Wireless charging in M3 makes phone very hot

[SpareHeadOne]

The mat in the car only has a single coil for each phone charger and - as noted in this thread - you get heat when the coils don't line up properly.

I won't bother questioning why Tesla didn't just fit it with dual coils in each pad to reduce this problem like dozens of cheap desktop stands do.

Anyway. In the case of the larger iPhones putting them in the holder upside down lines the coils up much better and you don't generate as much heat.

Thanks good suggestion. Will try that.

Thanks @SpareHeadOne I'll try that next time, I also have the overheating issue.

In my model S my phone might get warm but not hot.

I have a screen protector but otherwise do not use a case. The additional thickness of a case might be a small factor.

I am experiencing a similar issue but only on the right charging pad.

’22 M3LR

Both an iPhone 13 Pro and a OnePlus 9 Pro both get hot on the right pad and normal (warm but not hot) on the left side. The OnePlus gets almost too hot to touch and doesn’t really charge on the right side.

It’s normal for wireless charging.

And some claim that charging EVs can be done this way?

Yes, my IPhone 13 gets quite hot charging on the pad.

It actually happens right now. There is a fleet of taxis in Oslo that only charge with induction charging

Not seen this discussed anywhere yet.

Has anyone else noticed that the wireless charger pads on the M3 make the phone very hot? Also, the phone charges very slowly.

I know wireless chargers are inefficient, and a lot of energy is transferred into heat, but my phone is not in a case, and the wireless charger I use at home charges it quicker, with less heat increase.

A relatively new iPhone S gets too hot to hold just in use after 30 secs, when it shuts down. Abandoned it.

I saw a video where the French built a motorway which had induction charging built in. Somehow it cost more that our psychotic “smart” motorways. Just like our roads, it cost an eye watering amount of money and also just like our “smart” motorways, it don’t work. They abandoned the project - sadly we are continuing at the cost of billions to the tax payer!

I don't recall having an issue with my pixel 4a 5G but with the Pixel 6 Pro now, it's always hot and even draining the battery and throwing heat warnings in Android, will try flipping it upside down but otherwise I just run a cable from the center console. Very disappointed as I was quite excited for the wireless charging pads.

Just upgraded my phone to a S22 and that works fine too and doesn't get hot. I have it in a silicone case too...

 

[aisid]

Tried it upside down in passenger slot, slow to detect wireless and then didn't seem to charge. Then put it right side up in driver slot and.. it worked fine. Maddening.

I had this problem. Bought a USB-C to lightning cable, and plug that into the rear sockets and leave on the centre console. Problem solved.

My iPhone with mag safe and mag safe case gets so hot I get a message that says charging has been turned off.

What model?
I rarely use a mobile except for emergencies but I had to get an iPhone 6S a year ago and it gets so hot it can't be held - this not charging but just switched on. Apparently it's common with that model - and Apple know about it but.....

iPhone 14 Pro. Latest model. MYLR 2023. Guess I'll try using a cable and the center console. Or turning the phone sideways so it doesn't charge.

 

[Durzel]

I have a 13 Pro Max in a clear case (no MagSafe) that charges fine. MagSafe connection to a an Apple charger still works, it’s just not as strong.

I use the personal hotspot and I think this contributes to the problem as it uses more battery, not sure of a solution other than taking it off the charger

Can you disable one side of the built-in charger? The early cars didn’t come with an induction charger so I bought a bespoke 3rd party version for a heady £30! Each side can be plugged in or not so I leave one side inactive and can move the phone over before it hits 100%. The phone gets a little warm sometimes but never what I would call hot.

Nope. Someone suggested having the option to turn off/on which Must thought was a good idea but has never been implemented (assuming it is even possible to individually turn off the ports on the hub it connects into).
