    my iPhone got pretty hot the last few times I quick charged or after a face time call with people. I thought since it’s water resistant I could run it under water to bring the temperature down. I did it once and thought it’s an awesome quick way to cool it but I am no engineer nor physicist to know if I’m damaging the components.

    That's what I consider a good use for a zip-lock bag --- I don't trust the "water-resistance" on any device.

    But then, I wouldn't "water-cool" my iPhone, even if it was too hot to hold. Standby, or off, and 10 minutes in that condition would cool it off naturally without having to risk that water resistance, and hope it holds :cool:

    I went in the ocean to dunk my iphone. Does that count. I was the one that was overheating though.

    Threw my iPhone X into the Arctic Ocean after it heated up during Fortnite. Even though I can’t find it, I can be rest assured it’s running cooler now.

    Just kidding :p

    Or, you could simply leave your phone sit for while to cool down without having to expose it to water every time it gets ‘Hot.’ I personally would risk rinsing the phone under water in your situation, regardless of the water resistance rating.

    Rapidly heating and then cooling electronic components and plastic casings is an excellent idea. It keeps them soft, elastic and supple. If you do it well, you'll be able to get a gentle curve in your phone so it sits flush against the new iPads.

    Yea good point. Wonder if the OP has ever poured boiling hot water onto a frozen windscreen?

    No better way to ruin a water resistant phone is to cool it rapidly under cold water so it get sucked into the guts and kills it. We need a video:p

    I normally put my phone in a bag of ice cubes when it gets hot so running it under water should be fine!

    I swear I can't tell if you are serious or not, but I will say just let your phone do what it is supposed to do, heat is a byproduct of use. It will be fine. As others have mentioned rapid temp changes are never good for dissimilar metals, plastics, silicones etc.

    Where I live (in the desert) the temperature reaches over 108° to 113° every day during the summer. Without AC (which I don't use) there's no way to use an iPhone. It's too hot even when off.
    The solution to this is to wrap a small rectangular Blue Ice frozen gel pack with a rag and rubber band it to the back of the iPhone. Use the formed plastic ones, not the flexible bags.

    The older style iPhones (8 and below) that have the larger bezels work best for this because the rubber band can wrap around the bezel and not the screen.

    When its 113° out (or higher) and I'm using the iPhone heavily (with the blue ice pack strapped on) the battery/phone temperature stays at about 78°F. The phone never gets hot or too cold. It's important to wrap the blue ice pack with a rag to insulate it a bit from direct contact with the back of the phone. Otherwise it'll chill it down way too far and likely be bad for the device and battery.
