Thermal performance Razer Blade 15

Hello everyone, Happy to join this community :) I am planning to purchase the Razer Blade 15 Base Model or Advanced Model and would like to know how the laptop performs thermally and in terms of battery life. If I use the laptop, whether light or heavy use, while the power cable is inside and while the battery is charging, would that ever impact the battery life span? If anyone of you guys have used the laptop, I would appreciate the feedback. Thank you
