| This is so misleading as to be false. Batteries do not all degrade alike; not even close. There are huge differences in the rate of decay, and those are significantly impacted by the way the battery is used in the device (particularly maximum charging level, temperature, discharging level, power draw, charging rate) and the quality of the battery. Apple did NOT do a good job of degrading performance along with it; because if they had, they could have degraded performance before the battery became damaged. As a ballpark, I'd expect a life extension for the iphones in question by at least a factor 10 would be technically fairly simple and affordable; i.e. this isn't peanuts that apple left on the table here. A 10 year life expectancy is totally doable. So a battery as old as the decaying iPhone batteries need not have decayed significantly, as should be obvious considering that not all phones (let alone other Li-On battery devices!) degrade to this extent. The fact that iPhones did decay like this is almost entirely due to choices that Apple made (even if they made those choices without considering the consequences). Apple is pretty competent, so I'm a little skeptical they didn't know they were pushing the edge of what's reasonable, but sure, maybe it was incompetence rather than intentional penny-pinching or planned obsolescence. User choices can matter too, but given how locked down these devices are and how managed the environment and how technically nuanced the necessary user actions are to have an ameliorating effect it's unreasonable to assume users had any practical ability to avoid this outcome. |
