Hoping for the stars and the moon, Apple's iOS operating system was finally updated in the early hours of this morning. I thought that this time Apple will update iOS 15.3 Beta2, did not expect to bring iOS 15.2.1 official version, considering that the official version of all aspects of the performance should be more stable, after thinking about it, upgraded the iOS15.2.1 official version.
About the advantages of the official version of iOS15.2.1: 1, it solves the bug that I put voice message delay in iOS15.2, and it takes several seconds to wait for the recording key to send WeChat voice before the upgrade, and now it is normal;
2, iOS15.2.1 official version to solve the iOS15.2 easy card machine and other BUGs, in the past with the original camera shooting, if just after filming with WeChat, Weibo and other Apps to send out, the mobile phone will be directly stuck to the machine. Today after heavy use it was found that this problem has been fixed;
3. The official version of iOS15.2.1 solves the phenomenon of frame drop caused by opening software and multitasking pages in iOS15.2.
Regarding the shortcomings, at present, only the official version of iOS 15.2.1 is found to be more power-hungry, after the upgrade is shut down and restarted, it is 9% of the power loss in five minutes, although it will be relatively more power-consuming after the upgrade, but this is also too exaggerated. Still, I feel that the official iOS 15.2.1 version has a better experience than iOS 15.2.
