Has anyone tried a full drain battery test in their digicam in movie mode? Just to see what their camera will do?
I see a lot of quotes on # of pictures, but it just seems that would be high variable: Over how many days/weeks? (self-discharge problem), what file/write sizes, how much time composing shots with LCD on, Flash, etc?
Movies just seemed easier for a controlled test, just turn it on, walk away and see how many minutes. Understanding that digicams have time and card space limitations, you may have to repeat a few times, but certainly less button pushing than with still pix.
If you have done this, can you let us know: camera, battery type/mAh rating, video size and frame rate.
