Apple’s iOS 14.5 beta, which is currently being tested, introduces a new process to recalibrate battery health reports across iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max devices.
Apple is trying to fix the battery drain and reduce performance issues that affected some iPhone 11 devices by recalibrating their batteries in the next operating system update.
Symptoms of this error include unexpected battery draining behavior or, in some cases, reduced maximum performance capacity, and Apple says: Inaccurate reporting of battery condition does not reflect a problem with the actual battery health.
And as shown in Document Support, Apple says: The update calibrates maximum battery capacity and peak performance capacity across iPhone 11 lineup models to address inaccurate estimates of battery health reports some users have encountered.
The process occurs when you update iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max devices to the upcoming iOS 14.5.
And after installing the update, iPhone 11 users see a message in the battery health settings about the recalibration process.
It may take a few weeks for the battery health system to see how much remaining battery capacity and how much performance it can provide.
It doesn’t seem like users should notice much of a difference during the process, although a message appears in the Battery Health section of the settings menu explaining what is happening.
Recalibration of maximum capacity and maximum performance capacity occurs during regular charge cycles, and this process may take a few weeks, and the percentage of maximum capacity displayed will not change during recalibration.
When the recalibration is complete, the maximum capacity percentage and the maximum performance capacity information are updated, and if the recalibration indicates that the battery health has decreased significantly, users see a battery service message.
The maximum performance capacity may be updated, but this may not be noticeable by most users, and if a previous message about degraded battery is displayed, this message will be removed after the update to iOS 14.5.
The process is currently being tested in the latest version of the developer beta, and given that Apple has a support page for this process, there is a great opportunity to include it in the final version.
And the recalibration may not succeed in some cases, and the battery service message appears, and Apple says: It is replacing these affected batteries for free to restore full performance and capacity.
And if you are experiencing battery issues with your iPhone 11, this process may help mitigate them when iOS 14.5 is released.
It is not unusual for Apple to issue a document about changing the battery before the start of the replacement, and the company has been more transparent when it made changes to the iPhone’s power delivery system since the performance bottleneck of older iPhones was discovered to protect the battery.
