The iOS operating system is highly praised for its ability to manage storage efficiently and release minimal 'junk' storage compared to the Android operating system. However, with prolonged use and continuous software updates, the virtual storage on the iPhone tends to increase, requiring us to free up memory to avoid memory overflow issues.

1. Clear Safari Cache and Browsing History
Step 1: Go to Settings (1) => Safari (2).

Step 2: Choose Clear History and Website Data (1) => Clear History and Data (2).

2. Delete and Reinstall Apps with Large Documents & Data.
Step 1: Go to Settings => General Settings (1) => iPhone Storage (2).

Step 2: Find and select apps with large document storage. Typically, social media apps like Facebook, Messenger, Zalo, or those with extensive data storage are the ones to target. Let's take Zalo (1) as an example, then press Delete App (2) to clear all data associated with that app.

Step 3: Then open the App Store and reinstall the app you just deleted. Next, reopen the iPhone Storage section and check if the app's storage has decreased as shown below, indicating success.

3. Utilize a Trick to Free Up Memory on iTunes Store
This trick essentially involves a temporary memory cleanup feature to prevent memory overflow on iPhone. The execution method is quite simple.

Step 2: Click on 49.000đ RENT (1), wait for the Unable to Download notification to appear then click on Settings (2).

Then you'll be taken to the General Settings section. Next, tap on the About section and observe the iPhone storage has been freed up slightly from 41 MB to 168 MB. Repeat this process multiple times until the memory on iPhone stops increasing.
With this method, your device can free up several GBs of memory if your virtual memory is too high.
