There is one difference between them,
you can chance the n900 battery

What if one used a theme which requires more brightness such as a white theme?

Is that a joke?

I'll just change my laptop's wallpaper to solid black to improve my battery life!

That's not how LCDs work. The light comes from a backlight behind the LCD, then the LCD blocks bits of the light off to make the image. A dark image still has the backlight using the same amount of power as a light one.

Was this usage with calls over 3g? or idle?

Hope to hear from you, gracias.
Of course I was connected to normal cellular network whole the time and made some calls.I had normal daily routines and there was about 10 calls (1min to 20 min). I meant with 3G that I had 3G connected.

It's true. A white background can safe you a few mWh's.
I tested this extensively on my old x24 thinkpad.

But it will in no way have any noticeable impact on overall battery life (could give you a few extra seconds, not more).

With normal use I can assure You that N900 battery holds much longer than Your phone, It holds easily 14-16 hours in heavy use. With moderate use it holds two days. And you can carry spare battery with You.

Thanks, interesting. So the light has no dimmer, makes sense, LED. Is the reverse true though? In a white theme you could set the brightness very low and still see everything well whereas the same is not possible with a dark theme. Or does brightness not affect battery life at all?

If so, I'd find that rather strange because my laptop's screen is considerably darker when disconnected from AC instead running on battery. This is default configuration set by gnome-power-manager settings.

Also, my Nokia E71 boots up with very dimmed logo. Almost not able to see. Only after it asks for PIN it will light up normally, and after 15 sec no interaction it will already set to a more dimmed screen (again, default power settings).

The backlight intensity can be varied. What I was trying to say was that the power consumption didn't vary depending on what image is display, whether a light image or a dark image.

Just for that reason the light sensor is on most phones. When in dark room, you don't need the backlight at full.

Plasma and AMOLED screens differ from LCD's as the pixels in them actually create the light. You actually get better battery life on AMOLED devices when using dark theme etc.
