Got Acer Triton 500, can't get good battery life in optimus mode

vorob

So on g-sync \ nvidia-only mode i've got 2,5 hours of battery life. When i switch to optimus and have only igpu enabled i'm getting even less, 1,5-2 hours. Why? What's wrong?

Also where can i find latest igpu drivers? From intel page they won't install.

Solved, my issue. I disabled power saving stuff in windows cause usually they don’t work on other laptops. I was wrong. Turned everything back and now I’m getting +4h battery life.

How are you so sure you are on iGPU only? Are you sure you are not using dGPU? Can you send a screenshot where you can show iGPU never being used, even momentarily.

Also note that, usage plotting software like MSI, wake up the GPU and CPU to gather info at regular intervals. So you might want to disable such graph software too when on battery mode.
Disabling the dGPU and forcing all my software using only iGPU stretched my battery life from 2.5 hours to about 5 hours on my G3-572.

Did you try finding the drivers on Acer site for your model?
