I check the battery health on the galaxy S9 using the dump state log check. I don't know the exact name of procedure. So should I replace the battery the life is pretty bad I have to charge it three times in a single day, I am reluctant because this is a original battery.

The phone is still going from and also should I install a custom ROM, and are there any stable versions of lineage OS, meaning that everything on the phone works fine after the flash. I need some opinions

Should I install lineage os the Galaxy S4? Model is GT i9505.

I am aiming for android 7 or 8. So would that be possible?

I already installed Lineage os the S5 (android 9), that was my first install using odin.

So what should I do with the S4 lying around?
