[Q] Needed battery status help on my tab s 8.4 topic

Hi guys, whats happening on my tab? Today it shows from 100% to 1% in 11 min after charge, and it doesn't turn off though after reach 1% ATM. (screenshot attached)
I did an battery calibration by using apps from playstore, the result still same. What should i do?
Is my battery faulty or something wrong with my system? I doesn't root my device.
Any help or suggestion to fix this would be appreciate
