When I connect to my MacBook Air. it's popped up to download and install software update on my iPhone 15 Pro. I Just wondering the latest software update is 8.28GB. Is this normal? can someone answer me please?
iPhone 15 Pro, iOS 17
Yes, that is normal. Software updates for iPhone downloaded on a computer can be fairly large since it has to download the complete update before.
Software Updates directly on the iPhone download partials, i.e just the things that may have changed between the version you are currently running and the new one, so tend to be smaller in general.
