Monitor & Manage Data Usage on Android
Network & internet settings show a breakdown of mobile data and Wi-Fi usage per app, and let you set a data warning or hard limit to avoid unexpectedly exceeding your plan. Individual apps can also be restricted from using background data to further control consumption.
How to open Data Usage / Network & Internet
- Open Settings → Network & internet → SIMs (or Data usage).
- Review the usage graph and set your billing cycle date.
- Tap 'Data warning & limit' to set a threshold and optional automatic cutoff.
- Tap an individual app to restrict its background data if needed.
What you should know
- Data usage can be reviewed for a custom billing cycle date range, not just the calendar month.
- A data warning sends a notification at a chosen threshold, while a data limit can automatically disable mobile data once reached.
- Background data can be turned off per app, stopping updates and syncing while that app isn't actively open.
- Wi-Fi networks can be marked as metered, applying the same data-saving restrictions used for mobile data.
The data usage shown on your device is an estimate and may differ slightly from your carrier's official billing measurement — check with your carrier for exact figures near a plan's limit.
Why it matters
Unexpected overage charges or a mid-month data cutoff are frustrating and entirely avoidable once you know where your data is actually going. The per-app breakdown turns a vague sense of 'my data disappears fast' into an actionable fix, like restricting one background-heavy app instead of blaming the whole plan. Setting a data warning and limit also builds in a safety net, so a busy month or an app misbehaving in the background doesn't quietly blow past your plan before you notice.
Best practices
- Set both a data warning and a hard data limit slightly below your actual plan cap, giving yourself a buffer before overage charges apply.
- Check the per-app breakdown monthly to catch a newly installed app quietly consuming more data than expected.
- Restrict background data for apps you only use occasionally, rather than leaving every app free to sync at all times.
- Mark unfamiliar or metered Wi-Fi networks (like a mobile hotspot) as metered so background restrictions apply there too.
- Adjust your tracked billing cycle date to match your actual carrier billing date for an accurate month-to-date view.
Common problems and fixes
- Reported data usage on the phone doesn't match the carrier's bill.
- Treat the on-device figure as an estimate, and check with your carrier directly if you're close to a plan limit rather than relying solely on the phone's count.
- One app is responsible for a large, unexplained share of data usage.
- Tap into that app's entry under Data usage, restrict its background data, and check whether an in-app setting (like auto-play video) is driving the usage.
- Data limit cuts off mobile data earlier in the month than expected.
- Review the configured limit and billing cycle start date under Data warning & limit, since a misconfigured cycle date can trigger the cutoff prematurely.
- Apps stop syncing in the background after marking a Wi-Fi network as metered.
- This is expected, since metered Wi-Fi applies the same background data restrictions as mobile data; unmark the network if that behavior isn't wanted.
Tips and tricks
- Set your tracked billing cycle date to match your carrier's actual billing date for a month-to-date view that lines up with your bill.
- Check the data usage screen right after a trip or heavy streaming weekend to catch any surprises before the billing cycle closes.
Frequently asked questions
What's the difference between a data warning and a data limit?
A data warning only sends a notification at a chosen threshold, while a data limit can automatically turn off mobile data once that threshold is reached.
Does restricting background data break notifications for that app?
It can delay them, since the app can't refresh data until actively opened, so restrict background data selectively rather than for apps needing real-time alerts.
Can I track Wi-Fi data usage the same way as mobile data?
Yes, Android tracks Wi-Fi usage separately per app, and you can mark specific Wi-Fi networks as metered to apply the same controls used for mobile data.

- NFC & Tap to PayNFC (Near Field Communication) is the short-range radio that lets your phone exchange data with a nearby reader, most commonly used for contactless payments through Google Wallet at supported terminals. It's also used for pairing some accessories and reading NFC tags, but payments are its most common everyday use.
- VPNVPN settings let you add, connect to, and manage virtual private networks that route your device's traffic through an encrypted tunnel, commonly used for work access or added privacy on untrusted networks. Android also supports an 'always-on VPN' mode that blocks other network traffic until the VPN connects.
- Nearby ShareNearby Share — recently rebranded Quick Share — lets you send photos, videos, links, and files directly to another nearby Android device, Chromebook, or Windows PC using a mix of Bluetooth and Wi-Fi, without needing cellular data or a shared internet connection. Visibility settings control exactly who can discover your device and send you something.
- Airplane ModeAirplane Mode simultaneously disables cellular, Wi-Fi, and Bluetooth radios with a single toggle, complying with airline requirements while optionally letting you re-enable Wi-Fi or Bluetooth individually afterward.
