    When I use the wireless charging feature in my 2018 Honda Accord, my iPhone X gets quite warm; much more so than in my Mophie bedside charger.


    AFAIK, this is causing no damage, but that is just a guess. Is there any reason for concern or am I worrying over nothing?

    If you place your wrist on the display and it feels hot while charging, it is too hot. Maybe not to damage it, but certainly enough to put accelerated wear on the battery

    Your phone should not get “hot” when charging. I have used the Morphie charger for over a year and the most is I can say it is get “slightly” warm. Never hot.

    Energy not used by Inductance charging manifests as heat, it's a drawback to the technology. More heat from one charger to another is often due to higher output. Perhaps your car's charger is higher output than your Mophie?

    I have no idea what Honda's output is, but I'll call Honda and see what they have to say.

    And, many thanks for all who chimed in!

    Spoke with a Honda support tech. He advised that a phone getting "warm" is not unusual, but as yet they have not received reports of the phone getting "hot" (mine will be the first). He suggested that I also take the problem to my dealer/service tech and document such on my "Service/Repair" order and ask that the condition be checked. That way, there will always be a detailed record of the issue. He further opined that these are also good to have in case of recalls, etc.

    FWIW 1, the Honda tech spent about 10 minutes researching the problem and seemed genuinely interested in helping.
    FWIW 2, I wonder if the chargers for Toyota & Honda (and others?) are made by the same supplier...

    Perhaps of interest...

    I just discovered (by reading the manual), that the Charger has an on/off switch. While it is not readily noticeable, it is still apparent where at least some of the blame lies...
