Google’s big Android battery ‘oops’ and future Dark Modes



Today Google has revealed some information about how your smartphone spends its battery life. They did it during the Android Dev Summit this week, talking to developers about what they can do in their apps to avoid consuming large amounts of battery. But this is not just about this. This is the most important factor in battery consumption: screen brightness! And not only this, but also the color of the screen!

The information we are looking at today comes from Google during a presentation at the Android Dev Summit of 2018. This is different from Google's I / O, for some reason: it's all based on Android, but also on Chrome and other things. It was Android, this week and the most precious battery time for all users. The duration of the mobile battery, in smartphones, the devices that most people use most of their time.

The first and most obvious information shared by Google concerned the brightness and power of the screen. This should be fairly obvious: more brightness means faster absorption of power. They found that it is not always perfectly linear, but it is so close to the linear that it could also be a straight line, one by one.

Later they shared some information about their studies which, as you will see, I am not made with the most recent hardware we have available today. They did this study with the first Google Pixel. The differences between the first Pixel and the rest are irrelevant here. What is important is the difference between the power consumption at maximum brightness between normal mode and "Night mode". Not all smartphones use this feature.

Google also studied the colors. The color shown on a display really affects the power absorbed by the phone's battery. As you will see in the chart here, each color has a different amount of absorption on the battery of its device.

The following graph shows the main differences between the maximum brightness with a color like black (which has just a power absorption) and white (which has the greatest power of all.) As white it uses all the various components of the display to shine, use maximum power.

The OOPS moment of Google

Google admitted on stage today that they had done a little bit. of an error. Not recently, but in recent years. Since the start of the Google Material Design initiative, they have pushed the use of white color, encouraging designers to use white as the main color for all apps and interfaces.

ABOVE: the slide of Google while explaining the situation with the brightness of the display and the white color. Because they were pushing white as the primary color for all Android (and other systems) software layouts.

Even now, while the event takes place, the "basic material color theme" so as it is in the official information on the Google material the site shows the following Look at everything that is white.

On Primary, Background, Surface and Error on are all white. It's not that they should not be – that only makes sense as a set of default design settings for all designers. But if we are aiming for an ideal drainage, white should not be here in its purest form, #FFFFFF ALL COLOR.

Dark Mode

Fortunately, as Google revealed this week, the proverbial dark mode can make a big difference in how much power they have ALL the apps in Android. Probably Google will continue to release Dark Mode in their apps in the future, as long as we continue to have to recharge the batteries in our phones.

I suppose they will stop when they find that infinite solution of renewable energy that allows our phones to stay active. Keep your fingers crossed for that – even if the dark mode is better for your eyes, in the long run.
