Is this how backups work with your personal computers?

Yes, if I do a full restore, I expect all files and settings to be restored, including bugs present at the time the backup was made.

iOS backup apparently doesn't work like you described. E.g., when restoring a backup from iOS 14, it doesn't revert your system to iOS 14. Clearly there's a separation of restoring the executables and restoring the configs.

I do expect "the config/setup that would trigger a battery drain in <iOS X" to be restored, but Apple can always fix iOS so that the same config/setup won't break >=iOS X.

If you do a full restore implies that you don't have to do that.

And yeah as the other commenter said, that's not really how the ios one works.
