New M4800: 1 hour battery life?

I have a new M4800 with unbelievably bad battery life. I'm lucky to get 1 hour on battery, sometimes as little as 30 minutes, on light usage (Word, web browsing). 

I've gone through the BIOS and power settings and this is the best I've been able to do. Googling hasn't turned up any solutions, so I'm hoping someone here can come up with a solution. 

Machine specs:


Windows 10

Core i7 4810MQ


Dual SSD

NVIDIA Quadro K2100M

UHD display (3840x2160 native resolution, running at 1920x1080 due to scaling problems)
