Background App Refresh is a feature on iPhones that allows apps to update themselves with new information from the internet even when they are not actively being used. This means apps like weather, news, social media, and cloud storage can automatically load new content in the background, making them faster and more responsive when you open them. Users can adjust this feature in the Settings app under General > Background App Refresh. They can choose whether apps can update over Wi-Fi only, Wi-Fi and cellular data, or not at all. Whether or not to use Background App Refresh depends on the user’s needs. For apps that require real-time updates, such as those related to travel, navigation, file syncing, or productivity, it’s generally a good idea to keep the feature enabled. However, for apps that aren’t used often or don’t need constant updates—like food delivery apps, most games, or website browsers—turning off background refresh can help save battery life and reduce data usage without significantly affecting the user experience. It’s important to note that disabling Background App Refresh for an app does not stop notifications from appearing, as long as notifications are enabled and not blocked by Focus modes. However, users may notice a slight delay when opening the app and loading new content. For those looking to conserve battery, Apple also offers Low Power Mode, which disables background refresh for all apps. This is a useful option when the battery is low and the user wants to extend its life. In addition to Background App Refresh, users can further control their data usage by managing which apps can use cellular data. This can be done in Settings > Cellular, where users can see how much data each app uses and choose to disable mobile data for specific apps entirely. Some mobile carriers and Wi-Fi networks also offer a Low Data Mode, which limits background activity to only the apps currently in use. Combining these settings with Background App Refresh gives users greater control over how their iPhone uses battery and data, allowing them to tailor the experience to their preferences and needs.
