Detailed description:

The battery life sucks on this one, I was promissed 8h+ by the seller, bought it just a couple of months ago, my records is 4h. 100% loaded it says 2-4h... now I have uninstalled everything, turned off everything.. even when doing nothing with no software open, it wont last more then 4h.. and am I not supposed to work on it??? I got an 6y old Sony Vaio that I still gets 15-16h on, new it was...

Cant have the mx250 activated, because if something use it, the fans starts speeding up as hell and the laptop gets smooking hot..

What am I supposed to do with this crap??? Work... 1-2h.. using it with charger.. then it also gets hot as hell and fans is so fucking disturbing..


  • Hello raspelin,

    May you double check if your BIOS and Windows are all up to date?

    and then may I have a screenshot of the task manager to see what could be using more power than we expected?

    Also, what is your screen brightness?

    Thank you.

  • Yes BIOS and windows are running the latest updates, and this problems has been on all versions, since I got the computer in august/sept 2020...

    Using no sound and lowest brightness and battery saver... now 97% battery and computer says 2h 13min...

    Im a computer engineer/developer with 20y+ experience, and I have turned off all windows functions and now have no installed softwre mot then Opera, that I tried if Edge was the problem... have also tried chrome and firefox.

    How do I do to get the 8h+ promissed? 2-4h is when doing nothing.. if I run software that I need for work.. RDP.. Visual studio etc.. then it is 1-2h..

  • How was this 13,38h done? Is it something wrong with my laptop?

    Now I cant even use it until lunch...

    False advertising or did I got a bad unit?

  • Intel(R) Core(TM) i7-10510U CPU @ 1.80GHz  2.30 GHz

    16,0 GB (15,8 GB går att använda)

    I have the version with i7/16GB/1024SSD

  • Do I need to turn off the screen maybe to reach 8h?

  • (the main screen 14"... the screenpad is off,, cant use it then batterylife drains quicker then hell and fan goes max)

  • Latest version of Bios.. 306... (System language is Swedish)

    There should be an asterisc on that page saying in what conditions they achieve that running time. Usually, a laptop does not last that much, at least I don't know of one that would last as much and also do some work on it. My UX581GV lasts around 1 hour and 30 minutes max, so I mostly keep it plugged in, which makes sense considering that it has the RTX2060 graphic card and the I9 9980hk procesor on it.

    It is common for companies to hype on some things that work only on paper. Of course, it's not normal to to do, I'm just saying that it's a common practice for non-european companies because it's difficult to fine them.

  • Yes but when the reseller promise 8h+ full day of work, and it is written in the specs on, then we can not accept 1-2h? It's to big of a different to be okey. Now I have to use my old laptop and RDP into this new one, so it can be plugged in.

    Im not playing games or doing anything heavy, then I understand if it will be less.. but even when doing nothing with everything off, 1/3 of the promissed time..

    The reseller also knew I was to buy it for work, no one works with everything off just starring at it with a black screen.

  • Hello raspelin,

    Then may you run battery report? see if the battery is having expected capacity and charging as expected?

    Please refer to our battery test configuration at the bottom of our official website.

    • Battery life test configuration: Intel® Core™ i7-10510U, 8GB RAM, FHD display, 512GB PCIe® SSD. Battery tests conducted by ASUS in July 2019 using the MobileMark® 2014 Office Productivity scenario. Test settings: Wi-Fi enabled, display brightness set to 150nits, ScreenPad turned off. Actual battery life may vary depending on product configuration, usage, operational conditions and power management settings. Battery life will decrease over the lifetime of the battery. With ScreenPad turned on, the battery life was 10.1 hours.

    Thank you.
