3nm needs a way less energy than 5nm.
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...www.macrumors.com
Most people have experienced worse battery performance with the 14 Pro Max compared to 13 Pro Max and battery health has been terrible.Considering the 14 Pro Max already has pretty amazing battery, I don't see this as an issue.
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.Considering the 14 Pro Max already has pretty amazing battery, I don't see this as an issue.
They have higher capacity batteriesSmaller phone = smaller battery
Also weren’t the rumors reporting a bigger battery?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?
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.Because Apple prioritized power over efficiency, this is why this generation has such a big GPU improvement
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.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.
