A:Answer 6 hrs easy.
8 hrs if turn screen brightness down and enable battery saving and you're doing light browsing and some videos.
I played 9 hrs of Netflix video series continously ( 14 videos, 45 minutes each, back to back auto play ) and still had 1.5hrs left.
If screen is full brightness then battery life will be less.
If you're playing intense game may get 3.5 to 4.5 hrs.
I love it as I code, browse web, watch few videos... and it last at least 6hrs. I charge my laptop where ever I go so it's only when I did initial testing that I observed times above.
If I go mall I find outlet and charge while using. If I go resturant I find outlet. So I've not been in a situation where I used it until it drained.
When I was testing playing Netflix videos, I started videos, went to bed and it was finishing 14th and last video when I woke up. I muted sound which may have helped prolong times, but good thing is it proved system could stream videos continuously without any issues or incidents over wifi and I had 1.5hrs left bases on computer stats. I ran videos with brightness set to 40% or 50% which is bright enough in room...
