There is no advantage to running a phone at high power for prolonged periods of time. Reducing the performance to conserve power is usually a better choice.
Like gaming?
I doubt that having higher heat dissipation is detrimental. What would be the implication of the phone having better heat dissipation? Aren't heat dissipation and SoC consumption orthogonal?

Yes, running at a higher power would allow better looking gaming or higher FPS, but at the cost of massively reduced battery time. Probably the 14W power figures aren't intended to be sustained for long as it would result in very poor battery life. However allowing the 14W for shorter tasks can be beneficial while not having a big impact on battery life.
Usually you don't want the heat to conduct too well to the device frame because it can make the device too hot to the touch. And since the iPhone can only cool itself through the device frame...
I prefer to play with better quality for longer, even if it means having to charge the phone more often.
That could be an issue, because new iPhones get hotter than previous generation.
Apple when announcing M2
“Unlike others in the industry, who significantly increase power to gain performance, our approach is different. We continue to have a relentless focus on power efficient performance. In other words, maximising performance while minimising power consumption.”

Intel and AMD increases performance at a cost of efficiency every year and people criticise them. When Apple dramatically increases wattage to gain a small 10% increase in ST performance with A16 and A17, Apple people loves to say it’s not a problem. ‘Nothing to see here, folks.”
It’s not a small increase. It’s approximately 400 geekbench points. Pretty much the biggest increase in the history of Apple Silicon.
We discussed how it’s more efficient at the same performance level as the A16 previously.
But while we’re playing that game…
When Apple has a Soc focused on portable efficiency: “no one cares about efficiency”.
After Apple creates a new Soc that scales and obviously has to use more power: “EFFICIENCY!!!!!”
To be honest, when a company controls both os and hardware. It is not that hard to manipulate Geekbench scores. It is like a player also the referee.
The iPhone 14 Pro is hotter than the iPhone 15 Pro Max. The 15 Pro is hottest of all. The 15 Pro Max has a narrower range that is hotter , which is suggestive that it isn't spreading the heat around as well (e.g., all the 'green' on the left hand side of its image. )
The plain 'pro' is smaller so that doing a bad job of distribution just collapses deeper.
Apple redid the internal aluminum in the 15 models to lower the weight also. Decent chance that was a 'trade off' in design in terms of thermal distribution. ( lighter vs worse distribution ).
Same folks who brought you 'run too hot' laptops so not particularly surprising.
The Apple silicon group instantly became the words best CPU design team right with the release of M1 because of its performance per watt achievement. No one has slammed Apple Silicon for its laser focus on performance per watt.
lol. Ok buddy. So Intel and Amd get credit for Geekbench, but Apple is cheating?
Could you elaborate on this cheating? How does it work?
The problem is they also opened up a use case mode where getting power delivery from an external display. That whole run it like a console gaming system set up is likely a path to some screwed up phones over time.
The fact the self regulation subsystem doesn't stop things before they get 'horrible high' is a dubious design choice ( if not a defect. ) . If developing this for 'bursty' activity then it should shut down when timeline for a burst should be over. 15-30 minutes is not a 'burst'.
Something is majorly wrong with all of the charts you're relying on. How can that be an accurate measurement of iPhone performance running "Android's Highest Preset"?
And A17 power efficiency is STILL far ahead of the competition even with a power increase. Sometimes power consumption has to be increased, that doesn't negate a push towards overall efficiency.
That has been AMD’s and Intel’s excuse for years and we gave them crap for it. Now, Apple does it and we can’t give them a pass.

Need more tests but...
15 Pro Max lasts longer than 14 Pro Max and 13 Pro Max (the former king).

I haven't played the game, so I can only make guesses. I would imagine that the settings are different between iOS and Android, and that they are using the best possible settings for the game on Android to play on the iPhone.
In the Chinese version of the video they make no reference to Android, although the graphics look identical.
People weren’t giving them crap for increasing power. They were giving them crap for increasing power as their only means of increasing performance.
Luckily we know from the tests, that the A17 is more efficient at the same performance level than the A16, while scaling up to higher performance levels.
If your efficiency is about 3x better then the other guys', your headroom simply is much higher than if you're constantly on the limit (like Intel/AMD in your analogy).
Just not the same thing.
