Sever battery drain 2020 Blade Stealth, dGPU?

I had this problem a while ago and managed to fix it, but the only solution I had was to disable the 1650Ti in deice manager, and most of the time this wouold push my estimated battery up to around 6-7 hours when in a battery mode favouring longevity. Recently it is doing the same problem again, but it seems to be draining still very quickly, and sometimes as quick even when I have force disabled the dGPU? If there is a way to fix the issue with the dGPU to start, then that would be great, as I normally connect to a Razer Core when I require graphics power, but having the battery drain inside 2 hours seriously limits what I can do with my device I bought it around September 2020 so it's definitely not an issue with the battery itself, especially as I managed to mitigate the problem before... any help would be greatly appreciated :)
