Battery drain in Solus is much worse than it should have been (T9800)

I have a fairly new laptop and I transferred an ssd that has a Solus installation to this laptop and updated to the latest. The system works fine, but I have noticed that the battery drain seems to be very high, and indeed much higher than if I run other distros on the same laptop. This is a screenshot for the battery drain in Solus {F7756192} As one can see, the battery drain is around 25W. As a comparison, I installed ubuntu 21.04 and Fedora 34 on the same laptop and checked the battery drain as well. Ubuntu {F7756200} Fedora {F7756207} Ubuntu has kernel 5.11 and consumes about 8W while Fedora has kernel 5.12 and consumes about 12 W. I started using this laptop a month ago and at that time Solus was on 5.11. I noticed that the battery drain was much higher than on other distros with kernel 5.11 (above 30W on Solus back then). At one of the 5.12 kernels on Solus, I think the battery drain was down to below 10W. However, I don't remember at this point which release that was. Later we updated to a newer patch of 5.12 series and the battery drain increased to about 25 W. Now we are on 5.13 series, and the situation does not seem to get better.

Any help is appreciated. Let me know if you need any more information from my side.

Could you reupload the solus screenshot/post a paste with the power estimation for each service enabled? IIRC it may need to be ran as sudo and be left for a while first. Also, this may seem kind of dumb but could you restart the NetworkManager service after boot and see if you notice any improvement? Have you dabbled with using `tlp` at all? Although, this wattage usage does seem quite high and we should try and fix whatever needs fixing on our end.

> Could you reupload the solus screenshot/post a paste with the power estimation for each service enabled? IIRC it may need to be ran as sudo and be left for a while first. #joebonrichie, can you give me some instructions on how to get that statistics? I usually run `powertop` without parameters. When we were on 5.12.x, the power draw of each device is shown on the left column of the `Device stats` tab, but not any more after we upgraded to 5.13.x kernel. I do remember that the `Radio device: iwlwifi` item consumed around 10W when we were on 5.12.x. > could you restart the NetworkManager service after boot and see if you notice any improvement? I tried your suggestion but it doesn't seem to make a difference. > Have you dabbled with using tlp at all? No. The power draws on the three distros were all taken with their default settings. TLP was not installed.

#joebonrichie I was able to get the device-wise power estimation and it is attached here.{F7810173} As you can see, the screen brightness was set to the lowest value while the battery drain for that single item is 17W. It is also weird that the device-wise power drains add up to about 23 W while the total power drain is shown to be above 30 W. EDIT: This is on kernel 5.13.2.

I can tell that my battery life time has been gone down from about 8-10 hours to 1-2 hours in the last months. So I'm experiencing this as well. On my notebook the audio codec/device is at 100% load. Even if nothing is playing. And besides firefox the tick_sched_timer is very high (~450 context switches per second). I don't have any reference. Maybe this helps.

#xulongwu4 since hardware you use is quite recent, did the situation improve with 5.14 kernel? Also is it possible Fedora/Ubuntu installer sets up TLP without user knowing? My 35W mobile Haswell draws 11W when idle and it's been like that for quite a few 5.x kernel releases. The difference is my hardware is dated and I enable powertop (run once systemctl enable powertop).

The difference is my hardware is dated and I enable powertop (run once systemctl enable powertop). No I have not seen any improvements recently. TBH, the battery drain was much better at one of the 5.12.x kernels. However, I don't remember exactly which kernel that was.
