One way to do this, without adding any hardware is to check the internal
battery voltage. I'm not sure if it's possible with the standard firmware
v2.0 (it wasn't possible with 1.0/1.5) but you can do it with replacemet
firmware, like BrickOS (formerly LegOS).
I've done it and had a great deal of success. When the internal battery
voltage drops, there is some additional drain, like stalled or stressed motors.
You have to keep the 'normal' voltage up to date, and you also have to
ignore starting and stopping, but it does work.
