FAQs

How much data does Netflix use per hour?

Roughly 1 GB per hour in standard definition, 3 GB per hour in HD and up to 7 GB per hour in 4K Ultra HD. Other services are similar, though exact bitrates vary.

How can I reduce my streaming data usage?

Lower the playback quality in the app settings, download shows over Wi-Fi for offline viewing, and turn off autoplay so episodes do not keep playing unattended.

Does music streaming use much data?

Far less than video — typically around 150 MB per hour at normal quality, so even heavy listeners rarely trouble a data cap with music alone.

Are these figures exact?

They are estimates based on typical bitrates. Real usage depends on the service, the specific content, and settings such as HDR or high frame rates.
