How do I fix an iPhone that keeps turning off?
Lately, I have been experiencing a frustrating issue with my iPhone where it unexpectedly shuts down for no apparent reason. It happens randomly throughout the day, disrupting my normal use and causing me to miss important calls and notifications. Sometimes, the phone won’t turn back on until I plug it into a charger, even though the battery still has plenty of life left. This issue persists regardless of whether the phone is fully charged or not, and it doesn’t matter if I’m using a specific app or just have it sitting idle. I’ve tried some basic troubleshooting like restarting the device and making sure the software is up to date, but the problem continues. I’m at my wit’s end and need to understand why this is happening and what I can do to fix it.

I once faced a similar issue and discovered it was due to internal hardware damage. The solution in my case required contacting Apple Support. They ran diagnostics and found a hardware malfunction, leading to the replacement of an affected component. If none of the standard troubleshooting methods work, consider reaching out to professional support to check for hardware problems.
What helped me resolve this was recalibrating the battery. I let the battery drain completely until the phone turned off by itself. Then, I charged it non-stop to 100% without interrupting the charge cycle. I repeated this process a couple of times and noticed a significant improvement. Fixing deeply discharged battery issues can sometimes mitigate such random shut-offs.
Put your iPhone in DFU mode. This is a deeper restore mode than a standard factory reset. Connect your iPhone to a computer, open iTunes, and follow these steps:
1. Quickly press and release the volume up button.
2. Quickly press and release the volume down button.
3. Hold the side button until the screen goes black, then hold down the volume down button while continuing to hold the side button.
4. After about 5 seconds, release the side button but keep holding the volume down button until your iPhone appears in iTunes.
5. Follow iTunes instructions to restore the iPhone.
This process can resolve deeply embedded software issues causing the phone to malfunction.
- Check Battery Health: Go to Settings > Battery > Battery Health. If your battery capacity is below 80%, you might need a replacement.
- Update iOS: Ensure your iPhone is running the latest software. Check for updates under Settings > General > Software Update.
- Reset All Settings: Navigate to Settings > General > Reset > Reset All Settings. This will not erase your data but will reset your device’s configuration settings.
- Check for Faulty Apps: Sometimes, apps can cause continuous crashes. Delete any recently installed apps that might be causing issues.
- Restore from Backup: If the problem persists, backup your iPhone and restore it through iTunes or iCloud. This often fixes software-related issues.
- Disable Background App Refresh: Go to Settings > General > Background App Refresh and turn it off. This reduces background activity, conserving battery and reducing system load.
- Keep Your iPhone Cool: iPhones can shut off if they overheat. Avoid direct sunlight or hot environments for extended periods.
- Manage App Usage: Some apps are resource-heavy. Limit or monitor usage of apps that tend to be high on performance requirements to prevent overheating and battery drain.
- Turn Off Bluetooth: Disable Bluetooth when not in use by pulling down the Control Center. Persistent Bluetooth use can cause power management issues.
- Use Only Original Accessories: Sometimes third-party cables or chargers cause erratic charging behavior leading to unexpected shutdowns. Stick to Apple-certified accessories for stable charging.
Check for a software bug. My iPhone had the same issue after an iOS update, and Apple released a follow-up patch to fix it. Go to Settings > General > Software Update and download available updates. If an update is available, install it, as it might contain fixes for issues causing your phone to turn off.
