I've been thinking about buy one - do you mind giving some details about approximately how long I can expect the battery to last in each of your scenarios above? Thanks.
1:30 seems to be about right, could be less though. I have a GoPro 3 Black Edition and a second battery back. Recently I went snowboarding, took about 2-3 hours of video footage in total (as mentioned above in 150 small files) and cut everything down to a 2 minute video.
So, part of "extending" battery life is knowing when it makes sense to record a scene and when not.
I can still fully recommend the GoPro. It's a fun camera and what I like in particular is that you can point it directly into the sun and still see everything. It has an excellent white balance for amateur video makers like myself.

My Hero3 Black lasts well under an hour with WiFi enabled. I believe the Hero3+ is better - they claim 30% better because of software optimisation and a bigger battery.
I don't find recoding resolution makes a big difference.
