Which iPhone 18 Model Should You Buy?

你应该购买哪款 iPhone 18？

With a fresh folding form factor, the new iPhone Duo is Apple’s most radical redesign in years. It lands alongside the more familiar-looking iPhone 18 Pro and iPhone 18 Pro Max. There’s no regular iPhone 18, or at least, not yet. Rumors suggest we may see a more affordable base model, perhaps flanked by an iPhone 18e and a second-generation iPhone Air, in spring 2027.

凭借全新的折叠外形，新款 iPhone Duo 是苹果多年来最激进的设计变革。它与外观更熟悉的 iPhone 18 Pro 和 iPhone 18 Pro Max 同步登场。目前还没有普通版的 iPhone 18，或者至少现在还没有。传闻称，我们可能会在 2027 年春季看到一款价格更亲民的基础机型，或许还会伴随 iPhone 18e 和第二代 iPhone Air 一同发布。

The two new Pro iPhones are available to preorder on September 12 and ship on September 18. You can preorder the iPhone Duo from October 16, ahead of a full release on October 23. But which iPhone 18 model is right for you? I’ll break down the differences and what these phones have in common, so you can choose with confidence.

两款全新的 Pro 系列 iPhone 将于 9 月 12 日开启预购，并于 9 月 18 日发货。iPhone Duo 则于 10 月 16 日开启预购，并于 10 月 23 日正式发售。但哪款 iPhone 18 最适合你呢？我将详细分析它们的区别与共同点，助你做出明智的选择。

Why You Might Not Need to Upgrade

为什么你可能不需要升级

Before you drop all those hard-earned dollars, remember that you probably don’t need the latest iPhone. If you have an older iPhone, Apple does a good job of updating the software (the iPhone 11 Pro is still supported), and for hardware issues, your iPhone might be repairable; maybe it needs a battery replacement or these troubleshooting tips. Don’t feel like you have to spring for Apple’s shiny new thing.

在你掏出辛苦赚来的钱之前，请记住，你可能并不需要最新的 iPhone。如果你使用的是旧款 iPhone，苹果在软件更新方面做得很好（iPhone 11 Pro 至今仍受支持）；如果遇到硬件问题，你的 iPhone 可能还可以维修；也许它只是需要更换电池，或者参考一些故障排除建议。不要觉得非得去追逐苹果的新品。

Sadly, Apple raised iPhone Pro prices this year, so both models are $100 more expensive than the iPhone 17 Pro series. If you’re set on upgrading, consider raising funds by selling your old iPhone. Just be sure to back up your iPhone, and factory reset it before you sell or give it away.

遗憾的是，苹果今年提高了 iPhone Pro 的价格，两款机型都比 iPhone 17 Pro 系列贵了 100 美元。如果你执意要升级，可以考虑通过出售旧 iPhone 来回笼资金。但在出售或赠送之前，请务必备份好你的 iPhone 并恢复出厂设置。

The Similarities

共同点

We’ll start by looking at what’s the same across the iPhone 18 models this year. 我们将首先看看今年所有 iPhone 18 机型的共同之处。

The Processor 处理器 All three new iPhones have Apple’s A20 Pro chip inside, and, you guessed it, this is Apple’s most powerful chip ever. Now, iPhones are already the most capable phones for raw compute power, but the A20 Pro promises a significant jump in performance (around 20 percent faster and 30 percent more efficient than the last generation). It also packs a new neural engine to power on-device AI and a new thermal design with a larger vapor chamber to keep things cool.

三款新 iPhone 均搭载了苹果 A20 Pro 芯片，正如你所料，这是苹果有史以来最强大的芯片。虽然 iPhone 本身在原始计算能力上已经是性能最强的手机，但 A20 Pro 承诺带来显著的性能提升（比上一代快约 20%，能效提升约 30%）。它还配备了全新的神经网络引擎以支持端侧 AI，并采用了带有更大均热板的全新散热设计，以保持机身凉爽。

The Display 显示屏 While they come in different sizes and the Duo has two, every iPhone features an OLED screen that Apple calls a Super Retina XDR display. They also have ProMotion technology, otherwise known as a 120-Hz refresh rate. These adaptive refresh rates can drop as low as 1 Hz when there’s little activity on the screen, enabling features like the always-on display without draining the battery too much.

虽然它们的尺寸各异，且 Duo 拥有两块屏幕，但每款 iPhone 都配备了苹果称之为“超视网膜 XDR 显示屏”的 OLED 屏幕。它们还具备 ProMotion 技术，即 120Hz 刷新率。当屏幕活动较少时，这些自适应刷新率可降至 1Hz，从而在不消耗过多电量的情况下实现全天候显示等功能。

The Usual Specs 常规规格 All the phones have an IP68 rating for water and dust resistance. They all come in four storage options (256 GB, 512 GB, 1 TB, or 2 TB), support Qi2 magnetic wireless charging (MagSafe), USB-C 3.2, Dual SIM, Wi-Fi 7, Bluetooth 6, Thread, and Ultra-Wideband (UWB). It also has Siri AI, Apple Intelligence, Emergency SOS via Satellite, and Crash Detection.

所有机型均具备 IP68 级防尘防水性能。它们都提供四种存储容量（256GB、512GB、1TB 或 2TB），支持 Qi2 磁吸无线充电（MagSafe）、USB-C 3.2、双卡双待、Wi-Fi 7、蓝牙 6、Thread 和超宽带（UWB）技术。此外，它们还配备了 Siri AI、Apple Intelligence、卫星紧急求助功能以及车祸检测功能。
