I like the form factor, screen quality (even though I prefer 16:10), the fact it works, the ports, but I'm lowkey pissed with the atrocious battery life - my new 13" AMD dies after 36h in sleep mode, unplugged and put to sleep at 90%

All the firmware updates are installed, there's nothing concerning in the logs.

Weak and laughable. Not even a few years old xps13s with hundreds cycles are this bad.

For office work, fine, plenty of horsepower, easy to fix, but not for private use at this point.

I assume you are using Linux. Did you do the advanced install to enable S3 hibernation?
