Can I downgrade my iPhone from iOS 18 to the previous version?

This "update" 18.3.1 is a definite downgrade. Have a job site cellular wifi camera set up 6 months ago with Verizon and it was working like a charm with my iPhone 12 Pro and iPad 12.9 Pro 5th Gen. The phone updated 2 nights ago and I cannot logon to the job site with the iPhone unless I power off, wait a minute and then restart and even then it takes 2-3 times doing this before it logs on. The iPad Pro hasn't updated yet and it logs on almost instantly with 18.1.1 IOS. I also hate the new photos App interface. Its very confusing to use.

Alex ~ Your iPhone XS Max could be 6½ years old and the long process of applying an iOS update to an iPhone with a weak, aging battery can be the proverbial "straw that broke the camel's back." So...

Does your iPhone XS Max still have its original battery?

And what's the Maximum Capacity % here?...

few ppl told me here its probably that i changed battery ,capacity of IPhone,and older model but again its been working normally till i install latest version then everything messed up in it..

Changing the battery is not a problem, but having it done by a provider that is not listed as an Authorized Service Provider would be the problem if that was the case. Those may work normally until any demand is put on it, such as the flashlight or even the increased energy needed for the indexing on your files after an update. You cannot blame the update on a problem with a non-genuine battery if that is the cause.

The only thing that Apple could possibly recommend at that point is a Factory Reset or get another phone and do not make that mistake again.

So... Was the battery replaced at an Apple Store or by other qualified technician using a genuine iPhone battery?...

Yep, that is a problem. Update or not, your battery was going to give you problems. That is a constant issue seen here all the time with a non-genuine battery. The update may have increased battery demand while downloading and indexing the files after the update where you are now seeing the results, but that is like putting diesel fuel in your car and blaming it for not working correctly.

You should prepare yourself for phone shutdowns, increased loss of performance, and charging issues, all of which have been reported due to that battery install. Apple is not likely to provide any service to the phone now, which is why you were told to purchase a new one.

Capacity is 100% it showing in my settings that is 100% when I open health battery but it’s not original so yeah

A battery health reading of 100% after a year of use is a clear indication that something is wrong with the battery or the battery controller that is built into the battery.

I have the same question and would PAY to go back!!! My photos are now a mess. My sense of organization is NOT YOURS. So PLEASE offer a return to previous IOS version. Many Apple clients unhappy. DITCH 18.01 and show you’re listening!

There are a lot of ppl asking this question. The only answer I have seen is reset to factory default and start over. Which is a horrible answer

Wish they would roll back the watch too the battery life is only two hours

What did they say when you talked to them?

可以降为iOS 17的系统，前提是你的iPhone不是最新款的16系列

For slideshow music, tap at the top during a slideshow to get the options, one of them in the top left is a speaker which you can tap to toggle music off/on.

I think everybody knows that it’s the fact that we can’t hear the audio from the video, There should be an option to add music or to not to. I want to hear my videos not ******** music.
