Your battery health might be less than 70% so better to get it serviced. Also ask them to do a fresh firmware reset so backup your data

Thanks for your information..
I understand but my phone battery was fully okay the day before update.
After update suddenly this problem is happening. Does samsung battery health could reduce suddenly in one day😐?
By the way i get good performance when the battery charge stay in 100% to 31%

Battery is already degraded. The phone is 4 years old. The new software just doesn't show the true battery level anymore. If you still don't feel right you can always do a fresh firmware flash through Odin but yes you still need a new battery pack

Before going for battery replacement or anything. Just reset the phone from recovery mode (it will remove all data so better take a backup beforehand).

Have you done it?? If not then 1st reset all Settings and see for 1-2 days. If it doesn't work then go for full reset as I mentioned before.
