Question about the 2019 and 2020 Razer Blade and Stealth battery life

Hey guys, was thinking about buying a blade or stealth for college as well as some gaming use, and I was wondering what kind of battery life your guy's machines were getting (both undervolted and as they come) while doing regular productive work. I've been getting a variety of answers from my research, so I would really appreciate the help of some regular people using their laptops as they would!
