Omg that's awful! I shoot a lot on locations and average around 300-400 shots with previews and all. I play around with the brightness of the evf though! I came from Canon too (1DX and 5d markiii ) and did feel the battery issue but not to that extent! I use 2 xt2 and most of my shoots I use 3 batteries and shoot around 800-1300 photos and still have some juice left! I actually only have 2 original batteries all my other batteries are generics!
