Does downloading videos use a lot of mobile data?
Downloading a video uses roughly what the file weighs: if the video is 200 MB, the download uses about 200 MB of your mobile data. A 5-minute clip in 1080p is around 150-300 MB; in 720p, half that; and if you only grab the audio in MP3, barely 5-10 MB. Choosing the right quality is the way to use less data.
How much data it uses by quality
| Format / quality | Data per 5 min (approx.) | When to choose it |
|---|---|---|
| 4K | 700 MB - 1.5 GB | Only on Wi-Fi; uses a huge amount. |
| 1080p (Full HD) | 150 - 300 MB | A good balance if you have data to spare. |
| 720p (HD) | 75 - 150 MB | Recommended to save data on mobile. |
| MP3 (audio only) | 5 - 10 MB | If you only want the music or the sound. |
These figures are a guide; the real size depends on the content. We go into it in how much a video weighs by quality.
How to use less data when downloading
- Download in 720p instead of 1080p or 4K: the difference on a phone screen is minimal and the saving is huge. Guide: which resolution to choose.
- If you only want the sound, grab the MP3: it uses a fraction. Use the MP3 converter.
- Download the heavy stuff (4K, long videos) on Wi-Fi and save your data for short clips.
- Downloading once and watching offline uses less than streaming the video several times. We cover it in downloading videos to watch offline.
Does downloading use more than streaming?
Downloading a video uses the same as watching it once at that quality. The advantage is that, once downloaded, you can watch it as many times as you want without using more data. So if you're going to watch something several times (a song, a tutorial), downloading it once is more worthwhile than streaming it each time.
Frequently asked questions
How much data does downloading a video use?
Roughly what the file weighs. A 5-minute 1080p video uses about 150-300 MB; in 720p, half that; and in MP3 (audio only), barely 5-10 MB. Choosing a lower quality greatly reduces usage.
How do I download a video using less data?
Choose 720p instead of 1080p or 4K, or grab only the audio in MP3 if you don't need the picture. And leave heavy downloads (4K, long videos) for when you have Wi-Fi.
Does downloading or streaming the video use more?
Downloading uses the same as watching it once at that quality. But once it's downloaded you watch it as many times as you want without using more data, so in the long run it saves if you're going to watch it several times.
Does downloading in 4K use a lot?
Yes, a huge amount: a 5-minute 4K video can use between 700 MB and 1.5 GB. It's best to download 4K only on Wi-Fi and use 720p or 1080p on mobile data.
