Unusual battery drain, wrong configuration?

Hi, First of all, big up for your work! I successfully managed to install macOS Mojave on my Mi Notebook Pro i7 16GB, everything is working fine (the trackpad is awesome) except for the battery life.

I usually get around 3/3.5 hours out of the machine while doing basic stuff, on Windows this was 6/7 hours. I'm pretty sure there's something wrong in my configuration but I really cannot find out what it is.

In other threads (https://github.com/daliansky/XiaoMi-Pro-Hackintosh/issues/116 and https://github.com/daliansky/XiaoMi-Pro-Hackintosh/issues/97) people claim that their idle power is around 5/10 watts. I just checked mine and it's 18/19 watts idle (with chrome opened and backlight set to 50%, the overall cpu usage is less than 5%).

I'm on the latest BIOS version with the downvoltage patch (https://github.com/Cr0wTom/Mi-Notebook-Pro-Mods) applied, voltageshift is set to -115 for CPU, GPU and cache (same as I'm using on Xtu).

BIOS info:

I haven't tried the CFG unlock patch (https://github.com/Cr0wTom/Mi-Notebook-Pro-Mods/blob/master/Patches/CFG_unlock.cmd) yet. Is it known to make any difference?

Do you have any suggestion?

Thanks in advance, Crypto

Edit: I forgot to add that I'm currently using the cpufriend kext on maximum power saving 800MHz (this is visible on the voltageshift screen too).
