Breaking down storage information

Visit Settings

Go to Settings > General > iPhone/iPad Storage and you’ll see something similar to the image shown above. Be mindful that it can take a short while for the entire page to fully load.

Break it down

At the top of the page, you’ll see your device’s maximum storage, and what types of media are currently eating up space. This feedback gives you a good starting point when it comes to pruning.

Offload apps

As of iOS 11, your iOS device can automatically offload apps and games when storage is low. This can free up space, and you don’t lose anything — simply tap an app’s Home screen icon to redownload it; its docs and data will still be present.

Use iCloud

iOS unsurprisingly suggests using iCloud Photo Library if you’re not already doing so. Note that you may need to pay for additional iCloud storage space to use this.

Review media

If it’s present, tap Show All to see additional suggestions for videos and attachments, both of which can take up a lot of space. In all cases, you can preview individual items before deleting them.

Examine apps

Scroll down for a list of all the apps and games installed on your device, with those taking up the most room at the top, and the date you last used each. You can delete or offload apps manually, if you want. You can always redownload apps later, but deleting will trash their data.
