Hi guys I just bought a Surface Pro 3 and so far I'm enjoying it - apart from some rather crappy battery life. At the moment I'm getting around 4 hours. This is with: - 50% brightness - "Hey Cortana" off I don't really want to disable Cortana completely because part of the reason I got the SP3 was because of this feature! I've attached a screenshot of my CPU usage, which indicates Cortana is eating a lot of CPU. I've also attached a screenshot of my battery which indicates Chrome is responsible. If I can't use Cortana or Chrome if I want 8-9 hours battery life, that is pretty sad.
