I have to say that the update speed of Apple's operating system is getting faster and faster, less than a week apart, Apple has updated the first beta version of iOS 15.3, the version number is 19D5026g. After heavy use, share part of the experience of using this version.
The most amazing thing about this version is that the signal is better, although the signal in the previous version is not bad, but I did not expect that the iOS15.3 Beta1 signal can be better, specifically in the past my 12P in the elevator or underground garage there is a relatively biased highway lot signal is not very good, will drop one or two blocks, originally thought that this is a normal phenomenon Everyone is the same, but after upgrading iOS15.3 Beta1, the signal is full.
At the same time, the battery life of iOS15.3 Beta1 is also stronger than my previous version (iOS15.2 official version), before the full power standby overnight power loss of 12%, since the upgrade has been two consecutive nights of power loss 7%, but this version of fluency is slightly inferior to the iOS 15.2 official version, occasionally sliding the screen too fast will electrocute the phenomenon of Caton, but the frequency is very low basically will not affect the experience.
Although it is the first beta version of iOS 15.3, but the sense of experience is actually not lost to the official version of iOS 15.2, or even better, it can be said that iOS 15.3 can be expected in the future, I hope that the official version has better performance.
