User level: Level 6 (10,614 points)When I’m holding my iPhone 16 Pro and it’s plugged into a charger, it often stops charging because the iPhone is too hot. Are there ways I can hold it that will minimize this? A related question: Where are the temperature sensors? Thanks for any information.

iPhones have always paused at 80% when fast charged to allow the battery to cool down, but they didn’t display a message; they just paused until the phone's temperature stabilized.
Users have sometimes asked in ASC why it has “stopped charging at 80%,” and this is the answer; that it has to cool down, and will resume after a pause.
The way to minimize it is to not fast charge.
With iOS 16.5 and later Apple has added a message SAYING why it has paused. But if you had never noticed that it paused at 80%, then this sounds like the update broke something. It's normal, just more information about why it paused.

I believe I’ve seen my phone stop charging at other than 80% with a message about temperature, but I’ll have to wait to see it again to confirm that.

My iPhone just stopped charging at 87%. The message says, “Charging On Hold”
“Charging will resume when iPhone returns to normal temperature.”
This is definitely NOT the 80% fast charging situation.
