Apple's Alleged Throttling of Older iPhones With Degraded Batteries Causes Controversy
A Reddit post over the weekend has drawn a flurry of interest after an iPhone 6s owner reported that a battery replacement significantly increased the device's performance running iOS 11. The ensuing discussion thread, also picked up by readers in the MacRumors forum, has led to speculation that Apple intentionally slows down older phones to retain a full day's charge if the battery has degraded over time.
According to TeckFire, the author of the original Reddit post, their iPhone had been very slow after updating to iOS 11, especially compared to their brother's iPhone 6 Plus, so they decided to do some research with GeekBench and battery life apps, and ended up replacing the battery.
