Main Causes of Your iPhone 12 Keeps Restarting and How to Fix It

There’s no doubt that iPhone users love their devices, but sometimes they may experience an issue where their phone keeps restarting on its own. This can be quite frustrating, but thankfully, there are several solutions to this problem.

The main causes for an iPhone constantly restarting are due to either software glitches or hardware issues, such as a bad battery connector or a defective component. To tackle the software-related issues, users can try force restarting their iPhone and updating all apps on the device.

Additionally, restoring the iPhone via recovery mode or putting it in DFU mode may help.

If these methods don’t work, consulting an authorized Apple service center is recommended to check for hardware problems. With these tips, iPhone users can enjoy a smooth experience with their devices once again. 

The 4 Causes of iPhone 12 Pro or Mini keeps restarting

  1. Interrupted software update: An iPhone 12 may get stuck in a continuous reboot loop if a software update is interrupted. This can happen due to network issues or other interruptions during the update process.
  2. Malware or faulty apps: While Apple’s strict app vetting process ensures most apps on the App Store are safe, some malicious apps may still slip through. Additionally, using free public Wi-Fi can also increase the risk of malware infection, causing your iPhone 12 to frequently restart.
  3. Insufficient storage: Overflowing storage can cause an iPhone 12 to get stuck in a boot loop. Clearing up storage space by deleting unnecessary files and apps can help resolve this issue.
  4. Hardware problems: Drop damage, water damage, or aging batteries can lead to hardware failure, causing an iPhone 12 to restart spontaneously. In such cases, it is recommended to consult an authorized service provider for necessary repairs.
