Can you check the output  specs for the chargers? This seems to vary
quite a bit. The Nexus 4 charger I have does 5V at 0.7A, the Nexus 10
charger does 2A. Would not be surprised if this makes a difference.

Also wanted to warn folks that if you leave the phone plugged into USB,
then the adb wakelock will keep the unit from suspending. This can be
true even if the laptop its connected to is off. Good way to drain the
battery.
