About every week in the past, a massively fashionable and extensively circulated thread on Reddit posited that Apple purposely slows down efficiency on iPhones with older batteries. The foundation for the seemingly sensational declare stemmed from a person who changed his iPhone 6s battery with a model new one and rapidly seen that efficiency was a lot improved. After performing some Geekbench testing with each the older battery and the brand new one, his suspicions had been backed up by chilly laborious knowledge.
Diving into the matter, Geekbench founder John Poole just lately determined to do some testing of his personal by measuring system efficiency on the iPhone 6s and iPhone 7 working numerous iterations of iOS. Poole subsequently discovered some attention-grabbing efficiency degradation when going from iOS 10.2.zero and 10.2.1.
So what precisely is happening right here? Is it attainable that each one the cynics who’ve been claiming that Apple engages in deliberate obsolescence have been proper all alongside? That’s one thing of a stretch, however the actuality is that Apple has been limiting efficiency on sure iPhone fashions with older and lower-capacity batteries as a method to stop sudden shutdowns through sudden battery drainage.
First, it seems the issue is widespread, and can solely worsen as telephones (and their batteries) proceed to age. See, for instance, the distinction between the distribution of iPhone 6s scores between 10.2.1 and 11.2.zero.
Second, the issue is due, partially, to a change in iOS. The distinction between 10.2.zero and 10.2.1 is just too abrupt to be only a perform of battery situation. I imagine (as do others) that Apple launched a change to restrict efficiency when battery situation decreases previous a sure level.
Shedding some additional mild on the matter, Poole cites the next clarification that appeared on Reddit:
Because degraded batteries final a lot much less and find yourself with a decrease voltage Apple’s answer was to scale down CPU efficiency, it doesn’t clear up something and is a foul expertise… but it surely’s higher than having your system shutdown at 40% while you want it probably the most.
In quick, Apple is seemingly curbing system efficiency within the curiosity of improved battery life. The finish outcome, although, is that almost all customers can be below the impression that their telephone is slowing down and that it might be time to improve.
