Apple has published a new support document detailing the recalibration of the battery status introduced in iOS 14.5. According to the company, this recalibration will address the battery health reporting system found in the iPhone 11 series, specifically addressing “inaccurate battery health estimates” that some users have reported.
Lithium-ion batteries – the type found in personal devices – undergo chemical aging and, over time, lessen the charge they can contain. When this happens, the device needs to be recharged more frequently and performance can be accelerated to accommodate the reduction in peak power capabilities.
IOS 11.3 brought a Battery Health menu to the iPhone 6 and newer that makes it easier for users to track the battery status of their phones, particularly their maximum charge capacity and maximum performance.
In its new support document, Apple explains that iOS 14.5 – which will be available to general users starting this spring – will recalibrate the maximum performance capacity and maximum battery capacity of iPhone 11 series phones. problem that this recalibration will address, Apple says:
Symptoms of this bug include unexpected battery drain behavior or, in a small number of cases, reduced peak performance capability. This inaccurate battery status report does not reflect an issue with the actual battery status.
Apple notes that the recalibration process may take a few weeks and that users will see a message in the Battery Health menu while it is taking place. Once completed, users will see updated peak performance and maximum battery capacity and the recalibration message will disappear. Likewise, the company says that some users may experience an unsuccessful recalibration, in which case the company will replace the battery for free.
