Closing background apps on your iPhone is a common practice, but it’s more likely a waste of time. In 2016, Apple’s senior vice president of software engineering, Craig Federighi, confirmed that closing your background apps does nothing for your battery life. Most of your background apps are essentially frozen, and your system just displays a screenshot of them for consistency. The impact on your battery life is negligible. In fact, closing your background apps actually uses more battery than just leaving them open. That’s because shutting down and initializing an app requires more energy than restoring it from its suspended state in your “background.” Federighi also notes that closing background apps does nothing to improve your phone’s performance. iOS manages your iPhone’s RAM as efficiently as possible by default, and closing your background apps does not optimize anything. In terms of privacy, force-closing apps do nothing to stop companies from tracking you. Apps can still collect your data even if they’re closed. Contrary to popular belief, apps can still track you even if you force quit them. The key misunderstanding here is that force quitting an app is different from turning “ Background App Refresh ” off. Turning off “Background App Refresh” in your settings is the most surefire way to address all these problems.
