Hey just a heads up for anyone experiencing their Hero 3 draining the battery while turned off (over the course of a few hours), the solution seems to be doing a manual reflash of the firmware. When I had bought my Hero 3 I did the automated update thru GoPro but noticed that my camera would go from fully charged to completely dead overnight while turned off. GoPro support had me do the manual flash by copying the firmware files into the memory card and power cycling the camera. Seems to have fixed this.

Thank you for the suggestion, Paul.

I noticed that I was able to get more than 4 hours of run time with a battery BacPac, then something happened and the run time dropped to 2.5 hours. I used the online updater.

I'm using the manual update now, and will see how it works out.

I second your concern...
I dont trust the battery life at all !!!

I'm new to GoPro, but I have seen on my camera that after turned off, it still is blinking blew (remote control on). I have to turn off the remote with the button on the side. If I don't turn off the remote control on the camera, will it not drain the battery?

I'd assume that having the wifi enabled while the camera is off will likely drain your battery though I'm unsure at what speed it would do this. The issue I originally had, I made sure the wifi control was off but it still nuked itself pretty quick.
