In most versions of Android, hit Settings > Device > Battery or Settings > Power > Battery Use to see a list of all apps and how much battery power they're using. (In Android 9, it’s Settings > Battery > More > Battery Usage.) If an app you don't use often seems to take up a disproportionate amount of power, consider uninstalling it.

In Android 9, you can see how power-hungry apps as using battery by tapping it. For some apps, you'll be able to turn on "Background restriction." For all apps, keep "Battery optimization" on.
