The Go 3 uses an internal 310 mAh battery that recharges through the Action Pod. Insta360 claims the Go 3 by itself has 45 minutes of battery life when measured in “lab conditions” at 1080p at 30 frames per second. I tend to record mostly at 1440p at 30 frames per second, and testing a continuous recording with those settings got me nearly 34 minutes of video.
