[question] What is the battery duration on the 4K 9570 version?

[toonvanstrijp]

Last time I tried this repository I had a lot of troubles to get the battery to perform well. That time my battery lasted for 2 hours... and the fans where also spinning constantly. Is this repository well suited for a daily usage?

[LuletterSoul]

Not so well suited for a daily usage, I got about 2.5 hours battery duration on 4k model.
What the longest battery duration can you get from other repositories?

[toonvanstrijp]

I read somewhere that the 1080p model got a battery duration for 7 hours.

I was just wondering why we lose so much battery cause in linux I got 8 hours or more with the 4k model. Maybe the graphics card isn't disabled properly?

[LuletterSoul]

I have no idea.The most possible thing that can cause high energy consumption should be the discrete card.I will do more tests and figure out how SSDT-Disable-DGPU.xml works.

[LuletterSoul]

Finally, I found SSDT-Disable-DGPU.xml it do work to disable the discrete graphics card, so disappointing, it seems to be not related to battery usage.

I get around 2 to 2.5 hours on the 4K model and have fans constantly running.
Undervolting by 105mV (i7) using Volta seems to have helped a bit. Activity monitor shows around 5 hours estimate at 100% charge. Don't know if it would last that long though. I will test for a couple days.

[toonvanstrijp]

Awesome. I hope we can tweak it a bit so that it runs much closer as Ubuntu does. Cause there I have 11 hours on a full battery :).

[LuletterSoul]

The new version could gain 5+ hours if the machine executes tasks slightly.But it much far from amazing 10+ battery duration. : ). Anyway, I feel fans become more quiet using current version based on BIOS 1.11.2.I haven’t use undervolting mehod yet.

I got much better battery life by switching layout id to 72 instead of 30. See here

Any progress with this issue?

Can you use headphone with layout-id 72?

Did you actually use Volta? Apparently (according to its site) the undervolting functionality only works with Hashwell and Broadwell (2013-12015) processors so it won't apply to the Caby Lake CPU in the Dell XP 9570.

You can use voltageshift to disable turbo boost and limit power

Yes, I used Volta and seems to be working. You have to disable csrutil from recovery as instructed on the faq page.
