Apple admits that older iPhones slow , says it’s to prevent battery issues
why my older iPhone older version get slow as they get older That is the question many iPhone owners ask themselves whenever a new iPhone model is released or they install a new software update on an older iPhone Many customers have long suspected that Apple slows down older iPhones to encourage people to upgrade, Apple confirmed Wednesday that it’s true older models will slow as they get older and older, saying that such
slowdowns were a deliberate effort to keep older phones running longer as the battery wears down—not a push to buy a new model.
“Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components,” Apple’s statement said Lithium batteries degrade over time because of what happens during the charging and discharging cycle During both those events, lithium ions migrate through the material forming the battery Lithium-ion batteries degrade with use Studies using electron microscopes have shown that each time the ions do this they make tiny changes to the physical structure of that electrolyte.
The effect is like “rust creeping unevenly across steel”, according to one scientist who has studied the phenomenon The changes effectively erode the material so it can hold less of a charge and can hamper its ability to provide a steady power supply Higher voltages make the erosion happen more quickly, as do higher temperatures.
Apple software aims to avoid unexpected shutdowns on older phones and this, in turn, can slow the phones. Apple said last year it had released a feature for iPhone 6, iPhone 6s and iPhone SE to help avoid such blackouts. With the recent iOS 11.2 operating upgrades, it’s extending that feature to iPhone 7 and plans to add it to future products Apple’s confirmation comes after Reddit users noticed that their devices were getting slower as the batteries in their iPhones got weaker.
Subsequent tests on older iPhone 6S and iPhone 7 and recent versions of Apple’s iOS software by John Poole, founder of the popular Geekbench benchmarking tool for measuring performance on devices, added weight that this was indeed happening.Who does this effect? iPhone 6, 6S, and 7 users at the moment, but it will likely
continue for all future iPhones until further notice. Something to note about the iPhone 7: with the A10 chip, it has low power and high power cores.
The low power cores are used 90% of the time, and should stay at full speed, so you won’t notice any slowdown except in intensive programs such as benchmarks, demanding games, video editing, etc Some Reddit users reported that replacing the battery in their older phones sped things up iPhones, like many recent Android devices, do not have batteries that can be easily replaced by users.
Apple charges $79 for a new battery for those without its AppleCare warranty protection, a cheaper cost than several hundred dollars for a new device. here apple official statement “Our goal is to deliver the best experience for customers, which includes overall performance and prolonging the life of their devices. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components.
“Last year we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting down during these conditions. We’ve now extended that feature to iPhone 7 with iOS 11.2, and plan to add support for other products in the future.”
