How to Stop Apps from Using Data in the Background?

If you are trying to work out how to stop apps from using data in the background, the good news is that the fix is usually straightforward. 

Most of the time, it comes down to switching off background data for the apps you do not need, turning on built-in data-saving features, and checking a few sneaky settings that quietly use mobile data without you noticing. 

This matters because background data is one of those things that feels unfair. You barely used your phone, but somehow your allowance has dropped again. 

A bit of Instagram, some maps, a few messages, and suddenly, you are wondering where the rest of your data went. In real life, it is often not one massive app draining everything. It is lots of little apps quietly doing things in the background all day. 

What is Background Data? 

Background data is the mobile data apps use when you are not actively using them on screen. 

That can include refreshing feeds, checking for updates, syncing files, loading messages, backing things up, or quietly updating content in the background. 

It sounds harmless, but when several apps are doing it at once, the total can add up much faster than people expect. 

A very normal example is this: you check your phone in the morning, answer a few messages, scroll for a couple of minutes, then later realise several hundred megabytes are already gone. 

It feels random, but it usually is not. It is often background activity quietly ticking away behind the scenes. 

How to Stop Apps from Using Data in the Background? 

If you want the simplest answer, do these first: 

1. Check which apps are using the most mobile data  
2. Turn off mobile data for apps you do not need away from Wi-Fi  
3. Restrict background data or background refresh  
4. Turn on your phone’s built-in data-saving mode  
5. Watch out for settings that switch to mobile data when Wi-Fi is weak  

That solves most of the problem for most people. 

The mistake a lot of people make is trying to fix everything at once. You do not need to ban every app from the internet. You just need to stop the unnecessary ones from doing too much when you are not using them. 

How to Stop Apps Using Data in Background on iPhone? 

On iPhone, the easiest place to start is Settings > Mobile Data or Settings > Cellular. 

Scroll down, and you will see a list of apps that are allowed to use mobile data. If there are apps you do not need to use data while you are out and about, switch them off. That app will still work on Wi-Fi, but it will stop eating into your mobile allowance. 

This is especially useful for things like: 

• shopping apps  
• games  
• streaming apps  
• Social media apps you do not need on the move 
• backup, or cloud-based apps  

Then check Settings > General > Background App Refresh. 

This is one of the biggest hidden causes of background data use on iPhone. You can turn it off completely or set it to work on Wi-Fi only. For most people, Wi-Fi only is the better middle ground. Your apps still refresh when you are at home or in the office, but they stop doing it on mobile data. 

There is also another setting worth checking: Wi-Fi Assist. 

This feature helps when your Wi-Fi signal is weak by quietly switching to mobile data. That sounds useful, but it can also explain why your data disappears faster than expected, especially at home, in cafés, or on patchy public Wi-Fi. If you want tighter control, switch it off. 

If you want to be even stricter, turn on Low Data Mode. That helps reduce background activity, automatic updates, and other things that quietly burn through data without adding much value day to day. 

How to Stop Background Apps Using Data on Android? 

On Android, the wording can vary a bit depending on the phone, but the general path is usually something like: 

Settings > Network & Internet / Connections > Data Usage 

From there, you can usually check which apps are using the most mobile data. 

This is worth doing because it often tells the story very quickly. Sometimes it is obvious. A streaming app has been used loads. Other times it is more surprising. A shopping app, email app, or social app you barely remember opening is quietly sitting near the top of the list. 

Once you find the apps that are doing the damage, open them individually and turn off background data if you do not need them to use mobile data all the time. 

This is especially helpful for: 

• Social media apps are constantly refreshing  
• games downloading updates  
• video apps preloading content  
• cloud apps syncing in the background  
• apps that do not need to stay live all day  

Android also has a feature called Data Saver. 

This is one of the easiest wins if you want a simple fix. Once it is on, most apps stop using mobile data in the background unless you specifically allow them. If you are not the kind of person who wants to manage every app one by one, this is often the better option. 

A very relatable example here is someone commuting every day with maps, Spotify, Instagram, Gmail, and a couple of shopping apps installed. They may only actively use one or two of them during the journey, but the others can still be refreshing, checking, or syncing in the background. That is why the data goes faster than expected. 

Which Apps Should You Restrict First? 

Not every app should be treated the same. 

Some apps are worth leaving alone because they are supposed to stay updated in the background. Messaging apps, banking apps with alerts, or navigation apps can be genuinely useful when they keep some background access. 

The ones worth restricting first are usually: 

• social media apps  
• shopping apps  
• video apps  
• games  
• apps you hardly use but forgot to delete  
• cloud storage apps doing automatic syncs  

That is usually where the unnecessary drain comes from. 

The aim is not to make your phone unusable. The aim is to stop waste. 

Other Settings that Quietly Use More Data than People Realise 

There are a few things people often miss. 

One is automatic app updates over mobile data. Another is cloud backup. Another is photo syncing. Another is apps that autoplay videos or refresh feeds the second you open them. 

A common real-world example is this: someone takes a few photos while out, then later realises the phone has quietly started backing them up over mobile data. 

Or they open Instagram for two minutes and end up using far more data than expected because videos start loading immediately. 

That is why checking your broader data settings matters, not just the apps themselves. 

If your phone still seems to chew through data after turning background data off for a few apps, look at: 

• automatic app updates  
• cloud backup settings  
• photo sync settings  
• autoplay video settings  
• high-quality streaming defaults  

Usually, there is more than one thing going on. 

Conclusion 

If you want to stop apps from using data in the background, the best approach is simple: find the apps using the most data, cut off the ones that do not need mobile access, and switch on the phone’s built-in data-saving features. 

That is usually enough to make a noticeable difference. 

The main thing to remember is that background data is rarely one dramatic problem. It is usually lots of small things adding up. A feed refreshing here, a backup there, an app update in the background, a weak Wi-Fi connection quietly switching to mobile data. Once you start tightening those up, the difference is often immediate. 

And if your data still runs out fast after all of that, then the issue may not be background waste anymore. It may simply be that your plan no longer matches how you actually use your phone.
