Battery discharge rate not changing at all


I have a Intel N3450 mini laptop, the discharge rate in power statistics doesn’t change at all, it stays at 3.8WH no matter what I do. TLP has been installed and I used sudo tlp-stat -b to check again, it is still 3.8hw.

I don’t think it is possible even under heavy workload situations.

Please advise, thanks a lot.


3.8W is amazingly low!

Power stats come from the kernel. If its not updating correctly that is a kernel bug.

Best report this to launchpad

ubuntu-bug linux

I have a Jumper EZbook 3 pro mini laptop, I turned on my fully charged laptop at 15:50, it is now 17:33 and battery level is 84%。Just writing emails and surfing websites. Actually, 3.8wh is achievable for this laptop as I have seen the same in tweaked windows 10 and other linux distros.

I will report it, thanks
