Try it yourself.

Say your screen uses 500mA, and your fire in sleep only uses 4mA. This means that the time it takes to shut down and power up (say, 90 seconds), would be equivalent to 11250 seconds of sleep time (or about 3 hours). For 2mA in sleep, you get 6 hours.

So, there's a cut-off of a certain amount of hours - if you plan to keep the device off for that long, then a power off is beneficial, otherwise it is better to put it in sleep mode.

Of course, I'm pulling these figures out of my ***, but they're in the ball park.
ZERO juice is sucked. I started my test at 100% and after re-activating it 10 hours later the battery was still at 100%. If 0.001% was sucked, so what?

That's why I ran the test. Others claimed LARGE amounts of juice were sucked in the Shut Down and boot up.
