Stop Apps From Eating Your Mobile Data in the Background
Your mobile data plan can run out long before the month ends, and the cause is often apps quietly using data when you are not looking at them. This guide shows you how to find those apps and stop them, one app at a time.
Follow these steps
- Find your biggest data users first. On iPhone, go to Settings, then Mobile Data, and scroll down: each app shows how much mobile data it has used. On Android, go to Settings, then Network and internet, then Data usage or Mobile data usage, and look at the per-app list. Start with the apps at the top of the list, not with every app on your phone.
- Turn off mobile data for apps that do not need it. On iPhone, switch off Mobile Data next to any app that only needs to work on Wi-Fi, such as a video or cloud app. On Android, open the app in the data usage list and turn off Background data. The app will still work normally when you are on Wi-Fi.
- Stop video from playing on its own. Autoplay is one of the biggest hidden data users. In your social and video apps, look in their settings for Autoplay or Video playback and set it to Wi-Fi only or Off. Do this in each app you scroll through often, since the setting is per app, not phone-wide.
- Turn off background refresh for heavy apps. On iPhone, go to Settings, then General, then Background App Refresh, and switch off the apps you do not need updated in the background. On Android, the Background data switch in the previous step does the same job. Leave it on for apps where fresh information matters to you, such as a banking or messaging app.
- Set a data warning so you catch it early. On Android, you can set a data warning and limit under Data usage settings, so the phone warns you before your plan runs out. On iPhone, there is no built-in warning, so note the date your plan renews and check the Mobile Data screen once a week until the habit sticks.
- Check again after a week. Go back to the same data usage screen after a few days of normal use. If the same apps are still at the top, tighten their settings further. If your usage has dropped, you have found the right balance and can leave the settings alone.
What NOT to do
- Do not turn off mobile data for everything at once. You may block messages, security updates, or maps when you actually need them.
- Do not install a third-party app that promises to save data. It cannot see more than your phone's own settings already show, and it may collect your data instead.
- Do not confuse background data with storage. Deleting photos or files will not reduce your data use.
- Do not disable your messaging or backup apps to save data unless you understand the trade-off: messages may arrive late and backups may stop.
If your data use is still high after these steps, the remaining usage is probably video you watch on purpose, which is normal. Watch long videos on Wi-Fi where you can, and check the data screen once a month to stay ahead of surprises.
