Download synchronization assistant
First, you need to download and install the Synchronization Assistant tool. You can easily find the download address on the Internet. Next, connect the iPhone6 or Plus to the computer through the data cable. Open the sync assistant, and the tool will automatically recognize your iPhone. The first time you connect, you may need to install the driver, and then you will see the operation interface.
Clear cache
Simply click the "Clean up Garbage" button behind the bottom capacity to start cleaning up the cache. At the next prompt, select Clean Now. The synchronization assistant scans the junk files in the mobile phone and displays the removable cache. You can choose the default recommendation, or you can choose the cleaning content yourself, and then click Start Cleaning.
Important reminder
Important reminder: Apple phones don't need to clean up garbage as frequently as Windows does. The "cache" in IOS refers to the avatar of friends QQ or WeChat, the video of friends circle, etc. These are to speed up the software startup. In addition, you can also handle cookies and records of web pages through the cleaning function that comes with the software.
Storage space management
I hope this information can help you better manage the storage space of iPhone6/Plus. If you have any other questions, please feel free to ask!
