Will the battery life of iPhone 12 Pro Max get worse after upgrading to iOS15.7

Apple officially released the iOS16 system, but according to the postscript evaluation of iOS16 in recent days, this system is really a bit buggy for some older models, and the main problem that everyone fears most is the endurance. After all, Apple's own endurance is not good, so there is not much update to iOS16. Fortunately, there is another iOS15.7. How about the endurance of this system? Now let's make up for you.

Will the battery life of the iPhone 12 Pro Max get worse when it is upgraded to iOS15.7

Postscript of netizen upgrade:

Felt it was fairly good. The 12PM 15.5 upgrade was 15.7. At present, it doesn't generate heat. The signal is fairly good

12pm 15.7 Very satisfied with the current endurance and heat

It's better than 15.6, but it's not too hot to play games. IOS16 doesn't give any hope, and 15.7 is good for elderly care

Advantages of IOS 15.7

1. Endurance

The battery life performance of iOS 15.6 is not satisfactory. The power consumption of 5-6 hours of standby every night is about 5-6%. The previous factory system consumed about 2% of power every night. The power consumption of upgrading to iOS 15.7 is only 3%, which is almost the same as that of the factory system. After the 3-hour battery life test, the remaining power of iOS 15.6 is 41%. The remaining power of the same 3-hour battery life test upgraded to iOS 15.7 is 48%. The battery life is improved to a certain extent.

2. Signal

In iOS 15.6, when I went to some business districts with large traffic, the signal immediately only had 1-2 grids, and the network speed was significantly reduced. In the special scenarios such as upgrading to iOS 15.7 business districts with large traffic, the signal could be kept at 2-3 grids, and the network speed was much better than before.

3. Smoothness

There are still some frames stuck in iOS 15.6, mainly due to multi task switching frames, Taobao and other apps sliding frames, and upgrading to iOS 15.7. The situation of frames stuck in iOS 15.6 is obviously improved. The sliding in Taobao and other apps is very smooth. In addition, the game loading speed is faster than iOS 15.5.

It is still possible to upgrade the iPhone 12 Pro Max to iOS 15.7. Many 12pm users have decided to rely on iOS 15.7 for retirement, and many users have downgraded to iOS 15.7 after experiencing iOS 16, so it seems that the relevant comments are good.
