iPhone 12 Overheating during wireless charging

[MattW77]

Yes, absolutely, iPhone 12 felt, in the words of Alan Partridge ‘ hotter than the sun’
I’ve stopped using mine and just plug in a usb cable in and charge it from that!

my car is going in for a couple of recall bits in the next week and that’s one of the things I’m going to raise with them.

including..
1. Randomly I can’t link my phone to my car
2. I’ve lost the charging status from the Porsche app
3. The car a couple of times hasn’t started due to a ‘fault’
4. The 50+ kw DC chargers now won’t work on my car.

apart from that it’s a great car!!

Has anyone figured out the trick to proper alignment for an iPhone 12 Pro? I can get it charging but it gets furiously hot pretty quickly and eventually just stops charging while it tries to cool down. It’s borderline a safety issue.

For me it was: a] turn off wireless charing in PCM. b] Use Porsche branded USB cable.

Advantage is that when using CarPlay – it uses a much higher codec than wireless Carplay.

Edit: Which is another way of saying – I gave up on it!

I agree with this solution. I also have a 2021 Audi Q7 and it overheats my iphone even quicker than my Taycan. Turning off the charging via the PCM will let you use the boost antenna without charging if you need it.

Someone once explained to me that for wireless charging to be most efficient the alignment has to be perfect. This is why Apple uses magnets in their accessories.

The byproduct of a poor alignment? Heat.

That is why I also use a USB C cable and only use the wireless charger in case wife, child, etc. are in dire straits and have no battery for a quick top up to they are not disconnected with the world

I have only used it once. It certainly generated a disproportionate amount of heat compared to the small amount of charge it put in. Presumably relates to poor alignment of the charger relative to the phone. Pity as it’s a nice idea

What do you mean/what is the significance of using a higher codec? Sorry, I am not a computer tech!

Higher quality music when streaming Apple Lossless. Matter for subjective debate if most humans can hear the difference though!

I charge my phone on a Qi charger at home on a daily basis and heat is never an issue. I've test drove a BMW i4 recently and had no issues with the wireless charger in that one either.

Just gave it a go with my Pixel 6 and OnePlus 8 Pro. They charged just fine without overheating so it's probably some sort of issue specific to iPhones.

My iPhone SE 2d Edition will usually overheat after a while while charging on the pouch if if I’m using CarPlay & Google Maps navigation.

Maybe you can try the wireless charging cup, it works very well

I discovered that if I place my 12 pro with the camera facing down towards the back seats the phone no longer overheats. It charges extremely slow but at least it works

Not worth it. Use a cable from rear seat ports - it will charge insanely quickly.

Happens to our iPhone 12 and iPhone 12 Mini, and is not limited to the Taycan. Has also been an issue on the new Defender 110, and Polestar 2. Have had the overheating occur with and without phone cases. Generally works for very short sessions. Heat is a product of charging in general and seems much worse with wireless charging.

I am under the impression that wireless charging is just not very good overall so we tend to just a cable and avoid the wireless charging.
