Abrupt on & offs

I recently updated my iPhone 7+ to the latest iOS 15.7 but the problem is, the phone keeps shutting down abruptly and turning on automatically, despite the battery health being on 100%. Mostly I charge it but when it’s like 70-80% it will shut down then automatically turn on showing a lower percentage like 3% then after some seconds increase to like 65%. Is this a battery issue or software related?

iPhone 7 Plus, iOS 15
