    We’ve all grappled with whether to close their background apps to save a phone’s low battery. Some people say yes, clearing the background apps boosts your phone’s performance and saves your data. Others, including executives with?Apple?and Google’s?Android team, say no, background apps don’t take up enough of your phone’s resources to affect its performance.?
    
    You might be surprised to learn that both can be true. While background apps may not use your phone’s resources on their own, Android phones and iPhones will refresh background apps periodically by default. This uses your phone’s battery and your data. While background apps refreshing don’t drain your resources as much as screen brightness and cellular connection, stopping apps from refreshing can help conserve your battery and data for when you really need them.
    Low Power Mode for iPhones and?Battery Saver for Android phones both stop background apps from refreshing, too. However, they also pause or change other settings, like screen refresh rate and device performance. These options will certainly save your battery and data, but they cause more dramatic changes compared to stopping background apps from refreshing.
    Here’s how to stop background apps from refreshing, helping your battery last longer and saving your data.
