How Can I Clear System Data on My iPhone?
You might be curious about how to erase System Data now that you are aware of how to check the space it takes up on your iPhone. Because system data on an iPhone includes a variety of items, including temp files, logs, website caches, system files, and streaming media caches, there isn’t a simple method to remove it. But, there are numerous techniques to reduce the system data to less than 1 or 2 GB. Let’s look at how to clear the iPhone’s system data.
#1- Offload Unused Applications and Clear the App Cache
A large amount of cached data may impede the performance of the iPhone and cause difficulties i.e. freezing, occasional crashing, etc., thus clearing the app cache on the iPhone every few months is crucial to free up storage space and fix speed problems.
Fortunately, some apps give in-app settings where you may clear the cache. For example, in Snapchat, one can clear the cache data to free up space on your device. This is how you do it:
- Go to your Profile > Settings icon > Clear Data > Clear Cache > Cache in the Snapchat app on your iPhone.

Offloading the unwanted apps could help if you can’t free up enough space on your iPhone. The unneeded apps will be removed from your iPhone after offloading, but their files and data will remain. Here’s how to manually unload an app on an iPhone in order to remove system data:
- Go to Settings > General > iPhone Storage on your iPhone.
- To confirm your choice, choose any app, press Offload App, and then select Offload App once more.

#2- Delete Website Data and Browsing History
Clearing iPhone browser history and website data is another simple method for deleting system data. Your browser keeps a lot of cache data on your device as you visit the internet, including URLs, automatically populated user names and passwords, etc. This kept browsing data making it simple to access regularly visited websites quickly in the future. But, you shouldn’t keep the cache data around for too long because it’ll clog up the browser and slow down your device.
This is why it’s important to frequently clear the browser cache in Safari, Google Chrome, and Mozilla Firefox to keep them organized and speedy.
#3- Get Rid of Big Message Attachments
In order to prevent them from taking up additional space on your iPhone, it is a good idea to delete mail attachments that are outdated or no longer required. Here’s how to handle the attachments in your iMessages:
- On the iPhone, select the Messages app by going to Settings > General > iPhone Storage and then scrolling down.
- To view photos that have been sent via iMessage, select Photos.
- Now choose the image you want to remove by tapping Edit in the upper-right corner.
- Your attachments are erased when you tap the Trash can icon.

Important Note- While erasing the system data, you might unintentionally clean crucial data from your iPhone. In this situation, utilize an expert iPhone Data Recovery Tool to retrieve any deleted attachments, including images, videos, and GIFs. This software makes it simple to retrieve lost or deleted iPhone contacts, calendars, videos, audio, and other data.
To review attachments you no longer require, touch on Videos, GIFs, and stickers.
