Hi guys, I've only just bought a Surface Pro 3 (i7, 256GB) a few days back, so I'm new to these forums. Having been using the surface the last day or so, I'm concerned about power usage. I've not really installed much yet, and with only XBMC running, playing video, I seem to be using towards 1% battery per minute. Is this about standard, or should I be hoping for more than that? Brightness is at roughly 30-35% maybe, so quite dim. Thanks.
