My Apple Watch 6 lasts at least 30% longer with AoD turned off. Has a massive impact to battery life.More than likely Apple is going to use the same implementation as found in the watch:
Anyone saying "kiss your battery life goodbye" has not been using a newer Apple Watch for the last few years.
- Mute colors
- Lower brightness
- Drastically reduce refresh rate (I believe all the way down to 1Hz)
That being said, I think that has more to do with the tiny battery in the watch.
