So I've a 2019 XPS 9570, 9gen i7 with 64Gb of RAM. I've been running Archlinux on this laptop since the very same beginning, it's my workhorse and so far I'm so happy with Arch on it!
However, battery life has been always been a bit of struggling, it was too short for the usage, but latest kernels improved that A LOT. I can get now easily 3h of full working time with the laptop, meaning development IDEs, several docker containers, etc. But, at some point over the last weeks (I think a recent firmware update through linux-firmware), I started having a new issue: if I shutdown the laptop, the battery keeps draining out slowly. If I start the laptop, some hours later, CONNECTED to AC, battery shows 100% charge ok. BUT, if I start the laptop not connected to AC, everything goes ok until KDE shows up, then it shows the battery it's almost drained (the LED indicator in the laptop shows, too), and then it shutsdown within seconds.
I've been checking BIOS settings, etc, but so far I can't see anything wrong.
In grub, I've been always having this seetings:
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet mem_sleep_default=deep"
GRUB_CMDLINE_LINUX="cryptdevice=UUID=601c6f94-f1ed-4db9-9790-a6ac143107e6:cryptroot:allow-discards"
The second one is because my root device is encrypted with cryptroot, of course.
Any idea? It's not a critical issue as I'm mostly working from home, but if I go somewhere else without an AC outlet, I'm doomed.
Some more info:
Linux alpha 6.12.1-zen1-1-zen #1 ZEN SMP PREEMPT_DYNAMIC Fri, 22 Nov 2024 16:04:23 +0000 x86_64 GNU/Linux
Bumblebee is NOT enabled, I don't use the nvidia card, only the Intel one.
I do have a Logi unified receptor for my mouse and keyboard always connected, but I've tested without it, no changes.
Yes, shutdown is in place, it's not hibernating nor sleeping.
Thanks in advance for the help!

Almost 6 years is a long time for a laptop battery; it could just be on its way out, so it may not be anything on your system or BIOS.

Hey @twelveeighty.
I considered that too at first thinking, but it does not match the fact that I can continue using it in the "normal" usage, and it lasts just a bit shorter than before.
In the laptop BIOS, it claims the battery health over 85%, and again, I can use the laptop with the laptop over 3 hours. And this strange behavior started some weeks ago, after a firmware update...
I'll consider anyway changing the battery, will keep you updated.

A final update on the topic; TLDR: you were right.
Since I have a vostro laptop with windows that I use ocassionally, I made an exchange of the NVMEs between one and another. And I can reproduce the issue with Windows, too, step by step.
Battery is dead. Windows reports 64% health, which after 6 years is still awesome.
On the other side, Archlinux running in the vostro shows no issue at all (I'm still typing using it), so nothing's wrong in my setup, just standard issue from age.
A new battery is on its way. Thanks for the tip!
