Why does my iPhone keep restarting?
If your iPhone keeps restarting, it could be due to a few issues, ranging from software glitches to battery problems:
- A recent update. New software updates can sometimes bring bugs that disrupt phone stability.
- Software glitches. Minor app or operating system bugs may cause your iPhone to crash and restart. Regularly updating your device can help fix these glitches and keep your phone running smoothly.
- Battery health. An aging battery can struggle to provide stable power, causing unexpected restarts. Keeping an eye on your battery's health and replacing it when necessary can prevent these issues.
- Overheating. iPhones automatically shut down to prevent damage from overheating. To manage this risk, keep your phone out of the sun and avoid using intensive applications in hot conditions.
- Hardware issues. Severe issues like faulty hardware can also lead to your iPhone constantly restarting. These issues require a professional repair to diagnose and fix the underlying problem.
