On April 8, Apple pushed the iOS 16.4.1 update (build number: 20E252), 11 days after the last release! Last time, it was the official push of iOS16.4! This update is recommended for iOS 16.4 users, mainly fixing several major bugs!
The installation package is very small, and the other improvements on the front will be minimal or none, and the upgrade content given on the official day is: fix the problem that push watch emojis do not show skin tone selection, fix the problem that Siri does not respond in some scenarios, but many people in the last official version have reacted to the serious shrinkage of many iPhone battery life (the author's iPhone 13PM and iPhone 14 are not obviously perceived).
Among them, continuous intercommunication leads to the inability to use universal control normally, the former is the function of Apple's ecological linkage, iPad, Apple Wtach and other functions that can receive calls, and universal control is the function of content transmission and dragging and dropping between devices. However, this iOS 16.4.1 update day is not mentioned!
According to the content of Figure 1 above, the log mentions IOSurfaceAccelerator, which should be translated as iOS surface acceleration, including iPhone 8 and newer models, iPad Pro (all models), iPad Air third generation and above models, iPad fifth generation and above iPad mini fifth generation! The main thing is to fix the hacker's vulnerability, but about this feature of iOS acceleration, it seems that I have never heard of it before.
In addition, about the iOS 16.4 weather APP can not display the location of the bug, has been fixed, without updating can also be displayed normally, but about the above several battery life interaction problems reflected by everyone, there is no news, in addition, near the release of IOS17, a lot of news about earlier models will stop updating also increased, after all, software optimization still needs to rely on hardware performance, so it is recommended that the current can still be updated online version of the old model as much as possible.
