iOS 15.4 Battery Drain

Is anyone experiencing battery drain since updating their iPhone to iOS 15.4? I am considering updating this morning and have seen this be an issue with other updates in the past.

Tucch ~ And what about folks who have old iPhones who don't have 100% healthy batteries? ...For them, the long process of applying an iOS update to their old iPhone with a weak battery can be the proverbial "straw that broke the camel's back."

Or what about folks who've replaced their battery with a non-genuine Apple battery that now incorrectly shows 100% when the fake battery is actually failing?

...Neither of those cases have anything to do with a faulty iOS. For that reason, we'll not stop asking for the iPhone model and Maximum Capacity %. Such basic info should be stated in the first post anyway – without having to ask and then finding out it's an old iPhone 6s with only 75% Maximum Capacity!

BTW, one thing I forgot to mention before thanking you for all your help, I do have an old iPhone 6s that was very recently sent directly to Apple for a new battery and updated to the latest ios it could accept by Apple and shows 100% health. It has no apps on it other than what Apple puts on them and it still drains within a short period, even when powered off. It actually lasted much longer on the original battery with 75% health. Apple says nothing is wrong with the phone. Already done all the trouble shooting and spent long hours with their customer support and tried all the suggested fixes here with no solution. It was a back up anyway, but now my 6s is not even considered a backup. My mistake for getting a new battery put in by Apple.


This is just my experience and I am now not going to suggest this is happening to anyone else and apologize for any other posts.


So, once again thanks for your help.
