Issue/Bug Description:
From the first day of upating to PopOS 20.10, I started having battery problems. I have a Thinkpad P1 Gen2 laptop. I never actually had this problem and if not pushing it to extreme usage levels I sometimes get 5 to 7 hours of coding/web-browsing.
But after updating, the battery meter is no more giving right information (just 30mins of charging gave me 90% of battery level, but when I unplug it, it doesn't even hold for 15mins)
Apart from that, it sometimes alerts me of a low battery level but then just stops and continue working with the real (sometimes 70% or even more) battery level.

Expected behavior:
Usually I get 5 to 7 hours of coding/light web-browsing

Same with Thinkpad X1 extreme Gen2 (which is relatively the same laptop except for the graphics card). Looking forward resolution.

Have you already tried clearing out upower's cache and letting it rebuild? Sometimes those stored statistics lead to inaccuracies. You can clear them with the command sudo rm /var/lib/upower/* after which you will need to give it some time to collect new battery statistics.

[rkv0id]

I did that, but still, doesn't solve the issue.
Also, another problem that I noticed, as the battery meter is no longer trustful i think, the system doesn't notify me of a low battery state, it only does when the battery level is critical and it just hibernates after seconds of that notification.

[leviport]

Well the battery meter and that notification only act on the data given to them by upower. Can you post the output of upower -d?

[rkv0id]

Sure, here it is:

I have the same problem in my X1 Extreme gen 2. Suddenly it gives an alert regarding low batter level and after that sometimes return to the correct battery percentage, sometimes it goes on stand by

edit: interestingly I swithed to pop os 20.04 and this issue hasn't been happening

[varomix]

I have a similar issues with in my X1 Extreme gen 2, most noticeable, when I wake up my computer from sleep, the battery is 1% or 2% percent and goes to hibernate, I need to power it off by hard resetting, keeping the power button pushed, restart and then the battery shows the correct amount.
Used to be once in a while, now is almost every time I wake up my laptop, not a great experience.

same with mine in pop 20.10. No issue with 20.04

Have this on the p1 gen 2 too, didn't try 20.04 tho

[prashantlv]

Almost same issue with Acer nitro 7. My battery used to stay with me for 5-7 hours on balanced work on Pop OS 20.04 But in 20.10 It only lasts ~3 hours, even system resources are free most of the time. Can't figure out who is drinking all the juice !!

[rkv0id]

Update: Guess the issue is caused by the Linux kernel 5.8 on Pop 20.10. Updated the kernel to 5.9 (found recommendation on Reddit) and it worked like a charm. Too bad got no response here. Also, I hope they do move to 5.10 or at least 5.9 on pop 20.10 so that we get a more optimized version and solve these issues.

[varomix]

Yes, I tested 5.9 a few days ago, the bad thing is, the current NVidia Drivers don't work in 5.9, need new nvidia drivers, one thing works another breaks :(

[nicolosponziello]

so, since pop 20.04 uses 5.8 but it is fine, I guess there is some sort of regression in the 5.8 kernel in pop 20.10

[rkv0id]

yes I guess so

[callofktulu]

Another thinkpad x1 extreme gen 2 user here. I am having this issue as well. Same as above, Linux kernel update solves the issue but then the os can only work in integrated graphics mode.

[varomix]

I commented about the driver friday here and seems like there's something happening cause it was already tested and ready to go
pop-os/nvidia-graphics-drivers#81 (comment)

we might get it any moment

[varomix]

new nvidia drivers are out and they work, thanks pop

[Davincible]

@RamyK How is 5.10 working for you now? I used to use Pop and get the issue, switched over to Manjaro last week but here the issue also seems to happen, suggesting it really is a kernel issue. I still got the issues on 5.10.15-1

[varomix]

I'm working 5.9 with the new nvidia 460.x drivers and it all works great, this issue is totally gone

[Davincible]

@varomix Alright ill try that again then, got a message that it was EOL so upgraded to 5.10

[varomix]

@Davincible I don't know if the nvidia drivers are compatible with 5.10, they might not be

[varomix]

if 5.9 is EOL imagine 5.8 🤣 also EOL for 5,9 is Jan, 2023

[rkv0id]

@Davincible sorry for the late reply, didn't try for 5.10 actually. Tried with 5.9 and got it working but just moved then from the OS as I can't bare with the risks on this machine, waiting till it gets fixed or a new kernel gets pop's support.

[setuun]

Thinkpad X1 Extreme Gen2 owner here. Can confirm, the kernel update to 5.9.x seems to work. nVidia drivers still working, too.

[bartbatenburg]

Just got an update to 5.11 today, let's hope it's fixed now.

I am on 5.11 in 20.04 and experience the same issue:

Make/Model: Razer Blade 15 Advanced (2020)
GPU: RTX 2080 Super Max Q

Similar results with upower -d, except my energy-empty, energy-full, energy-full-design all read 0Wh, this was working fine back with 5.8. I tossed in the old Win10 drive and experience no issues with battery reporting there (but I do not use Windows on this device).
