This could lead to slow charging or no charging. Hence, always charge or keep your iPhone in cool or ventilated areas only.
Another case of inflated temperature could be that you’re continuously using your iPhone while it’s getting charged & also have multiple apps open side by side. This would also result in slow charging, so plug out the charger, keep your device aside and let it cool down for some time. After 10-15 mins, check the ideal temperature; if it’s between 16°C to 22°C, then only plug in the iPhone charger.
