Apple released beta 6 for iOS 14.5 to developers a few weeks ago. The update included a new battery recalibration tool that aims to recalibrate maximum battery capacity and peak performance capability for iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max to address inaccurate estimates of battery health reporting for some users.
The recalibration process takes weeks to process as it requires regular charge cycles from using your phone. Now that two weeks have passed since the beta was released, some users are beginning to see a recalibrated estimate of their iPhones’ Maximum Battery capacity.

As reported by The 8-Bit, Twitter user guilhermelage91 stating that his battery health keeps increasing on his iPhone 11 Pro. “It went to 86% after finishing recalibration and now after installing iOS 14.5 Beta 8 just went to 87%.” He is not the only one, several other users took to Reddit to post their battery recalibration results. For some users, the process improved the Maximum Capacity percentage while for others, it has deteriorated.
To recalibrate iPhone 11’s battery health reporting system on iOS 14.5, go to Settings > Battery > Battery Health. You will see this message: “Your battery health reporting system is recalibrating Maximum Capacity and Peak Performance Capability. This process may take a few weeks. Learn more…”
Once recalibration is started, it might take a few weeks for it to resolve the issue through many charge cycles. As Apple explains in a support document, “Maximum battery capacity is determined using a set of algorithms and measurements taken during use. Over time, these algorithms might be updated to provide the best estimate of maximum battery capacity.”
However, if the issue is still not fixed, and users see a battery service message, Apple says that an Apple Authorized Service Provider will replace the battery free of charge.
The Battery Health Recalibration tool is expected to release alongside the iOS 14.5 update which is currently only available for developers and public beta testers in beta capacity.
