I use Arch (btw) with Hyprland. TLP auto-tune is enabled, auto-cpufreq in power saving mode. Battery life BIOS settings.
Powertop reports for about 6-7W consumption while laptop is idle (wifi on)

Where to look for the problem?

Can you show the output of the Tuneables tab in powertop? That may tell you if any of the settings are in a Bad state while you're on battery.
Also, can you show the output of the following commands?
# tlp stat
# grep -vP '(^\s*#|^$)' /etc/tlp.conf # if you're using this file
# grep -vRP '(^\s*#|^$)' /etc/tlp.d/*.conf # if you're using any of these filesI managed to significantly increase my power savings on battery with the following parameters:

RUNTIME_PM_ON_AC=on
RUNTIME_PM_ON_BAT=auto
AHCI_RUNTIME_PM_ON_AC=on
AHCI_RUNTIME_PM_ON_BAT=autoIf you have an AMDGPU you may need to use different parameters. But I found that despite what the developer thinks, you really do need to tweak tlp to get the most benefit from it.

Thank you for answer. All tuneables are good in powertop (except VW writeback timeout)

OK, that looks pretty good. If powertop doesn't say anything is in the Bad state while you're on battery (except for VM writeback timeout) this may be the best you can do. I did fiddle with vm.dirty_writeback_centisecs a little bit. I settled on the values you already have set, and at least while I was testing yesterday I was able to get it to say Good.
If you have an IPS screen you can also try fiddling with the backlight settings, maybe dim the backlight as much as tolerable when you're on battery; I have an OLED screen so Linux doesn't have that option. However, after DPMS kicked in while powertop was running, I did see my estimated time on battery jump up to 14 hours or so before coming back down to around 6-7 hours (it is a brand new laptop).
How old are your batteries? It may be they're just old so no recalibration or anything like that can be done to improve the charge on battery. You may consider getting a replacement BAT1, unless your x270 Hardware Maintenance Manual also provides a way to replace the BAT0. I know Lenovo sells replacement parts for a lot of their older hardware; they also contract with an official third-party vendor which might also have the part(s) you need.
