Can you try with other fingers?or else you can factory reset it that might solve your fingerprint issue

one ui 2.0 is coming in the end of the 2019 on mostly phones and as you have note 9 so 1 month or 2 month you might get 2.0 update for your note 9.

Brother first check that you have not installed any app that is moded or hacked because these apps drain battery without permission so check carefully or otherwise reset it that might solve your battery drainage issue
