What Apps Use the Most Mobile Data (And How to Reduce It)

Have you ever run out of mobile data too quickly and wondered why? You’re not alone. Some apps on your phone use a lot more data than you might expect, especially if you’re streaming videos or using social media all the time.

In this guide, we’ll walk you through the apps that consume the most data, how to check your usage, and some easy ways to save your mobile data—whether you’re at home or traveling with an eSIM.

Why You Should Care About Data Usage

Understanding how much data your apps use is important, especially if:

• You’re on a limited data plan
  
• You don’t want surprise charges
  
• You’re using an international eSIM while traveling
  
• Your mobile speed drops after hitting a data cap
  

When you know which apps are the biggest data eaters, you can make smarter choices and avoid running out of data when you need it most.

YouTube App Uses More Data Than Any Other Popular App

YouTube is a favorite worldwide, but it can be a serious data drainer.

• 480p (SD): ~700MB per hour
  
• 720p (HD): ~1.2GB per hour
  
• 1080p (Full HD): ~1.8GB per hour
  
• 4K: Up to 3-4GB per hour
  

Even a 10-minute video in HD can use over 200MB. Try lowering video quality in settings or downloading videos over Wi-Fi to watch offline.

2. TikTok’s Auto-Playing Videos Drain Data Quickly

TikTok is fun and addictive, but the non-stop video scroll burns through your data.

• Estimated usage: ~840MB per hour in HD
  

TikTok loads multiple videos in advance, even the ones you don’t watch fully. To save data:

• Set video quality to “Data Saver.”
  
• Limit usage on mobile and use Wi-Fi where possible
  

3. Instagram Eats Data with Reels and Stories

Instagram may not seem heavy, but it adds up fast with images, Reels, Stories, and autoplay videos.

• ~720MB per hour when browsing videos
  
• Uploading HD Stories and going Live uses even more
  

Switch to “Data Saver Mode” in settings to reduce consumption, especially on mobile networks.

4. Netflix Streams Burn Through Gigabytes

Netflix lets you binge on the go, but it’s one of the biggest data users.

• Low quality: ~300MB per hour
  
• Standard quality (SD): ~700MB per hour
  
• HD: ~3GB per hour
  
• Ultra HD (4K): Up to 7GB per hour
  

Save data by lowering the stream quality or pre-downloading episodes on Wi-Fi.

5. Facebook Is a Hidden Data Consumer

Facebook constantly refreshes your feed, loads high-res images, plays videos, and updates in the background.

• Estimated usage: ~260MB/hour during active use
  
• Live videos and Facebook Watch can use much more
  

Turn off auto-play for videos and use Facebook Lite if you’re trying to save data.

6. Snapchat Uses More Data Than You Might Think

Sending Snaps, watching Stories, and using AR filters all consume mobile data.

• Estimated usage: ~160MB/hour
  
• Auto-download of friend Stories and filters adds to usage
  

Disable auto-play of Stories and switch to “Travel Mode” to save data.

7. Zoom and Video Calling Apps Use Heavy Data

Zoom, Skype, FaceTime, and WhatsApp video calls are essential for work and staying in touch but use a lot of bandwidth.

• Zoom HD call: ~1GB/hour
  
• WhatsApp video call: ~300MB/hour
  
• Skype video call: ~500MB/hour
  

Use Wi-Fi for longer calls or switch to audio-only mode when possible.

8. Google Maps Uses Less Data—Unless You’re Navigating All Day

While not as data-heavy as others, using Google Maps for hours, especially with satellite view and live traffic, can build up usage.

• ~5MB per hour for simple navigation
  
• Up to 20MB+ per hour with traffic and satellite
  

Download maps for offline use before your trip to reduce data use while traveling.

9. Spotify and Music Apps Can Add Up Over Time

Music apps like Spotify, Apple Music, and YouTube Music use less data than video—but hours of streaming still add up.

• Low quality (24kbps): ~90MB per 3 hours
  
• High quality (320kbps): ~150MB/hour
  

Use offline mode to download playlists when connected to Wi-Fi.

10. Online Games Like PUBG and Call of Duty Can Use More Than You Think

Gaming apps don’t just use data during play—they often download patches, voice chat, and graphics updates.

• Estimated data usage: ~60MB–150MB/hour
  
• Updates and patches: 100MB–1GB each
  

Play on Wi-Fi when possible and turn off auto-updates on mobile data.

How do you check your data usage per app?

iPhone Users:

• Go to Settings > Mobile Data
  
• Scroll down to see data usage by app
  

Android Users:

• Go to Settings > Network & Internet > Data Usage > Mobile Data Usage
