iPhone users, don't upgrade the official version of iOS 15.4!
At present, many users at home and abroad say that after upgrading iOS 15.4, there have been many problems, especially the abnormal use of battery capacity, that is, the battery life is far less than before the upgrade.
In social media, many iPhone users bluntly said that after the upgrade, the storage capacity of the mobile phone declined, the battery life dropped significantly, and many users ran out of battery for half a day!
On the part of Apple, the attitude is also very tough, and the official reply said that this is a "normal phenomenon" and called on users to "try it again".
It's a huge disappointment to iPhone users!
Then Apple realized the seriousness of the problem, saying that due to the reduction of storage space in a short period of time after the upgrade, the battery life will cause battery life problems in the first few days after the upgrade, and it is recommended that users after the upgrade use it for a period of time, if there is any abnormality, please contact Apple's official customers.
I really haven't found which phone has problems with the hardware of the phone because of the system update, and the iPhone is the first and only one!
Here's a call to Apple to solve the problem as soon as possible, don't "play Tai Chi"!
