3. Scroll down to the list of installed apps and review which ones you don't use frequently. Tap on an app and select "Offload App." This will remove the app from your device while keeping its data intact. You can always reinstall the app later if needed.
4. Go through the list of apps and delete the ones you no longer need. To delete an app, tap on it and select "Delete App." Additionally, you can delete other types of data such as photos, videos, messages, and unused files to free up space.
