Sometimes, a phone slows down because its storage is full, so delete unnecessary files.
Background apps use a lot of RAM, so close the apps you don't need from the recent apps section.
Some apps accumulate a lot of cache data, which you can clear in the settings. This also helps speed up your phone.
Restart your phone once or twice a week. You'll see an improvement in performance.
Be sure to check for software updates, as sometimes slow performance or lag issues are fixed through updates.
