When an iPhone shuts down unexpectedly, many people worry about a faulty power IC. However, this problem could be due to software conflicts or an iOS version issue.
How to fix an iPhone that keeps shutting down.
1. Reasons why iPhones shut down unexpectedly.
- Software error : Due to app conflicts, a minor bug in an iOS update, or a false battery reading.
- Hardware failure : Due to device overheating, battery overload, power IC, or display cable issues.
2. Drain the battery completely to fix an iPhone that keeps shutting down.
The most common cause is an inaccurate battery capacity reading. If you notice the battery draining slowly but the phone shuts down when it's at 10-30%, the battery may be faulty.
Using 3G or 4G for gaming also drains the battery quickly. To fix this, completely discharge the battery by playing games, recording videos, taking photos, then turn off the phone and recharge it.
Use genuine Apple chargers and cables to avoid errors. Charge for about 3 hours, then unplug, turn on the device, and check if the power off issue has been resolved.
