Yeah video calls can do it. Although the 14 Pro Max overall in my experience rarely gets warm even if I’m playing games or using the camera. But FaceTime after say 10 minutes gets it warm.

if you're not getting a temperature warning then it isn't overheating. calm down

No warning but I have 3rd degree burns on my hands, calm down

If you genuinely have third degree burns on your hands caused by said devices, you should be suing the phone manufacturers for damages instead of coming on Reddit.

I would but my hands got so burned that they fell off

Define "modern".

Google Nexus 4 worked best if you put it in a freezer if you wanted to run a benchmark. That was back in 2012.

The "Pocket Heat" app was available in 2010. Just running the CPU at 100% was enough to get the iPhone hot enough to warm your hands.

You need to stop being so sensitive about Apple products. calm down.

It's likely due to higher brightness of the screen of newer phones.

The 14 Pro Max heats up just looking at it...

I haven't needed to buy any portable hand warmers this year, the phone is hot even on idle.

Your phone definitely has a problem if it’s heating up when not doing much. Get it checked out by apple for sure then.

What case are you using? Some cases, like the Otterbox Defender, don’t allow phones to cool properly. Are you using Wi-Fi or cellular with your video calls (which are processor intensive which also causes heat) - cellular modems are power and processor hungry and can get your phone quite warm very quickly when doing video calls.

My 14PM almost never heats up unless I'm playing games on it for an elongated period of time. I would get the phone checked out.
