Have you ever wondered why your iPhone unexpectedly restarted in the middle of your everyday routine? 

In this article, we will explore reasons for iPhone restarting randomly and provide solutions to fix this problem. 

Why does Your iPhone Randomly Restart?

There is doubt about the stability of your device due to the phenomenon of your iPhone restarting on its own. Software bugs, memory restrictions, or overheating are frequent offenders. Sometimes, a problematic app or a future software update might cause similar behavior.

In addition, these restarts could be caused by hardware problems or battery anomalies. Investigating these potential causes can assist in identifying the precise causes of your iPhone’s erratic restarts, enabling the development of efficient solutions to bring back its seamless operation.

How to Stop iPhone from Restarting Itself? 

By carefully following these instructions, you can improve your comprehension of why your iPhone restarts and acquire more control over its stability, resulting in a more pleasurable digital experience.

1. Software Updates and App Management

 It’s important to keep the operating system on your iPhone up to date. Glitches may result from outdated software. In addition, update any troublesome apps that might generate issues or delete them. To make sure you have the most recent version, 

  • Go to Settings 
  • Then General 
  • Software Update.

2. Clear Cache and Data

Cache data can build up over time and result in irregular behavior. Uninstall the problematic app and reinstall it to solve any app-specific problems. 

  • Go to Settings 
  • Then Safari 
  • Clear History and Website Data to clear Safari’s cache

3. Inspect the Battery

A failing battery can lead to unforeseen restarts. Consider purchasing an Apple battery replacement if necessary. To check the health of your battery, 

  • Navigate to Settings. 
  • Then Battery 
  • Battery Health.

4. Reset All Settings

Resetting settings can fix configuration issues. This will reset all settings to their default state without erasing your data. 

  • Go to Settings 
  • Then General 
  • Reset all settings.

5. Examine Recent Installations or Changes

Consider any recent installations or changes that might be connected to the restarts. Remove recently added apps to check whether the issue continues.

6. Device Firmware Update (DFU) Restore

As a final option, carry out a DFU restore. To do a DFU restoration, connect your iPhone to a computer, launch iTunes (or Finder on macOS Catalina or later), and then follow the on-screen directions. To avoid losing anything, make sure you have a backup.

7. Contact Apple Support

If none of the above-mentioned fixes work, it’s time to seek out expert assistance. To identify and fix the problem, speak with Apple Support or stop by an Apple Store.

8. Consider Hardware Issues

If your iPhone’s restarts continue after attempting software solutions, there might be underlying hardware problems. Professional evaluation and repair may be required in such circumstances.

9. Prevent Overheating

High temperatures can lead to restarts. Ensure your iPhone isn’t left in the sun for too long, and stay away from hot places when using power-hungry apps.

10. Manage Multitasking

By shutting down inactive apps and controlling background tasks, you may lessen the load on your iPhone’s resources and possibly avoid unplanned restarts.

Why did Your iPhone Randomly Restart while Charging?

There are several causes for your iPhone to restart unexpectedly while it is charging, most frequently a mix of software and hardware problems. Several possible explanations include:

1. Overheating

Charging your phone produces heat, and if the device overheats because of excessive charging or a charger that isn’t suitable, built-in safety systems may trigger a restart to prevent damage.

2. Charging Cable or Adapter Issues

Defective cables or adapters might result in erratic power delivery, forcing the phone to restart as it tries to balance its power source.

3. Background Apps

During charging, when power consumption is high, intensive background processes or troublesome apps that use too much power might cause instability and restarts.

4. Insufficient Free Space

A phone’s capacity to carry out important functions while charging may be hampered by a lack of available storage, which may result in a restart.

5. Third-Party Accessories

Using cables, adapters, or other accessories not approved by the manufacturer could cause compatibility problems and restarts.

To solve this problem:

  • Make sure to use a genuine charger and cable.
  • While charging, keep your smartphone in a well-ventilated space.
  • Get the most recent version of your software.
  • Check the battery’s condition and, if required, consider replacing it.
  • Manage multitasking and remove unneeded background applications.
  • If the situation continues, get assistance from Apple Support or go to an Apple Store, as there might be underlying hardware problems.


A complicated interaction of software bugs, hardware quirks, and charging dynamics plays crucial roles in the complex world of iPhone restarts.

You can find the reasons and solutions for these unforeseen restarts by investigating software upgrades, battery health, and the best charging techniques, resulting in a smoother and more reliable digital experience.
