Battery life dropped drastically after updates

Hi, as per the title, after latest updates my battery went from lasting ~10 hours to ~2 hours.

I have an Asus Zenboox UX533 laptop. I am using TLP to manage my power settings and I didn't touch its settings in a while.

I don't know which update in particular caused the issue, it seems that the only packages that could have had a saying in this are

[2021-04-02T13:07:12+0200] [ALPM] upgraded linux (5.11.10.arch1-1 -> 5.11.11.arch1-1)
[2021-04-02T13:07:12+0200] [ALPM] upgraded acpi_call (1.2.1-40 -> 1.2.1-41)

But of course I'm not sure of it.

Is someone having the same issue?
Also, anyone has any suggestion on what to look for?

Re: Battery life dropped drastically after updates

I'd start w/ powertop to see what draws the power and also check the CPU frequency since it likely just never rests.

Then  you could oc. just install the lts kernel to see whether the kernel udpate is the cause.
