Wireless Charger Overheating iPhone

[bad company]

I had a BMW wireless charging pad on my 2017 540. Occasionally in the 3 years of ownership it overheated the iPhone which stopped working until I took it off the pad to cool down.

In March this year I changed to a new 340 and hoped that the charging pad would have been improved. The reverse was true, my iPhone now lasts no more than about 20-30 minutes on the charger before freezing (strange term as it actually gets too hot). I run Apple Car Play with Waze which may be a factor but then I also ran that on the previous car.

Anyone had similar issues or know of a fix?

Get a new phone, or rather have that one repaired

You really think it’s the phone rather than the charging pad?

Phone in a case?

Yes, of course. Otherwise the phone would be damaged.

Do you think there’s any chance that might be hampering the phone’s cooling capacity ?

That’s a thought. I’ll put Mrs BC’s iPhone on the charging pad next time, she has a newer phone (mine’s an X, hers is a Xs) with a different cover.

If you can, I’d try it without any charger initially.

But if a case is definitely required, I guess you’d want it as thin as possible.

Does the BMW charger have a magnet in it, to stop the phone flying about ?

I don’t know if there’s a magnet, probably is though as the phone doesn’t move on it much.

I’ll also try my iPhone on the charger without the case.

Yep, or as noted above the case.

My iPhone phone gets really hot using Waze anyway.

Laying it flat, in a case and on charge will only exaggerate this.

I remember reading that the case can help the phone to hold in a lot of heat, definitely try charging it without a case. How you will secure it is another matter!

Seen this on YouTube (mini clubman but still BMW and same issue). Haven't watched it yet but might be of use.

Well it’s taken this long for me to try a journey where I could try using the iPhone on the charging pad without its case. The result was that it took longer to stop working due to overheating. After an hour that was it, the phone turned itself off until I took it off of the charging pad and gave it time to cool down.

I’ll try again with Mrs BC’s newer iPhone.

I’d say that’s your problem. Waze is a massive battery suck, so the charger is working overtime to keep the phone charged. I’ve found my phone gets very hot running Waze, even with a cable power source. Running over CarPlay makes no difference, as all that’s doing is sending the screen to the car, the processing is still being done by the phone.

Interesting. I’ll try using mine for Waze and putting Mrs BC’s phone which won’t be running much on the charging pad.

What happens when you charge with a cable and run Waze?

I have an aftermarket wireless charger on my F36 and no issues at all with overheating, and that’s running Spotify on it almost constantly with the phone in a case.

I did manage to overheat an iPhone 6 using CarPlay though as it was pretty resource-hungry on an older phone - not in a BMW though.
