Short battery life after replacement

So about a month ago i decided to replace the original battery in my Note 10, as it wasn't holding enough charge to last a full day.

I ordered replacement battery straight from ifixit, hoping that a more recently produced one would be less degraded then an original one that most likely sat in a warehouse for past few years.

Well... the surgery was a success and the patient is still alive, but the battery life on a new part is about the same as on the old part....

I'm pretty sure i performed the callibration properly, and my usage habbits are pretty much the same for the past two years....

Could the new battery be more degraded then i thought? Or could it be some user error on my side?
