Thanks for this .
Maybe I’m just being unreasonable but just seems like battery health is dropping too quickly .
And I’m comparing to my previous iPhones - I have used iPhones for about last 8 years and none of them previously wasn’t at even 80% after 2-3 year use .
What's the saying in investing? Past performance is not indicative of future results.
There's really no way of knowing. Apple has this extremely generic nominal rating of 500 charge-discharge cycles before an "expected" battery health of 80%. For every single iPhone model since the iPhone 5, no matter how big or small. Seems too perfect, doesn't it? In the end that's just an expectation and the standard for which they judge battery warranty (or AppleCare) claims simply for premature loss of capacity. But it's just shoehorning many conditions into something that's easy enough to understand and implement, such as (I've used this analogy before) Michelin offering a treadwear warranty. There's no way that they can really know that every set is going to last exactly 60k miles. But they have a good idea what it's going to be like on average, and they hope that most do better so they don't have to pay out claims.
If it really bothers you, there is the option to pay for a new battery. Or many don't wish to pay and get a USB power pack to supplement an internal battery.
