We've been seeing this for the last few days. Filing an issue to track it.
Summary: Battery on one of the LG phones keeps on running to 0 → Battery on one of the LG phones in MV keeps on running to 0
I decided to do some monitoring of the battery levels today after :bmoss graciously got things working again. The battery level of the device in MV was initially 100%, now it's down to 87% (after running dashboard tests for a few hours). I did a quick comparison of the charger info against the LG device connected to my desktop, and got the following: Mountain View Device: POWER_SUPPLY_NAME=battery POWER_SUPPLY_TYPE=Battery POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_HEALTH=Good POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CAPACITY=87 POWER_SUPPLY_VOLTAGE_NOW=4011 POWER_SUPPLY_TEMP=338 Montreal Device: POWER_SUPPLY_NAME=battery POWER_SUPPLY_TYPE=Battery POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_HEALTH=Good POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CAPACITY=98 POWER_SUPPLY_VOLTAGE_NOW=4115 POWER_SUPPLY_TEMP=409 Could the 100 difference in voltage be making a difference (I don't know what the scale refers to)? Should we try a different USB charger cable maybe?

Four hours later in Mountain View.... POWER_SUPPLY_NAME=battery POWER_SUPPLY_TYPE=Battery POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_HEALTH=Good POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CAPACITY=76 POWER_SUPPLY_VOLTAGE_NOW=3935 POWER_SUPPLY_TEMP=336 (this is just the phone, nothing else running) Strange how the voltage keeps on decreasing.
A little bit more than 12 hours later... POWER_SUPPLY_NAME=battery POWER_SUPPLY_TYPE=Battery POWER_SUPPLY_STATUS=Charging POWER_SUPPLY_HEALTH=Good POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CAPACITY=21 POWER_SUPPLY_VOLTAGE_NOW=3708 POWER_SUPPLY_TEMP=350 I think it's fair to say that we're seeing a pattern of decreasing capacity and voltage
The problem was that the battery on the LG's in MV just can't keep up when HDMI is plugged in. We resolved this by switching to wall power.
