How to Fix "iCloud Storage Is Full" on Your iPhone

If your iPhone has been showing a message that says "iCloud Storage Is Full," it means the free 5 gigabytes Apple gives every account has been used up. When this happens, your phone stops backing itself up to iCloud, your photos may stop syncing, and you might not receive new iMessages on other Apple devices. It sounds alarming, but it is a common and easy problem to fix.

First, check what is using up your storage: Open the Settings app, tap your name at the top, then tap "iCloud." You will see a colorful bar showing what is taking up space — usually backups, photos, and apps are the biggest users. Tap "Manage Account Storage" to see a detailed breakdown. From here you can delete old phone backups (especially from phones you no longer own), turn off iCloud backup for apps you do not care about, and see if there are large files you no longer need.

If you want to add more storage, Apple's iCloud+ plans are affordable: 50 GB costs about $1 per month, and 200 GB costs about $3 per month. To upgrade, go to Settings → your name → iCloud → Manage Account Storage → Change Storage Plan. You can also choose to keep photos on your phone and computer instead of iCloud by turning off "iCloud Photos" and backing up photos manually. However, for most people, upgrading to 50 GB for $1 per month is the easiest solution — it typically lasts for years before needing to increase again.
