How to keep your Galaxy phone or tablet from slowing down

The Quick optimization feature improves your device's performance by identifying apps that use excessive battery power. It also clears away unneeded items from memory, deletes unnecessary files, scans for malware, and closes apps running in the background. Optimizing your phone is quick and simple.

From Settings, swipe to and tap Device care. Tap Optimize now, and then tap Done.

If you know you'll be away from a charger for an extended period and you want to make sure your device will last, just turn on Power saving mode. This way, you won’t have to worry about a low battery.

First, navigate to Settings, and then tap Device care. Tap Battery, and then tap Power saving. Tap the switch to turn it on. This will limit certain things on your device, such as background network usage and syncing.

You can use additional power saving options as well:

By default, your phone uses a Standard performance profile that balances processing speed, battery life, and cooling efficiency. However, you can change this to Light mode, which prioritizes battery life over processing speed.

Is your device getting glitchy and slow? Clean up your device's memory to improve its performance.

From Settings, swipe to and tap Device care. Tap Memory, and then tap Clean now to free up memory by stopping background apps. If you'd like to keep certain apps running in the background, you can tap Excluded apps and add your preferred apps to the list so they do not get closed when you use this feature.

From Battery and device care, tap RAM Plus, and make sure the switch is turned on. Then, tap the amount of GB you'd like to allow, and tap Restart when prompted to restart your phone with your desired setting in place.

Inactive apps will be moved to virtual memory, so that more RAM is available to the apps you are currently using.
