Why you should have a black background. If you have a smartphone, laptop or TV that has AMOLED (OLED), you should take a black background. Now you ask why? This has various reasons.
Consumes less power / battery
This can be very good if you are outside for a long time. You can’t charge your phone somewhere.
If you have a black background, the black pixels are automatically switched off with OLED, so you can save battery.
It’s not bright
When you’re outside, the bright screen of your phone can dazzle you.
Then you walk on the street and an accident happens because you didn’t see anything…
Actually, it saves your life! But if you don’t have an OLED screen, you can still do something to save battery.
Get a powerbank, which can be used to recharge your device several times!
