If you are using android Pie update,you will notice your battery might drain fast than ever.. 

There are bug of the android itself on ADAPTIVE BATTERY,Turn that thing off and let the phone settle in around 2 charging cycle than you're phone battery will back in normal.. 

Go to DEVICE CARE ---> BATTERY ----> SETTING 

HOPE THIS WILL HELP OTHERS, CHEERS...!

my note 9 also cannot stand fully one day.. After doing the research at reddit forum they found the bug is on operating system not on samsung.. So give it a try then you'll notice the battery will be better
