Apple “God Optimized” iOS 14.5.1: iPhone 12 performance is actually not as good as XR

If you are a user of iPhone 11 and 12 series devices, don’t worry about upgrading to iOS 14.5.1, because many users have already reported new problems.

Now, a foreign digital anchor shared a video, comparing the performance of iPhone 11/12 and iPhone XR, and the performance of XR is better.

Compared with the iPhone 11, the iPhone XR’s video rendering speed, boot time, application loading time are faster, and the benchmark score test is also better. Therefore, this performance problem should appear on iOS 14.5.1 system.

In addition to the performance of the iPhone 11, the iPhone 12 also faces a similar fate in terms of benchmark scores. Although the single-core score is acceptable, the multi-core performance is lower than the iPhone XR. The benchmark test is repeatedly recorded, it can only show that iOS 14.5.1 insists on performance throttling.

In addition, in the 3DMark benchmark test, iPhone XR performed better than iPhone 12 and iPhone 11. Please note that the performance throttling is not due to heat issues, because the device did not heat up or get hot during the test.

iOS 14.5.1 is a major update that brings a security vulnerability patch for WebKit. Therefore, we still don’t know why the latest update will slow down the CPU performance of iPhone 11 and iPhone 12. This problem did not appear in the iOS 14.5 update, which is a very important update, related to the number of forward supplements it provides.
