iPhone 15 Pro Max slow performance after iOS update

I recently updated my iPhone 15 Pro Max to the latest iOS version. However, the device has become significantly slower and I am unable to complete my work effectively. I have already struck the phone twice against the table. What are the steps I can take to resolve this issue and restore its functionality?
