Checking Battery Integrity
Step 1. From the iPhone application menu, go to "Settings" and touch "Battery".
Open the battery settings
Step 2. Go to "Battery Health" and check the item "Maximum Capacity".
Checking battery capacity
If it's 100%, it means your iPhone battery is perfect. The lower the percentage, the greater the wear. If the battery is heavily worn, iOS will automatically reduce processor performance to prevent unexpected shutdowns. However, you will have the option to disable this feature.
