Cell standby issue(s) typically are seen in areas with weak cell signal. The mobile radio has to ratchet up the transmit power in these weak areas to maintain connection.
i.e. I updated my phone to 5.1.1 this AM. All day, cell standby did not even show up in my battery usage log (I was in good signal pretty much all day). I got home an hour ago (where I have pathetic signal) and within 1 hour cell standby 5%.
I've done similar tests when I was on 5.0.2 and pretty much was able to associate poor signal with the cell standby issue. BTW, I leave VoLTE on.
Source? So far from my experience and others who have this phone it does not matter. In fact it doesn't even matter if you are connected to Wifi or not. As long as the wifi switch is on, as well as WiFi calling/VOLTE if you are affected then Cell Standby will be high.
My friend on T-mobile is doing the same thing I am. Turning off the above features when not needed.
