it will like that only if you simply update d your device software by using mobile data or wifi where the one and only proper and recommended method is to flash that firmware by Odin or smart switch or through authorized Samsung service center especially when any big os update or new ui interface comes then this is only proper method..thatswhy Samsung introduced smart switch that people's can get software hole free highest performance of devices but people doing same mistakes repeatedly and facing different types of issues in device...
If the issue still persist, kindly register your concern in Samsung Members app (Samsung Members app > Get help > Feedback > Error report/ask question). Kindly send us the screenshot (which apps are consuming most of the battery). Note: Please send device log files within 15 minutes of issue occurrence along with the exact issue details.
