Sorry this isn't a solution, but I wish my 8700 would last even as long as yours does. 2 hours, period. on or off, taking pictures or not, two hours & it's a stone dead battery. Just on the off chance it will help I'm about to upgrade the firmware to 1.3 (I don't really think it will help). After that I've decided to take the camera apart & try to find the problem or possibly just a hack that will let me turn it OFF without removing the battery. I'd as soon have a bunch of bits for the project bin as have to put up with this 2 hour battery life problem. Good luck with your problem, and if I find anything worth while I'll post back.
