Quick Answer
To check data usage per app on Android: open Settings → Network & internet → SIMs → tap your active SIM → App data usage. You will see every app’s mobile-data consumption for the current billing period, with a split of foreground vs background usage. Tap any app to see details and turn off its background data.
Why Check Per-App Data Usage?
On a prepaid plan, a few gigabytes disappearing with no explanation is frustrating. The culprits are almost always the same:
- Auto-playing videos in social apps (foreground usage while scrolling).
- Background sync — apps uploading photos, downloading updates, or refreshing feeds while you are not using them.
- Cloud backups and app updates running on mobile data instead of Wi-Fi.
Finding the exact app takes 30 seconds once you know where the screen is. The menu path varies slightly between phone brands, so this guide covers stock Android, Samsung, and Xiaomi.
Stock Android / Pixel: How to Check Data Usage Per App on Android
- Open Settings → Network & internet.
- Tap SIMs → tap your active SIM.
- Tap App data usage.
You will see a graph of the current usage period and a list of apps sorted by data consumed. Tap any app for:
- Foreground vs background breakdown — tells you whether the app eats data while you use it or behind your back.
- A Background data toggle — turn it off to stop that app using mobile data when it is not open.
Newer builds: on some phones the path is Settings → Network & internet → Internet → tap the settings gear next to your carrier → App data usage. Same screen, slightly different route.
If your phone’s menus look different, Google’s Android Help documents the data usage settings for Pixel phones.
Samsung (One UI): How to Check Data Usage Per App on Android
Samsung renames the menus:
- Open Settings → Connections.
- Tap Data usage → Mobile data usage.
You get the same per-app list with the billing-cycle graph. Tap an app for details and background-data controls.
Xiaomi / HyperOS: Data Usage Path
- Open Settings → Connection & sharing (on older MIUI: SIM cards & mobile networks).
- Tap Data usage.
Xiaomi additionally offers per-app network permissions — you can block an app from using mobile data, Wi-Fi, or both, directly from the same area.
Wi-Fi Usage Per App
Mobile data is not the whole story — to see Wi-Fi consumption per app:
- Stock Android: Settings → Network & internet → Internet → Non-carrier data usage.
- Samsung: Settings → Connections → Data usage → Wi-Fi data usage.
Set a Billing Cycle, Warning, and Limit
Raw numbers are only half the battle — set guardrails so you get warned before the pack runs out:
- On the data-usage screen, set your billing cycle (the date your plan renews) so the graph matches your actual pack.
- Set a data warning (e.g. 80% of your pack) — Android notifies you when you cross it.
- Optionally set a mobile data limit — Android cuts mobile data entirely when the limit is hit. Use this only if overuse costs you real money; otherwise the warning is enough.
Restrict Background Data Per App
Found the culprit? Two levels of control:
Per app: Settings → Apps → [app name] → Mobile data & Wi-Fi → turn off Background data. The app only uses data when you open it.
Whole phone: Settings → Network & internet → Data Saver → turn it On. This restricts background data for all apps at once; you can whitelist apps that must stay unrestricted (like messaging).
Caution: restricting background data on messaging or banking apps can delay notifications. Only restrict apps where you are sure it is safe — social media, streaming, shopping apps.
Data-Saving Habits That Actually Work
- Play Store updates on Wi-Fi only — app updates are silent data hogs. Our guide on managing automatic app updates shows the exact setting.
- WhatsApp media — stop auto-downloads eating your pack with our WhatsApp auto-download guide — WhatsApp is often near the top.
- Streaming quality — drop video quality to 480p on mobile data in YouTube/Netflix settings; it cuts usage by more than half with barely visible difference on a phone screen.
- Offline maps and music — download on Wi-Fi once instead of streaming repeatedly.
Also worth a look: our guide to checking app permissions in the Play Store Data Safety section explains what data WhatsApp declares it collects.
Frequently Asked Questions
How do I see which app is using the most data?
Settings → Network & internet → SIMs → your SIM → App data usage. Apps are sorted with the heaviest users at the top.
What is the difference between foreground and background data?
Foreground data is used while the app is open on your screen; background data is used when the app is closed (syncing, notifications, preloading). High background usage is the usual surprise — restrict it per app.
Will restricting background data break notifications?
It can delay them for the restricted app. Keep background data on for messaging, email, and banking apps; restrict social, shopping, and streaming apps freely.
How do I set a data limit on Android?
On the data-usage screen, set your billing cycle date first, then enable “Set data warning” and “Set data limit” with your amounts. Android warns at the warning level and cuts mobile data at the limit.
Does Data Saver slow down my phone?
No — it only restricts background network access. Your apps run normally; they just cannot silently use data when closed. You can exempt individual apps.
Why does my data finish so fast even though I barely use my phone?
Almost always background usage: cloud photo backup, app auto-updates on mobile data, or a social app preloading videos. Check the per-app list — the top 2–3 apps usually explain 80% of it.
Final Words
Checking data usage per app on Android is the fastest way to stop mystery data drain: open the App data usage screen, find the top offenders, and restrict background data for the ones you do not need live. Pair it with a billing-cycle warning and Wi-Fi-only updates, and your pack will start lasting the full month.
