At night, in the dark, even at its dimmest setting, my iPhone 4S is still bright enough to annoy my wife. I've searched all over for an app or setting tweak that would let me go "dimmer than dim". But no app seems able to do that and the only tweaks I've seen are for jailbroken phones (mine is not).

Does anyone know how I can make the screen dimmer?

By definition, the software only allows certain brightness levels so only by modifying that software (jailbreak or perhaps Apple changes things) can you go dimmer.

There are many apps that use the colors and draw dimmer text (Instapaper uses black background at night and many stargazing apps only draw in red). You could try using the accessability features to invert the white / black system wide. Even though the screen is still as bright, the largely black screen will block most of the light from escaping. You can even set the triple press of the home button to toggle this rapidly.

Lastly, there are 3M polarized privacy screens (watch for vertical or horizontal privacy - most only work in one direction) to help solve the light escaping to your side issue.

If she is seeing the light reflect off of you, you're going to have to look for other options. Psychologically, most people can fall asleep with light, but light and motion or light and noise are much harder to sleep with. Hopefully it's just the light as you might just need to drop the phone or move to another location if it's not really the light that's the source of the irritation.

(I'm the OP) Yeah, Instapaper's (and others') techniques are fine for reading apps. But I was more concerned with "mega" dimming screen brightness system-wide. I watch videos (sound via earphones) and it's their brightness, even at the lowest setting, that bothers her. –  user249493 Jun 14 '12 at 18:22
    
Well - the black/white inversion won't help much for videos and might make it worse. You might really like a landscape polarized film in this case. I've heard people make do with a pillow to block the light too. –  bmike Jun 14 '12 at 18:25

Without jailbreak, it's not possible.

I can even generalize and say that no app will ever be allowed to modify such system preferences.

I often use "Night web browser by Alex" when I'm in bed and my girlfriend is trying to sleep. It dims the screen much more then iPhone can normally.

This will work assuming that the OP is only interested in web browsing. It won't help with any other apps though. –  daviewales Jun 17 '13 at 22:40

wait for iOS 6, at least I think the dim function is improved since I installed iOS 6 ( I switched from a Jailbroken iOS 5 to 6 so I'm not 100% sure )

I dont know if you are still having the problem, but I use the Dolphin Browser on my iphone and it has a "night mode" feature that makes the screen pretty dark. Maybe that would be helpful. Thats for a non-jailbroken phone. I believe it was free also! My phone is jailbroken & I also had the same problem so I downloaded a tweak called f.lux. It doesnt necessarily make the screen dark...it has settings for day & night which have adjustments that give it a dimmer more orangey halogen light for night instead of the bright white like in the new energy saving bulbs. You can adjust that setting along with the brightness setting on your phone to get it dimmer and not so annoying. It will dim everyday at a certain time( like 5 or 6pm) and goes back to your preset day settings in the morning. I found it to be pretty helpful. Im not sure if it can be installed on a non-jailbroken phone though since I got it from Cydia. I can try & research it and let you know..if you are interested.

You could also invert colors: Settings > general > accessibility > invert colors

All white will become black!

I would think that, since videos are mainly what you're doing, night browser is your best bet. It lets you go very dark and do anything safari can do (including go to YouTube and play your vids in QuickTime player). For just navigating around, if you go into your accessibility settings, you can make it so that a triple-tap of the home button inverts colours-it's a very easy shortcut.
