How to keep your Galaxy phone from slowing down

Galaxy Note10+ with Device care screen

To keep up with the nuts and bolts of your phone's performance, use the Device care feature. It provides an overview of your battery, storage, RAM, and security. You can also automatically optimize your phone for faster, better performance.

Note: Available screens and settings may vary by wireless service provider, software version, and phone model. This feature was previously called Device maintenance.

Quick optimization

The Quick Optimization feature improves your phone's performance by identifying apps that use excessive battery power. It also clears away unneeded items from memory, deletes unnecessary files, 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.
