I have noticed when I place my phone on the wireless charging area, it feels very warm. Yesterday my phone shut down because it got too hot. Since I was using maps to navigate in a city, it caused a moment of alarm until I could pull off and use “hey Lexus@ to guide me.
what is going on with this overheating issue? My phone never gets hot unless it is wireless charging in my NX 450 h+. Any thoughts?

 

Are you navigating with the phone?
How many apps are running? Try closing any that aren't being used.

 

We no longer have a 2nd gen, and the one we had didn't have the wireless charging. Oh, and we use Android. All that being said, when we wireless charge at home, it makes the phone warm, and when we use navigation on our phones, it also makes the phone warm. Combine that with the fact the charging cubby is so far down inside the car and the warmer weather, I'm not surprised it all ads up to the phone getting too hot.

 

Yes, in fact I was using navigation. How interesting! Thanks for the tip.

 

And people say "Drive Connect" has no use?

If you need to charge while using navigation, use a plug in cord instead of charging plate and it won't heat up and thermal trip.

Good luck and be

Thanks, I will use the plug in cord from now on!

 

I came up with another solution. I bought an Apple MagSafe charger and taped it to the car using two-sided 3M tape. This is super secure, the phone does not slide around at all, and it never heats up, and I use CarPlay (e.g. Apple Music) every time I drive, and Apple Maps almost every time I drive.. Here’s a photo.

 

Clever!

 

Yes. The heat buildup is actually a sign of the inefficiency of wireless charging. The induction coils gradually heat during wireless charging. If this is really pronounced, it can also reveal that the charger simply isn't fully compatible with your particular device, or your phone case may be too thick for efficient transfer. This heat transfer isn't as pronounced if you don't use a case. Bottom line, wireless charging is going to heat up the device to some extent no matter what, and it gets worse if charging in less-than-ideal conditions. Using the phone at the same time, especially if the screen is on, just adds to the heat buildup. If the phone is pushed into that enclosed cubby in the dash where there is little to no ventilation the heat will build even faster. Charging with the cord is obviously not as convenient, but it shouldn't overheat your phone when using a compatible cord.

 

As you will see, I started a thread about that very thing, using the auxiliary and it will only charge at 5 W, see my thread and I’m hoping some people have some suggestions. Thanks.

 

To get full 30W you realize you need to plug it into a USB-C port. The Apple MagSafe charger mentioned by @Dkaplan only gets 15W connected to USB-C

corrected for clarity @LiBeRtAs , I should have said USB-C instead of USC originally

Are we talking about the MagSafe wireless charger in the car or the auxiliary cigarette lighter that I’m using, both are much slower than 15 W for me anyway, but as per our friend, he reminded me we have a USB-C in the back seat.

The wireless charger is very slow, I’m not sure what you mean by USC but of course I know you need a USB-C charger and cable to get the higher wattage. That’s why I bought an Anker USB-C auxiliary plug-in that goes into the cigarette lighter and the Best cables they make thinking it would be faster than 5 W, but it is not for me. I have a brand new Anker USB-C auxiliary cigarette lighter charger with two ports. I believe it is 60 W and brand new Anker USB-C cables 60 W.

For clarification in my 2022 model there is no USB-C port in the front seat(that I can find anyway.) There’s a USB-A and the other one I forget what it’s called. Micro USB – B
I think.


These are what I’m using in the auxiliary, cigarette lighter:

Anker USB C to USB C Cable, Type C 60W Fast Charging Cable (6FT, 2Pack) for iPhone 16 Series, iPad mini 6 and More (Black)

Anker USB C Car Charger, 40W 2-Port PowerIQ 3.0 Type C Adapter, iPhone 16 Car Charger, PowerDrive III Duo with Power Delivery for iPhone 16/15/14/13

 

charging rates: (from Google)

The fastest charge iPhones can handle depends on the model. The iPhone 8 and later support up to 20W, while the iPhone 12 and later can handle up to 27W with MagSafe. For wireless charging, the highest wattage an iPhone can get from the Qi wireless charging pad is 7.5 watts. Apple recommends 20W or higher for fast charging.

Charge on Don Quixote

My question is still outstanding. Anyone who has used the auxiliary cigarette lighter with a USB-C charging device. Are you able to get higher speed than what I’m getting anybody who’s tried it?
