The older the phone gets, the poorer the performance gets.
Primate Labs, a company that built and app for measuring the speed of an iPhone’s processor, released data a few days ago, showing that the performance of the iPhone 6s and 7 models dipped as they aged.
Apple admitted it on Wednesday December 20.
They said they reduce power demands on the phone, which in turn slows down the processor. In the statement released by Apple, the problem is due to the fact that all Lithium-ion batteries degrade and have problems supplying as much juice as the grow older and accumulating charging cycles.
“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.”
When the iPhone processor makes a big current draw from a flagging battery, according to Apple, the battery can deliver the current in spikes that can potentially damage the phone’s electronics.
All you have to do is replace the old battery for $79. And guess what doesn’t have a warranty? The battery. lol. That’s besides the fact that repair advocates have complained over and over that Apple makes it difficult for users to replace batteries on their own.
