Oh yeah turn off wifi. I have a Drift Innovation Ghost, and have the on board screen. I get about 4 hour of full time recording out of mine. My older Drift HD used to last about 8 hours of recording, which was enough for a full day motorbiking. Now I carry a spare battery and swap out at lunch time.
