A long time. Longer that my full size GoPros. Near 2:00
Depends on what resolution you are filming in.. I get about 2 hours at 1080p and 60 fps. You can connect a USB battery pack which will charge the camera as it records as well. I have not used 4K video but I think you'd be lucky to get an 45 minutes to an hour at that setting..
I get about an hour and a half of battery life.
The getting a little over an hour.
