Android Oreo has done a bang-up deal to help preclude excessive bombardment drain. With a brand new API geared toward limiting background usage, apps can no longer run abroad and bleed your battery. Still for this to work, an app developer must have employed the new API. Since non every app developer has followed conform with that, is it even possible to prevent those older, non-complying apps from wasting precious bombardment? Fortunately, the answer to that question is a resounding aye.

I want to testify you how to disable groundwork activity for those misbehaving apps. Practise understand this comes with a caveat: Those apps that yous disable the background activity for might not function as expected. Notifications can exist delayed and other odd beliefs might announced. Withal, if battery life has become an issue with a must-have app (one that doesn't take advantage of the new Oreo API level), this might be your only selection until the developer rebuilds their app to meet the Oreo standards.

With that caveat out in the open up, let'due south meet how to disable background activeness in an app that is pummeling your battery.

Disabling background action

To disable background activeness for an app, open up Settings and go to Apps & Notifications. Within that screen, tap on See all Ten apps (where X is the number of apps you have installed – Figure A).

Figure A

Once you've tapped the offending app, tap the Battery entry. In the resulting screen (Effigy B), tap the On/Off slider to disable background activity.

Figure B

Congratulations, that app volition be prevented from working in the background–thereby non draining your battery. The just time that app will piece of work is when it's open. Close the app and action will cease.

Enable background activeness

The next fourth dimension that offending app gets an update, I would recommend going back and enabling background activity. To do that, simply opposite the process outlined to a higher place. If you find the app is no longer gobbling up your bombardment, get out groundwork activity enabled. If the app goes dorsum to draining the battery, disable background activity. Echo this until the programmer finally rebuilds the app with the new API and your bombardment is safe from drainage.

Not perfect

In a perfect world, all app developers will be using the new API. Since we're not existing in a perfect world, in that location volition be apps that might continue to drain the battery on your Android device. If you discover that happening, you now have the power at your fingertips to finish this unwanted activity.
