Have you ever received the dreaded message "iPhone cannot be synced because there is not enough free space to hold all of the items in the iTunes Library (additional space required)"?
We're not surprised. Our smartphones are the center of our digital universe, and they hold lots of data: text messages, photos, browsing history, etc. If your iPhone's storage is at capacity, then follow these simple steps to make room for more data.
Identify What's Taking Up the Most Space
Find out what your problem areas are before deciding what to delete. On the iPhone, head to Settings > General > Usage to view how many gigabytes you have available. Apps will be listed by how much storage they occupy - Photos & Camera is likely to be at the top of this list. From the Usage menu, you can tap on an app's name to delete it.
On a Mac or PC, plug the iPhone into a computer and open iTunes to view storage broken down by Audio, Photos, Apps, Books/TV Shows/Movies, and Other. Hover over one of these categories with your mouse to view details. "Other" represents settings, calendar events, notes, browser cache, email, email attachments, and more nonmedia data.
If Other makes up an overwhelming amount of iPhone storage, then there may be an issue with corrupted data. If you've tried deleting all of our suggestions and there is still lots of Other storage, then consider restoring your iPhone. Make sure you have the latest version of iTunes, have backed up the device, and have synced content with your computer. Connect the iPhone to your computer, and in the Summary tab, click on Restore iPhone. This returns the iPhone back to factory settings.
