After a thread appeared on Reddit earlier this month saying that your older iPhone could get a speed boost if you replace the battery, some “Apple is evil” conspiracy theorists went into overdrive claiming Apple was slowing down old iPhones in order to get you to upgrade to new devices.
本月早些時候，Reddit 網(wǎng)站披露一條消息，該消息稱，給蘋果手機(jī)換上新電池會提升手機(jī)的速度，這下就給了“蘋果陰謀論”分子們興風(fēng)作浪的機(jī)會，他們說蘋果公司之所以這樣做是為了讓人們?nèi)ベI更新一代的手機(jī)。

As TechCrunch points out, this motive would be absurd. But Apple did confirm to the site that they do slow down older iPhones with battery issues in order to provide a better user experience:
據(jù)科技博客報道，這個說法是很荒謬的。但是蘋果方面稱他們是有意減緩蘋果手機(jī)的運(yùn)行速度，為了給用戶帶來更好的體驗。具體說法如下：

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.[/en
]我們的目標(biāo)是為了給用戶提供更好的體驗，其中包括提升整體性能以及延長手機(jī)的壽命。在寒冷的環(huán)境中，鋰電池的供電能力就稍顯不足，無法滿足如今用戶的需求。隨著電池老化，其儲電能力也隨之下降，因此，設(shè)備會自動關(guān)機(jī)來保護(hù)其零件。

[en]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.

去年我們針對iPhone 6, iPhone 6s 以及 iPhone SE在某些情況下突然關(guān)機(jī)推出了一些功能，如今的iPhone 7也會繼續(xù)沿用這些功能。
