I've bought a new Swift 3 with AMD Ryzen 5 2500U. Just finished installing the last version of windows 10 (april update) on it and updating necessary acer drivers (especially video, bios, lan, audio, etc).
But there is one problem: 100% battery shows only no more than 4 hours. it keeps changing, sometimes 2 hours, then 3 hours. it is supposed to have 10 hours battery life. Is there anything wrong on the hardware or just missing a certain driver?

  • Do you calibrate the battery? Ideally, this calibration should be three times when buying the noteobook for lithium cells to cycle through the battery and thus show the correct time! Calibrate through windows as this site https://www.gearbest.com/blog/how-to/how-to-calibrate-your-laptop-battery-correctly-and-safely-415
    After calibrating three times, put the power options in balanced mode!

    I've done this, and still nothing changed. Just started the laptop, 100%= 4 hours more, then few seconds later changed to 5 hours remaining, and now at 98% = 2 hours and more.

    Estimated battery life varies by use! For example: if the user uses the notebook to watch videos on youtube, the battery life will be shorter, than if the user used the notebook just to use programs like Word, Excel!
    Can you tell me the exact model of the notebook? Example: v3-571 or sf313-51!
    When calibrating the battery, how long did it take for the computer to turn off completely?

    it is SF315-41

    When calibrating the battery, how long did it take for the computer to turn off completely?
    it varied,, from 6-10 hours, but mostly I let it on without running any program

    I agree that estimated battery life depends on the usage, but not expecting to vary from 4 hours to 2 hours in just few seconds (in my case).
    just to report, now with 93%, 6 hours 43 remaining
  • Check this: go to the device manager and uninstall and delete the battery driver and restart the notebook!

    I have the same model,  sorry to say 3-4 hours is all I get from it.
  • Check to see if upgrading your notebook drivers increases battery life! Although I think this is the normal battery time and it varies depending on the use of the notebook!
