How much data does Zoom / Meet use?
About 540MB an hour at 1:1 video.
The reason "work trip" and "holiday" need completely different plans. An hour of group HD outweighs a whole day of everything else.
Put that on a real trip: 60 minutes a day for 10 days at 1:1 video works out at about 5.3GB , before anything else on your phone, and before the 120MB a day that background sync quietly takes.
Zoom / Meet data usage by quality
| Quality | Data | 1GB lasts | Source |
|---|---|---|---|
| Audio only | 35MB/hr | 1 days | measured |
| 1:1 video | 540MB/hr | 1.9 hours | measured |
| Group HD | 2.0GB/hr | 31 minutes | measured |
Published means the service states the figure itself. Bitrate means it's arithmetic from a documented stream rate. Measured means it's corroborated across independent tests. Real usage moves with signal strength and how aggressively the app pre-buffers.
