Apple offers 5 GB of free iCloud space to everyone, but you’ll run up against that storage limit sooner than you’d think. Device backups, photos, documents, iCloud email, and other bits of data all share that space.

If you have multiple iOS devices, you’ll run out even faster. That free 5 GB is per Apple ID, not per device, so it’s a good idea to free up wasted space before paying for more.

To see how much you currently have, open the Settings app, select “iCloud”, and find where it says “Storage” to view how much space you have left in your iCloud account.

You can also view your available iCloud storage space by navigating to “General” > “Storage & iCloud Usage”.

If things are starting to get low, here are a few things you can do.

Manage Your Backups

Each iPhone or iPad you own automatically backs up data from your installed apps to your iCloud account. This happens when it’s plugged in, locked, and connected to Wi-Fi—so it will generally back up whenever you’re charging it. This ensures you’ll never lose your app data. If your device dies or you need to reset it, you can restore the backup and get all of that data back. However, you’ll still need to back up your device through iTunes in order to back up the apps themselves, as well as music, videos, and other media.
