This is the easiest option available to download an older version of an app, but one that you may not know about.

Let Apple Download the Last Compatible Version And it's far easier than you might think! So, here are all the options you have to download old versions of apps. And I need to use certain updates but my current iOS version doesn't support it.Luckily, you can download older versions of apps on your iPhone in several safe and legal ways. 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. 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. 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.
