What is Background App Refresh in Ios
what is background app refresh in ios is a setting that lets apps update content in the background, even when you are not actively using them. It can help apps like Mail, Messages, News, and social or navigation apps show fresher information when you reopen them, but it may also use battery power and mobile data.
What Background App Refresh Does
Background App Refresh allows iPhone and iPad apps to check for new content, sync updates, and prepare information before you open them. For example, an email app may fetch new messages, a news app may load recent headlines, or a travel app may refresh trip details in the background.
It does not mean apps are constantly running at full speed. iOS manages when and how often background activity happens, based on factors like your usage patterns, power status, and network conditions.
How Background App Refresh Works
When the feature is turned on, iOS can briefly wake an app in the background so it can update itself. The app might:
- Download new content
- Sync account data
- Refresh feeds or lists
- Update cached information
- Prepare content for faster opening later
The key point is that this happens behind the scenes. You do not need to open the app first, which can make the app feel faster and more current when you return to it.
Background App Refresh vs Push Notifications
People often confuse background app refresh with push notifications, but they are different.
| Feature | What it does | Example |
|---|---|---|
| Background App Refresh | Lets apps update content in the background | A news app loads fresh headlines before you open it |
| Push Notifications | Alerts you when something happens | You receive a message or order update alert |
A notification can tell you something new happened, while background app refresh helps the app prepare updated content. An app may use one, both, or neither.
Does Background App Refresh Use Battery or Data?
Yes, it can use both, though the amount varies by app and how often it refreshes. Apps that sync frequently or move a lot of data in the background may have a bigger impact than apps that refresh rarely.
This is one reason some users turn it off for apps they do not need to update all the time. If battery life is a concern, reducing background activity can sometimes help. If mobile data is limited, background refresh may also contribute to data usage.
On the other hand, disabling it for every app is not always necessary. Some apps benefit more than others, and iOS already tries to manage background activity efficiently.
Should You Turn It On or Off?
There is no single right answer. It depends on how you use your apps.
Keep Background App Refresh on for apps you want to stay current, such as:
- Messaging apps
- Calendar or task apps
- Weather apps
- News apps
- Navigation or travel apps
Consider turning it off for apps that do not need frequent updates, such as:
- Games
- Shopping apps you use occasionally
- Static reference apps
- Apps you rarely open
If you are trying to improve battery life or reduce data use, turning it off for selected apps is usually a better approach than disabling it everywhere.
How to Turn Off Background App Refresh on iPhone
You can disable the feature for all apps or just specific ones.
Turn It Off for All Apps
- Open Settings.
- Tap General.
- Tap Background App Refresh.
- Tap Background App Refresh again at the top.
- Select Off.
Turn It Off for Specific Apps
- Open Settings.
- Tap General.
- Tap Background App Refresh.
- Use the switches next to individual apps to turn the feature on or off.
You can also choose whether background refresh is allowed over Wi-Fi only or over Wi-Fi and cellular data, depending on the options shown on your device.
When Background App Refresh Helps Most
This setting is most useful for apps where recent information matters. A few good examples are:
- Messaging and email, so recent messages appear quickly
- Navigation apps, so trip or route details stay current
- News and sports apps, so feeds and scores refresh before you open them
- Task and calendar apps, so changes sync in the background
If an app feels slow to load or always opens with outdated content, background refresh may be part of the solution.
Common Myths and Misunderstandings
Closing an app does not always save battery
Many people force close apps thinking it will stop all background activity and improve battery life. In most cases, iOS already manages apps efficiently, and repeatedly closing apps can even be less convenient than simply adjusting Background App Refresh.
Background App Refresh is not the same as app permissions
This setting does not grant access to your camera, microphone, photos, or location. Those are separate permissions controlled elsewhere in iPhone settings.
It is not always necessary for good performance
Some apps work perfectly well without background refresh. If an app only needs to update when you open it, disabling the feature will not usually hurt the experience much.
What to Do If an App Is Not Updating Properly
If an app seems stuck, stale, or delayed, Background App Refresh is only one possible factor. Try these checks:
- Make sure the app has Background App Refresh enabled
- Confirm the app is allowed to use Wi-Fi or mobile data as needed
- Check whether Low Power Mode is on, since it can limit background activity
- Open the app manually to see whether it syncs after launching
- Update the app from the App Store
- Restart the iPhone if the problem continues
If the app still does not refresh correctly, the issue may be with the app itself, your network connection, or another setting unrelated to Background App Refresh.
How It Differs from Location Services
Background App Refresh and Location Services can both operate when you are not actively using an app, but they do different jobs.
- Background App Refresh updates content and data
- Location Services lets apps use your device location when permitted
An app can use one without the other. For example, a weather app may refresh data in the background without constantly tracking your location, while a navigation app may need location access even if background refresh is off.
Best Practice for Most Users
A sensible approach is to leave Background App Refresh on for a small group of apps that genuinely benefit from it, and turn it off for everything else. That gives you a balance between convenience, battery life, and data use.
If you are unsure, start by disabling it for low-priority apps and watch whether you notice any difference in battery life or app behavior over a few days. That usually tells you more than turning it off blindly for every app.
