We are accustomed to using energy (electric lights) to create light, and conversely darkness uses no electricity.
So it makes sense that having a black background on your phone will use less battery, doesn’t it ?
One thing is true about black backgrounds . . .
and that is that they make the new Apple ios7 theme easier to read and use.
But when it comes to battery life . . . this is the story.
The screen is made up of pixels that display a colour.
And no matter what colour is displayed, whether pitch black or stark white, the screen is back-lit by a light that is on all the time.
The black pixels block more of the light, making a dark area, but the back light is still on and using power.
So the bottom line is, you cannot save power with a black background.
But as with most things, there is an exception to the rule – screens do not use a solid back light.
Unfortunately this option is not available to everyone – only certain devices use this technology. Probably not enough to make a buying decision, (as there would be more important considerations), but worth knowing about anyway.
The exception to the rule
OLED stands for “organic light emitting diode”, and each pixel on an OLED screen produces its own light.
It uses electricity to produce light and no electricity to produce black, so a black background will use less electricity and extend battery life.
Another way to save power
On an Apple device, click on Settings > Wallpaper & Brightness and then adjust the brightness slider control to your liking.
Remember that reducing the brightness will make the screen harder to read.
And especially if you have poor eyesight, the screen will be much harder to view and read.
In fact, if you are experiencing difficulty with reading your screen, then adjust the brightness up for greater comfort.
Well, that is quite simple really!
What should you do now?
- To save battery, turn down screen brightness.
- To see your screen better, turn up the brightness.
