What is Device Care and how do I use it?

Please note: Battery and device care is the optimisation app for devices running Android 11. If your device is running Android 9.0 and 10.0, it will be called Device care. On Android Oreo or Nougat your optimisation app will be named Device maintenance and function in a similar way to Device care. If your device is running Android Marshmallow or below you can optimise performance with Smart manager.

Battery and device care gives you all the tools you need to keep your device running smoothly, automatically optimising your battery, storage, memory and security. When you open Battery and device care, your phone will run a diagnostic check and give you a score out of 100. The higher your score is, the better optimised your device is.

Where is Battery and device care?

By default, there isn't an app icon for Battery and device care. Instead, it can be found by going to Settings Battery and device care

Optimising your device

Optimising your device ensures that it is operating on top form at all times. Optimisation scans your device to determine what is using your battery, how your storage is looking, what is using the most memory and if there are any threats on your device. Optimisation happens automatically once a day but can also be started manually.
