If you're experiencing lagging and battery draining issues with your Samsung M21 smartphone, there are several steps you can take to try and resolve these problems:

Restart your device: A simple restart can often resolve temporary performance issues. Press and hold the power button, then select "Restart" from the options that appear.

Check for software updates: Make sure your device is running the latest software version. Manufacturers often release updates that include bug fixes and performance improvements. Go to Settings > Software Update and check for any available updates.

Clear app cache: Cached data can sometimes slow down your device. To clear the cache for specific apps, go to Settings > Apps, select the app causing issues, and choose the "Clear cache" option.
