Sina Digital News reported on the morning of December 7 that some users on Apple’s official developer forum and third-party forum Reddit said that iOS 14.2 will cause the problem of faster device battery consumption.
Discussion of the matter on Apple’s developer forum
Symptoms of this problem include rapid battery drain and longer charging times than usual. Some users report that their devices lose more than 50% of the power in less than 30 minutes, and that a sharp drop of approximately 5% is visible to the naked eye within a few minutes of normal use.
The problem seems to be related to the software, because multiple users have been in a normal state of battery life before the power loss, and the battery life suddenly increased after restarting the device.
Reddit’s post on iOS 14.2 is better
The affected iPhones seem to be older models, such as iPhone XS, iPhone 7, iPhone 6S and the first generation iPhone SE. The 2018 iPad Pro running iPadOS 14.2 also seems to be affected.
Currently, there are no new posts indicating that the battery problem has been fixed in iOS 14.2.1.
The third developer and public beta version of iOS 14.3 and iPadOS 14.3 has been released, so Apple may resolve this issue in this update. It is said that the third major update of iOS 14 will bring support for the Apple ProRAW format and improvements to the family, health and weather.
Users of old devices can temporarily stop the iOS 14.2 update until this problem is resolved.
