Title:Apple just gave owners of older iPhones a great reason not to upgrade

Apple announced during its WWDC keynote on Monday that iOS 12, the latest version of its mobile operating system coming later this year, would give a performance boost to older iPhones — and it could be a great reason to keep your older iPhone instead of buying a newer model.

苹果在周一WWDC的主旨发言中宣布，iOS12是苹果移动操作系统的最新版本，将于今年晚些时候推出，老iPhone的性能会促进iPhone的性能？这可能是维持旧iPhone而不是购买新型号的好理由。

Craig Federighi, Apple's senior vice president of software engineering, said iOS 12 would let the iPhone 6 Plus from 2014 — and presumably the smaller iPhone 6, as it has the same chip — open apps up to 40% faster than iOS 11. Federighi also said the keyboard would appear up to 50% faster and the camera app would open up to 70% faster when you slide from the bottom right of the lock screen.

苹果公司软件工程高级副总裁克雷格·费德里吉(Craig Federighi)表示，键盘速度将提高到50%，当您从锁屏幕右下方滑动时，相机应用程序将开放高达70%。

These three things are pretty significant in terms of how people use iPhones, and it'll make older iPhones feel a lot snappier than with iOS 11 or other previous versions. In fact, older iPhones could get such a significant performance boost that Apple itself just gave owners of older iPhones a great reason to put off upgrading to a newer model — that is, if Federighi's claims, which still need to be tested, are accurate. (For example, I'd test whether app performance is faster after I've opened the app.)

以上三件事对于人们如何使用iPhone来说都非常重要，而且比起iOS11或其他以前的版本，老iPhone感觉好多了。事实上，老iPhone的性能会大大提高，苹果自己也给了老iPhone用户一个推迟升级的伟大理由，也就是说，如果Federighi的说法还需要检验，是准确的（例如，在我打开应用程序之后，我测试应用程序性能是否更快。）

Federighi said these were just some examples of how iOS 12 would improve performance on the iPhone 6 Plus and other models as far back as the iPhone 5S, suggesting there are also other areas where older iPhones will be faster.

费德里吉说，这些只是iOS12将如何改善iPhone6Plus和其他iPhone5S模型的一些例子，这表明在其他一些地区，老iPhone的速度会更快。

The performance boost comes from the way iOS 12 communicates with the chip inside older iPhones. Federighi explained that iOS 12 would essentially tell your iPhone's chip to ramp up speed a lot faster to open an app compared with previous versions of iOS, which do so at a more gradual pace. iOS 12 will also tell your iPhone's chip to ramp down its speed more quickly when it's not needed, to save battery life.

iOS12与旧iPhone中的芯片进行交流，提高了性能。费德里吉解释说，iOS12将基本告诉你的iPhone芯片，与以前的iOS版本相比，开程序的速度要快得多，而iOS的启动速度要慢得多。iOS12还将告诉您的iPhone芯片在不需要时快速降速以挽救电池寿命。

You might be looking to upgrade to a newer iPhone because your older model's battery is dying a lot faster than it should. But if that's the main thing making you consider a new iPhone, you could save yourself a lot of money by getting its battery replaced at the Apple Store. If you have an iPhone 6 or later, Apple will replace your battery for $30 — that's $50 off the original $80 cost of battery replacements — through December.

您可能正想升级到一个更新的iPhone，因为老型号的电池比它预期的要快得多。但如果这就是你想换款新iPhone的主要方式，你可以用电池在苹果(Apple)商店更换电池来省下很多钱。如果你有iPhone6或者稍后，苹果将会以30美元取代你的电池？

But if you're tempted by the better cameras and extra features that come with newer iPhones, you have a fully legitimate reason to upgrade. Still, you should make sure they're worth the cost of upgrading.

但如果你受到拥有新型iPhone的更好的照相机和额外的功能的诱惑，你有完全合理的理由进行升级，不过，你应该确保它们值得升级。
