The XR is still using LCD technology. You're right, theoretically you
should save some power on an OLED display if you're displaying a lot of
black since it isn't back lit, but since the XR is the battery king, I
think you're also right that in practice this is barely noticeable.

just because brightness is 0%. Otherwise iOS 12 has nothing to do with it, I
think on iPhones with an OLED screen which has no backlighting, theoretically
turning screen curtain on should save a bit of battery life, that would be the
iPhone X, XR, XS and XS Max, but then again I assume it's such a tiny amount
that it wouldn't matter.

Subject: Screen curtain and battery?
Does the screen curtain save battery now on all iPhone models running iOS 12?
Thanks
