The iPhone XS and XR will get processor throttling feature with iOS 13.1
iphone XS and XR 在iOS 13.1会得到处理器弱化功能
Apple will add its processor throttling feature to the iPhone XS and XR next
week with the upcoming iOS 13.1 update. The feature, which was controversial
when first discovered in 2017, limits some iPhones’ performance to prevent
random shutdowns due to aging batteries. The feature is only supposed to be
active when a phone has an older battery, but those affected have previously
complained about noticeable slowdowns of their devices when it happens.
苹果在iOS 13.1对iphone XS & XR加入电池老化时处理器的弱化功能。这个功能在
2017造成很大的争议，导致后来苹果送低价换电池。被弱化的iphone速度会非常慢
The feature was discovered when iPhone owners noticed that older phones would
speed up after a battery replacement. Apple eventually became more
transparent about the feature, detailing how it worked and temporarily
offering discounted battery replacements as a mea culpa. It later updated iOS
so that, even if your phone is at risk of random shutdowns, you can turn off
the processor throttling feature to regain full performance. The feature will
only be activated after the iPhone detects an unexpected shutdown because of
battery issues.
心得：
恭喜 iphone XS & XR获得弱化。
不过至少现在这个功能应该是可以自己关掉的～
不过有天你的手机突然变慢的时候可以去看一下
