How to Close Apps Draining the Battery on a Huawei Ascend

By Fred Decker

Battery life is the mobile-device equivalent of gas mileage, and like mileage, your actual results can be frustratingly different from the estimates you'll find in sales brochures. It's especially difficult if you're new to Android, and haven't yet mastered the art of app management. Fortunately, the basics are the same across all Android phones even though their customized interfaces can differ. For example, if you own one of Huawei's popular Ascend series phones, you'll use that company's Emotion interface to start and run apps. To stop them, you'll still use Android's "Recent Apps" button.

The Basic Process

At the bottom of any Android phone's screen are three "soft buttons" that provide basic controls. The one at the bottom right is your Recent Apps button, which -- if pressed -- brings up a screen showing all the apps you presently have running. You can switch to a given app by tapping it, which is convenient, but that convenience comes at a price. The more apps you have running, the shorter your battery life. To close the apps you no longer need, simply place a fingertip beside that program's listing and swipe your finger from left to right. The app will close and disappear from your listing.

The Worst Offenders

Some apps drain your battery more aggressively than others, typically because they check frequently for updates. A 2014 study by antivirus company AVG found that Facebook's Android app was the worst offender, with other social apps such as Path, Instagram and Blackberry's BBM messaging service close behind. Any apps using Bluetooth connectivity or your phone's GPS circuitry will also drain the battery, because those chipsets are notoriously power-hungry.
