Phone Cleaner is the on-device iPhone cleaner — now made for iPhone Duo.See what's new

1. See what is using iCloud

Settings › your name › iCloud shows a bar with Photos, Backups, Messages, Documents and Mail. Tap Storage — called Manage Account Storage on some iOS versions — for the list, biggest first.

2. Make the photo library smaller

With iCloud Photos on, every photo and video counts against iCloud. Deleting duplicates and compressing big videos on your iPhone shrinks the library everywhere, because the changes sync.

3. Remove old backups

  1. Open Settings › your name › iCloud › Storage › Backups.
  2. Tap a device you no longer use.
  3. Tap Turn Off and Delete from iCloud, and confirm.

4. Clear iCloud Drive and attachments

In the Files app, browse iCloud Drive and sort by size. In Messages, Settings › Apps › Messages › Keep Messages set to 1 Year stops old attachments piling up.

Questions

Does deleting from iCloud delete from my iPhone?

With iCloud Photos on, yes — the library is the same on every device.

Why is my iCloud full when my iPhone isn't?

iCloud also holds backups and files from your other devices.

Is compressing a video the same as deleting it?

No. You keep the video, smaller; with Keep originals on, the original stays too until you remove it.
