Short answer: delete large videos on iPhone by reviewing the heaviest clips first, not by deleting random ordinary photos and hoping storage improves. Large videos often create the fastest visible space recovery because a few files can outweigh a whole batch of images.
That is why large-video cleanup deserves its own pass. Videos usually carry more value than screenshots but much more storage weight than everyday photos. A useful cleanup flow helps you see the biggest storage blocks first, decide what still matters, and create room without combing through the whole library blindly.
What to do first
Identify the heaviest clips before deleting smaller media.
Review old screen recordings, exported edits, and saved chat videos first because they are often low-value heavy files.
Keep anything unclear for a second pass rather than deleting under pressure.
After heavy videos are reduced, move into duplicates and screenshots if more storage is still needed.
Why video cleanup is different from normal photo cleanup
Each file is heavier, so a few decisions can create a big result.
Videos often hide in chat saves, exports, and old recordings.
The emotional value is mixed: some clips matter a lot, some are easy wins.
Manual review gets slow fast when heavy clips are spread across months.
When an app is faster
An app becomes faster when the video backlog is large enough that finding and reviewing the heaviest clips manually starts wasting time. That is where Cleanor for iPhone helps: large videos are surfaced as a dedicated cleanup pass instead of being buried in the rest of the camera roll.
What people usually ask next
Should I delete videos before photos? Usually yes when storage pressure is urgent, because videos create the biggest visible win first.
What kinds of videos should I review first? Old screen recordings, duplicate clips, chat saves, and exports are usually the easiest heavy wins.
Why is the phone still full after deleting photos? Because the real storage hog may have been large videos all along.

When storage is tight, the smartest delete is usually the heaviest obvious video, not the hundredth ordinary photo.
