Yeah, the mini itself does not have the same heat so it’s definitely the back of this pack thats dissipating.Thank you.
- I suspect the portal wireless-charge back you purchased is using PD to charge and with such a slim device heat will disappate quite quickly(?) as little room for it to spread out so to speak. The iPhone 4/4s/5/5S would all get warm very quickly when gaming (even the 3GS would) over WiFi (cpu+imbedded gpu+game+wifi … mobile connections being consistent).
Do you feel the same heat when charging the iPhone 12 mini from very low charge level to say 80%?
The other thing I noticed is it wouldn’t charge past 80% even though all icons showed it was. Something weird about that as I took it off and it charged fine with my main charger. I’ll have to test it a bit more. It’s not exactly a deal breaker if I can get it to 80% every time. Seems like it might be able to do that 3 times and getting it quickly off the phone after it does it’s job to give enough charge for the rest of the day is the best scenario anyways.
