As early as a week ago, I was inquiring when the official version of iOS15.4.1 was released, and finally yesterday the version was finally pushed, and I also upgraded the official version of iOS15.4.1 at the first time I learned the news, and my mother has been heavily used for two days, as an iPhone12 user said that a few points are different from the online review experience.
As we all know, the biggest highlight of the official version of iOS 15.4.1 is that it solves the bug that the power consumption of the previous version (iOS 15.4 official version) is too fast. And I have risen from the previous version or have more say. Some netizens said that the official version of iOS15.4.1 has dropped the battery faster. But my 12 was luckier and the battery life was much better.
But in other experiences, I was so lucky, these two days my 12 opened the storage space and began to turn endlessly, the last version is not the case. At the same time, after the upgrade, my 12 can't use the 5G network, showing that there is a 5G signal but it can't be used, which is a bit unbearable, but after switching to the 4G network, it can be used normally.
In addition, the camera flashback problem that appeared in previous versions is back in the official version of iOS 15.4.1. So on the whole, iOS15.4.1 official version and iOS15.4. official version of half a pound eight two, to persuade students with more stable mobile phone systems not to fool around.
