If your iPhone keeps shutting down, there are several reasons for this, including the battery, faulty apps, or damage from water.
How To Fix iPhone Keeps Shutting Down Problem
Hard reset
A hard reset works by resetting the operating system and iPhone’s memory without data loss on your part. If the issue is an app that drains your battery, then a hard reset can fix it.
To do this:
- Depending on your iPhone model, click the Home and on/off/Side button (older models) or hold down the volume down and side button (iPhone 7), or if you have an iPhone 8 or X, click and release volume up and volume down buttons and then click and hold the Side button.
- Hold the buttons till the screen is dark and the Apple logo is displayed
- Release the buttons and allow the phone to start normally
Update operating system
If your iPhone keeps shutting down, the issue could be its OS. If you tried a hard reset and it still shuts off randomly, and your iOS version is earlier than 11.2, update to the latest one. To do this:
- Tap Settings>Notifications
- Now tap every app you see listed and move its Allow Notifications slider to off
- Update the OS. After the phone restarts, repeat the two steps and turn on notifications for each app whose notifications you turned off in the previous step
Battery Health check
For iOS 11.3 or later, Battery Health feature shows the maximum charging capacity and strength of your battery, and how they affect its performance. To do this:
- Tap Settings>Battery>Battery Health
- Now tap Maximum Capacity to see the maximum charge your battery can hold. A higher figure is better. If it is low, the battery may have an issue
- Peak Performance Capability tells if your battery is affecting the performance of your iPhone
Battery Health feature also tells you if your battery needs a replacement.
Use DFU to restore iPhone from Backup
DFU (Disk Firmware Update) creates fresh software installations on your iPhone, not just for the OS, and requires a computer with iTunes to sync your iPhone first. Once synced, take the steps below:
- Connect your iPhone to the computer
- Go to iTunes and click Back Up Now to back up your iPhone
- Put your iPhone in DFU mode depending on your model
- Restore your iPhone from the backup
If all else fails, contact Apple experts or support for a battery replacement.
