University researchers create app to extend Android battery life by up to 25 percent

Researchers at the University of Waterloo have figured out a way for Android multitaskers to get 25 percent more time out of a battery charge, though the particular scenario that takes advantage of this isn't a common one. And as Engadget reports, this battery saving has a few caveats.

If you're one of the chosen few to have Android 9 Pie running on your phone right now, then you have split-screen support, which is where Waterloo's "MultiDroid" app comes into play, although it has yet to be released to the public. In a nutshell, the app works by dimming the side of the screen that you're not interacting with at that moment.

As any mobile geek can tell you, simply having the screen on will be one of the biggest drains on your battery, second only to rendering 3D or VR, which remains challenging even for desktop and laptop PCs. According to the university, being able to selectively dim areas of the screen can extend your battery charge by 10 to 25 percent.

Note: This battery-saving technique only works with OLED screens, which are customarily reserved for expensive phone models.

But what are the odds that you'll get Android Pie?

While Android 9 is currently only available on Google's Pixel phones and the Essential PH-1, dozens of other devices are scheduled to be updated. Motorola currently leads the pack with eight, Sony is purportedly readying six phones, and Samsung has committed to Pie updates for its high-end models like the Galaxy S9 and Note 9.

Despite Google's recent inroads with Motorola and Sony, it continues to struggle overall with getting manufacturers and mobile network carriers to update older phones and launch new devices with the latest version of their operating system.

Android Oreo took eight months to come to the Galaxy Note 8, and one year to come to the Galaxy S8. Samsung has not committed to release dates for Android Pie updates on any of their devices. The Galaxy Note 9 came out earlier this month sporting 8.1 Oreo, just as 9.0 Pie was reaching store shelves.

According to Google's own statistics, only 12 percent of their phones are running Android Oreo, which came out last year; 30 percent of phones are still on the version before that, and 24 percent are still on Marshmallow, which was released to the general public nearly three years ago.

For reference, Apple states that over 80 percent of its users are on iOS 11, and only 14 percent remain on iOS 10. (iOS 12 is currently available in a public beta; a final version is expected next month.) Granted, Apple has far fewer devices to deal with, and it makes a lot of its own chips, so it's much less reliant on third parties for software updates. But the contrast remains stark.

In Summary:
Researchers at the University of Waterloo have designed an app that can extend your battery charge by up to 25 percent, although it currently only works with Android Pie and OLED screens.
Only a small handful of phones are currently running Android Pie, as Google continues to struggle with getting manufacturers and mobile network carriers to update older phones and launch new devices with the latest version of their operating system.
