I have a Tuxedo InfinityBook Pro 14 gen 6, with 3k display, i7 13370H and a 53 Wh battery. The battery life is… not so great. After watching a 2 hour movie with an external full HD display, the battery loses around 30/40%. Using the laptop display, it would be more than 50%. The average battery life is around 4 hours, but if you tweak the parameters with Tuxedo Control Center, turning off some cores and the fans, and lowering the CPU frequency, it can last more than 6 hours. I feel like this model, with a new CPU and a bigger battery (almost doubled!), should do much better.
My model (the InfinityBook Pro 6) has two fans: when they ramp up they are clearly noticeable, but I don’t think they are that annoying. I feel like the noise is acceptable and justified by the laptop’s thinness, but that’s just my perception and it could be that the thermal department has changed through the generations.
