The gigabytes
Large videos are where the space is
A camera roll is mostly photos by count and mostly video by size. If your phone is full, forty videos is a bigger win than four thousand screenshots.
The arithmetic
Modern phones record enormous files, and the defaults are set for quality rather than for how much room you have left.
- 4K at 60 frames per second is roughly 400 MB per minute.
- 4K at 30 fps is roughly 170 MB per minute.
- 1080p at 30 fps is roughly 65 MB per minute.
- A still photo from the same camera is around 2 to 5 MB.
So one three-minute 4K clip is about the same as three hundred photographs. Which means the video you took of a concert, that you have never rewatched, that is mostly other people’s raised arms, is worth more space than the entire year of screenshots you were about to spend an evening on.
Slow-motion is worse again: it records at a high frame rate and then plays back slowly, so a ten-second slow-motion clip holds far more frames than ten seconds implies.
Finding the big ones
Neither platform makes “sort my library by file size” easy, which is a genuine gap.
iPhone
Photos › Albums › Media Types › Videos gathers every video, but in date order rather than by size.
Settings › General › iPhone Storage tells you what Photos occupies in total but does not break it down per item.
Opening a video and swiping up on it shows its size and resolution, one at a time.
Android
Google Photos has a Videos category under Library, again in date order.
Some manufacturer galleries and file managers can sort a folder by size, which is the closest thing to a native answer.
Google One’s storage manager surfaces large videos, but only ones that are backed up to your account.
Time To Swipe filters the deck to videos and shows each one’s size and duration on the card, so the decision is made with the number visible rather than guessed at. A 148 MB card and a 3 MB card look identical in a thumbnail grid, and they are not remotely the same decision.
Reviewing video is a different job
Photos can be judged at a glance. Video cannot, and pretending otherwise is how people delete something they wanted.
What actually helps is knowing the categories of video that are almost always disposable, because you can decide about those without watching them:
- Accidental recordings. A few seconds of a pocket, a floor, or a ceiling. Usually obvious from the thumbnail and the duration.
- Duplicate takes. Three attempts at the same thing where you kept all three and only ever needed the last one.
- Long static shots of a stage or a screen from too far away. The ones where you already know you have never rewatched it.
- Screen recordings. Same logic as screenshots — made for a specific purpose that has since concluded.
- Slow-motion experiments from the week you discovered slow-motion.
For everything else, watch the first two seconds. That is nearly always enough to know what it is, and it is much faster than it sounds when you are only doing that.
Before you delete a video, two checks
Video is the one category where deletion regret is real, because a video is usually unrepeatable in a way that the ninth photo of the same sunset is not.
- Check whether it is backed up. If iCloud Photos or Google Photos backup is on, deleting on the phone deletes it from the cloud too — a synced library is not a backup against your own deletions.
- For anything irreplaceable — a child, a wedding, someone who has died — copy it somewhere else before the cleanup, not during it. A separate external drive or a second cloud account. Do this once, and then review freely.
- Then review. The thirty-day trash is a safety net for the mistake you notice this month, not for the one you notice in two years.
The point of the second step is to make the review fast. It is much easier to be decisive about a hundred videos when you know the handful that genuinely matter are already safe somewhere else.
Recording smaller in the first place
If storage is a recurring problem, the camera settings are worth ten seconds. Most people never chose 4K at 60fps; it was chosen for them.
On iPhone: Settings › Camera › Record Video. On Android the equivalent lives in the camera app’s own settings, under video resolution.
1080p at 30fps is roughly a sixth the size of 4K60 and is more than most footage ever needs — it is still full HD, and it is what the video will be watched at anyway if it is watched on a phone. Leave 4K for the things you are actually filming on purpose.
Common questions
How do I find the largest videos on my phone?
Neither platform sorts a photo library by file size natively. On iPhone you can open a video and swipe up to see its size, one at a time; on Android some galleries and file managers can sort a folder by size. A cleaner app that shows the size on each card is the practical shortcut — the point is to see the number before deciding, not after.
How much space does a video take on a phone?
Roughly 400 MB a minute at 4K 60fps, 170 MB at 4K 30fps, and 65 MB at 1080p 30fps. A photo from the same camera is about 2 to 5 MB. That ratio is why a handful of videos routinely outweighs thousands of photos.
Will deleting videos free space immediately?
No. They go to Recently Deleted on iPhone or the Trash on Android and keep occupying storage — for thirty days in most cases, and currently up to sixty for backed-up items in Google Photos. Empty that bin and the space returns straight away; leave it and the space returns when the countdown ends.
Should I compress videos instead of deleting them?
Compression can recover space without losing the footage, and it is a fair option for things you want to keep but do not need at full quality. It is also lossy and irreversible, so it is worth doing deliberately rather than in bulk. Time To Swipe does not compress anything — it only helps you decide what to keep.
