After I upgrade to 15.4.1 I noticed the battery drain faster . How I go back to only 15.4
You cannot go back. The battery will work overtime for a few days until the update is complete. Check this link...
Sorry yesim666 they unsigned 15.4 , look like they want to force people to use 15.4.1 maybe that was their plan to do that for people go buy new iPhone I guess , all You can do now just wait till 15.5 come
That’s not true because I have been rested my phone hopefully it will get fix but disappointed and I just downgrade to my previous iOS 15.4 using iTunes because the new update 15.4.1 is trash shame on you Apple
Kyle46 go back to 15.4 using iTunes just go to ipsw website download Your phone model firmware and install it using iTunes , because 15.4.1 is trash apple was blind when did this update

I have updated from ios 15.4 to 15.4.1 with the knowledge that it is going to fix my battery. But after updating i am losing the charge like anything. I lost 10% charge just after one phone call. Apple please fix this battery problem which is very important. My model is 13 mini
My iPhone 11 Pro Max was at iOS 15.2 and the battery life was a bit bad then I updated to 15.4.1 and it drains even faster like I used an hour less and it drained the same amount of power
Sorry i am very new to this community. Thank you for your help.
Question: The IPSW website says that 15.4 is "unsigned" and won't install from iTunes. Any work around to go back to that version. 15.4.1 suck battery life out of my iPhone 12. Thanks.
Hey yesiam666 . I have signed copy of 15.4 for my device I don’t know if still good or Apple check the sign every time You use iTunes.
iOS 15.4.1 is bad , drain the battery faster then before 🙄
