m17 R2, battery life?

I'm looking at purchasing a new Alienware m17 laptop. What can I expect for battery life between charges when just doing non-gaming stuff like reading emails, web surfing, etc.  The configuration would be as followed:

9th Generation Intel® Core™ i7-9750H
NVIDIA® GeForce RTX™ 2060 6GB GDDR6
16GB
512GB PCIe M.2 SSD

Thanks,
