Screen curtain on iPhone
Hello, I am concerned about battery life on my ageing iPhone 3GS running the latest level of IOS 6 (IOS 7 does not work on the 3GS). I know that reducing screen brightness increases battery life. If I set screen curtain on does that have the same effect as setting screen brightness to 0? If I set brightness to say 40% and normally run with screen curtain on I can easily toggle screen curtain off to show the phone content to a sighted person. However if normally setting screen curtain on in this scenario does not improve battery life then there is no point in doing this. Instead I would have to run with screen brightness normally set to 0 and to remember to temporarily increase screen brightness to show the phone to a sighted person. Many thanks.

Re: Screen curtain on iPhone
I would put the screen brightness to 0 then adjust it where necessary. Screen curtain only puts a virtual curtain around your screen and doesn't affect how it contrasts.

Re: Screen curtain on iPhone
I would think that screen curtain being on would save more battery life, as I'm sure that even when it is set to zero, display processes are still being sent to the screen, and when screen curtain is on, I'm guessing that the processes are not calculated by the processor.

Re: Screen curtain on iPhone
Last I heard, the official word from Apple Accessibility was that the IOS screen curtain has no effect on battery life. BTW, though I’ve done no official testing, my personal experience leads me to believe this also holds true for the MacOS screen curtain on Macbooks.

How to activate the MacOS screen curtain {Was: Re: Screen curtain on iPhone}
Press VO+HH to get to the VoiceOver Commands help menu, then type screen curtain to narrow the results. At this point VO should announce the shortcut key VO+Shift+F11 and, if you’d like, you can press Return to toggle the screen curtain or press escape to exit the VO Commands Help menu.

Re: Screen curtain on iPhone
Yes, I’ve heard this anecdote from a number of different folks over the years. Unfortunately, AFAIK none of these folks have produced any hard evidence to show that turning the screen curtain on actually increases battery life. I’d love to see a controlled and replicable study to either prove or disprove the assertions of those of us including Apple who believe there’s no difference in battery life with or without screen curtain.

Re: Screen curtain on iPhone
Bryan, I might be wrong on this, so please don't quote me here, but if I am understanding things correctly, I don't think it saves battery life, and here's why more specifically: All that really happens notably when you enable the screen curtain is that it virtually paints a black shadening (if that be a word,) over the screen. Think of it like this: you have a pare of sunglasses. Now, if you was to take those and paint black paint over their lenses, that's basically in a nutshell what you're doing with the screen curtain. You're not really per sé making the screen power/brightness any less intense. You're basically just drawing solid black highlight over the top of it, thus, nulling/blacking it out. If you really want to truely increase your battery life, your better bet would probably be to go into settings, and turn the screen brightness all the way down to 0%. And no, doing that plus enabling the curtain really wouldn't probably have any ill effect, no, but I don't really think it would help matters either. Now, that said, your screen brightness certainly would make a huge difference.

Re: Screen curtain on iPhone
The thing about any testimonials is they are all subjective. Someone else using the screen curtain exclusively may not get as good of battery life because of battery care, or the lack there of. I drain my battery probably every other week and plug it in at bedtime. I never, never unplug the phone unless it has charged to 100%. I think that the only ones who can conclusively say which is better are the folks who are responsible for writing the IOS. But it still seems logical to me that the screen curtain is more of a complete shut-off as apposed to a fade-out of the screen.

Re: Screen curtain on iPhone
Chris, I believe that the screen curtain turns off the back-light, thus making it black, like it is when there is no power to the phone. There is no black in terms of pixels, there are colored pixels that get back-light, or no light behind them, thus causing blackness.

It is shift control option f11 to toggle screen curtain on and off.

Re: Screen curtain on iPhone
Actually, those with vision report that if you turn screen curtain on in a darkened room you can easily see that there is light still on. Chris's explanation seems consistent with this observation. On the other hand, I have had great battery life on my MacBookAir just keeping the screen brightness and keyboard brightness down to zero when using it on battery. This can be done by: turn the screen brightness down by pressing and holding the F1 key (increase brightness by pressing and holding F2) and decrease the keyboard backlight to zero by pressing and holding down the F5 key. To share my own experience, I can use my Air which is several years old now for about 4 hours on battery. I have not paid enough attention to my typical battery life on my iPod to make it worth trying to share that, though.

There is no black in terms of pixels, there are colored pixels that get back-light, or no light behind them, thus causing blackness.

Think of it like this: you have a pare of sunglasses. Now, if you was to take those and paint black paint over their lenses, that's basically in a nutshell what you're doing with the screen curtain. You're not really per sé making the screen power/brightness any less intense. You're basically just drawing solid black highlight over the top of it, thus, nulling/blacking it out. If you really want to truely increase your battery life, your better bet would probably be to go into settings, and turn the screen brightness all the way down to 0%. And no, doing that plus enabling the curtain really wouldn't probably have any ill effect, no, but I don't really think it would help matters either. Now, that said, your screen brightness certainly would make a huge difference.
