Phone Turns On and Off Repeatedly

When your phone continually restarts, it can be more than just a nuisance—it might indicate a more serious issue. Understanding the causes and solutions is key to resolving this problem effectively.

Common Causes and Solutions:

  1. Restart Your Phone:
    • A simple restart can sometimes resolve conflicts between phone components. Hold down the power button for 8-10 seconds or until the device reboots​​.
  2. Battery Issues:
    • A flat battery can cause your phone to shut off and restart. Charge your phone with its original charger and check if the problem persists. If the battery can’t hold a charge, consider replacing it​​.
  3. Scheduled Power On/Off Settings:
    • Check if your phone is set to turn off/on automatically. Disable or adjust these settings if active​​.
  4. Uninstall Suspicious Apps:
    • Boot your phone in safe mode to determine if an app is causing the issue. Remove any suspicious apps and restart your phone​​.
  5. Declutter Phone’s Memory:
    • Free up memory and storage by deleting rarely used apps and extensive files, then restart your phone​​.
  6. Check the Power Button:
    • Ensure the power button is not stuck or faulty, as this can trigger continuous restarting​​.
  7. System Updates:
    • Install the latest updates for your phone’s software to fix potential bugs and system instability​​.
  8. Professional Help:
    • If hardware issues are suspected and all other fixes fail, seek professional help, especially if your phone is still under warranty​​.

Additional Steps for iPhones:

  1. iOS Update:
    • Outdated iOS can cause performance issues. Update your iPhone to the latest version via Settings > General > Software Update​​.
  2. Update and Uninstall Apps:
    • Update important apps and uninstall unused ones to avoid compatibility issues​​.
  3. Third-Party Repair Apps:
    • Consider using third-party apps like Tenorshare ReiBoot for fixing reboot loops without data loss​​.
  4. Factory Reset:
    • Resetting your iPhone’s settings can resolve deeper software issues without losing data​​.
  5. Drain and Recharge Battery:
    • Completely draining and recharging your iPhone’s battery can recalibrate it and resolve turning on/off issues​​.
  6. DFU Mode:
    • As a last resort, switch your iPhone to DFU (Device Firmware Update) Mode for a clean iOS installation. Note that this will erase all data​​.


Fixing a phone that keeps turning on and off involves a systematic approach, from simple restarts to more complex software updates and, in some cases, professional repair. By following these tips, you should be able to diagnose and fix the issue effectively.
