With Optimized Battery Charging all iPhones can stop charging when they seem fit. No additional hardware required.
But optimized battery charging is not this feature which keeps the iPhone at 80% even as it’s being used. If it was just software apple would roll it out to past models.
The MacBook I installed it on is an M1 MacBook Air.
I have a work 16" MacBook Pro but I haven't installed it on that
Time has shown us many times that Apple really likes to make some software things current-model-exclusives, so, no, Apple wouldn’t just do it because they can, they chose not to with many things in their history so that’s not an argument.
Also, yes Optmized Battery Charging isn’t the same feature, but it basically performs a very similar action, to stop the iPhone from charging last 80% even if it’s plugged in or placed on a charger. So, very obviously, there is absolutely no extra hardware required. Apple just chose not to make a user accessible version of this available to olde devices because they want to. Not because they can’t.
Maybe apple does like to keep features exclusive but that doesn’t mean there isn’t a specific chip for this.
Personally I doubt it, they don’t need to reinvent hardware solutions for something that is easily possible with software, that doesn’t make sense from a RnD and profits perspective to me.
Just like with the Watch S9‘s hand gestures that are practically the same as with previous versions of watchOS in accessibility settings, they just chose to make a different version of the same basic feature exclusive for certain models. It’s both literally nothing new and both technically require no additional hardware.
Albeit with the Watch maybe they tweaked some aspects of the hardware to make it more reliable because it doesn’t work that great on my S7, and yes with the iPhone they could have added some hardware protections for certain situations were somehow the charge wouldn’t be blocked previously, but that doesn’t justify this black and white approach where it’s in no way accessible on other models.

I got what you are suggesting but a feeling that it is so, is not proof. It’s a good question but unless someone comes forward with additional information this is speculation and rumors. Comes with the territory.
To anyone saying my claim of frequently turning on and off your device hurt them badly is false, if you ever wonder why the circuit breaker inside your home is what it is, that is because closing a circuit with large current can generate arcs (among other nasty effects), since air can be a conductor of electricity when being penetrated. Modern circuit breakers for home use and for substation use are designed in a way to minimise the impact of heat and arc caused by connecting and disconnecting power with large current.
For consumer electronics, there is no shortage of stories people charging their other electronics and end up lighting the entire house on fire caused by poorly manufactured charging bricks, and people have learned to pick reputable chargers so as to not be caught by life-threatening surprises if charger goes bad. Old computers like Commodore 64 had such bad power brick users today need a protection device or modern power brick in between to not fry their admittedly very rare machines.
Your iPhone has protection circuit to protect your processor, memory and other more fragile and sensitive electronics from being fried by nasty things such as surge current, and I am fairly confident engineering in Apple has designed the circuit with enough margin so that under day to day use your device would very unlikely to be destroyed. That does not eliminate the fact that surge of power goes through all components in an instant when you turn on your device. It’s just that all of those protections in place will not let disaster become regular occurrence.

Thanks for the system haptics and aeroplane mode when connected to wifi network "x" shortcuts. Those were useful.
Doubt it. My iPhone 14 Pro (aka iPhone 15 with 3 cameras) should have it then. This is very typical behavior of Apple to slowly and subtly reduce the viability of older models, when in our phones can be updated beyond what they are - Apple chooses not to.
True. But can’t say yes and can’t say no. If this isn’t a hardware function it seems like a no brainer to at least have it on the previous high-end model.
Charged my iPhone 15PM last night and now, at 8:50 PM it at 68% how does a person manage to drain the battery completely in one day. It’s been on all day with everything they recommend turning off on.
