For me, I've had a 10-15% drain (the above mentioned drain was only 16%) for both my EVO and Photon, so it really doesn't sound out of the ordinary. But, I will preface that by saying that, I do have emails pushing directly to my phone (constantly) and data turned on all the time, as well as other apps that run in the background.
Ha, you're right, I should have read that a bit more closely
Does seem pretty high, but not completely out of reason, especially if that person is in a poor signal area; btw, leaving wi-fi on (if you have a decent connection) can actually help with that to an extent as well.
