All smartphone batteries degrade over time so it is not unusual for Apple to be slowing down the performance of its older phones to help prolong their battery life, according to experts.
My own iPhone 6 experienced the auto-shutdown problem that Apple was addressing at times before I eventually upgraded, and a fix for that would've been welcome. Apple on Wednesday said a software feature released a year ago makes your phone operate more slowly to offset problems with its aging lithium ion battery.
The company went on to say that the iPhone 6 contains a feature that slows the phone down "only when needed to prevent the device from unexpectedly shutting down" due to a depleted battery.
The feature, which slows performance to demand less power, has been extended to iPhone 7 handsets with the latest iOS operating software and will be added to other Apple products "in the future", the spokesperson said.
"Apple's decision to not inform consumers that they could improve the performance speed of their devices by replacing their device's batteries reduced the effectiveness and usefulness of the subject telephones", the lawsuit said.
Modern technology changes so rapidly that the fancy phones that debut on a yearly basis become obsolete pretty much just as quickly, with companies like Apple touting new hardware that is sometimes multiple times more powerful than even recent iterations. John Poole, founder of the organization, said in a blog post that processors in iPhones slow down and decrease in performance as batteries age and lose capacity.
As pointed out on Reddit and confirmed by benchmarking app GeekBench, newer versions of iOS have introduced measures that may prevent phones from running at their would-be peak performance, in cases where the battery can't handle it, either from age or environmental issues.
However, the lawsuit said Apple chose to keep that information from consumers to nudge them toward buying newer model iPhones, including, most recently, its iPhone 8 and iPhone X models.
iPhone users can purchase a new battery for their older model if they don't want to fork over hundreds of dollars for an entirely new phone. Apple has long denied this assertion.
If you find your iPhone shutting down with a 30-40 percent charge or otherwise performing erratically, you might consider swapping out the battery.
