And I need to use certain updates but my current iOS version doesn't support it. But now I'm kinda left with no choice because my phone's battery is already draining fast as I've had this phone for 5 years now. You probably have tons of junk data and apps lying around that you never use. Some of the benefits of a clean install might be. To be clear, there’s absolutely no need to clean install the next version of iOS. If you already know your iPhone Model (such as iPhone 13, or iPhone 12 Pro Max), you can skip this section and move to the next. On iOS, the situation may be a bit different. Could the problem be that my iPhone 7 is too behind on the iOS updates? Because I've heard many people saying their phones' battery drain faster when updating, so I didn't bother updating it. To downgrade your iOS version, you'll need to know your iPhone Model so you can select the proper software to download. I've tried everything and even contacted Apple Support. I just downloaded iTunes onto my laptop a few days ago and when I check what version my iTunes is, it says "This version of iTunes (12.10.11) is the current version." I keep trying to update my phone, and sometimes it does "update" but after it finishes updating, I check and it's still 11.4 (15F79).

However, every time I try to update it, I always get a pop up message that says something along the lines of "There was an error with trying to update to iOS 15.7." I've tried every method and even loaded iTunes onto my computer to try and force my phone to update, but whenever I do that, I get a message on ITunes saying that I need to get the latest version of iTunes in order to update my phone. IPhone 7 won't update to iOS 15.7 I need to update my iPhone 7 that is running on iOS 11.4 (15F79) to the latest iOS 15.7 (it's supported) to be able to run a lot of apps that I now need to use.
