How much space do Zenfone 9 photos take?
Zenfone 9: 50 MP main sensor, 12.5 MP by default, plus 12 MP ultrawide. 1,000 default Zenfone 9 shots take about 3.8 GB.
| File | Typical size | Fits in 10 GB |
|---|---|---|
| Default photo (12.5 MP) | about 3.8 MB | about 2,632 |
| Full-resolution mode (50 MP) | about 12 MB | about 833 |
| RAW / DNG (12.5 MP) | about 24 MB | about 417 |
| One minute of video at 8K 24fps | about 600 MB | about 17 minutes |
Switching the Zenfone 9 to its 50 MP mode makes each shot about 12 MB, roughly 3 times a default photo, so 200 of them use 2.4 GB. RAW files from the Zenfone 9 run to about 24 MB each, which is why RAW folders fill a phone faster than anything except video. Recording at 8K 24fps, the Zenfone 9 writes about 600 MB a minute, so a ten-minute clip takes 6.0 GB, the same as 1,579 default photos. Selfies from the 12 MP front camera are about 3.6 MB each.
What is specific to the Zenfone 9?
