In an interview with Rebecca Jarvis of ABC News, Apple CEO Tim Cook touched on the ongoing controversy over power management features in older iPhones. He says that a future update will allow customers to turn off the power management feature that has caused older iPhones to slow down. Mac Rumors reports: According to Cook, when the power management features were first introduced in iOS 10.2.1, Apple did explain what was going on, but following the controversy, he believes Apple should have been clearer. The company did indeed mention that the shutdown issue was caused by uneven power delivery and explained that its power management system had been tweaked, but there was no clear notice that it could cause devices to operate more slowly at times. Cook says Apple "deeply apologizes" to customers who thought the company had other motivations. Apple is introducing better battery monitoring features in a future iOS update, and Cook says Apple will also allow customers to turn off the power management feature, which is new information that the company has not previously shared. The majority of the interview was focused on the announcements that Apple made today. The company plans to contribute $350 billion in the U.S. economy over the next five years, as well as issue employees a bonus of $2,500 of restricted stock units following the introduction of the new U.S. tax law.
