Quick question. I am abt 30 days into my 2023 M3 RWD. I have placed my iphone 12 pro on the charging pad and it barely charges at all - even when the phone is out of the case. Like 1% in 30 mins. Does this seem right? All my other cars w wireless charging were all pretty slow as well. Does it ever work any better than that? Thx.

Sometimes it doesn’t charge at all, sometimes it charges very well. It does heat up the phone a lot though. It’s not very consistent so I wouldn’t rely on it. If you really need a charge, I would just plug it in. Otherwise just treat it like a phone shelf and if it gains any charge it’s just an extra bonus.
Some phones work better than others. I recently compared my Android (Google Pixel 7) with a friend's Android (don't remember the model but different than mine). He would charge very slow and mine was good on the same charger, comparing the power that the battery receives using the "Ampere" app. Positioning of coils is important so sometimes your phone might not be a great fit. In his case it is probably a software difference. Removing the case might help too, but not always. It's possible that an OS update on your phone helps eventually, if that's the culprit.

The camera protrusions on the iPhone Pro and Pro Max models cause a gap between the charging pad and the phone causing more heat to be generated than charge to the phone's battery. The phone can also slide side-to-side, moving it from the optimal charging position.
I think the rate of recharging will depend a good deal on whether you have something active on the phone that uses much power. Actively navigating with something like Apple Maps or Google maps if you use that to second-guess the onboard Tesla nav puts my iPhone in a condition of not really gaining charge at all. It is slow, but much better than that, if no such power hog is active.
The wireless chargers don't work very well, and it's not just in the Model 3 or even Teslas. If you have an iPhone with MagSafe and really want to charge your phone wirelessly while driving, pick up something like this: Amazon.com

I find it does alright with a MagSafe case on an iP12, but if it slides slightly left or right you are toast. (This is in a 2023 Model 3)

iPhone can take only 7.5W via Qi, so it takes around 100 minutes to charge your phone.
Tesla M3 can provide up to 15W according to the manual (I have M3 2022):

My wild guess is that they have "Qi" and provide 5-15W, but iPhone (even the newest) can take only 5-7.5W
I'd say these are rather "supporters" than chargers. And it's OK)
