I guess they made the chip and RAM a lot bigger but didn't make the battery much bigger. The battery life is still decent (4-8 hours depending on work load) but not amazing.

#32Why is weight even a concern? Thinness I get because that makes a real difference in your pocket, but what's the point of reducing the weight a tiny bit?
So now they have introduced the titanium frame as a solution to their self-inflicted problem, which still isn't as light as the aluminum non-pro iPhones.

The problem is that the temperature you feel on your hand is not necessarily the temperature the chip is operating under. If your hand is warm that, ironically, means the heat is dissipating effectively. If it's not dissipating, then your hand will remain cool because all the heat is still on the chip. So unless Apple gives you a way to read the chip's own temperature sensor data, what you feel holding it isn't that…
Normies care about the fact that it's uncomfortably warm to hold, not whether the CPU is hot or not.

Mostly because they insisted on making the Pro models with stainless steel instead of aluminum, which made them way heavier for no reason. The 34 gram difference between the iPhone 14 and 14 pro is very noticable in the hand. So now they have introduced the titanium frame as a solution to their self-inflicted problem, which still isn't as light as the aluminum non-pro iPhones.
I suppose being design sensitive folks, as many Apple customers are, you could argue that plastic looks cheap. But then, most iPhones these day have a case that completely hides those stainless steel/aluminum/titanium/glass parts anyway...

If you've ever tried to play a game on the iPhone/doing something else CPU/GPU heavy while outside in the sun on a hot day, you'll know what I mean, the performance is much worse.

#37I wonder if this is related to the use of Titanium and the poor thermal conductivity of Titanium (17 W/m-K) vs. Aluminum (210 W/m-K).
Aluminum dissipates heat more than 10x better than titanium.

EDIT: I no longer think it's thermal conductivity due to the change in metals. See below.

The previous generation of iPhone Pros used stainless steel instead of Titanium.

For this review, we used two iPhone 15 Pro Max units, obtained from different retailers, and neither of those became unbearably hot even after an hour of GPU stress testing.

> GSMArena bought two iPhone 15 Pro Max from different retailers to test the overheating issue and they were unable to replicate it. Did anyone manage to "replicate" the explosion of a Galaxy Note 7 under controlled usage? Assuming no one did, what conclusion wiuld we draw from s failure to replicate on n=2?
It's just another data point.
IMO, it sounds like it's a real issue, but not one that affects the majority of users.
