What is Device care and how do I use it?

Video Alternative Text

Please note: Device care is the optimisation app for devices running Android Pie and higher. If your device is running 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

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 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 Device care?

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

Where can I find Device care?

Optimising your device

Optimising your device ensures that it is operating in 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.

Battery

The battery is the beating heart of your device, giving you the power you need to use your favourite apps. When optimising the battery, Device care will close any apps that are draining your battery in the background. Through Device care you can change the power mode, check your battery usage and customise a range of power management features.

There are a number of power modes available on your device. Each mode balances the performance of your phone with the battery used, with higher performance modes using more battery than lower performance modes.

Memory

The memory on your device quickly loads all of the information about the app or game you are using. If your device is close to using all of it's available memory you may find that your device slows down or apps don't function as they should.
