How to turn off background app refresh and extend iPhone battery
Background App Refresh is one of those iPhone settings that looks small until you notice what it permits: apps can update their content and data while you are using another app or have left your phone on the table. Social feeds refresh, weather maps download, email attachments arrive and shopping apps check for new offers. None of this needs to be visible, yet every update can wake the processor, connect to a mobile network and use some energy. Turning the feature off is a practical way to reduce that background work.
The payoff depends on your apps and your day. Someone who spends hours on a crowded train in Sydney may value uninterrupted messages, while a spare phone sitting beside a router in a Melbourne home may benefit little from half a dozen apps refreshing overnight. On recent iPhones, efficiency is already high, so background activity does not automatically create a dramatic battery gain. It can still matter when many apps run, reception is poor or the phone is working hard in the heat.
This guide explains how to change the setting, what notifications and updates you may lose, and how to judge the difference on your own device. It also covers the Australian details that can change the result: hot summers, patchy mobile coverage, city commutes and the battery claims you should expect sellers to respect under Australian consumer law. The aim is a controlled test, not a rule that every iPhone owner must apply.
Start with the habits you already have rather than installing extra optimisation tools. Use your iPhone as usual, note where the battery goes, and change one group of apps at a time. That approach makes it easier to keep the setting if it works and restore it if a particular service becomes less useful.
What background app refresh does
Background App Refresh gives selected apps permission to fetch new information when you are not using them. The system decides when to wake them, so an update may occur while you are checking a message, waiting for a train or leaving the screen off. Apps use this for different jobs: a weather app downloads a new forecast, a news app retrieves headlines and a messaging app completes a data sync.
Not every update uses this switch. Push notifications, Bluetooth connections, location services, alarms and Find My can continue in the background even when refresh is off. An app may also combine several methods, which is why switching one feature off does not produce identical results across every service.
Each transfer can involve the app, radio and battery. With several apps updating repeatedly, a measurable drain is plausible, particularly when the signal is weak and the phone must work harder to complete each transfer. The effect is more noticeable with heavy data, such as automatically loading high-resolution social media or video previews.
The feature can also prevent repeated work. If an app updates on Wi-Fi, you may avoid a second cellular transfer later, although iOS already schedules refresh around power and connectivity. Disabling everything is not automatically the best battery move: you may remove small energy savings while breaking a convenience you rely on.
How to turn it off on your iPhone
Open Settings, then General, and look for Background App Refresh. If your iOS version groups apps differently, search for Background App Refresh within Settings instead. You will see a master switch and a list of individual apps.
Turn the master switch off to stop scheduled refresh for all apps, or leave it on and switch off only the apps you rarely need to update. Video players, games, social feeds, shopping apps and photo editors are sensible candidates because their content is useful when opened but not essential between visits. Keep messaging, navigation and security apps on unless you have a specific reason to change them.
Disable the feature for one group first, ideally three or four apps rather than every app on the phone. That gives you a fair test without losing the immediate delivery of every alert. Some people turn off refresh for social apps and keep it for email; others do the opposite because their most active accounts are work email and team chat.
After making the change, use the iPhone normally. Do not restart it repeatedly or leave it charging overnight just for the experiment, because those variables would make the comparison meaningless. Give the setting at least two ordinary days, including a commute and a period when the phone is idle, before deciding whether it has helped.
What changes after you switch it off
Most apps still send push notifications with refresh disabled, so an incoming message or alert can still reach you. The difference is that some apps rely on background work to fetch extra content, refresh a widget or prepare data before you open them. You may notice a delay, a missing badge count or content that appears once the app is opened manually.
| Choice | Scheduled updates | Notifications and app use | Best fit |
|---|---|---|---|
| Refresh on for every app | Apps update content and data on iOS schedules | Alerts are usually delivered promptly and apps stay current | Reliable charging and a preference for hands-off updates |
| Refresh off for selected apps | Chosen apps wait for this kind of update until you open them | Alerts generally still arrive, but some content or badges may be late | Social, shopping, entertainment and gaming apps |
| Refresh off for all apps | Apps wait for this kind of update until you open them | Most alerts still arrive; apps that depend on extra background work can behave differently | A short, measured test before deciding what to restore |
Notifications are the main feature to watch, but data use and responsiveness can change too. An app that no longer updates in the background may use more mobile data when you open it, especially for video or high-resolution images. Offline maps remain available if you downloaded them, and alarms, calls and emergency alerts are not controlled by this setting.
Some apps make sensible choices without refresh, using push alerts and brief network checks instead. If an app feels broken after the change, restore its individual switch rather than abandoning the whole test. Keep a note of what changed, such as a delayed message, so you can connect the behaviour to the setting instead of guessing.
How Australian routines affect the result
Australian city routines can make background activity more noticeable. Sydney commuters pass through tunnels where the network disappears, and Melbourne train and tram journeys can move between busy CBD coverage and patchy suburban reception. An app repeatedly trying to refresh in those conditions may use more energy than one receiving a steady signal. The same applies to a drive through regional New South Wales or Queensland. A shared workday adds another layer: email, Teams, SharePoint and cloud documents may all sync between appointments. For background on those tools, explore Microsoft 365 collaboration. It is worth separating genuinely useful work updates from entertainment apps that can wait until you open them.
Heat is an equally local factor. Summers in Brisbane, Adelaide, Melbourne and inland Sydney can push an iPhone beyond its comfortable operating range, particularly in a parked car or beside a window. iOS may reduce performance, display a temperature warning or shut down unexpectedly when the device becomes too hot. Leaving refresh disabled does not solve that problem; keeping the phone cool lets its battery operate as intended.
Coverage also depends on your carrier and plan. Telstra, Optus and Vodafone all offer 5G in Australia, but handset bands, building materials and tower availability affect real-world performance. A 5G label on a plan does not guarantee a stable connection in every location. For trips beyond the metropolitan network, including remote parts of Western Australia and the Northern Territory, downloaded content and manual app checks often work better than constant background syncing.
Australian Consumer Law protects buyers from misleading claims about product performance. Sellers should not promise that one setting will add a fixed number of hours to every iPhone. If a repair or accessory provider advertises a dramatic battery improvement, ask what they measured and over what period. This matters when a replacement battery is advertised as equivalent to a new one despite clear signs of wear. The Australian market also includes unbranded power banks and replacement batteries, so buy from reputable sellers rather than trusting a low price alone.
Make a battery-saving routine that sticks
Use Settings > Battery to check which apps have consumed the most energy, then compare that with the apps you switched off. Battery usage gives a useful clue, although it does not measure power in watts and does not separate foreground time from every background action. A clearer comparison comes from the same time of day, the same signal conditions and the same screen time over several days.
A routine is more effective than a permanent sacrifice. Turn on Low Power Mode when you need it, especially during long travel or a full workday away from a charger. Low Power Mode reduces some background activity automatically, while turning off Background App Refresh gives you finer control over individual apps. You can restore refresh for anything that becomes frustrating or unreliable.
Battery health matters too. Open Settings > Battery and check Battery Health & Charging on recent iOS versions, then arrange service if the device shuts down unexpectedly or no longer lasts as expected. Heat, age and heavy use affect all batteries, so the settings change works best alongside sensible charging habits and regular software updates.
Turn off refresh for two or three low-priority apps today, record your normal battery level at the same time tomorrow, and repeat the check across three similar days. If the gain is worthwhile, keep the setting that works for you; if it is negligible, switch those apps back on. This small, reversible adjustment is easier to maintain than an extreme battery-saving setup.
