That's Not True, as ScreenCurtain (i.e., Dark Screen) does Help "improve" BatteryLife on MobilePhones with OLED TouchScreens, but ScreenCurtain/DarkScreen doesn't on LCD TouchScreens: that is "why" BatteryLife was Not Impacted by a User using ScreenCurtain on iPhones prior to Apple's AnniversaryEdition, the iPhoneX, as it was the 1st iPhone released by Apple with an OLED TouchScreen

Note:
Apple's iPhone11 & iPhoneSE 2020 as well as its iPhoneXR don't have OLED TouchScreens, so ScreenCurtain wouldn't improve BatteryLife on Them

But it will "improve" Battery Life on the iPhoneX, iPhoneXS,iPhoneXS MAX, iPhone11PRO, & iPhone11PRO MAX

Screen curtain does nothing to save battery, as the display is still on, but blacked out for privacy. Setting brightness to 0 does save battery life.

Right.
Screen curtain won't help that much if auto brightness is turned off.
My first gen SE and my SE 2020, both stay at zero so long as Screen Curtian is on as well as auto brightness.

I keep the screen curtain on and auto brightness turned off. And, my screen brightness creeps upwards as the days go by.

Thanks Dave. I went into my settings, and auto brightness was turned off. But sometimes brightness moves from zero, anyway. I must make sure to check it daily just in case.

You have probably got your auto brightness set to on.

I have this same question. But, my brightness setting creeps down instead of creeping up. How strange.

Subject: keeping brightness at zero to save battery

Hello iPhone listers,

In the control center, I have brightness set to zero percent except when sighted assistance is needed. But, I've noticed lately that I have to check brightness regularly because it doesn't always stay at zero. I check it when I think I'm suddenly using up too much battery life. Any suggestions for why the brightness would change without my doing anything to change it?


Peace & Blessings,
