That's up to you; once the curtain is off, the phone doesn't have to be at all that much of a bright setting for sighted people with close to normal visual acuity to use. People who have lower vision may want a brighter screen.

In either event, the screen curtain will make it almost impossible for them to use the phone. But when we're using Voiceover, it is fine. There is debate that it may also save some battery life; I'm certain it likely does over a quite bright screen if the phone is left on for most of the time.

Additional things that can save battery: Put your phone on auto-brightness instead of setting to a bright setting; disabling app refresh, disabling bluetooth and wireless unless needed, disabling motion effects under the wallpaper settings, disabling location services unless you need them for specific apps, etc.

Subject: Screen courtain.


My apologies for such a newbee question, but I just want to make sure
that I fully understand the functionality of screen courtain.  I only
just realized what might be happening with this feature.  I had turned
the brightness way down on my screen, and had probably engaged screen
courtain at some point.  When I was attempting to show my wife some
pictures, she said she couldn't see anything, so I turned up the
brightness.  She still couldn't see anything.  She said the screen was
black, so I did the three finger triple tap to turn off the screen
courtain, and all was happy.

So, my question is, should I just leave brightness at a high setting
so the screen is easily read by a sighted person when screen courtain
is off, and just keep the screen courtain on whenever I am using the
phone?

I had always assumed that the courtain was dynamic and was only on
when the phone was locked.  Since it seems to be a persistent thing,
then there doesn't seem to be a need for me to keep brightness turned
down.

Thanks.
