my phone's battery is dying super fast and it won't connect to 4G anywhere..? I mean, when I've been outside of coverage in the past it's shown an icon that indicates i'm outside of coverage, but now there is simply nothing there? And my battery is draining like a mother fucker when i'm not using it? I charged my phone up to 100% yesterday before going to bed, and when I woke up it was on 39%? I didn't even use it once? Does anyone know what could be going on?
