U can probably do a bit of tuning using ur own kernel compile if u want, but using amd power tuning options in kernel is easy. Just need to mod the grub.
Check amdgpu kernel driver options , amd pstate control can help a lot.
Then it is important to minimise the screen brightness (screen has 500Nits, so very bright and consumes a lot of battery power) and you can also turn off the keyboard backlight. In addition, you can disable bluetooth if you are not using it. As for suspend. How long do you have the laptop in suspend and how fast does the battery drain?
I have recently bought a 14" Intel-based TongFang from LaptopWithLinux, and my experience is similar - pretty much everything is fine apart from the battery life.
I also had a Macbook as my main machine before, it wasn't even a new ARM-based one, and you could still close the lid, forget about it for a couple of days, then open it and continue working. On this setup I'm losing close to 10% an hour of the battery charge, so if left overnight it will require a top up, and won't last like this through the whole day.
The battery life itself is also not great, I think it's about 4 hours of real work without doing anything specifically intensive. The cooler also kicks in more often than I was used to with Macbook. By the way, installing Slimbook battery utility helps with battery life, its regimes are doing a better job than what is built in in my Pop_OS.
That said, I am coming to terms with this problem, because it is roughly the same on Windows machines in the same price range (around £1000) as well. It's just that Macbooks are exceptionally good, not that these Linux laptops are exceptionally bad.
I've always struggled with Linux laptop battery, it's unfortunately never been a strong point in my experience, but its decent enough. System76 is actually based out of Colorado where I'm from! I've used https://www.sagernotebook.com to order all my linux laptops, although they weren't specifically built or had official support for linux, they generally worked well out of the box.

Asked the support for help.
This is what they told me:
Q: Is there a way known to your company to make the battery not drain so fast? Its bothering especially that it drains when the lid is closed.
A: First of all, it is important to install the necessary drivers. You can find our repository here: https://comexr.github.io/
To add it to ubuntu open terminal and run:
wget -qO- https://comexr.github.io/comexr.asc | sudo tee /etc/apt/keyrings/comexr.asc >/dev/null
Run:
echo "deb [arch=all signed-by=/etc/apt/keyrings/comexr.asc] https://comexr.github.io/deb stable main" | sudo tee /etc/apt/sources.list.d/comexr.list >/dev/null
Run:
sudo apt update && sudo apt install lwl-drivers yt6801 -y
