Low battery life 3 - 4 hours instead of 9+

[JonnIEnglish]

Good day all,

I recently installed macOS Catalina on my 2018 Matebook X Pro with relative ease and everything seems to be working quite well except for the battery life, which can just stretch to 4.5 hours with no apps open. I have tried everything from battery saving apps to trying to undervolt(which I was unable to do due to an error that I could not fix) but nothing seems to be bringing the battery life anywhere close to the advertised 9 - 10+ hours gnodipac886 claims to be getting in his readme.
I would be very grateful to anyone who could assist with this problem or who knows what to do to increase the battery life.

Many thanks

Jonathan

Hey Jonathan,
What issue did you face trying to undervolt?

[JonnIEnglish]

Hi jonescamilla,

I tried to follow this guide for undervolting using the voltageshift method.
https://hackintoshpro.com/undervolt-mac/

When running the "./voltageshift info" command I got the error: "zsh: killed ./voltageshift info"

I have looked everywhere for a workaround or solution but am not able to find any.
I'm not sure if there is something I am missing or what?

Did you give it root permission?
sudo chown -R root:wheel VoltageShift.kext

Like you had done before just cd and drag the folder over to get the directory. Followed by ↑

It says crown command not found, do you mean chown or chmod?

[JonnIEnglish]

Even after updating permissions it still doesn't seem to be working.

Man, you need to load the kext. RTFM:

Yeah I have been trying to build the kext but I am getting this error now, even with Xcode freshly installed.
