Other iPhone 15 pro battery life [Merged]

Why do so many people believe that myth?
The past few nodes have shown only transistor density is increasing by any appreciable amount, and even that is slowing.
I think this type of story is why there is an assumption that there would be major energy savings. I thought we might see a 20% increase in battery.

iPhone 15 Pro's A17 Bionic Chip Could Be 35% More Energy Efficient, Enabling Longer Battery Life
The A17 Bionic chip for next year's high-end models of the iPhone 15 lineup could be 35% more efficient compared to current iPhone processors...

Considering the 14 Pro Max already has pretty amazing battery, I don't see this as an issue.

Unfortunately, those articles are completely wrong because TSMC compares N3 with N5 v1.0, which was used in A14. The A15 and A16 already got the low hanging fruit.
And when they talk about 35%, it's the absolute best case scenario before TSMC revised down their numbers. In reality, the benefit of N3 over N4 is more like 10% power efficiency or 10% performance with 5% higher density.
Most people have experienced worse battery performance with the 14 Pro Max compared to 13 Pro Max and battery health has been terrible.
Consider yourself lucky. I regretted letting go of my 13 Pro Max when getting the 14 Pro Max. Battery life is horrible and let's not talk about the fastest battery degradation in the history of iPhone since iPhone 6 Plus. 13 Pro Max was amazing battery-wise, and the only reason I am going 15 Pro Max actually is that I hope the battery will last as much as the 13 Pro Max.
Someone said those numbers applied to the 14 Pro series are very "best case scenario" whereas on the 15 Pro it's probably going to be average/better than. Obviously there's no way of telling but I think the 15 Pro series battery life will be back to 13 PM levels (which were pretty good)
They have higher capacity batteries
So it’s actually
Bigger battery + more efficient processor = same battery life
Makes no sense
a17 pro is the first 3nm chip on an iphone. everyone was talking about how it would substantially increase battery life, but it remains the same. why?
Also weren’t the rumors reporting a bigger battery?
Because Apple prioritized power over efficiency, this is why this generation has such a big GPU improvement
Apple clocked the cpu so high and the gpu has ray tracing tech built in, so any power efficiency gains get cancelled out. Something has to give.
This is confusing way to say it as the parlance used when discussing chips is that efficiency means power efficiency. More clear to say that Apple prioritized performance.
I wonder that it was not mentioned more than "All day battery life" in the presentation. I am thinking take it at face value and then wait and see what happens. For some strange reason I think they did not say more and I think they might have done some things to improve battery life but decided to lower expectations so if it does better then pervious version then it will be a pleasant extra.
Their tech specs page gives it the same number of hours for video watching use cases as compared to 14 Pro. So that suggests it’ll be very similar.
Still, I’m hoping for improvements with them underreporting it.
Sure, the AP only takes a fraction of power budget so even the 3nm node change won’t be felt so much, I’d still hope for some improvement. Doubt Apple would clock the new node to edge out more performance at minimal power efficiency gains as suggested by some here. Seems like a strange choice for a smartphone.
people somehow associate smartphone CPU like how it works on desktop/laptops.
it doesn't correlate 100% where desktop CPU draws massive amount of watts, and second only to GPU.
theres not much to improve when it comes to SOC ... really
most of the battery drain is always attributed to either screen, and your 5g modem.
and theres no good solution for those.
if your OLED screen is still pulling massive amounts of battery, you won't see any gains even if they reduce it down to 1nm
