Thanks for the speculations, I don't think this discussion is going anywhere, I rest my case. You have a right to keep stating your opinions without supporting them with facts.Where does that say the iPhone 6 battery is defective by design?
As for 1. The batteries are not capable of powering the phones. That's why the throttling. That's why the lawsuits. That why this article. That's why governments are investigating apple. That's why the $29 battery replacement. These definitions of C are another poster's attempt to explain why everything above is going on. I believe the poster is right, but that is irrelevant to the issues at the start of this paragraph. You're attempting it turn it into an XY problem https://en.wikipedia.org/wiki/XY_problem and then saying since I don't want to prove Y, X must be false.
As for 2. Show me where I said Apple batteries have a high internal resistance at BOL. You are once again pretending I said something I did not. As for EOL, all batteries have a high internal resistance at EOL; that's true but irrelevant to this conversation because nobody is complaining that batteries reach EOL. Are you going to ask me to prove 1 + 1 = 2 next?
I agree about two different claims in the statement that you specified.No, “iPhone is defective by design due to its battery” and “the iPhone battery is defective by design” are different claims. Specifically, the claim here is that the battery is a poor fit for the rest of the specs. Put in lesser CPU/GPU/etc., or beefier battery.
(I don’t know if I agree with that, but to give it some merit, iPhone 5s and older never seemed to have these problems at comparable scale.)
The original quote was 'Apple chose the wrong battery for their iPhones and every iPhone since the 6 is defective by design'. I asked the poster to prove the the wrong battery choice as a defective design decision. The poster is doesn't seem to want to engage in a deeper discussion to add weight to his claims, which for the most part are empty claims.
5s and older devices might not have had the same issue or might have had unreported issues related to power management. The direct correlation that iPhone 6 and above are throttled when the battery deteriorates to defective design is preposterous.
