I agree, but like I said, it wasn’t the point.
I’ve seen people who were talking about replacing an iPhone 15’s battery something like 7 or 8 months in with 87-92%. Sorry, but I’ll never not find that ridiculous.
The thing runs iOS 17, it has like-new battery life, what do you need a new battery for? At some point it feels like they’re replacing them just to see 100% on settings.
We all like that, sure, but it’s pointless.
Please don’t mix up and compare different things …
iPhones 15 have a case made of titanium.
compared with aluminium a case made of titanium has only 50% of the ability to uptake and transfer heat to the outside of the case. design a case of a high-tech smartphone using Titanium instead of Aluminium is therefore an amateurs fault.
So it was clear that the iPhones 15 often got overheated when used intensely and often enough even in situations of normal use or higher environmental temperatures.
apple seems to have reacted purely on the symptoms by automatically lowering performance if the IP 15 got too hot.
They could not exchange the titanium case case by the better aluminium case…
But they learned by the hard way that they should never ever use titanium cases.
Now you know perhaps why they stepped back to aluminium-cases ?
But overheated smartphones means also overheated batteries.
And we all know that heat is very bad for reliability and function of batteries.
So, you can say the catastrophically bad reliability of the batteries of the iP 15 was at most part NOT about the IOS, it was because the „engineers“ ignored facts that you learn even in school at the age of 15 or 16 years in lessons about chemical basic knowledge…
I did write about this already in threads about the overheating of the iP 15… at the time people started to critisize the bad battery performance of the iPhone 15 at that time…
but most people didn’t understand… which is very astonishing because these facts are not a secret science this is well known since about 100 years…
So - if people talk about SPECIFIC battery problems of iPhones they should exclude the iPhones with a titanium case and talk only about iPhones that are made using Aluminium cases . Because iphones build with Aluminium cases (like the iPhone 14 line) did NOT have the same problems with overheating although they ran as well on the new IOS Versions…
