Heavy battery drain in Ubuntu 18.04+Dell 7577 (Preinstalled OS=Windows 10)












0















I have a Dell 7577 bought 2 months back with Windows 10 pre-installed (i7-7th gen + GTX 1060 6GB Max-Q). I dual-booted Ubuntu alongside Win 10.



I am using Dell power manager in Win 10 in an effort to optimize battery life.



My laptop is plugged in most of the time. Once in around 10 days I allow my battery to discharge and charge again to 85%.



Here's the difference indicating the issue:





In Win 10







  • Dell Power Manager Rule: Charge the battery upto 85% and then re-route the power directly to the System. Start charging again when
    power falls to 55% (which may take several days)

  • I hardly heard the fans and the system used to stay pretty cool. I
    never felt any warmth near my palm rest.


  • Usage: Casual browsing and movies. I don't game currently but I ran a couple games for test. I can hear the fans only when the game
    is on but still never felt warm near the palm rest.


  • The battery gives me 3-4 hours (without game)




In Ubuntu






  • Is there any Ubuntu/Linux tool like Dell Power Manager?.

  • Even though I am casually browsing, the fans kick in like the engine
    of a racing car revving or an airliner is about to take off. It gets
    noticeably warm near the palm rest
    and the fans don't turn off they
    stay at a speed where I hear them loud enough working hard to keep it cool


  • Usage: Not started coding yet. Just casual browsing, installing a few things like eclipse, anaconda etc. I'll be using Ubuntu mostly
    for Coding


  • Currently the battery gives me only 40 minutes or so.


Explain me if its an expected behaviour or suggest a solution to optimize battery life, thermals and hardware life w.r.t Ubuntu.



Thanks --Jay
