GoKawiilVideo streaming remains the biggest data drain on smartphones, breakdown shows
A comparison of major apps found that video streaming services like YouTube, Netflix and Prime Video consume the most mobile data, with usage climbing sharply at higher resolutions—YouTube alone can burn through over 15GB per hour at 4K. Video calling apps such as Zoom use less per hour overall, though group calls increase consumption because separate audio and video streams are downloaded for each participant.
GoKawiil's interpretation of the reporting above, not reported fact.
As mobile data plans remain capped or tiered for many users, understanding which everyday apps quietly consume the most bandwidth can help people avoid unexpected overage charges or slowdowns. It also highlights how quality settings—often overlooked by users—can dramatically change data costs for the same content.
- YouTube at 4K can use over 15GB of data per hour, the highest among tested apps.
- Netflix is comparatively data-light, ranging from 300MB to 7GB per hour depending on quality.
- Zoom group calls consume more data than one-on-one calls due to multiple video/audio streams.
