If you have an iPhone and recently noticed that your battery isn’t lasting as long as it used to, you may not be alone: Many iPhone owners are claiming that they’ve noticed Apple Music is responsible for excessive battery drain.

According to complaints on both the official Apple Support forums and Reddit, first spotted by MacRumors, users with iPhones running iOS 13.5.1 and iOS 13.4.1 claim background activity from Apple Music is sucking up an inordinate amount of battery, resulting in battery usage upwards of 50% in some cases.

One user on Apple’s Support Communities posted a screenshot of their iPhone’s battery usage, showing a large spike in recent background activity with Apple Music responsible for sucking up 53% battery in one day.
