Background App Refresh is one of those iPhone settings that attracts bad advice because the name sounds more dramatic than the behavior. It is easy to imagine apps constantly running behind your back, draining the battery and burning through cellular data. In practice, iOS is much stricter than that. Background App Refresh gives apps limited opportunities to update content before you open them, and iOS decides when those opportunities make sense.
That does not mean the setting is irrelevant. It means the right question is not "Should I turn it all off?" The better question is "Which apps benefit from being ready before I open them?" A weather app, map app, cloud storage app, or work tool may be worth leaving on. A shopping app you open twice a month probably is not.
This guide explains what Background App Refresh does, what it does not control, when turning it off helps, and how to tune it without making your iPhone feel slower or less reliable.

What Background App Refresh Actually Does
Background App Refresh lets supported apps update content while you are not actively using them. The most visible benefit is freshness. When you open an app, the latest feed, route, file list, podcast episode, or dashboard may already be closer to ready.
It is not the same as keeping an app fully alive all the time. iOS still manages background execution aggressively. Battery level, Low Power Mode, network conditions, recent usage, app behavior, and system priorities all affect what happens.
Think of Background App Refresh as permission for small, opportunistic updates. It is not a guarantee that every app will refresh instantly, and it is not a license for every app to run continuously.
Where to Find the Setting
On most current iPhones, the path is:
- Open Settings
- Tap General
- Tap Background App Refresh
- Tap Background App Refresh again for the global mode
The global choices are usually:
| Option | What it means |
|---|---|
| Off | Apps cannot use Background App Refresh |
| Wi-Fi | Apps may refresh in the background when connected to Wi-Fi |
| Wi-Fi & Cellular Data | Apps may refresh over Wi-Fi or mobile data |
Below that, you will see individual app switches. That app list is where the useful tuning happens. The global switch is blunt. The per-app switches let you keep convenience where it matters and remove it where it does not.
If you are tuning several built-in iPhone features at once, pair this with useful iPhone features worth setting up first. Background behavior is easier to manage when Control Center, Focus, Low Power Mode, and app permissions are not all fighting each other.
What Changes When You Turn It Off
When Background App Refresh is off for an app, the app may wait until you open it before fetching new content. That can change the experience in small but noticeable ways.
You may see:
- A feed reload after the app opens
- A cloud folder take longer to show recent files
- A podcast or news app refresh only after launch
- A task or calendar app need a moment to sync
- A travel, delivery, or map app feel less ready when opened
What does not automatically stop:
- Push notifications
- Phone calls and normal messages
- iOS updates
- App Store app updates
- Location permission itself
- Audio playback that is already allowed to continue in the background
This distinction is important. If your real problem is too many alerts, go to notification settings. If your problem is location use, review Location Services. If your problem is cellular data, check mobile data usage. Background App Refresh overlaps with those areas, but it does not replace them.
Apps You Can Usually Turn Off First
Start with apps that do not need to be ready before you open them.
Good candidates include:
- Shopping apps you rarely use
- Loyalty cards and coupon apps
- One-off travel or event apps
- Casual games
- Photo editing or scanning tools used occasionally
- News or magazine apps you do not need preloaded
- Apps you keep installed only for a specific store, venue, or service
The rule is simple: if the app is only useful after you intentionally open it, background freshness is probably optional.
Do not confuse "important app" with "important background app." A banking app may be important, but you may still prefer it to refresh only when opened. A delivery app may be unimportant most days, but very useful to keep fresh while an order is active.
Apps Worth Keeping On
Leave Background App Refresh on for apps where delay or stale information would bother you.
Stronger candidates include:
- Maps and transit apps
- Calendar and task apps
- Work chat or collaboration tools
- Cloud storage and note apps
- Podcast and audio apps that prepare content
- Travel apps during an active trip
- Health, home, or device companion apps that depend on timely updates
Cloud storage deserves special attention. If you use multiple devices, you do not want to discover at the airport, in a meeting, or at school that the file list only refreshes after you open the app. The battery saving from disabling a daily work tool may be less valuable than the friction it creates.
Location-sensitive apps are a separate category. Background App Refresh is not the same as location permission, so review both settings. For a deeper permission check, see iPhone location settings explained.
Battery Life: Do Not Blame One Setting Too Quickly
Turning off Background App Refresh can help in some cases, but it is rarely the only meaningful battery lever. Screen brightness, weak cellular signal, video streaming, navigation, camera use, background uploads, and battery health can matter more.
Apple's Low Power Mode documentation says Low Power Mode reduces background activity and turns off Background App Refresh while it is active. That is a useful clue: when you need immediate battery relief, Low Power Mode is the designed system-level tool. Manual Background App Refresh tuning is better for long-term cleanup.
A practical battery workflow looks like this:
- Turn off Background App Refresh for apps you rarely use
- Use the phone normally for several days
- Check Settings > Battery for apps with unusually high usage
- Review location and notification permissions for those apps
- Use Low Power Mode when you need short-term battery extension
Do not change ten settings at once. If the phone becomes less useful, you will not know which change caused it.
Cellular Data: Use Wi-Fi Mode Before Going Nuclear
If your concern is data usage, the global Wi-Fi option is often smarter than turning Background App Refresh off completely. It allows background refresh at home, work, or school while limiting mobile data use on the road.
This is especially useful for:
- Podcast and audio apps
- Cloud storage apps
- News apps
- Photo-related apps
- Travel apps with rich content
Still, do not assume this setting controls all data. An app can use data when you open it, upload files, stream video, or sync content in other permitted ways. To diagnose cellular usage, check Settings > Cellular and look at the app-by-app totals.
If an App Feels Broken After You Turn It Off
If an app starts feeling stale, slow, or unreliable after you change the setting, restore that app first rather than undoing everything.
Try this order:
- Turn Background App Refresh back on for the affected app
- Connect to Wi-Fi
- Open the app and let it finish syncing
- Check notification, cellular data, and location settings
- Restart the iPhone if the app still behaves strangely
- Update the app from the App Store
Low Power Mode can also confuse troubleshooting because it reduces background activity while active. If you are testing a sync problem, turn Low Power Mode off temporarily and try again.
Summary
Background App Refresh is not a hidden battery villain and not a setting you should ignore. It is a limited iOS permission that helps selected apps stay fresher before you open them.
The best setup is selective. Turn it off for rarely used shopping, game, event, and utility apps. Keep it on for maps, cloud storage, work tools, calendar apps, travel apps during a trip, and anything where stale data would waste your time. If you care about cellular data, try Wi-Fi mode first. If you need battery relief right now, use Low Power Mode.
