Updating iOS

Hello Davey17,

We would like to see how we can help you with updating your iPhone. If there isn't enough space to download and install an update, the software on your device will try to make space. It will remove only app data that it can download again and doesn't remove or relocate any of your data. If your device still doesn't have enough space, you can use your computer with the steps from this link: If you need more space for an update on your iPhone, iPad, or iPod touch - Apple Support

"Use your computer to update your iPhone, iPad, or iPod touch

2. Plug your device into your computer.
3. Locate your device on your computer. You might need to trust your device to continue.
4. Click Check for Update.

5.Click Download and Update."

Cheers!
