laptop very slow on battery

hi all.

i have acer swift 5 (sf514-52t). i7 8550u (kaby lake refresh), 8gb ram, 256gb sata ssd, uhd 620. smbios mbp15,2.

installed sonoma yesterday (havent tried other os yet). everything is working as usual. however, hackintosh is extremely slow when running on battery power. SSDT-PLUG-DRTNIA enabled or disabled no difference. smbios mbp 15,4 + 16,3 tried also no difference.

using istat menus for monitoring. when plugged into charger, geekbench 6 benchmark, i hit 15w quite alot, resulting in around 3200+ multicore.

on battery, only once hit 12w, mostly 2w to 3w. GB6 takes alot of time to finish (and i didnt finish it, so slow). doing anything in mac os also significantly slow. unuseable on battery.

x86platform plugin is loaded in ioregexplorer.

where can i improve this? i read about SSDT power management, dortania page. said "SSDT-PLUG is not required on macOS 12.3 and up." I have not ventured into manual ssdt yet due to this statement.

thank you all.
