This was very obvious to everyone. Despite this Apple still didn't admit it. Not anymore. Apple admits to slowing down older phones, but only for your own good!
The last couple of iPhone updates have made the phones move much slower and additionally the battery is drained much quicker. Finally Apple admits that we aren't insane.
"Apple on Wednesday said a software feature released last year makes your phone operate more slowly to offset problems with its aging lithium ion battery," CNet.com stated in an article. "As batteries get older, they don't hold their charges as well as newer batteries, and can have worse problems when the charge is low or the temperature is cold."
The aging battery means your phone could have trouble operating or might unexpectedly shut down, like happened to the iPhone 6 and 6S last year. The processors in those devices wanted to hit faster speeds, but their batteries couldn't handle the demand, prompting some phones to simply switch themselves off.
To address that, Apple's iOS software, starting with last year's iOS 10.2.1, included better power management capabilities, the company says. The operating system slows down your device to prevent it from shutting down, Apple says, but only in cases of cold temperature, a low battery charge or very old batteries.
Last year's software applied to the iPhone 6 and 6 Plus, 6S and 6S Plus and SE. This year's iOS 11.2 extended the feature to the iPhone 7 and 7 Plus. It will be applied to other Apple devices in the future.
Apple has messed with every version of the iPhone except the two that were just released the 8 and the X. But it was to help the users!
Per Apple's 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," Apple said in a statement.
"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."
Geekbench basically forced Apple into the admission with an in-depth analysis of the "fix" that was used to keep iPhones from shutting down suddenly.
It's all a part of the Apple business plan. They brick your old phone because they know you will come rushing in to buy another one.
