How to Recalibrate Your iPhone 11 or iPhone 11 Pro’s Battery
The new battery recalibration tool will only be available on the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max running iOS 14.5. Once you install the update, iOS will automatically start recalibrating the battery of your iPhone 11. You can confirm this by going to Settings -> Battery -> Battery Health. You should see an “Important Battery message” saying that your iPhone’s battery health reporting system is recalibrating. The process takes a few weeks to complete, so you won’t see any immediate benefits of this recalibration.
In case your iPhone 11’s battery is really in need of a replacement, you will get a message about the same after the recalibration process is complete.
