Do you have any taskillers? battery apps? ram apps?

I got this problem too. 19% never drain for 3 hours with wifi running without stamina mode n other chat application running.
When place to dock charger, it showing 29%.
Thing goes wrong when I turned off the phone, left for half n hours, get back n saw battery indicator showing not fully charge. I boot up phone then it go for 100% charged.

This should explain how Stamina Mode work

How you explain when charging with phone turned off. The indicator showing around quarter to fully charge the battery. When turn it on, its showing 100% fully charged. This is not explaining stamina function.
