Earlier, some YouTube bloggers used the benchmarking software to test the iOS 14.5.1 version and found that the performance of iPhone 12 and iPhone 11 dropped significantly. At the same time, Apple shut down the online verification of iOS 14.5 soon after the release of this version.
This means that users cannot successfully downgrade the old version even if they find that it is stuck. The down-frequency gate incident is a lesson from the past, if the speed limit is restricted again, it is bound to be prosecuted again.
However, after testing, more users found that iOS 14.5.1 version does have a performance degradation problem, and the decline is still relatively large, which can be clearly perceived. For example, there are obvious freezes when playing certain games.
This is in iOS 14.5 version and It did not appear in the previous version. At the same time, the performance of the iPhone 12 and iPhone 11 after upgrading to iOS 14.5.1 is not as good as the same upgraded iPhone XR from the benchmark test.

Although Apple did not respond, it also admitted the problem:
Although the performance degradation problem has been reported by many technology media and has attracted attention, Apple officials have not responded to the performance degradation caused by the new version. What’s interesting is that Apple launched iOS 14.6 Beta 3 to developers yesterday.
In the update log of this version, Apple clearly stated that it is used to fix the performance degradation problem. In fact, the iOS & iPad OS 14.6 Beta 3 version also only has this update content, which means that this version may be specifically used by Apple to repair performance degradation. However, this version is still a beta version, so consumers who have updated the official version of iOS 14.5.1 still need to wait. The release time of the official version of iOS 14.6 is unknown.
After upgrading the beta version, the running scores return to normal:
Regarding this issue, V2EX netizen ZJUSTER also conducted tests. After upgrading to iOS 14.5.1, many games such as Yuanshen, Honor of the King, etc. have severely stalled. After testing with benchmark software, we found that iOS 14.5.1 can only reach more than 2000 points.
Under normal circumstances, the benchmark score should be close to 4000 points. This user re-ran the benchmark test after upgrading the iOS 14.6 Beta version, and now the score has returned to more than 3900 points, and there is no longer any lag in various games. Note: Ordinary consumers are not recommended to use the iOS 14.6 Beta series of test versions. These test versions may have stability issues and are only recommended for professional users to upgrade.
