Why Your Phone Keeps Restarting: Common Causes

Random restarts can happen for different reasons. Here are the most common culprits:

Faulty Apps or Software Bugs – Corrupt apps or outdated software can trigger reboot loops.
Battery or Power Issues – A failing battery or unstable power supply often causes restarts.
Overheating – If your phone gets too hot, it may shut down and restart as a safety measure.
Hardware Problems – Internal damage from drops or liquid exposure can disrupt system stability.
System Updates – Incomplete or corrupted updates may cause continuous reboots.

According to Apple Support, unexpected restarts are often linked to faulty system or app behavior, making diagnosis crucial.

Step-by-Step Fixes for iPhone & Android

1. Update Software & Apps
