For every instruction in the original NewtonOS, Einstein runs about 200 to 300 instructions on the host machine, needing about 200 to 300 times as much power. Then again, during sleep cycles (and NewtonOS makes great use of all kinds of power naps and sleep cycles), the emulator is smart enough to let the host system sleep as well.
So as long as you do simple stuff (like viewing the calendar), battery usage should be reasonable. If you use the CPU a lot (hand-writing a novel), the impact will be quite big.
