What battery optimisation is on Android

Why it matters

Doze puts the phone to sleep once it lies still with the screen off, and standby buckets since Android 9 cut background work for apps you rarely open. An exemption lifts both.

Where it is in settings

Stock Android (Pixel, Motorola), Samsung

Settings → Apps → your app → Battery → Unrestricted.

Xiaomi, Redmi, POCO

Settings → Apps → Manage apps → your app → Battery saver → No restrictions.

Huawei, Honor

Search the settings for battery optimisation, find your app and set it to not be optimised. In the MagicOS 10 guide that name belongs to a different screen with an OPTIMIZE button; if the search lands there, it is not the right place.

OPPO, realme

Settings → Battery → App battery management → your app → turn on Allow background activity, Allow foreground activity and Allow auto launch.

OnePlus

Settings → Battery → Battery optimisation → All apps → your app → Don’t optimise. If there is no such screen, open the app’s own battery page and allow background activity, as on OPPO.

vivo, iQOO

Settings → Battery → High background power consumption → turn it on for your app. On newer versions the item is called "Background power consumption management": pick "Don't restrict background power usage" for the app, or "Unlimited" on iQOO.

Tecno, Infinix

Settings → App management → App list → your app → Battery → allow running in the background. On the same app screen, turn off stopping the app when idle.
