iPhone 12 battery Health

Hey I have a query. I have this message on my iPhone 12: Your battery health reporting system is recalibrating Maximum Capacity and Peak Performance Capability. This process may take a few weeks.


what does this mean?

Hello hanno94,


Thank you for posting in the Apple Support Communities. We're happy to answer your questions about the message you're seeing in Battery Health.


This message may appear on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max devices to more accurately report battery estimates. The details about this can be found at the web site below:

About recalibration of battery health reporting in iOS 14.5


Might you have an iPhone 11, instead? If not, your device may still be recalibrating the battery health reporting system as explained in the section "Battery recalibration messages" in the above article.


We hope this information is useful. Kind regards.
