Data is expensive, and it often disappears faster than you expect. The good news is that small changes on your phone can make each gigabyte last much longer. This guide shows you how to save data on Android with simple settings you can change today, whether you use MTN, Airtel, Glo or 9mobile.
Most data is not used by the apps you open. Instead, it is quietly used in the background by updates, backups and autoplay videos. So the first step is to find what is eating your data.
Step 1: Check which apps use the most data
Android shows exactly where your data goes:
- Open Settings.
- Tap Network & internet or Connections, then Data usage.
- Tap Mobile data usage to see a list of apps.
The menu names differ slightly between Samsung, Tecno, Infinix, Xiaomi and other brands. Still, you will usually find it by searching “data usage” in Settings. The top apps on that list are your biggest data spenders.
Step 2: Turn on Data Saver
Data Saver is the single most useful way to save data on Android. It stops most apps from using data in the background.
- Go to Settings and search for Data saver.
- Turn it on.
- Allow only important apps, such as WhatsApp, to keep using background data.
Step 3: Stop automatic app updates on mobile data
App updates can use hundreds of megabytes at a time. Make them wait for Wi-Fi:
- Open the Google Play Store.
- Tap your profile picture, then Settings.
- Open Network preferences.
- Set Auto-update apps to Over Wi-Fi only.
Step 4: Save data on WhatsApp
WhatsApp is often the top data user in Nigeria because of photos, videos and voice notes.
- Open Settings > Storage and data.
- Under Media auto-download, set photos, audio, videos and documents to download only on Wi-Fi, or never.
- Turn on Use less data for calls if the option appears.
- Avoid backing up chats to Google Drive over mobile data.
Step 5: Control video and social media apps
Videos use far more data than text or photos. A few settings help a lot:
- YouTube: lower the default video quality and turn off autoplay.
- TikTok, Instagram and Facebook: look for a data saver option in each app’s settings.
- Stop autoplay videos wherever the option exists.
- Download videos on Wi-Fi to watch later offline, where the app allows it.
Step 6: Use lighter apps and browsers
- Use “lite” or “Go” versions of apps where available.
- Choose a browser with a data-saving mode.
- Close apps you are not using so they do not refresh in the background.
Step 7: Stop Android backups and sync on mobile data
Photo backup apps can upload hundreds of photos at once. Set Google Photos and other backup tools to back up only on Wi-Fi. Also review which accounts sync automatically in Settings > Accounts.
Step 8: Set a data limit and warning
Android can warn you before you use too much:
- Open Data usage in Settings.
- Tap Data warning and limit or Billing cycle.
- Set a warning, for example at 80% of your bundle.
Then check your remaining data often. Our guide on how to check data balance lists the codes for every network.
Buy smarter bundles too
Saving data works best with the right plan. Compare offers in our MTN cheap data code guide, our Airtel data plans and our Glo data plans. Also turn off mobile data when your bundle ends, so your phone does not start browsing with airtime.
