Hello Jenny, I just had a look at Settings > Display and Brightness and you have to realize that there are two entirely separate things here. At the top you have "Appearance" and here you can select either "Light", "Dark" or "Auto". This refers to the colour scheme, light mode, dark mode or automatic. In dark mode the screen emits less light, backgrounds are dark and text is lighter. In light mode it is the opposite, backgrounds are very light and text or other things are darker. On phones with OLED screens dark mode will use a bit less power because darjk pixels consume less power which is why turning on screen curtain where the entire screen has only black pixels will save some power. I am not entirely sure when "auto" is selected when light or dark is used, but I would recommend that you should turn your Appearance to "dark".
The next area is screen brightness and once again, the higher of a percentage you see there the more battery is used. If screen brightness is set to auto the screen adjusts based on the light around you. In a dark room a sighted person can see the screen perfectly well with the brightness at 0%, but if you were outside in bright sunlight and you wanted to show somebody something on your phone they probably couldn't see hardly anything that way and brightness would have to be turned up to probably at least 50% or 60%. The best option is to set screen brightness to auto. As Richard pointed out Apple has set it up so that if Voiceover is running and you turn on the screen curtain, brightness is reduced to 0% and this will be optimal for battery saving. However, if you are in a position where a sighted person might want to take a look at your phone then as soon as you either turn the screen curtain off or if you turn Voiceover off entirely, the screen will once again be visible and brightness will be at a level where it is easy for a sighted person to see it. The next item in Display and Brightness is "True Tone". There is an explanation below it so I won't go into it, but I turn it on because I do often show sighted people my screen because maybe I want to show them a picture or whatever, and then I prefer it to look as good as possible. Nightshift is the next item and for a blind person it is of little concern, you can read what it is by tappin on it. The next two buttons are also important, Auto Lock determins how quickly your iPhone's screen locks when you don't use it and of course this also has a big impact on battery life. I know there are some how set this to "Never" as they prefer to always lock their screen by pressing the side button. I personally am not one of them and I want my screen to lock quickly, but maybe not totally quickly so instead of 30 seconds which is the shortest time I set auto lock to 1 minute. Lastly there is the "Raise to Wake" which I believe most of turn off. If you turn it on the screen wakes up as soon as you raise your phone from the table or take it out of your pocket, belt holster or purse. I prefer to wake my phone up manually by tapping the screen or pressing the side button. The "Tap to wake" is also a setting you can turn on and off, I think it's somewhere in accessibility settings. To summarize again, turn "Dark" on under Appearance, select "auto" for brightness and turn Raise to wake off. Then turn the screen curtain on if you want the most battery saving. Of course there are other settings which probably make more of a difference on battery life than screen curtain, things like how much you use background app refresh, what you allow in location services is a big one and also if you have an email address set up whether you use Push or only tell it to get email every 30 minutes or even manually when you open the Mail app. It's always a trade off between features/convenience and battery life. I personally couldn't care less if my phone is at 40% or 20% at the end of the day, I rather have less battery left and get the most out of the features I want including getting email as it arrives.

When I went to settings and turned auto on now voiceover says light. Which I know you said didn’t make any difference I just thought you guys would like to know. And that’s a good thing I went through because it said it was at 16% but I switched it to zero referring to the brightness when it had changed to light once I turned on automatic. Thanks for reading regarding this matter. Jenny Bomareto Sent from my iPhone -- The following information is important for all members of the V iPhone list.
