MacRumors reporters found this information on the Apple website. The company has promised that with the iOS 14.5 update, it will recalibrate the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max batteries.
The fact is that due to an error in the system, new devices began to incorrectly display the maximum battery capacity. In addition, some users have started to discharge their smartphones faster.
If after calibration the problems persist, a corresponding message will appear and you will have to contact the service center. In this case, the company promised to replace the battery free of charge.
