With a response by Canon stating that I need to return my MIII after a whopping one week of ownership (yeah right), has anyone experienced any battery level issues with the MIII? THIS IS NOTICEABLE WHEN USING THE CAMERA FOR VIDEO.
Specifically, when Canon-branded batteries get between 36%-42% of remaining power via the MENU, the camera turns off as if the battery has no power left. However, if I take these batteries and put them in another camera, they average 1-2 remaining bars. They will not show power in the MIII until after they are re-charged, and even if they are placed on the charger for just a few seconds, they'll then blink with no power on the MIII yet still work fine in another camera (60D, MII). To make this even more bizarre, if a battery in the MIII states that it has, say, 65% left, but I put that battery in a 60D and it happens to read 63%, putting the battery back in the MIII will then read 63%; it will always default to the lower rating, regardless, ultimately implying that the MIII is reading the batteries incorrectly.

Quite simple to test this....charge a battery, go to the menu > battery level and note the % charge. Then, record video and let it continue until it stops at the 29xx mark. Then, note the battery level. Continue recording and repeat until the battery fails and the camera turns off. Note the battery % each time the camera stops recording. If you have another camera that accepts the LPE6 batteries, when it fails in the MIII, see if another camera can pull a charge and note the battery level in that camera.
