Lumia 1520 Phone Function Draining Battery

[Seth Stout]

My battery is draining quickly and it's telling me that my Phone function is hogging up to 83% of my battery life. Anyone know what's going on with this"

Not really but looks like phone = "Sim" related. Did you power off your phone or a soft reset. Or replace your SIM (get it out and then back again). Or if possible place the SIM in another phone to see what happens than to your and the other phone. Or very bad coverage so the phone burns your battery to keep on the network.
