Some time ago, Apple just released the official version of iOS 16.2, and this update also adds many new features. For example, Apple launched the "Infinity" app, and also added Apple Music singing, lock screen improvements and other functions for the iPhone, and Apple also fixed some bugs.
Although Apple fixed some bugs in the official version of iOS 16.2, Apple still has some hidden vulnerabilities, such as the power display problem of the Air Pods charging case.
Recently, many users have reported that after upgrading their iPhones to the official version of iOS 16.2, when the iPhone is connected to AirPods, the power of the charging case is displayed as 0, even if the battery is fully charged.
In addition to this bug, many users have recently reported on Apple's official forum that their AirPods Pro 2 charging case has inexplicably lost power. For example, without use, the charging case will lose about 20%-25% of the power in a day.
In addition, some users said that their AirPods Pro 2 charging case was placed for 32 hours after being fully charged, and the power was only 52% left without use.
The problems that occur are basically devices upgraded to 5B58 firmware, although Apple has not responded, but I estimate that this should be a firmware problem.
