How long is the battery life?

Q: How long is the battery life?

A: For both the Black and Session models GoPro have confirmed that with limited features turned on (Wi-Fi/Auto-Upload etc.) at Full HD and 40FPS the battery life is just under 2 hours. 

With a lot of features turned on the battery life will drop down to roughly 1 Hour 45 Minutes. 

When using 4K recording modes the battery will last for roughly 90 minutes.
