I notice in 7.1 location services are allowed on even when an app is forced closed. I've noticed Nike Move is a culprit but when I turn that app off I still get the outline of an arrow which is Find My Friends. I want to allow that app. I'm wondering will it use more or the same amount of battery with Nike Move enabled as well? I.e do they all use the same data so I could potentially have 100 apps using location services and it wouldn't use any more battery than if I only had 1 app using location services? I'm confusing myself writing this post but hope someone understands!
