They put a 19 pro inside it then cover it with Titanium, could it even run full speed for 5 minutes? Would it hurt hand?

Apple said Titanium is 20x hotter than aluminium that they put on pro, how can heat even release in such a thin body, titanium, and no any special release heat setup?
 
Aluminum is about 10 times more efficient at conducting heat than titanium, so makes sense they went back to it with the Pro.

For the Air, it seems like majority of the body is the battery right? And processing components / chips are up top in the housing/plateau. Hopefully this helps. Although just looking it up, glass is nearly 20 times worse than titanium. So it's no wonder you would feel a lot of these glass backed phones heat up under heavy use.

Much of the heat will be felt though the frame edges.

Titanium is a poor heat conductor but still better than glass.

If you’re intending to use this phone for any kind of heavy work (e.g. AI transcription, gaming) it’ll throttle quickly.
 
Did I somehow luck out with my 15 Pro and 16 Pro? Both titanium and never once has it even remotely got warm, let alone hot - in intensive, constant use.

🤷🏼‍♂️

17 pro is with aluminium for some reason, very likely a19 pro is just so hot

since this is a re-design...aluminium and vapour chamber are not just for the a19 pro that could be hot or not but also for the upcoming a20/a21/a23...so this is NOT just for the a19 pro
In the Air probably the cores max clock speed are locked at lower hz also

If you watch the Air marketing video, you’ll see that the titanium frame has a gap where the camera plateau is located, which also houses the A19 Pro. So it’s probably not covered by titanium at all. In fact, it’s not clear if maybe it isn’t just the edge that is titanium, and maybe the back plate below the glass is aluminum. The glass covering the camera plateau has worse thermal conductivity than titanium though – it’s not clear what the intended heat dissipation pathway is. Maybe the camera plateau will become the hottest part.
 
The Air battery is in a metal enclosure and the back of the Air is made of glass. Glass is a terrible conductor of heat. It should remain fairly cool. I'd also assume the A19 Pro chip is being used to efficiently throttle CPU and GPU speeds to conserve battery.

The Pro has an aluminum body and vapor chamber so that it can dissipate heat through the body of the phone while running at full speed. I would expect the Pro to get much hotter than the Air.

Likely done to save on weight. The aluminum 17 Pro is heavier than the titanium 16 Pro. The 17 Pro would have been even heavier if they had stuck with titanium.

You mean the heat would trap inside the Air, and that just mean you may feel by hand a lot but the heat trap inside would force it to slow down or even shut down.

A19 Pro gets hot, A19 Pro throttles down to reduce heat.
Air battery gets hot, heat is dissipated to the steal battery case.

Ambient heat from A19 Pro and battery case leave the phone through the titanium rails mainly. Titanium is more of an insulator than aluminum, so I'd expect the Air to throttle quite a bit. But very similar to the 15 and 16 Pros.
