What's the input current draw for the Nexus 4? I am trying to find the maximum possible current draw of the Nexus 4 when recharging the battery.


The adapter that comes with the Nexus, supplies 1.2A
The Qi Charging Station needs 1.8A


But I can't find the actual maximum current that can be drawn by the Nexus. I am using a battery pack that supplies around 2A and it only can keep the Nexus running (when playing Ingress), but doesn't really recharge it. I wonder if this is caused by the batteries 2A maximum output or if it's due to the nexus having an upper limit it can handle.
