Need help with battery life advice for hackintosh laptop

Hello everyone!

I have successfully installed catalina on my asus k401uq laptop (has been in use for around 2-3 years), but my battery seem to last only about 2 - 3 hours? (normal browsing websites alone), and would definitely be lesser if i use xcode etc.

Is that a normal battery lifespan for laptop, or any advice?

SMBIOS i am using is macbook pro 14,2

Thanks!
