3.20 Battery and device care

Introduction: Galaxy S23 device care feature provides an overview of the status of your device’s battery, storage, memory, and system security. You can also optimise the device and enable the maintenance mode.

After you update your Galaxy S23 to Android 14 (One UI 6), Battery and Device Care now are separated into 2 sections in the Galaxy S23 Settings.

Optimising your device

On the Settings screen, tap Battery and device care → Optimise now.

The quick optimisation feature improves device performance through the following actions.

  • Closing apps running in the background.
  • Managing abnormal battery usage.
  • Scanning for crashed apps and malware.

Battery

Check the remaining battery power and time to use the device. For devices with low battery levels, conserve battery power by turning on power saving features.

You can also quickly check battery level with the battery level status icon.

On the Settings screen, tap Battery and device care → Battery.

  • Power saving: Turn on power saving mode to extend the battery’s usage time.
