Battery Life

Open aleixsr opened this issue 5 years ago • 8 comments

Hello, I've dual boot and I've found that using Win10 I've a lot of battery life that I don't have using OSX 10.14.4, do you have same issue?

Hi @aleixsr, yeah - battery life does not seem to be the best using macOS, but I never really tested the battery life on Windows before so hard to tell if there is a difference. But I would assume so, as one test on the internet concluded "The ThinkPad T480s works overtime. It ran for 11 hours and 29 minutes on the Laptop Mag Battery Test 2.0, which continuously browses the web and a series of videos and graphics tests at 150 nits of brightness."

Using "Action Monitor" in macOS you can identify some battery consuming culprits (that helped a bit in my case) but still, I roughly get 4 hours which is quite poor comparing it to my old X230 with chunky battery extension which got me about 9 hours. 4 hours are still better than my old MacBook Pro 2017, but this is still quite far away from the promised 11.5 hours. @kk1987 @linusyang92 @leafiy Is there something we could do about it?

Yeah, it is exactly what I mean, anybody there?

I am wondering whether this BIOS update might bring us some positive effect - but it is not yet released, just for X1C7. But apparently T480S and X1C6 are also affected. https://tweakers.net/nieuws/157848/lenovo-belooft-fix-voor-throttlingproblemen-bij-linux-op-laptops.html

Thank you very much @philffm ! Did you tried it?

Imho there was no improvement at all but we might be also digging in the wrong direction here... Are you guys also using an NVMe SSD?

Yes, I'm using it.

@kk1987 Does the battery charging limit working? I have T480s i5-8350u with Ventura 13.6.6 and the battery charging liimit is not working, even already set to 80% it's still charging beyond 80% all the time.

Previously on Windows through the Lenovo Vantage already set the threshold to 80% as well
