    I hope currently the entire Apple company is cooking something to complete the issues of iOS 15.4

      Running iOS 15.4 on iPhone 13 here , no battery issues.

        U see ios updates hav problesms too(just like Android) people need to understand it is humans dat are working in at these companies mistakes will always happen but Apple,samsung,Google,Xaiomi etc will fix it that's what matters.

          johnny from germany, 20 Mar 2022So you would like to say, that after a major update iOS 13 ... morePhones don't need time to settle down. An OS is just a system software that runs on a phone. Software is deterministic. Its behavior doesn't change over time. You can wait for a few days if you want, though.

            Installing a new OS on an iPhone triggers a lot of stuff to go on in the background, from indexing to recalibrating the battery. It can give the impression that the battery is draining more rapidly when in fact it isn't.

              5 days review ios15.4 on my 12 pro max . Very stable and snappy update battery is much better (15.3.1 was horrible when it came to battery life, especially in standby mode).
              With 15.4, it has improved a lot, so I have no problems.

See you fall into the same trap so easily you don’t even realise, so sure of your opinion are you that you project it onto others, and thus conflate it with fact.

                it’s funny that you suggest it’s impossible to state an opinion on a preference without making it sound like your stating a fact, yet I manage to avoid doing so quite easily, you can go back through what ever message history I have on here you will not find me saying anything such as ‘iOS is better, there is no doubt about it’

                  johnny from germany, 20 Mar 2022So you would like to say, that after a major update iOS 13 ... moreIt does internal maintenance after every update after which you get slightly elevated battery usage. Not always, but often. It's how Apple keeps iPhones working like brand new even if they are years old without a single factory reset done in between. It's annoying for a day you may say, but in the long run it's amazing. I've never ever had an Android phone that would feel the same as brand new after 3 years. It does on iPhone though and it's really nice.

                          15.4 update on iphone is showing so many bug and slowing charging, heating problem, cellular network disconnected itself. I request to Apple iPhone to discontinue the 15.4 version soon.

Lack of universal back button even in gestures u have to slide from left to right to go back , no right to left option for right hand user , lack of setting in dropdown menu to turn off location , cant adjust icon menu even in shortcut u got rectangle shaped icon only , worst battery at this price point compared to android , camera not meet my expectations.

He doesn't know that I was talking from a general point of view, one that can be true for most people that understand and have used both the type of OS and can draw a comparison to make out which one is better overall. Of course everyone has their own needs to decide what is better, but most people just want the features and base it as a comparison tool to decide

                                      All good here,battery seems the same as 15.3.1. 😁
