Guyss, please help me out!!! I'm having a debate with myself whether I should change my laptop or not

I've had this macbook pro 15 for like 5 years and it's driving me crazy.

I draw on clip studio paint, and the battery runs out really fast, like, in 4 hours the battery will go from 100 to 0!!!

And when the battery is low, the brush stroke will lag, resulting in square-ish and unwanted stroke

Today I use adobe character and adobe media encoder to make video but battery runs out from 100 to 0 in 2 hours!!

Was that normal??

I've brought my laptop to a service for 3x and paid a fortune for each service, but battery still drains out really fast

People said that macbook pro is the #1 laptop, but I find it hard to believe, I need a long lasting battery laptop since I work fulltime on videos, comics, and animations

Also lots and lots of applications are not available on mac, which is why I'm thinking about changing to windows, I think that's better than spending more money on services

My friends suggested that I change to ROG, since it's way stronger than mac

But should I change it?? Or do you guys have any other laptop in mind that suits my needs??

Plz help!!! Thank you
