To solve the problem of insufficient storage space on iPhone, it can be achieved by cleaning large files in the information, managing "other" types of data, enabling photo optimization functions, and thoroughly uninstalling applications. First, go to Settings → Information → General → Large Attachments, delete videos, voice and other files that occupy space one by one, and turn off "automatic download"; secondly, clean up "other" data by restarting your phone, clearing Safari cache, reinstalling some apps, etc.; then, turn on "Optimize iPhone storage space" in the photo settings, and save the original image to iCloud to save local space; finally, use the "Uninstall App" function instead of just deleting the icons, completely clear the application and its cached data, thereby effectively freeing up the storage space.

The phone has insufficient storage space, which is really annoying. Especially for iPhone users, there are many system restrictions, and they do not transfer files by simply connecting a USB flash drive like Android. If you want to make some space, it is sometimes not enough to just delete photos and uninstall applications. In fact, as long as you master a few key operations, it will not be so troublesome to clean it up.

Clean up large files in "Information"

Many people don’t realize that there are a bunch of large files that take up space in the “information” application—such as videos, pictures, voice messages sent to you by others, and even iCloud shared content that is automatically downloaded. These things accumulate more and more, and they will secretly eat several GB of space.

You can do this:

• Open Settings → Information → General → Large Accessories, you can see all larger files here
• Click in and delete one by one, especially those videos or long voices that have been useless
• It is recommended to turn off "automatic download" in the settings to prevent it from taking up space in the future.

Although this method looks inconspicuous, it is possible to save dozens of GB once and once.

Manage "other" types of data

In the iPhone storage statistics, there is a data called "other", which often accounts for more than ten to tens of GB. It mainly includes Safari cache, log files, email attachments, temporary system files, etc. These files are not something you can't delete on your own initiative, but there is no way.

You can try these methods:

• Restart the phone: simple and effective, can clear some caches
• Clear the history and website data of Safari browser (Settings → Safari browser → Clear history and website data)
• Delete and reinstall some commonly used apps, such as WeChat and Weibo, which have long-term running and accumulated a large amount of local caches.

This step takes some time, but it is very helpful for overall space optimization.

Take advantage of the Optimized Photos feature

If you open the iCloud photo gallery, don't miss the option "Optimize iPhone storage space". It will allow the phone to save only compressed versions of photos and videos, and the original films are all on iCloud, which can not only see pictures but also do not occupy local space.

Specific opening method:

• Settings → Photos → iCloud Photo Gallery → Select "Optimize iPhone Storage"

If you have been turning off this function for a long time, it is recommended to sync it with Wi-Fi first, otherwise it may be very slow to upload a large number of photos at once.

Uninstall unused apps, rather than just deleting them

iOS has a "Uninstall App" function, which is more thorough than simply deleting it. It not only deletes the application itself, but also clears all caches and data in the app. Ordinary deletion is just an uninstall icon, and the data still occupies space in the background.

How to enable:

• Long press the App icon → Tap "Remove App" → Select "Uninstall App"

Especially some tools and apps that are only used once a while, after uninstalling, you will find that a lot of hidden data has been cleared.

Basically these are the methods. It is not difficult to say, but there are indeed many things that are easily overlooked. The key is to check it regularly and don’t let the junk files pile up more and more.
