Try rebooting into recovery, go to advanced menu and wipe battery stats, then reboot.

EDIT: NVM, I think we established wiping battery stats isn't re-calibrating.

Haha, thanks anyway. It's amazing how this concept circulated in the online echo chamber and became "well established knowledge"... yet turned out to be nothing but a myth.

Between my searches and all the responses so far, I'm left to conclude there is no way to recalibrate the battery. Not even doing a full charge/discharge cycle helps (besides, if it's so automatic and behind the scenes, how would one even tell?)
