iPhone won't turn on - unable to start

What to do if your iPhone won't turn on?

Your iPhone won't turn on or start? There can be various reasons for this, such as a dead or defective battery, software issues, or hardware defects.

In this post, you'll find possible causes and tips on how to solve the problem.

Possible Causes:

1. The battery is empty or defective

   • Maybe your iPhone has run out of power, or the battery is damaged.

2. Software error

   • A system crash or a failed update might prevent the iPhone from starting.

3. Hardware issues

   • Damage to the screen, charging port, or motherboard could be the reason.

4. External influences

   • Physical damage from drops or liquids could affect your iPhone.

Suggested solutions:

1. Basic measures

• Check charging status
  Connect your iPhone to a charger for at least 30 minutes. Use an original or certified Apple charger.

  • Test the charger and cable with another device to ensure they are working.
  • Check the Lightning port for dirt or foreign objects and carefully clean it if necessary.

• Forced restart (Hard Reset)
  Try to get your iPhone running again by restarting it:

  • iPhone 8 or newer: Quickly press the volume up button, then the volume down button, and then hold the side button until the Apple logo appears.
  • Older models: Hold the home button and the standby button simultaneously until the Apple logo appears.

2. Solve software issues

• DFU mode and recovery
  If a restart doesn't work, put your iPhone into DFU mode:

  • Connect your iPhone to a computer and open iTunes (or Finder if you're using macOS Catalina or later).
  • Start the recovery to reinstall the operating system.
    ⚠️ Warning: All data on the iPhone will be erased if you don't have a backup.

• Analyze error log
  If iTunes or Finder reports an error, it indicates a software issue that you may need professional help to resolve.

3. Identify hardware issues

• Check the screen
  If you notice vibrations or sounds but the screen remains black, it might be defective.

• Clean the charging port
  Carefully remove dirt or dust with a toothpick or brush.

• Seek professional help
  If none of the measures work, take your iPhone to a certified Apple technician or an authorized service center.

Prevention:

• Regular backups
  Regularly back up your data via iCloud or iTunes.
• Protection against damage
  Use a protective case and keep your iPhone away from water and extreme temperatures.
• Keep the system up-to-date
  Always install the latest iOS updates and avoid questionable apps.

Conclusion:

With the steps mentioned above, you can solve most problems yourself if your iPhone won't turn on. If the issue persists, professional repair is necessary.
