Not all iPhone users realize that, depending on how your phone is configured, Facebook can track your location at any time—and it’s likely draining your battery.
It’s not surprising that Facebook does this, since the company has a history of tracking users when they’re not aware, and that the app can track you when it’s off is clearly stated in the app itself. But the question of why the app drains your battery started as a real mystery.
On Thursday, Circa co-founder Matt Gilligan wrote on Medium that the Facebook app on his iPhone was running in the background, even when he turned off background refresh for the app, which is supposed to shut off most app functions. The app accounted for 15 percent of his battery drain as a result.
