My iPhone 14 Pro Max started overheating while in use
Hello,
My iPhone started overheating while in use. It is too hot that my palm got sweaty.
is there anyone who is experiencing the same?

Wow, thank you Lawrence! I absolutely appreciate your level of technical information you supplied with regard to this thread. Bring it on! I want to hear anything you have to say about the iPhone 14 promax.
OK, how’s this for a start: Do not close "background" apps | Communities
Did you close all your open windows? I went to the iphone pro max gestures in the usermanual and learned you must swipe straight up to the center of the iphone from the middle of the lower margin in order to see how many windows are open simultaneously. if you leave many on, then your processor is working overtime. You also sometimes have to close windows in a browser you are using (like edge) which are numbered for your convenience; and these remain "open" even after you have closed the others with the above mentioned swipe technique.

Actually, that is not true. I currently have 120 open apps on that screen. That is a list of apps that you have used in the past, it is not a list of apps that are running.
Your observation about Safari is valid, however.
If the phone overheats it will shut down and display a message saying it has to cool down. If this does not happen the phone is within its safe operating range. The phone will get warm with some usage patterns. It’s called the Second Law of Thermodynamics. Anything that creates or uses energy does so with some loss. That lost energy is expressed as heat. So when you charge the phone it generates heat in the power source, heat in the charger circuit in the phone, and heat as the energy goes into the battery. The faster the charging, the more heat is generated. Likewise when you discharge the battery; not all of the energy from the battery gets to the circuits that use it. Some of it becomes heat.
If you use the cellular network for voice or data, converting energy to radio frequency signals is very wasteful; only about 30% of the energy that goes into the network components comes out as radio signals, the other 70% becomes heat. And signal strength matters; a 1 bar signal requires that the phone boost its transmitter power to maintain a connection, and it isn’t linear. 1 bar uses 10 times as much energy as 4 bars. You didn’t mention your phone model, but an iPhone 12 or newer (including SE 3rd edition) with a 5G signal uses about twice as much energy as an LTE signal, and 5G towers are still not as densely distributed as LTE, so the signal is likely to be weaker, compounding the problem.
