Hi , I am facing a strange issue on my laptop. I replaced my laptop battery just 20 days ago because my previous battery life cycle went down to 17% . My laptop is fairly new just 2.5 years old.
battery has been changed because first 8-10 months it ran on windows and on a HDD , later after change to linux i switch to ssd with high capacity new 8 gb ram fitted on top of it.
but still with the setup with 12 Gb ram and ssd , only lite programming no media at all lasts my battery only 1.30 hrs max. whether on windows got 4 + hours with heavy multitasking. why?.
the new battery is from real OEM.
I have formatted my ssd and reinstalled arch with no additional software but no improvement. why?
CPU = AMD Ryzen 2500U.
Manufacture = Asus
RAM = 12GB
No extra GPU only built in
battery new = 20 days old
Desktop Environment = KDE plasma latest.
Linux specially bare Arch Linux has to took less power, then why this issue?
can you please help me?

Read the whole Ryzen article: https://wiki.archlinux.org/title/Ryzen, especially the microcode part.
Powermanagement under Archlinux is described under https://wiki.archlinux.org/title/Power_management.
Check this, too: https://wiki.archlinux.org/title/TLP

I am going to apply this because TLP method does not help a lot
and I need some automatic management behind the stuffs.
anyway thanks for the help.
to be noted all of the other mentioned settings I have done anyway or installed anyway form the first

In my experience you can't get to the point of idle(!)-power-consumption as Windows (at least with mobile AMD hardware).
Especially your Zen1 may have disabled mwait-instructions* by the firmware and the Vega still got no gfxoff-support by default (AFAIK).
Also the violation of standard-acpi-implementation by the firmware may cause higher power-consumptions.
So IMO 10-15w idle is the best you'll get (whatever "lite programming" really means).
*In that case, "idle=halt" via grub-cmdline saved some watts for me.

CPU-utilization != active+working support for power-saving-functionallity
