Recieved defective ipad and they are not exchanging it repairing it inspite of their warranty policy

I purchased an iPad 11th Gen in January. Since then, the battery has been draining almost 30 percent in 24 hours even when the device is kept idle with every thing off which is approximately 5 times more than the normal drainage expected for the same model.(Normal ipad of same model loses approx 6 percent in 24 hours) I contacted Apple support multiple times regarding this issue and also provided them with screenshots showing the battery drainage. However, Apple support has maintained that this is normal behaviour and has refused to provide a replacement or exchange of the product But reality is that my product is defective because I've compared battery drainage pattern with at least 4 ipads of same model which where purchased earlier than mine and have been used more than mine I request that Apple either replace the defective iPad with a new unit or provide a suitable resolution for this battery issue, as the product is not performing as expected for a device of this model.
