The Ipad can't be set not to update the system automatically, but when the iPad has a system update, the iPad will automatically download the latest version of iOS, but it doesn't want to update. We can stop the system update by deleting system files. So how do you delete system files?

1. Open the settings on the iPad first.

2. Then click General.

3. Then choose the dosage

4. You can see how much memory there is at present, and click Manage Storage Space.

5. You can see the installation package, which takes up a lot of space

6. Click to enter, you can see the delete update, and click Delete.

If you want to upgrade in the future, you can download it in the software update.

7. Space is back. Generally, after manually deleting the installation package, the update will not be downloaded automatically.
