Method 2. Delete and Reinstall App (Complete Data Reset)

Step 1.

Part 2. How to Clear App Data on Your iPhone from Settings

If you want more control over application data and cache, you can manage them directly through your iPhone settings. This method is ideal for users who need to free up iPhone storage without losing important documents or app data. By using the iOS reset app data features, you have the possibility to update apps and save up storage.

Steps to Clear App Data via Settings

Step 1.

Go to Settings and find General, then tap on iPhone Storage.

Step 2.

Find the app you want to offload and tap it. Tap Offload App. This removes the app but keeps its documents and data.

Step 3.

Get the app back on your device from the App Store. Your app is new, yet your data is still there, if the app allows it.

Offload App vs Delete App Tips

Offload App: It just takes the app off your device, but keeps the documents and data. Perfect for the apps that you might reinstall later. It saves storage without losing your preferences.
Delete App: It totally deletes the app along with all its data. This is the right way if you want to start fresh or if you really need to get a lot of storage space free.
