Some time ago, Apple officially released iOS 14.5. Since it is the biggest upgrade since the release of Apple's iOS 14, many Apple users upgraded the system for the first time, and have been praised by many people since then. However, Apple's recently launched iOS 14.5.1 seems to be a bit of a rollover.
The reason is that some foreign bloggers found that after also upgrading iOS 14.5.1, the iPhone XR is ahead of the iPhone 12 and iPhone 11 in terms of boot time, image rendering, and benchmarking tests. The iPhone XR was released in 2018, and it has a generational difference with the latter two mobile phones in terms of hardware, but after updating the system, the performance is even better, so I have to say that Apple has a bit of reverse optimization this time. .
However, this also explains to a certain extent the importance of the iOS system to the of Apple's mobile phone. It has always been said that the most powerful of Apple's mobile phone is not the hardware, but the system. Now it does not seem unreasonable. After all, it is rare in the mobile phone industry that a system update has such a great impact on the performance of a mobile phone.
In addition, there is no official confirmation and interpretation of as to why this happens, but the specific reason should be clear soon. What do you think of it? Do you think this is a common occurrence, or is it just a case in point? Is there any user who has upgraded, please explain it to everyone in the comment area.
