so my verizon S6 battery life was really bad. I noticed cell standby usage was running 40% 50% maybe higher. I am aware this is a known problem anyway I turned on advanced calling and rebooted the phone and just noticed cell standby is running less than 5 % and battery life seems to be way better. I also noticed the in-store phone did not have the cell stand by usage problem.
