Powering one single color can double your Android's battery life

Powering one single color can double your Android's battery life
Powering up just one color channel on your Android device's organic LED display can help save your battery life. Android engineer Jeff Sharkey was able to hack his phone to allow for one color channel to be powered at a time. Using an industrial power meter, he was able to determine which color saved the most battery power. It turns out, red is the color that helps you extend your battery life the most. He said, "Filtering to show only red pixels only requires 35% of the original baseline OLED panel current, on average. Adding back the baseline current, the best case overall is about 42% of the original system current, effectively doubling the battery life. Also, showing only red pixels doubles as an awesome night vision mode, perfect for astronomy." For more information on Jeff's experiment, check out the source link.

That is not funny jpropin. Cell phone of today are like tiny computers. If you go to one color only, you will strain your eyes and make you eye sight worse. Look to the generation that used the original computers with the black and white screen. They have glasses on now.

Its not worth it. I have a charger at home, a car charger, and a charger at work. Honestly just buy a couple chargers and you'll never have to worry about having your phone die. Or you can even buy another battery....well unless you have the iphone.

You mean "said?" Maybe get your spelling right first?

Just spit-balling, but maybe the manufacturers could just equip their products with better batteries. That might be a good point to start.
