“While we expect battery capacity to decrease as batteries age, we expect processor performance to stay the same. However, users with older iPhones with lower-than-expected Geekbench 4 scores have reported that replacing the battery increases their score (as well as the performance of the phone),” John Poole writes for Geekbench. “What’s going on here? How many phones are experiencing decreased Geekbench 4 score?”

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

“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,” Poole writes. “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.”

MacDailyNews Take: Seems like the “fix” has consequences, intended or not.
