This is just one of many myths regarding the tablets. What is true is
that if you turn your tablet off and on *many* times during a day, you
will experience shorter battery duration than if you just put it to
sleep. The reasons are as stated: when starting up and shutting down
you are running the machine at full blast for a significant length of
time, which rarely happens otherwise. However, if you only turn it on
once or twice a day, your battery will last many more days if you shut
it down than if you leave it on, even at maximum power savings.
