Hello I had first gen Surface Pro and had about 3 hours of battery life, and I read all that comments that people get ~6 hours from it. I tried all recommendations but never got more than 4 hours. Now I bye the second gen device, it had 33 cycles on battery, so it’s alive. However, I can't get more than 5-5:30 hours from it, by reviews and other users claims about 8 or even 10 hours. So what I do wrong? My average usecase is MS Office + Chrome , WiFi, 30% brightness and type cover connected. Not mentioned the games, I think device survives about 2-2:30 hours of gaming (I played recently Far Cry Blood Dragon runs good in 720p) Sorry for my English.
