  Discontinued Covert Manjaro Linux to Arch Linux with a script

I'm using arch with 5.10 lts kernel, the hardware is kinda beefy for a laptop (core i5 10th gen, rtx 2060 and 16 gigs of ram, buts still the battery is rated for 3 or so hours under light load). as far as i know there arent any extreme changes to the system. this kinda appeared on its own, but all of the sudden my battery, though not very good, lasts only an hour instead of its 3 or so while doing some easy stuff. the only thing i can think of is a script that converts manjaro to arch, but i had this problem not so extreme before that anyway, also i did play around with undervolting, but that gave me some errors so i abbandoned it. i tried checking powertop and powerstat both saying my power usage is 30-40 watts (on idle mind you) with cpu usage being at 2-5% most of the time. the very weird thing is that even setting my cpu to work on a single core, underclocking it down to 1 ghz and disabling composition, bluetooth and all the unnecessary stuff, the power gets consumed at the same rate leaving me at 1 hour at most of battery life, but right after boot with the super downgraded cpu i can for a minute see that it works and have battery life expected to 20 hours. i tried so much stuff, one thing still being on the table, that is undervolting, but i need to fix some errors on that. i also checked if that is only my install problem, but the battery life sucked even on a live usb, and it isnt a hardware problem as win 10 doesnt have such problem. other than that i tried tlp, i tried cpupower, i tried literally disabling my dgpu and still no success. any help would be extremely appreciated, thanks in advance
