How to free up space on iphone quickly when phone storage is full?

Safari stores browsing history, cache, cookies, and offline reading list items that count toward System Data. Clearing these can free up space on iPhone quickly. This can help reduce the amount of storage used by Safari, especially if you've visited many websites or have accumulated a lot of cache over time.

How to do it:

1. Go to Settings > General > iPhone Storage

2. Scroll down and tap on Safari

3. Tap Website Data

4. Tap Remove All Website Data

Also check Offline Reading List:

In the same Safari storage menu, swipe left on Offline Reading List and tap Delete

Remember, clearing website data may log you out of some websites and remove preferences, but it’s a quick and effective method to free up space on iPhone quickly. If you're looking for ways to optimize your device storage efficiently, this is definitely one of the steps to consider.
