How It Works

How Data Usage Is Estimated

Different activities consume data at different rates per hour.

Approximate Data Usage Per Hour

  • Video streaming (720p): ~1.5 GB/hr
  • Music streaming: ~0.07 GB/hr (70 MB)
  • Social media: ~0.3 GB/hr (300 MB)
  • Web browsing: ~0.06 GB/hr (60 MB)

    • Worked Example

    10 hrs video, 20 hrs music, 30 hrs social, 15 hrs browsing per month.

    streaming_hours = 10music_hours = 20social_hours = 30browsing_hours = 15
    1. 01Video = 10 x 1.5 = 15.0 GB
    2. 02Music = 20 x 0.07 = 1.4 GB
    3. 03Social = 30 x 0.3 = 9.0 GB
    4. 04Browsing = 15 x 0.06 = 0.9 GB
    5. 05Total = 15.0 + 1.4 + 9.0 + 0.9 = 26.3 GB

    Frequently Asked Questions

    How much data does the average person use?

    The average US smartphone user consumes about 12-17 GB per month. Heavy users with lots of video streaming can easily exceed 30 GB.

    Does streaming quality affect data usage?

    Dramatically. SD video uses ~0.7 GB/hr, HD ~1.5 GB/hr, and 4K ~7 GB/hr. Lowering quality in streaming app settings saves significant data.

    What uses the most data?

    Video streaming is by far the largest data consumer. One hour of HD video uses more data than 20 hours of music streaming.
