I would be happy just with the opportunity to easily, and affordably, replace the battery every two years so performance did not degrade. I went in to,an Apple store with my two year old 6s+ (No warranty) fully ready to pay the $79 thinking that this is just a cost of ownership. In the time it would have taken them to replace the battery and charge me the $79 they tested it and informed me that while the battery had degraded it had not degraded “enough” to warrant changing it. Now, to be fair, there was no charge for the battery test but I left the store with the same problem I went in with. Don’t you love it when the manufacturer thinks they know your needs better than you do?
I get it. They grudgingly will take your $79 when their software updates make a two year old phone obsolete but they really want that $800+ every two years. We know battery tech is hard. Apple’s competition tried to push this envelope and started fires. But Apple needs to accept the reality that if they are going to keep adding battery-intensive functionality year after year that they need to add BIGGER BATTERIES.
Imagine if they came out with an “iPhone Pro” with TWO of the same size batteries?! How insanely great would that be?! It would not be wafer thin fashionable but it would be useful.
