iPhone 6s notevolmente più lento (geekbench)

Sembrerebbe essere un cambiamento intenzionale nel modo in cui i telefoni funzionano con l'invecchiamento della batteria, per prevenire l'arresto anticipato in cambio di prestazioni più lente.

Performance and Battery Age So what’s going on here?

First, it appears the problem is widespread, and will only get worse as phones (and their batteries) continue to age.

Second, the problem is due, in part, to a change in iOS. The difference between 10.2.0 and 10.2.1 is too abrupt to be just a function of battery condition. I believe (as do others) that Apple introduced a change to limit performance when battery condition decreases past a certain point. Why did Apple do this? kadupse on Reddit offers the following explanation:

"Many iPhone 6s devices were shutting down unexpectedly, even after the battery replacement program (Which many people weren’t entitled to use). Because degraded batteries last much less and end up with a lower voltage Apple’s solution was to scale down CPU performance, it doesn’t solve anything and is a bad experience… but it’s better than having your device shutdown at 40% when you need it the most."

Apple acknowledged the sudden shutdown issue that affected the iPhone 6 and iPhone 6s earlier this year. However, does the same issue affect the iPhone 7? Apple appears to have added a similar change to iOS 11.2.0 for the iPhone 7.

If the performance drop is due to the “sudden shutdown” fix, users will experience reduced performance without notification. Users expect either full performance, or reduced performance with a notification that their phone is in low-power mode. This fix creates a third, unexpected state. While this state is created to mask a deficiency in battery power, users may believe that the slow down is due to CPU performance, instead of battery performance, which is triggering an Apple introduced CPU slow-down. This fix will also cause users to think, “my phone is slow so I should replace it” not, “my phone is slow so I should replace its battery”. This will likely feed into the “planned obsolecense” narritive.
