Many apps continue to use data in the background even when you’re not actively using them. That’s where Android’s Data Saver feature comes in.

Data Saver on Android helps you stay in control by limiting background data usage. It’s especially helpful when you’re on a limited data plan, roaming internationally, or simply trying to avoid overage charges. 

This article will show you how to use Android’s Data Saver feature, explain how it works, and walk you through additional tips to help reduce mobile data usage and avoid surprise charges.

What Is Data Saver on Android?

Data Saver is a built-in Android setting designed to reduce how much mobile data your phone uses, especially when apps run in the background.

What it controls:

  • Limits background data: Apps can’t send or receive data unless you open them.
  • Keeps essential services running: Your phone can still make calls, send texts, and perform necessary updates.
  • Foreground apps still work: Apps you’re actively using (like YouTube or Gmail) can access data normally—unless further restricted.
  • You’re in control: You can whitelist important apps so they’re not affected by Data Saver (e.g., navigation or messaging apps).

This feature is built into Android and available on nearly all modern devices. It works silently in the background to prevent unnecessary data use without interrupting your regular phone activity.

How Does Data Saver Work?

When you enable Data Saver, Android takes several steps to limit background data use and reduce unnecessary consumption. 

It blocks most background activity, preventing apps from sending or receiving data unless they’re actively open. 

Sync frequency for apps like Gmail, Facebook, or news feeds is reduced, so you won’t get real-time updates until you open them. 

It also disables or delays data-heavy features like auto-playing videos and media downloads—which is important considering that, according to Ericsson’s 2024 Mobility Report, video accounts for over 70% of all mobile data traffic globally. 

By restricting autoplay and similar features, Data Saver helps minimize one of the biggest sources of data drain.

Tip: Device brands may customize this feature

Some Android manufacturers adjust the name or settings of Data Saver on their devices:

  • Samsung: On Galaxy devices, you’ll find it at Settings → Connections → Data usage → Data saver. This screen also includes a “Data warning & limit” option, letting you set usage alerts or caps. The images above illustrate where to find the toggle and how to whitelist individual apps.
  • Google Pixel: Pixel phones list Data Saver under Settings → Network & Internet → Data Saver. This interface clearly shows a toggle switch and an “Unrestricted data” list for exempting preferred apps.
  • Xiaomi (MIUI): Xiaomi devices handle data restrictions through battery settings. You can go to Settings → Battery & performance → Manage apps battery usage and toggle off background restrictions. The process may also appear as “Restrict background data” within individual app settings.
  • Realme: Realme UI typically places Data Saver options under Settings → Mobile Network → Data usage → Data Saving, with individual app controls available under Network permissions or Restrict Data Usage menus.
  • Huawei: Huawei labels it “Smart Data Saver”, found at Settings → Data usage → Smart Data Saver. From there, you can enable the feature and specify which apps are always allowed full data access.

Note: If your phone doesn’t clearly show a “Data Saver” option as described, use the search bar in Settings and try terms like data saver, background data, or data usage. Due to variations in Android skins, the location and label may differ slightly—but the functionality remains the same.

How to Turn On Data Saver on Android

Enabling Data Saver is quick and straightforward. Just follow these steps:

Step 1: Open the Settings app on your Android device

Step 2: Tap Network & Internet (or Connections if you’re using a Samsung phone)

Step 3: Select Data Saver (or Data Usage first if you’re using Samsung)

Step 4: Toggle the switch On

Once enabled, you should see a small icon (a plus sign in a circle) appear in your status bar. That’s your confirmation that Data Saver is active.

How to Allow Unrestricted Data for Specific Apps

Some apps need to run in the background to function properly—like WhatsApp for receiving messages or Google Maps for live traffic updates. 

If you trust certain apps and want them to work normally even when Data Saver is on, follow these steps:

Step 1: After turning on Data Saver, tap Unrestricted data access (or look for Allowed apps while Data Saver on)

Step 2: You’ll see a list of all installed apps. Toggle On for any app you want to bypass Data Saver (e.g., messaging, navigation, or ride-share apps)

Step 3: Exit the menu — your selections are saved automatically

This gives you the flexibility to save data where it doesn’t matter and allow full access where it does.

Other Tips to Save Mobile Data on Android

Data Saver is a great start, but here are more practical ways to reduce your data usage:

  • Limit Play Store auto-updates: Go to Play Store > Settings > Network Preferences > Auto-update apps and set it to Over Wi-Fi only
  • Disable auto-play in social apps: In apps like Instagram, Facebook, or X, turn off auto-playing videos under their Settings > Data usage section
  • Download content for offline use: Preload maps in Google Maps, or download music and podcasts in advance using apps like Spotify or YouTube Music
  • Manually restrict background data for specific apps: Go to Settings > Apps > [Choose App] > Mobile data & Wi-Fi and disable Background data

These extra steps give you deeper control over how your phone uses mobile data and help you avoid surprises on your bill.

Final Advice for Managing Mobile Data on Android

Data Saver is one of the easiest tools to manage your phone’s mobile usage, but staying data-conscious requires a bit of regular maintenance.

  • Check data usage often: Go to Settings > Network & Internet > Data usage to see which apps are using the most data
  • Try data-saving browsers: Use browsers like Google Chrome (Lite mode) or Opera Mini, which compress web pages before loading
  • Know your plan: Be aware of your mobile plan’s data cap and whether your carrier slows speeds (throttles) after a certain threshold
  • Enable Data Saver when traveling: Especially when roaming or using a local eSIM or prepaid SIM abroad, this feature can help you avoid expensive overages
