-Running the CPU at full speed on a G1 will drain the battery in a few hours.
-Running the CPU at full speed on a G1 while the device is charging will slow down the speed at which the device recharges. -Running the CPU at full speed on a G1 for any extended period of time will make the device hot to the touch. JBQ PS: pushing to the extreme, which doesn't seem to be the case here, it's possible to make a G1 draw so much power that the battery almost stops charging or even discharges while the device is plugged in, especially when charging over USB which provides less power than a wall charger. The CPU alone isn't enough for this, but if you start to add up enough power-draining peripherals (network, screen, GPS, accelerometer) you could be consuming several watts.
