Today’s smartphone batteries may hold charges longer than ever before, but that still doesn’t mean much in the face of constant Snapchats, Facebook updates and Instagram photos.
If keeping your iPhone alive throughout the day is a struggle, it may be less about the actual battery and more about the software that’s being run on your phone. Fortunately, Apple provides a way to check on which apps are sapping your battery’s life the most in the latest version of their mobile operating system, iOS 9.
Head to Settings -> Battery and then scroll down to Battery Percentage for a list of apps and how much of your battery’s power they’ve been consuming over the past 24 hours, or seven days if you toggle the option, in descending order.
On the same menu, you can also toggle Battery Percentage to have it displayed on the top right of your screen next to the battery icon. Clicking the clock icon on the right will show you the length of time your apps have been running.
If you notice any apps that are costing too much battery life, you can turn off Background App Refresh — a feature that lets apps automatically refresh while in the background — for them by going to Settings -> General -> Background App Refresh to help alleviate their drain.
