Other key upgrades tipped for the iPhone 15 Pro and iPhone 15 Pro Max include a stronger and lighter titanium design, a new periscope zoom and even longer battery life (thanks to the same 3nm chip). This technology will apparently underpin the M3 series of tablet/computer chips too, which gives us high hopes for the processing abilities of upcoming iPads, Macs and MacBooks. This will likely feed into the “planned obsolescence” narrative.Such a performance boost looks unbelievable but could be possible since Apple's tipped to be moving to a 3nm process for the A17 chips, which should offer more power and power efficiency than existing 4nm chips. 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”. 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 creates a third, unexpected state. Users expect either full performance, or reduced performance with a notification that their phone is in low-power mode. If the performance drop is due to the “sudden shutdown” fix, users will experience reduced performance without notification. 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. 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.Īpple acknowledged the sudden shutdown issue that affected the iPhone 6 and iPhone 6s earlier this year. Many iPhone 6s devices were shutting down unexpectedly, even after the battery replacement program (Which many people weren’t entitled to use). Why did Apple do this? kadupse on Reddit offers the following explanation: I believe (as do others) that Apple introduced a change to limit performance when battery condition decreases past a certain point. The difference between 10.2.0 and 10.2.1 is too abrupt to be just a function of battery condition. Second, the problem is due, in part, to a change in iOS. See, for example, the difference between the distribution of iPhone 6s scores between 10.2.1 and 11.2.0. Performance and Battery Ageįirst, it appears the problem is widespread, and will only get worse as phones (and their batteries) continue to age. However, the distribution changes with iOS 11.2.0 and starts to look like the iPhone 6s distribution from 10.2.1. The distribution of iPhone 7 scores under iOS 10.2.0, iOS 10.2.1, and iOS 11.1.2 appears identical. Under iOS 11.2.0 the effect is even more pronounced. However, the distribution of iPhone 6s scores for iOS 10.2.1 appears multimodal, with one large peak around the average and several smaller peaks around lower scores. The distribution of iPhone 6s scores for iOS 10.2.0 appears unimodal with a peak around the average score. Scores obtained in low-power mode are not included in the distribution. To answer these questions I’ve plotted the kernel density of Geekbench 4 single-core scores for the iPhone 6s and the iPhone 7 running different versions of iOS. What’s going on here? How many phones are experiencing decreased Geekbench 4 score? 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). While we expect battery capacity to decrease as batteries age, we expect processor performance to stay the same. A Reddit post from last week has sparked a discussion regarding iPhone performance as a function of battery age.
