Hello,
There are different ways to ensure the highest iOS that your device will support is installed on your device.
Any equipment currently running iOS 12.5.7 can't be updated to anything higher.
An iPhone 5S, 6, or 6plus, will only update to iOS 12.5.7
iPhones 6S through 7, and SE(gen. 1), will currently update to iOS 15.7.8
An iPhone 8 or later will only update to the latest iOS, 16.6

When updating, your device will update to the highest version currently available that it will support, or it will just say it is up to date (and can't go any higher) and won't install anything.
