YouTube also supports HDR video, which uses additional data. A higher FPS results in smoother video, but also more data usage as you'd expect. Note that for 720p quality and above, YouTube also supports videos at 60FPS (frames per second) instead of the standard 30FPS. YouTube Quality Data Usage ComparedĪpplying this same calculation process to YouTube's other quality options results in the following estimates for YouTube data usage per hour. Multiplying this by 60 seconds means that 480p video uses around 9.375MB of data per minute on YouTube.ĩ.375MB per minute times 60 minutes in an hour results in roughly 562.5MB of data per hour of YouTube streaming at 480p. Since there are eight bits in one byte, 1.25Mbps divided by eight equals roughly 0.156 megabytes per second of video. Other video streaming services use a lot of data, too.ġ,250Kbps (kilobits per second) divided by 1,000 gives us 1.25Mbps (megabits per second). This isn't limited to just YouTube, though. Video is made up of many thousands of pixels that can change several times per second, meaning there's a lot of information that has to pass through the internet to reach your device.Ĭompared to downloading an image or streaming audio, video is a lot more complicated, so it uses more mobile data. The simple answer is that transmitting video is an information-heavy operation. But anywhere else, watching YouTube consumes data. If you're on Wi-Fi, you can watch YouTube videos without using data. As a result, reducing mobile data usage is a concern for many.
That includes using messaging apps such as WhatsApp, streaming music on Spotify or other services, browsing social media sites and the web, and watching videos. Aside from calling and SMS texting, almost everything you do on your smartphone uses data when you're not connected to Wi-Fi. Just so we're clear before we proceed: Yes, YouTube uses mobile data.
