Xiaomi Yi Camera Battery Life When Shooting At 1080p / 60FPS? 30FPS vs 60FPS?

Greetings,

I just recently bought myself a Xiaomi Yi action camera. Some would call it the "GoPro Killer". My question is, what's the duration of the battery life for the camera? I'm about to record some of my performances soon and I don't want it to die mid-show.

Details:
Camera: Xiaomi Yi
Firmware: 1.2.13
Battery: 3.7V 1010mAh Li-ion
Preferred recording format: 1080p / 60FPS

Also, what's the difference between 30FPS and 60FPS if I do not use to wish slow-mo effects on editing later on? Does it affect the sharpness, colour, blurry movements or so on.
