More testing:
Plugged + Geekbench => bad score
Plugged + Sleep/Wake cycle + Geekbench => good score
Plugged + Sleep/Wake cycle + Sleep/Wake cycle + Geekbench => mixed bag of bad score and hanging.
@Jake Lo can you please take a look when you have time? I much appreciated it.

Hi Hervé, thank you for your time and the suggestions. Unfortunately, it didn't work too.
I have looked into those custom ACPIs and googled them before posting this thread to find anything relates to power control or battery, but to my limited knowledge about ACPI they don't. So I just leave them as-is. Removed the dGPU tho.

Hi Hervé, here the files (including ioreg, DSDT, AppleIntelInfo output). I don't have a Windows running on this laptop, I'll swap the SSD and try to downgrade the BIOS. Thanks again!

Thanks Hervé for editing the wording in my post. Yes, I used the bootpack from that guide.

Hi, my system is Dell Precision 5510
BIOS version 1.16.1
i5 6440HQ
16GB RAM
No dGPU
I'm using the bootpack of @Jake Lo, everything works great so far. Excepts the performance when on battery is much better than when charger is plugged in.
When running on mains:
When running on battery:
Even the VMWare Fusion runs much better on battery (uses all cores). While plugged in, seems like it uses only one core for the VM and it's super slow.
When charger is unplugged, the battery indicator also turns red and says it's low (in fact it's 100%). The performance after unplugging the charger remains the same, I have to reboot on battery to have the best performance.
I couldn't figure out what's wrong, please help me out. Thank you very much!
What I have tried (each line is a separate attempt):
- make a new CPUFriendDataProvider.kext
- disable CPUFriendDataProvider.kext
- disable CPUFriend.kext
- disable SMCBattery
- messing around with BIOS settings
- tried ssdtPRGen
Nothing worked so far. I also notice the number of "P-States" reported by the AppleIntelInfo is quite low, ranging from 6-10 speed steps. The CPU does run at 3.2GHz boost tho.

I've downgraded the BIOS to 1.15.0, the result is still the same
