Check Your Battery Health
To view your phone’s Battery Health, follow these steps:
. Tap Settings
. Tap Battery
. Tap Battery Health
The Maximum Capacity menu shows the total charge capacity your battery can hold, the higher the better.
If your Maximum Capacity is very low, that may be a sign of a problem with the battery.
The Peak Performance Capability menu tells you whether the performance of your iPhone has been automatically decreased due to issues with the battery.
If you see anything other than Peak Performance Capability, that may be a sign that your battery has issues.
The Battery Health section will also tell you if your battery is at a point where it needs to be replaced.
Restore iPhone from Backup with DFU
If your iPhone is still shutting down unexpectedly, you’re going to need to try a bigger step: a DFU restore of your iPhone. DFU which stands for Disk Firmware Update, creates a fresh installation of all software on the iPhone, not just the operating system, which is a more comprehensive kind of reset.
To do this, you’re going to need a computer with iTunes installed on it that you can sync your iPhone to. Once you’ve got that, follow these steps:
a. Connect your iPhone to the computer via USB.
b. In iTunes, make a backup of your iPhone by clicking Back Up Now in the main iTunes window.
c. With that done, you need to put your iPhone into DFU Mode.
How you do this depends on the model you have:
1. For iPhone 8 and iPhone X, quickly press and release the volume up button, then the volume down button, then press and hold the Side button. Keep holding the Side button and, when the screen turns black, press and hold volume down.After 5 seconds, let go of the Side button, but keep pressing volume down. When your iPhone appears in iTunes, let go of the button.
2. For iPhone 7, press and hold the on/off button and volume down button at the same time. When a window pops up in iTunes that says iTunes has detected an iPhone in recovery mode, let go of the volume down button. If the iPhone’s screen is black at this point, you’re in DFU Mode.
3. For all other models, the steps are the same as for the iPhone 7, except you hold down the on/off and Home buttons instead of the volume down button.
