How to free up space on the OnePlus 9 Pro
Short answer
To free up space on the 9 Pro, open Settings > Storage & memory to see what is using it, clear duplicates with Google Photos: Free up space on this device, then empty Photos's Recently Deleted. A default 12 MP photo is about 3.6 MB, so 5,000 photos take roughly 18 GB of the 128 GB base model.

Where is the storage screen on the 9 Pro?
The 9 Pro launched in March 2021 with Android 11 and OxygenOS 11. On that software the storage screen is Settings > Storage & memory.
Other OxygenOS versions use a different path; the OnePlus guide lists them.
How much space do 9 Pro photos take?
9 Pro: 48 MP main sensor, 12 MP by default, plus 50 MP ultrawide, 8 MP 3.3x telephoto, 2 MP mono. 1,000 default 9 Pro shots take about 3.6 GB.
| File | Typical size | Fits in 10 GB |
|---|---|---|
| Default photo (12 MP) | about 3.6 MB | about 2,778 |
| Full-resolution mode (48 MP) | about 11.5 MB | about 870 |
| RAW / DNG (12 MP) | about 23 MB | about 435 |
| One minute of video at 8K 30fps | about 600 MB | about 17 minutes |
Switching the 9 Pro to its 48 MP mode makes each shot about 11.5 MB, roughly 3 times a default photo, so 200 of them use 2.3 GB. RAW files from the 9 Pro run to about 23 MB each, which is why RAW folders fill a phone faster than anything except video. Recording at 8K 30fps, the 9 Pro writes about 600 MB a minute, so a ten-minute clip takes 6.0 GB, the same as 1,667 default photos. Selfies from the 16 MP front camera are about 4.8 MB each.
What is specific to the 9 Pro?
Adds 4K 120fps video on top of 8K 30fps; both make very large files. Outputs JPEG and DNG.
Which built-in cleaners did the 9 Pro ship with?
Out of the box on OxygenOS 11, the 9 Pro has Google Photos: Free up space on this device (Google Photos > profile picture > Free up space on this device) and Files by Google cleaning suggestions (Files by Google > Clean). How each works is in the OnePlus guide.
Where do deleted photos go on the 9 Pro?
On the 9 Pro, Photos's Recently Deleted holds them for 30 days (Photos > Albums > Recently Deleted). It launched on Android 11, so it also has Android's system trash.
How much of each 9 Pro storage option does a big gallery use?
| Storage option | 5,000 default photos | 30 minutes of top-quality video |
|---|---|---|
| 128 GB | 18 GB (14%) | 18 GB (14%) |
| 256 GB | 18 GB (7%) | 18 GB (7%) |
On the 128 GB 9 Pro, every 10 GB you free holds about 2,778 more default photos, and a gallery of 20,000 photos would fill 56% of it. On the 256 GB 9 Pro, every 10 GB you free holds about 2,778 more default photos, and a gallery of 20,000 photos would fill 28% of it.
