However, multiple ways exist to bring the system data down to less than 1 or 2 GB.
Let’s see how to clear System Data on iPhone.
1. Clear App Cache and Offload Unused Apps
Clearing the app cache in iPhone every few months is important to free up storage space and fix speed issues because a huge pile of cached data may hinder the iPhone’s performance and create problems like freezing, random crashing, etc.
Fortunately, you can delete the cache from the in-app settings for some apps. For example, in Snapchat, you can delete the cache data to save space on your device. Here’s how to do it:

2. Clear Browsing History and Website Data
Another easy way to delete system data is by clearing iPhone browsing history and website data. As you surf the web, your browser stores many cache data, like URLs, auto-filled names and passwords, etc., on your device. This saved browsing data make it easy to access frequently-visited websites quickly in the future. However, you shouldn’t keep the cache data for too long as it will clutter the web browser and affect the device’s performance.
This is why browser cache in Safari, Google Chrome, and Mozilla Firefox browsers should be cleaned regularly to ensure your browser is clutter-free and running smoothly.
