• Doze reduces battery usage when your device is not in use, not
charging, and not moving.
• App Standby lets Android reduce battery-draining activities of apps
that you haven't used for a long period of time (when your device isn't
charging).
Doze and App Standby do not have separate settings. They are two
of several battery optimizations that are in effect by default in most
situations. However, you can stop all battery optimizations for an
individual app, for example to ensure that it's always functioning at peak
performance, even when you're not using it.
