If you have an iPhone 11, this will come in handy.
With the release of iOS 14.5, Apple has introduced a new process for recalibrating the battery health reporting on the iPhone 11, 11 Pro, and 11 Pro Max.
The update recalibrate the maximum battery capacity as well as the peak performance capacity on the iPhone 11 models to address reported battery health inaccuracies that some users have encountered. In some cases, this bug has lead to unexpected battery drain behavior or in some cases, reduced peak performance capability. These issues should be fixed after installing the update.
Once you’ve updated your iPhone 11 to iOS 14.5 or later (Settings -> General -> Software Update), you’ll see a message in the Settings app under the Battery -> Battery Health section informing you of the recalibration process.
The process can take a few weeks to complete after installing the iOS 14.5 update given that recalibration of the battery’s maximum capacity and peak performance capability takes place over the course regular charge
It’s also worth bearing in mind that the displayed maximum capacity percentage won’t change during recalibration, and while peak performance capability might also be updated, it may not be noticeable.
Once the recalibration has completed will the information be regarded as accurate. If the recalibration indicates that battery health has indeed significantly declined, you’ll see a battery service message.
In some cases, your iPhone 11 battery’s recalibration may not be successful and a battery service message will pop up. In such cases, Apple has stated that the company will replace affected batteries free of charge to restore full performance and capacity to your device.
