Device maintenance
The device maintenance feature provides an overview of the status of your device’s battery, storage, memory, and system security. You can also automatically optimise the device with a tap of your finger.
Using the quick optimisation feature
On the Settings screen, tap Device maintenance →FIX NOW or OPTIMISE NOW.
The quick optimisation feature improves device performance through the following actions.
• Clearing some memory.
• Deleting unnecessary files and 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 activating power saving features.
On the Settings screen, tap Device maintenance →Battery.
• The usage time left shows the time remaining before the battery power runs out. Usage time left may vary depending on your device settings and operating conditions.
• You may not receive notifications from some apps that use power saving mode.
Power saving mode
• MID: Activate power saving mode to extend the battery’s usage time.
• MAX: In maximum power saving mode, the device decreases battery consumption by applying the dark theme and limiting the apps and features available. Network connections, except for the mobile network, will be deactivated.
Managing the battery
You can save battery power by preventing apps that are running in the background from using battery power when they are not being used. Tick apps from the apps list and tap SAVE POWER. Also, tap →Advanced settings and set the App power monitoroptions.
Storage
Check the status of the used and available memory.
On the Settings screen, tap Device maintenance →Storage.
• The actual available capacity of the internal memory is less than the specified capacity because the operating system and default apps occupy part of the memory. The available capacity may change when you update the device.
• You can view the available capacity of the internal memory in the Specification section for your device on the Samsung website.
Managing the memory
To delete residual files, such as cache, tap CLEAN NOW. To delete files or uninstall apps that you do not use any more, select a category under USER DATA. Then, tick items to select and tap DELETE or UNINSTALL.
Memory
On the Settings screen, tap Device maintenance →Memory.
To speed up your device by stopping apps running in the background, tick apps from the apps list, and tap CLEAN NOW.
Device security
Check the device’s security status. This feature scans your device for malware.
On the Settings screen, tap Device maintenance →Device security → SCAN PHONE.
