How much data do Spotify, YouTube, Netflix and TikTok use?
Approximate usage per hour: Spotify 40–150 MB depending on quality; YouTube 260 MB at 480p up to 1.5–2 GB at 1080p; Netflix 250 MB on data saver to ~1 GB on high; TikTok 300–800 MB; Instagram reels 200–700 MB. High-quality video is always the big spender.
Per-app usage table (per hour, approximate)
| App | Quality | Usage/hour |
|---|---|---|
| Spotify | Normal (96 kbps) | ~43 MB |
| High (160 kbps) | ~72 MB | |
| Very high (320 kbps) | ~144 MB | |
| YouTube | 480p | ~260 MB |
| 720p | ~0.9 GB | |
| 1080p | ~1.5–2 GB | |
| Netflix | Data saver | ~250 MB |
| High (mobile) | ~1 GB | |
| TikTok | Auto | ~300–800 MB |
| Instagram (reels/stories) | Auto | ~200–700 MB |
| WhatsApp video call | — | ~300 MB |
| Google Maps | Navigation | ~5 MB |
Approximate values — auto-quality algorithms, ads and preloading shift the real numbers.
Three practical takeaways
- Quality matters more than the app. YouTube at 480p uses 6× less than 1080p. On a 6-inch screen the visual difference is tiny; the difference to your plan is enormous.
- Music is cheap; video isn't. Three hours of Spotify daily all month (~4 GB at normal) costs what one afternoon of high-quality Netflix does.
- Preloading is sneaky: TikTok and Instagram download videos you may never watch — they spend even while you just scroll.
