Qi Wireless charging and HEAT. What's normal? topic

I've been experimenting with Qi wireless charging and love it, with one exception...........the intense heat generated by it.

I've tried several charing pads coupled with a Qi receiver/insert(of the slim variety, that fits inside the OEM battery cover without extra bulge), and all combinations have generated CONSIDERABLE heat. Not just warm...but VERY hot.

My obvious concern is with the phone, and any depreciation/reduction of lifespan. Is it normal for the battery to get this hot? Will it affect my phone in the long run? Should I use the official OEM Qi charging battery cover in place of an insert receiver(I shudder at the thought of a thicker phone).

Appreciate the feedback, in advance. Thanks!
