High Power Usage Dell XPS 17 9570

Hi! I’m having terrible battery life on my Dell XPS 15 9570, running 5.10 and i3. My battery capacity is ok, so I shouldnt be getting the 1-2 hrs I do right now. I looked at powertop and it says that I am using a high amount of power, so I think the nvidia GPU may not be properly turned off. I am using optimus-select with the aspci call option right now to turn it off. Is the GPU properly turned off? How can I extend my battery life?

Battery stats:

I’m having similar performance with my dell xps 17 9720. Are you using sleep often? It might be related to this topic I opened recently, and nvidia also seems to be the culprit there. Still haven’t found a satisfactory way to fix this though

Thanks, but I don’t think its the same issue. This happens even if I use the laptop for 3 continuous hours, and my laptop is cool when asleep.

well but this tells a different story

/sys/class/power_supply/BAT0/charge_full_design             =   7894 [mAh]
/sys/class/power_supply/BAT0/charge_full                    =   4870 [mAh]

this means your battery capacity has only 61% of a new one left.

Yeah that’s fair. Is the discharge rate supposed to be as high as it is? Since even a new battery would discharge in a couple of hours at this rate

Pleased have a look Dell XPS 17 (9720) - ArchWiki
