With the recent release of iOS 14.5 beta 6, Apple has introduced a new battery recalibration tool for iPhone users. According to 9to5Mac, the tool will show up for users who have experienced reduced peak battery performance.
While the battery recalibration tool has not yet made its way to a general iOS release, the iOS 14.5 beta 6 source code seems to reveal a link to a support article on Apple’s website that is now live and provides more details about this new feature.
Apple notes the new battery recalibration tool will help users to “address inaccurate estimates of battery health reporting for some users.” The feature is, however, currently only compatible with iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max.
iOS 14.5, coming later this spring, includes an update where the battery health reporting system will recalibrate maximum battery capacity and peak performance capability on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users.
Symptoms of this bug include unexpected battery drain behavior or, in a small number of instances, reduced peak performance capability. This inaccurate battery health reporting does not reflect an issue with actual battery health.
iPhone’s battery recalibration will occur during regular recharge cycles and the process may take a few weeks to complete. When the recalibration is finished, maximum capacity percentage and peak performance capability data will be updated in the Settings app.
