With the iOS update to version 14.5 , Apple users who have an iPhone 11 are in luck. From now on, a recalibration can be carried out to determine the maximum capacity and peak performance capacity of our mobile battery. That is, we will be able to further increase the autonomy of our battery
As explained by Apple on its support page, with this update this function is implemented. Even after recalibration is complete , the percentage of maximum capacity and the peak performance capacity are updated. The recalibration message that appeared to us will disappear, indicating that this process has ended.
How to recalibrate
This battery recalibration will only appear on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. Since an error was causing the system that is responsible for reporting on the status of the battery to give erroneous data and caused various failures. For example, a reduction in the peak performance capacity of the battery and also an unexpected battery discharge behavior, resulting in autonomy problems and sudden changes in battery values . That is why iOS 14.5 has been dedicated to recalibration.
Although, Apple has ensured the percentage of the maximum capacity of the battery will not change, although the peak performance of our mobile will do. In order to access this recalibration, you will have to enter Settings > Battery > Battery health . Once inside, one of the following messages will appear:
- “The battery health information system is recalibrating the maximum capacity and peak performance capacity of the battery. This process may take a few weeks.” This message will mean that recalibration is in progress .
- “The battery health information system is recalibrating the maximum capacity and peak performance capacity of the battery. This process may take a few weeks. At this time, no repair of any kind can be recommended.” If this message has appeared, it will mean the same as in the previous case. Although with the difference that no type of repair can be recommended until this process is finished, which can take weeks.
- “The battery health information system could not be recalibrated. An Apple Authorized Service Provider can replace the battery free of charge to restore maximum performance and capacity.” In the latter case, the system could not be recalibrated , but the battery can still be used. Although they give us the option to change it if we go to an Apple service provider, where they will replace the battery completely free of charge.
