I have a Macbook Pro 13" Retina (Early 2015) running 10.12.6 with a broken battery (Replace now alert) but I still couldn't find a proper battery in my region.

In this case I should shut down the device to move and it seems loosing power also resets the date and time and also breaks hibernate mode which I can use.

I'd like to know is there any solution for forcing AC Mode so it ignores battery (Performance issue due to changing between battery and ac somehow in runtime).

I also tried SMC and NVRAM reset but no chance either.

Please let me know if there should be more explanation.

I noticed the performance issue is because of the battery issue. When battery is not recognized by the OS X86PlatformPlugin (Can be seen in disas, but need confirmation) uses CPUFloor of your device model plist in /S/L/E/IOPlatformPluginFamily.kext/Contents/PlugIns/X86PlatformPlugin.kext/Contents/Resources/.

The issue was battery does not recognized on boot and for MBP 2015 13" CPUFloor==800 which is too low.

BTW thanks to PikerAlpha you can use freqVectorEdit.sh to change your PowerManager plist. I also changed CPUFloor to higher number so MBP can be used smoothly again.
