PSA do NOT leave key fob on the phone charging pad!

[151614]

Dont leave the car fob on or close to the phone charging pad in your CX5 of any other car!

The electromagnetic fields from the pad can damage the fob or make it not operate properly.

I have never done it but mate did in his Toyota Prado and was just lucky it wasn’t fried.

The pad doesn't activate unless it detects a capable device. If you put something like the key on it, you'll see a red light vs the normal white or green light.

And it has an on/off switch. Keep it off when you’re not using it.

I must have missed that when I got to section 5:38-42 of the manual. Probably skipped over that bit.

I have now turned it off. Even better, it stayed off when the car was turned off and then restarted. Hopefully it stays off!

My manual only says not to put the car key fob near it when its being used to charge a phone. Mentions not putting other devices and cards near it otherwise.

I don't use mine at all. I find it superheats the phone and the charging is less than ideal. I should turn it off.

I don’t know if this applies to all wireless chargers, because I haven’t used them… but the Mazda owners manual says that before using the Wireless Charger, make sure to back up the data stored on the phone. The data on the phone could be deleted.

I think my 2023 CX5 charger pad is the worst possible charger pad....I have never gotten to work properly on my Iphone14 pro...seems the phone just will not align properly on the pad..i can wiggle it around and the green light will be on for a few seconds then the slightest bump and off it goes....

The performance from the pad on our 2022 Signature was quirky as well. Charging on my iPhone 15PM varied depending the case and how hot the phone got. I'm sure that the presence of that camera bump is not optimal either as having a space between the Mag-safe ring and the pad surface has to degrade efficiency.

I have a pad in both my CX-5 and Audi A3, and the wife's CX-30 has one too. All are pretty useless unless you want to heat up your phone to potentially harmful levels, especially if using wireless AA or Carplay. This is with my Samsung or the wife's iPhone.

I don't pin this on the pads themselves particularly, but the combo of wireless charging and the phones using their radios and processors heavily when using wireless AA or CP just overheats the hell out of them. I believe some fancier cars actually have a cooling fan on their charging pads to help alleviate the heating problem.

On my 2025 CX-5 I tried to use the wireless charging pad… my iPhone didn’t charge but got pretty hot. I turned the pad off.

Def. one of my negatives for the interior. The slope of the pad makes it impossible to keep my phone in the same position to charge. Poor design.

This is a big issue with wireless charging in general from my experience. I don't have a wireless pad in mine but when I have used them in hotels which have them in the room, the phone does heat up. Considering the phone gets hot when using wireless AA anyway, this makes things worse. It seems to me there is a lot of development still needed for battery based items. Many things have not been worked out sufficently. This is a big reason I have no interest in an EV. I think the tech has a ways to go.
