iPhone X Will upgrading my X from 11.3 to the current firmware diminish battery life and performance?

It might improve when compared to a non-restored iPhone on iOS 14, but it won’t be anywhere near iOS 11.

Like how much of a difference are we talking between 11 and 14, an hour?

Dunno. I guess 20-40% less. So if you were getting 5 hrs from 100 to 0% you might get 3-4.

The vast majority of iOS 11 screenshots for the iPhone X were between 8 and 9 hours. On iOS 14, they seem to be around 6 hours of screen-on time.
That’s around a 25-35% decrease within three iOS updates.

To be honest, that’s A LOT better than it used to be.

On the money.

But you still wouldn’t update?
