. Phones automatically reboot to protect internal components.

Fix:

  • Remove phone case while charging
  • Avoid heavy gaming for long time
  • Keep phone in a cool place

2. Uninstall recent apps

A recently installed app may be crashing the system.

Fix:

  • Delete apps installed before the issue started
  • Avoid unknown APK files
  • Restart your phone after uninstalling

3. Update your software

Old software versions often contain bugs that cause restarts.

Fix:

  • Go to Settings → Software Update
  • Install the latest version available

4. Free up storage space

Low storage can make your phone unstable.

Fix:

  • Delete unused apps and videos
  • Clear cache files
  • Keep at least 10–15% free space

5. Check battery health

A weak battery can cause sudden shutdowns and restarts.

Fix:

  • Check battery health in settings
  • Replace battery if health is below 80%

6. Remove SIM and SD card

Sometimes a damaged SIM or SD card causes system crashes.

Fix:

  • Power off your phone
  • Remove SIM and SD card
  • Restart device

7. Boot in Safe Mode (Android)

Safe Mode helps detect if an app is causing the issue.

Fix:

  • Hold power button
  • Long press “Power Off” → Safe Mode
  • If problem stops → uninstall recent apps

8. Clear cache partition (Android)

Corrupted cache can cause random reboots.

Fix:

  • Enter recovery mode
  • Select “Wipe cache partition”

9. Factory reset (last option)

If nothing works, reset your phone.

Important: Backup your data first.

Fix:

  • Settings → Reset → Factory Reset

10. Check for hardware problems

If the issue continues after reset, it is likely hardware-related.

Possible causes:

  • Battery failure
  • Motherboard issue
  • Water damage

👉 In this case, visit a repair technician.

Conclusion

Random phone restarts are usually caused by software or battery issues and can often be fixed with simple steps. If the problem continues after all fixes, it is likely a hardware fault.
