You can lower the amount of bandwidth video calling apps use by switching off HD video, avoiding the screen-sharing feature unless needed, and closing out other apps while you’re on those apps. Skype on the other hand uses between 2.2 GB to 7.6 GB for group video calling depending on the number of participants on the call. Participating in group video calls on Zoom for example uses anywhere from 810 MB to 2.47 GB per hour. Screen sharing and group video calling increases the data consumption and bandwidth requirements of your internet connection. The consumption will increase to up to 450MB per hour for high quality and 1.35GB per hour for HD streams.

In the case of HD group video calling with 540p videos on a 1080p screen, Teams will consume about 450MB of data per hour, and can go up to 1.3 GB for full HD calling (1080p).Īs for Skype, in one-on-one video calls, Skype uses only about 270MB of data per hour on standard quality. Meanwhile according to Microsoft, Teams is quite conservative on bandwidth utilization as It roughly uses about 225MB of data per hour for video calling. Depending on the quality of your video call stream, you'll generally consume between 540 MB (for default SD) and 1.62 GB (for 1080p, full HD) of data per hour if you're using Zoom to meet one-on-one with another user.
