Battery Drain

[yamyoume]

I close the lid or I clicked the apple logo then sleep, I don't remember
then like 12 hours later at night I open the laptop and battery is daed I plug it in, and it was 1%,

This is very likely related to the "sleep crash --> restart into Windows" issue. ...which then drains the battery.

(When you boot back into macOS, did you see the system crash notice?)

[yamyoume]

I don't have windows only MacOS, and yes I do get that 180 timeout report crash after booting macos again, actually since you've confirmed that you get 3.5 to 4 hours of battery like me, I don't think there is a battery drain, it's just in the guide he says he gets 8 hours of battery life, so I don't know

In my case, I'm wondering if it's because of the following:

1. Display's lowest brightness setting in macOS seems to be brighter than it is in Windows.
2. I'm using an external USB wifi and USB SSD.

I do have the USB wifi, but I'm using the ssd inside the laptop, for brightness, i'm 80% on about 30 ~ 40%, and still getting like 4 hours, depending on how many apps are running, It can drop to 3.5 hours, sometimes I also notice the laptop will be overheating at around 60C and something called "Kernel_Task" or something is using the cpu a lot, a restart fixes that quickly

I hope someone will be able to help us...I'm willing to pay that person if he/she can find solutions to our problems.

I too am willing to pay for better battery performance. Have you tried undervolting to help with the issue? It is what I am currently working on doing.

[Chatbox1024]

I managed to undervolt and up the CPU performance:
#84

Also managed to have smoother and a wider range of display brightness (it can now go as dim as if you were in Windows. i.e. To provide longer battery life):
#89

Just now, I've also enabled the "HWPEnable" option. This seems to work well for me.

(Together with #84 and #89 changes.)
