Android Oreo feature spotlight: You can force Android’s new background limits on old apps
Android 8.0 Oreo includes several changes to how background processes work, in order to squeeze even more battery life out of your device. One of these is the Background Execution Limit, which imposes new rules on what apps can do in the background. By default, the new limits only apply to apps targeting Android 8.0, but you can force it on older apps as well.
Once you open the App Info panel for a given app and tap Battery usage, there is a new Background activity toggle.
