Apple company has confirmed the suspicions of several iPhone owners by revealing it can deliberately slow down some models of the apple iphone as they age.
Numerous customers have long suspected that will Apple slows down older iPhones in order to encourage people to upgrade.
The company has now said it does reduce some models as they age, yet only because the phones’ battery functionality diminishes over time.
Apple company said it wanted to “prolong the particular life” of customers’ devices.
The practice was verified after a customer shared performance lab tests on Reddit, suggesting their apple iphone 6S had slowed down considerably since it had aged but had all of a sudden sped up again after the battery have been replaced.
“I utilized my brother’s iPhone 6 In addition, and his was faster than my own? This is when I knew something has been wrong, ” wrote TeckFire .
Technology website Geekbench then analysed several iPhones operating different versions of the iOS os and found some of them did certainly appear to have been deliberately slowed down.
What was Apple’s response?
Apple has now confirmed that it produced changes to iOS to manage aging lithium-ion batteries in some devices, because the batteries’ performance diminishes over time.
“Lithium-ion batteries become much less capable of supplying peak current needs when in cold conditions, [when they] have a low battery cost or as they age over time, which could result in the device unexpectedly shutting right down to protect its electronic components, inch the company said.
“Last year, we released a feature regarding iPhone 6, iPhone 6s plus iPhone SE to smooth out the particular instantaneous peaks only when needed to avoid the device from unexpectedly shutting lower during these conditions.
“We’ve now extended that function to iPhone 7 with iOS 11. 2, and plan to include support for other products later on.
“Our goal would be to deliver the best experience for customers. inch
Why do lithium-ion electric batteries degrade?
Lithium electric batteries degrade over time because of what happens throughout the charging and discharging cycle.
During both those activities, lithium ions migrate through the materials forming the battery.
Studies making use of electron microscopes have shown that each period the ions do this they make small changes to the physical structure of this electrolyte.
The effect is similar to “rust creeping unevenly across steel”, according to one scientist who has analyzed the phenomenon.
The particular changes effectively erode the materials so it can hold less of a cost and can hamper its ability to give a steady power supply.
Increased voltages make the erosion happen faster, as do higher temperatures.
Ought to Apple have told customers?
“By choosing to apply this quietly, it appears more nefarious than it really is. That doesn’t engender believe in, ” wrote developer and tumblr Chip Heer .
“Apple has long been very good about managing expectations… this is an instance where they blew it. Needlessly, I think. ”
Replacing an old battery with the affected models should return the telephone to its former speed. Doing this costs £ 79 in the UK plus $79 (£ 59) in the US.
“They should be more clear about it, ” said Chris Eco-friendly from the tech consultancy Bright Bee.
“You’re taking away functionality that somebody has paid for. When you are going to slow down the phone over time, you need to explain why it is happening, therefore people understand it is ultimately for his or her benefit.
“But I actually do see where they’re coming from. Simply by slowing the phone, it does help reduce the problem of the diminishing battery. inch
