Replaced the battery twice, but it drains extremely fast
I replaced my Samsung Note 10 Battery once I noticed that it wasn't holding that much.
Both my first and second replacements were pretty much useless. In less than 30 mins of normal usage the battery goes from 100% to 0%
That may be what type of battery you use. Batteries have different types of energy inside them. Maybe the batteries might have been used before, too. Try to see what type of battery you use just in case.
