I just got a Pro X last week, and I am extremely pleased with it overall. My only concern is that I am not getting anywhere near 11-13 hours of battery. I use the Pro X extensively for teleconferencing, and with the camera on continuously the Pro X will run out of steam in about 5 hours. I am also communicating with Teams, OneDrive, and Dropbox. Are there any tips for getting more time between charges?
