No Sufficient Space For Download iOS 13/12, How Comes?

By Lois Green, Wednesday, September 25, 2019

Updated on Wednesday, September 25, 2019

When you try to update to iOS 13 wirelessly, a message comes up reminding you that there is no sufficient space on your iPhone, iPad, or iPod touch for downloading iOS 13. In some cases, even though iPhone says there is no enough space, actually there is.

Actually, the public version of iOS 13 takes around 2.2GB, while you also need at least another 2GB free space for the installation to go smoothly. Therefore, you'll need at least about 5GB free storage space on your iPhone/iPad to have iOS 13 installed smoothly. If your iDevice is lack of enough space, try to free up the storage with the following methods.

iOS 10 Insufficient Space


Remove unused apps

Open your iOS device, tap "Settings" > "General" > "Storage" >  to check the internal storage on the device. You can see how much space has been used and select any app to see how much space it uses. For those apps that you barely use, click "Delete App" to remove it to free up iPhone storage space. However, build-in apps on iOS, such as Music and Videos, is undeletable and you can only delete parts of their documents and data.

Optimize iPhone Storage on iOS 11 or Above

If your iPhone/iPad runs on iOS 11, iOS 12, you can get iPhone storage optimization suggestions on Settings > General > Storage. Follow the recommendations to empty the Recently deleted album, move photos to iCloud Photos Library and more to get more free space on your iPhone for iOS 13 update.

Free up Space for Update by Recommendations


Reduce Media Files

There must be videos, photos, or audio files that you don't need on the device. For example, the movies that you have watched, the photos that are not well taken, the podcast files that you will never listen again. For these unnecessary files, delete them to solve the insufficient storage problem. Take photos for example. Open the Photos app, review your photos library and delete those you don't need. 


Compress Videos to Smaller Size

Video files make up of a large part of internal space. So you can free up space for iOS update by compressing videos to a smaller size. This can be done by various video compress tools, which allows you to compress videos directly on iOS devices. For example, Video Compressor, Video Shrinker. Go to App store on your device, install one video compress software, and start to compress large video files.


Delete Files in Bulk

Media files occupy a considerable amount of storage space. Deleting unused media files can easily make space for the iOS 13 download. However, it is inconvenient to delete media file one by one on the iPhone/iPad/iPod touch as it is mentioned above. You can use a powerful tool, FonePaw iOS Transfer, to delete media files in bulk.

The software displays all media files on your iOS device in one place so that you don't have to go to different apps to find the files. You can just choose the file type, find the files, and click "Delete". Moreover, it allows you to transfer iPhone/iPad/iPod touch files to Mac/PC so that you can save the files as well as free up space on your iOS device.

iOS Transfer

Step 1. Download Mac/Window version of FonePaw iOS Transfer on your computer.

Step 3. Choose "Media" on the left column, you can see different types of media files displayed on the right. Choose "Movies", for example, you can then see the list of movies on your device. Tick the movies you want to remove and click "Delete". If you would like to transfer the files to the computer, click "Export to".
