If you're an iPhone user, you may have experienced the frustrating issue of random restarts. Your phone may turn off unexpectedly, and when you turn it back on, it boots up as if it were brand new. This problem may appear in almost all the models, including 6, 6s, 7, 8, X, 11, 12, 13, 14, 15, 16, and its high-end pro and pro max models.

Usually, this problem is caused for a variety of factors. In older iPhones, random restarts happen for performance degradation and memory issues. But new devices are more likely triggered by software-related issues, including software glitches, outdated software, hardware problems, battery issues, and malicious apps. In several ways, you can encounter iPhone's random restart problem.

Why Does My iPhone Keep Restarting?

Understanding what is causing your iPhone for a random restart is necessary before following the troubleshooting steps. One of the biggest reasons is outdated software. It can also occur for various factors, such as:

  1. Software glitches: Bugs or errors in the iOS software can cause your iPhone to malfunction and restart unexpectedly.
  2. Hardware problems: Issues with internal components, such as a faulty battery or damaged charging port, can cause your iPhone to shut down unexpectedly, resulting in random restarts.
  3. Battery issues: If the battery is old, worn out, or damaged, it may not be able to hold a charge properly, which can cause the iPhone to shut down unexpectedly and restart.
  4. Overheating: When an iPhone overheats, it can trigger a safety mechanism that shuts it down and restarts it.
  5. Malware or viruses: Although rare, malware can cause your iPhone to malfunction and restart unexpectedly. Installing security updates and downloading apps from trusted sources is important to avoid this issue.
  6. Memory issues: Some apps may use too much memory or cause memory leaks, leading to random restarts.
  7. Malicious apps: Although rare, some apps may contain malware or viruses that can cause your iPhone to malfunction and restart unexpectedly.
