Android Nexus One - Can I save energy with the color scheme?

I am wondering which color scheme is more energy efficient for AMOLED display?

I already decided to control the c-circuit according to the surrounding lighting , thanks to this post :

Some proof, link posted by nickf: Irony without sound: Ow My Eyes . If you read that in a well-lit room, black and white will be most enjoyable to read. If you read it in a dark room, white-on-black will be nicer.

But if I want to save battery power, should I use bright content with a dark background or vice versa?

Is this possible in any case ( they say that it does not work for a simple LCD )?

Yes, you can. The best you can do is use a red black color scheme. Blue is more expensive than green, green is more than red. White is the worst :)

To give you an idea, static blue wallpapers (like a jellyfish in an aquarium) consume more battery than 3D galaxy live wallpapers.

Well, the wikipedia article you are linking to says:

For example, our measurement shows that the commercial QVGA OLED display consumes 3 and 0.7 W, displaying black text on a white background and white text on a black background, respectively.

Thus, in accordance with this, a white-to-black circuit will consume less energy than a black-and-white circuit.

The AnandTech article you are referring to talks about regular LCD monitors, which is a completely different technology for AMOLED.

I think the best thing to do is try: try one color scheme and see how long you can go between charges, and then try another scheme.

The black!! I google in black on my phone at http://bGoog.com to extend battery life. Since using black backgrounds I recharge my phone a lot less! There is information on this at bGoog.com/about

The more black on the screen, the better. Black on black would save a lot of energy on OLED screens, but not too readable. Thus, you find a balance between readability and energy saving with as much ink as possible.

In order from smallest to most:

  • All black
  • One color (e.g. red) text on black
  • Text color (e.g. yellow, cyan, white) on black
  • Any background color other than black

Please note that this does not apply to LCD screens, only OLED. For the LCD, the difference is negligible to a point you can forget about. Sometimes all-whites even use slightly less power, but this is not so different from OLED.
