It should. Regularly discharging a lithium battery past 40% shortens its life. (You really only get 60% of the rating. You can't change the laws of physics or chemistry.)

and sometimes when i plug it out of the charger at 100%, it suddey drains to 90s%

Due to the way we measure state of charge, we're also measuring the charger. Always wait until it gets to 100%, then wait half an hour. That wa6y, the battery will be at a "real 100%" charge.

I changed the battery, changed the charging base, did a factory reset and still the same problem?

It's not a problem, it's how lithium batteries work.

Quit worrying about the battery. The phone is a smart phone and will take care of the battery just fine. charge it all night and you should be able to use it all day! If it gets charged the phone will quit charging! If it gets too hot the phone will quit charging! If it gets too discharged the phone will cut off!
