📌 1. whatsapp — Generally Light on Data

WhatsApp is primarily a messaging and calling app, so its basic activities are low on data usage:

✔ Text messages use just a few kilobytes each.
✔ Voice calls use only a few megabytes per minute.
✔ Video calls on whatsapp typically use around 5–8 MB per minute (~300–500 MB per hour) depending on quality.

👉 This means unless you’re making lots of long calls or constantly sharing media, whatsapp tends to use relatively low data compared to social feed apps.

📸 2. instagram — Much Higher Data Demand

Instagram is a media‑heavy social network where scrolling through photos, watching videos and browsing Reels/stories drives significantly higher data consumption:

📊 Estimated data usage on Instagram:

  • Browsing photos/feed: ~60–100 MB per hour
  • Watching videos or Reels: ~300–600 MB per hour
  • Continuous video content (Reels/Live): ~400–900 MB per hour
  • Uploading media (photos/videos) also adds to data usage

👉 Because of all the images and videos that auto‑load while you scroll, instagram generally uses far more mobile data than WhatsApp.

🧠 3. Why instagram Uses More Data

Here’s why instagram tends to eat more of your mobile plan:

  • 📷 Automatic media loading: Videos and high‑resolution images preload in your feed.
  • 🎥 Reels & Stories: These are video‑intensive and play automatically as you browse.
  • 🔄 Background Activity: instagram may refresh and download content in the background unless you enable data saver modes.

In comparison, WhatsApp’s core purpose is text, voice messages and calls, which are much lighter unless you share/watch a lot of videos or large files.
