  What should I do if the capacity is not 1, 9 GB?

For users with insufficient capacity, you need to properly clean up the phone memory. Below are five methods to clean up the Apple space memory.

  1. Disable permanent storage of text messages

By default, your iPhone will permanently save all sent and received text messages. This feature is useful if you want to view the conversation about 15 months ago, but if you want to have enough body space, you 'd better disable it.

Go to "Settings", click "information", slide down, and click "retain information" in "Information History ", change the default "permanent" to "30 Days" or "1 year ". A prompt is displayed, asking if you want to delete the old information. Click "delete.

  2. Do not save the photo twice.

If you often use the iPhone's HDR photo mode or Instagram, you will find that these photos are saved twice: the HDR version (or the Instagram filter version) and the normal version.

So how do I disable HDR photo backup? You can first select "Settings"-"photos and cameras" and slide down to disable the "retain normal photos" function.

At the same time, you can open the Instagram app, click personal information, click the "Settings" icon in the upper-right corner of the page, and disable the "Save original photos" function in "settings.

  3. Clear browser cache

If you often use Safari, your iPhone may save a lot of Web page history and browsing data. You can click "Clear History and Website Data" in "settings"-"Safari" to clear the content.

If you are using Chrome, you can find "history" in the menu bar in the upper right corner of the application, slide to the bottom of the page, and click "clean" to complete this operation.

  4. Clear offline data

When using those online applications, you may accidentally store a lot of offline content. For example, Safari will automatically save some content for offline use when you browse online. However, this will only occupy unnecessary space. You can choose "Settings"> "general"> "usage"> "manage bucket"> "Safari" and click "offline reading list" to delete the data.

Music apps like Spotify also save the most recent playlist. You can open Spotify, find the playlist that you do not want to go offline, and disable the offline function. In addition, at the top of the playlist, you can find a function to switch to offline availability. Click close.

5. Selectively delete applications and data

The tips above can only release some space for your mobile phone, but if you want a larger capacity, you need to delete some more "real" content, the content includes apps, videos, photos, blogs, and music on mobile phones. You can view it in "settings"-"general"-"usage"-"Manage Storage Space.

On the "rankings" page, you can find out what occupies the largest mobile phone space. If it is a large game, you can choose to delete it; if it is a photo, you need to consider exporting some photos; if it is music, you 'd better delete some albums and songs.
