In all likelihood, I suspect you have an iPhone ex. Some of the silicon and metallic components may have survived, but the battery, screen, and plastic components are almost certainly defunct. Depending on how valuable the data on the phone was you might be able to extract the SSD and memory and try to retrieve the data (or give it to a firm that does such things) though it may be a waste of time/money to try. If you don’t judge it worth the attempt your best option is probably to see if you can get credit for it put towards a new phone or break it down yourself to see what parts are salvageable.
