Iphone charging, overheating the phone, possible cause?

[Alan]

So does anyone know if the coil in the ct is to high or to low.

Tesla actually sells a Wireless Charging Platform, presumably one of their in-vehicle chargers stuffed into a desktop case:

Which purportedly looks like this internally:

With that many coils it's hard to miss! The Cybertruck charge pad may be different internally, but I'm not willing to take mine apart lol

The Model Y charger looks very different internally:

But this is a "V3" revision, and the Cybertruck is "V5".

Coil alignment is where inefficiencies are created. The phone being an iPhone has nothing to do with it... It's all about coil alignment. This has to do with the charging pad, not the phone as there is no standard placement for coils defined by the Qi2 standard.

No, iPhones have coil designs that are purposefully more sensitive to placement on wireless chargers. The Qi standard allows a range of coil designs. That's why they work best with MagSafe chargers. And having the camera poking out of the back doesn't help.

It's not that I hate Apple, it's that I don't like the way they try to force their customers to have an all Apple ecosystem. They are the definition of a walled garden.

my iPhone 14 Pro charged perfectly on my 2021 Model S (which has an air vent directly above the charging pad constantly blowing air for phone cooling). On the Cybertruck, it’s a hot, non-charging, mess. No cooling vent anywhere that I’ve found. Feels like Tesla created a problem when they already had a solution here.

Question: When people say their phones are overheating, do they mean the phones just get pretty warm, or is a message popping up on the screen that says the phone has overheated and either stops charging, shuts down, or some other action?

As stated, the problem with wireless charging is alignment. The way I understand it, Apple saw this issue and solved it by using magnets to hold phone and charger in perfect alignment. I do not know about the coils Apple uses, and if they used special coils to make non-Apple chargers work poorly. I don't think that is true, but if it is, it would not surprise me.

I don't know why people talk of Apple's walled garden so negatively. Come inside, it's freaking awesome in here!

Tesla does not use that array in the vehicles but they should.

Your messages are once again uninformed. Their coils are no different, either an understanding how inductive coils function physically or a teardown comparing the coils demonstrate this.
You continue to just make things up without providing any information or evidence and for some reason feel the need to validate your feelings instead of acknowledging facts.
They aren't forcing you to use a MagSafe charger, you can use a Qi2 at the same speeds.

How is Apple forcing users to do anything?
Apple did not start the camera bump nor is it even close the only premium phone to feature it.

Here's real life proof your claim is false and you have zero idea what you are arguing about.


You've provided zero substance to this thread and instead have filled it with your feeling and opinions while presenting those as fact.

Unless you can comeback with some data or evidence proving the FCC filings to be false, the datasheets incorrect, and the real-world tests to be fabricated, there's zero use in anything you post in this thread. You're ignoring facts because you want to be correct, not because you are correct.

Some phones are getting warnings and stop charging due to thermal limits, it happens on both Apple and Android phones. Some phones are getting just warmer than they should under ideal wireless charging such as the iPhone 12 mini.
They're not special coils, induction coils all work the same when rated for the same specs.

I had an idea for a product to solve this issue.
Was hoping it already existed.
I searched the internet for it with no luck. May not be technically possible.
A MagSafe to Qi adapter.
I envisioned a hockey puck that had a Qi receiver on one side and MagSafe on the other.
At least thick enough to overcome the lense protrusion.
Any thoughts?

I'm still waiting to see if anyone knows of such a magical device or if it is theoretically not possible.

or I might custom cut out this: Amazon.com: LUCKEASY for Tesla Cybertruck 2023 2024 Wireless Charger Mat Car Center Console Auto Interior Anti-Slip Protector Pad Cybertruck Auto Interior Accessories Black : Automotive to see if I can get a "perfect" line up and less heat. Might require more experimentation than I have in patience. LOL.

It's entirely possible, it would create more heat and inefficiencies due to now having another set of coils, so hopefully whoever makes them choses to use aluminum for the frame, adds thermal contact points for the housing or potentially adds a shim heatsink with a some venting.

The issue is I think the coil is not in the right spot to charge most people’s phones.

If you know exactly where the coil is, you could put an adhesive MagSafe ring on the CT’s charging pad and get it lined up perfectly every time. Or you could simply prop up the phone higher if for example the coil is higher than it should be.

What we would need is someone to take apart the Cybertruck’s charger and see where the coil is.

Another way to figure it out would be to experiment with the phone in different locations and measure charging rates with an app like Ampere. This is probably best done with an Android phone because iOS charging info seems a bit more locked down.

If Tesla did in fact put a bunch of coils in there to allow for arbitrary placement of the phone I’m afraid they made a really bad mistake. Remember Apple’s AirPower blunder? Apple tried to make a charging pad like that and ultimately couldn’t pull it off. It was cancelled. If a company with Apple’s resources cant pull it off Tesla’s efforts are doomed to fail too.

I was going to create this myself, but during my testing phase, I used an official MagSafe charger from Apple plugged into the usb-c port and it also overheated same as the Tesla charger.... so I am wondering if it really has more to do with the ambient temperature.

The coils vary in size and number. Some are more sensitive to positioning. That's the primary reason why some phones charge better than others. The video you embedded is not proof of anything.

That's easy, the Cybrertruck is correct, Magsafe iPhones moved theirs.

You first. Or maybe email Munro?

I’ve never had a MagSafe get anywhere near as hot as on the CT charge pad.

 

[M0unt41nm4n]

Interestingly, I have an iPhone 15 Pro Max… the big one. When I put it right side up in the CT, it gets wicked hot and doesn’t charge… I.e it says it’s charging but it loses the charge rapidly. When I turn it upside down, it charges and doesn’t get nearly as hot. It gets relatively warm, but not like when it’s right side up.
