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

IOS16 has been released, and Apple has also left a way for users to back off in case some models are not suitable for iOS16. For example, recently, users who have taken over the iPhone 12 Pro said that they were hot after updating iOS16 and lost power quickly, so they directly swiped back to 15.6.1! But now Apple has closed the iOS 15.6.1 authentication channel, but fortunately, iOS 15.7 still exists. How does the system perform in terms of endurance?

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

Postscript of netizen upgrade:

The 12pro has been flushed, very good! Old age

The 12pro power failure is normal. Another three years!

Don't update ios16. I was downgraded to 15.7 after updating 16.

There are many bugs after iOS 16 is adapted to 12. It is degraded. IOS 15.7 is OK. It is not hot

Recently, many iPhone users have spoken on Apple's official forums and social platforms, saying that their iOS 16 service life is very bad after upgrading, including the iPhone 13, iPhone 12 and other old models.

A microblog user said: If I hadn't called the after-sales service and returned the ios 15, I would have replaced it with 14

In this case, Apple said that enabling haptic feedback for the keyboard in iOS 16 may consume power, so users who encounter battery depletion can try to turn it off.

The battery life of the iPhone 12 Pro upgraded to iOS 15.7 seems to be OK. At present, most users' feedback after the update is relatively positive, so if you are not sure about the battery life of ios 16, you can still choose ios 15.7 for pension.
