iOS 14.6 terrible optimization: test found that the battery life of 7 iPhone models have declined

Last week, the official version of iOS 14.6 was released. Although the performance degradation (“speed reduction”) problem of the previous version was fixed, it seemed that the price was sacrificed battery life.

It’s not out of nothing to say that. The iAppleBytes found 7 models including iPhone SE, iPhone 6S, iPhone 7, iPhone 8, iPhone XR, iPhone 11, and iPhone SE 2, and compared the battery life test of GeekBench in the official version of iOS 14.6 and iOS 14.5.1.

As can be clearly seen from the picture, compared to the official version of iOS 14.5.1, the battery life of the 7 iPhones has declined on average.


Taking iPhone 11 as an example, the test lasted for 5 hours and 17 minutes under iOS 14.6, which is 8 minutes less than the previous version and 37 minutes less than iOS 14.5.

iPhone SE 2 is the model with the worst battery life this time. Compared with iOS 14.5.1, it has half an hour of battery life.

It is not clear whether Apple will solve the problem in iOS 14.7. If you are particularly concerned about battery life, you may wish to roll back the version or postpone the upgrade to iOS 14.6.
