Samsung's Galaxy S26 lineup comes with a buried feature that can keep your phone running like new for years. Device Care, a built-in optimization suite found on every Galaxy phone, includes an Auto Optimization setting that runs quietly in the background to maintain peak performance. The feature handles memory cleanup, storage management, and battery optimization without requiring much user intervention.

The most useful component is Auto restart, which lets you schedule automatic reboots on specific days and times. Samsung notes this helps keep your phone running in the best condition. Security experts recommend restarting smartphones at least once a week to close background apps consuming resources, address occasional glitches, and even reduce malware risk—something the NSA has specifically highlighted. Some recommend daily restarts for optimal performance.

To enable this, open Settings > Device Care > Auto Optimization > Auto restart, then toggle on Restart on schedule and pick your preferred day and time. You can also enable Restart when needed for automatic reboots when the phone detects performance issues. With Samsung providing up to seven years of software support for its flagships, using these built-in tools helps ensure your device stays optimized throughout its lifespan.
