没有人愿意将智能手机插入充电线或无线充电器数小时。快速(Fast)充电现在很流行。本指南比较了可供 iPhone 用户使用的不同快速充电方法和配件。
最终目标是让您了解如何以最快、最安全和最有效的方式为 iPhone 充电。
哪些 iPhone 支持快速充电？
下面列出的 iPhone 型号支持快速充电。然而，并非所有这些快速充电的 iPhone 都附带快速充电配件。
- iPhone 8 系列 — iPhone 8 和 8 Plus
- iPhone X 系列 —(X Series —) iPhone X、iPhone XR、iPhone XS 和 iPhone XS Max
- iPhone SE (2020)
- iPhone 11系列 —(Series —) iPhone 11、iPhone 11 Pro和 iPhone 11 Pro Max
- iPhone 12系列 —(Series —) iPhone 12、iPhone 12 Mini、iPhone 12 Pro和 iPhone 12 Pro Max）
- iPhone 13系列 —(Series —) iPhone 13、iPhone 13 Mini、iPhone 13 Pro和 iPhone 13 Pro Max）
只有 iPhone 11 Pro和 iPhone 11 Pro Max随附快速充电适配器和USB-C转闪电(Lightning)连接线。
新款(New)iPhone 12 和 13 配备USB-C 数据(USB-C)线，因此您只需购买大功率电源适配器即可进行快速充电。
旧款 iPhone（iPhone X 系列及更早机型）包装中的 5W 充电器和USB-A转Lightning数据线无法提供快速充电速度。您需要购买新的快速充电适配器和电缆。
USB-C 壁式充电器(USB-C Wall Chargers)或电源(Power)适配器
尽管电源适配器有不同的规格（瓦数、电压等），但它们目前为 iPhone 和 iPad 提供了最快的充电选项。
对于 iPhone 12 和 iPhone 13 系列，您需要一个最小输出功率为 20 瓦的充电器。推荐使用Apple 20W USB电源适配器和MagSafe充电器（见下图）。您还需要真正的Lightning 数据(Lightning)线来体验快速充电速度。
要为 iPhone 11 系列及更早机型的设备快速充电，请使用额定功率为 18W 或更高的Apple USB-C转闪电连接线和充电适配器。(Lightning)
如果您不确定充电适配器的额定功率（或瓦数），请查看适配器底部、顶部或侧面的认证标签。
我们还应该提到MacBook的USB-C电源适配器将以最大速度为您的 iPhone 充电。这些适配器的最小额定功率通常为 60W 或更高。将正品USB-C转闪电(Lightning)连接线插入MacBook电源适配器，将其连接到 iPhone，然后观看它以闪电般的速度充电。
MagSafe 和 Magsafe Duo 充电器
MagSafe 充电(MagSafe Charging)（2021 年重新推出）是一种相对较新的为支持的 iPhone 机型充电的方法。MagSafe以无线充电技术的原理(principle of wireless charging technology)运行，只是它需要使用磁性附件。
目前，只有 iPhone 11 和 iPhone 12 系列支持MagSafe 无线(MagSafe Wireless)充电。这是因为它们是唯一在后盖中内置磁性充电线圈的 iPhone。MagSafe和MagSafe Duo充电器可为兼容的 iPhone 提供高达 15W 和 14W 的峰值功率。
为获得最佳无线充电速度，请将MagSafe或MagSafe Duo充电器插入 20 W（或更高）的 USB-C 电源适配器，然后将 iPhone 放在充电器上。在将电源适配器插入墙壁插座之前，请勿将 iPhone 放在MagSafe 充电器上。(MagSafe Charger)这将阻止MagSafe为您的 iPhone 提供最大功率。
将MagSafe 充电器(MagSafe Charger)插入壁式插座，打开电源，约 3-5 秒后将 iPhone 放在充电器上。请参阅此Apple 支持教程(Apple Support tutorial)以了解有关使用MagSafe 充电器(MagSafe Chargers)以及它们如何提供快速无线充电的更多信息。
注意：(Note:) Apple 29W(Apple 29W) USB-C 电源适配器与MagSafe Duo充电器不兼容。M
MagSafe提供的功率输出不如使用快速充电USB适配器和电缆的有线充电。然而，与传统的无线充电器相比，该技术提供了更好、更快、更高效的充电速度（在 iPhone 上）。有线还是无线充电(Wireless Charging)？
无线(Wireless)充电可能既方便又美观，但这并不是为 iPhone 充电的最快方式。这也不是最有效的充电方式。无线(Wireless)充电会产生更多热量，并可能导致您的 iPhone 变热。
如果您需要快速充电，那么电缆和电源砖是您的最佳选择。总而言之，这就是您所需要的：
- 高功率 USB-C 充电器（20W 或更高）或支持USB Power Delivery(USB Power Delivery) ( USB-PD )的第三方 USB-C 电源适配器。
- USB-C 转闪电数据线。
使用这些配件，您可以在大约 30 分钟内为兼容的快速充电 iPhone 从 0% 充电至 50%。有几个因素会阻碍您的 iPhone 高速充电，即使它支持快速充电。我们将在下一节重点介绍这些因素及其各自的解决方案。
更快地为 iPhone 充电的技巧
有时，即使您使用兼容或大功率的充电配件，您的 iPhone 也可能充电缓慢。以下是一些用于更快充电和改善电池健康的最佳 iPhone 充电做法。
1.使用正品充电配件(1. Use Authentic Charging Accessories)
使用来自Apple（在线）商店的“电源和电缆”(“Power & Cables” of Apple’s (online) store)的正品配件为您的 iPhone 充电，或访问您附近的Apple Store。劣质或仿冒的充电配件会使您的 iPhone 充电缓慢并缩短其电池寿命。
2.暂时禁用优化电池充电(2. Temporarily Disable Optimized Battery Charging)
优化电池充电(Battery Charging)是一项通过减少电池充满电的时间来减缓电池老化的功能。该功能在支持的设备上默认启用，这就是为什么你的 iPhone 在充电时有时会卡在 80% 的原因。
如果您需要更快地将 iPhone 充电至最大容量 (100%)，请禁用优化电池充电（暂时）。(Battery Charging)
转到设置(Settings)>电池(Battery)>电池健康(Battery Health)并打开优化电池充电(Optimized Battery Charging)。
3. 更新你的 iPhone(3. Update Your iPhone)
如果您的 iPhone 支持无线充电，但放置在 Qi 认证或MagSafe(MagSafe)充电器上时无法充电，则安装 iOS 更新可能会解决问题。iOS 14.2 修复了阻止 iPhone 在iOS 14.1中进行无线充电的问题。Apple 还发布了iOS 14.3 更新(iOS 14.3 update)，以解决阻止MagSafe Duo 充电器(MagSafe Duo Charger)以最大容量进行无线充电的问题。
因此，让您的 iPhone 保持更新可以修复阻止您的 iPhone 快速充电的隐藏错误和问题。
打开设置(Settings)应用程序，选择常规(General)，选择软件更新(Software Update)，然后安装适用于您 iPhone 的任何更新。
4. 冷却你的 iPhone(4. Cool Your iPhone)
温度是影响 iPhone 快速充电能力的另一个因素。热 iPhone(A hot iPhone)的充电速度会比在环境温度下运行的 iPhone 慢一些。在非常热的条件下不断为 iPhone 充电会永久缩短 iPhone 的电池寿命。
Apple 建议(Apple recommends)在环境温度介于 0-35 º C 之间使用(º C. Using)iPhone。在阳光直射或炎热的环境中使用 iPhone 可能会导致它变得太热。GPS跟踪或导航、游戏和 AR 应用程序等活动也会增加工作温度。
如果您的 iPhone 很热，请在充电前让它冷却——取下手机壳会有所帮助。更好(Better)的是，将其关闭几分钟或在关闭时充电。
5. 充电时不要使用 iPhone(5. Don’t Use iPhone While Charging)
除了电源适配器的功率外，系统活动也会影响手机的充电速度。充电时使用 iPhone 会增加其整体充电时间。
与蜂窝/移动相比， Wi-Fi(Wi-Fi)消耗的电量更少。切换到Wi-Fi或将 iPhone 置于飞行模式(Airplane Mode)以减少网络引起的电池消耗。启用低功耗模式(Low Power Mode)还可以通过减少耗电的后台活动来触发更快的充电。
USB-C充电(Charging)是最快的选择
移动电源还可以以快速充电速度为您的 iPhone 充电。购买移动电源(buying a power bank)时，请注意具有高功率输出（20 W 或更高）并支持USB-C Power Delivery 的产品(USB-C Power Delivery)。
顺便说一句，即使使用快速充电器，您的 iPhone 也无法以恒定或线性速度从 0-100% 充电。它首先会快速充电，然后随着电池接近充满电而减速。这两个充电阶段称为“快速充电”和“涓流充电”。请参阅我们的涓流充电解释(Trickle Charging explainer)器，以更好地了解为什么您的 iPhone 开始快速充电，然后缓慢充电。
Guide: What’s the Fastest Way to Charge Your iPhone?
No one wants to leave their smаrtphone plugged into a charging cable or on a wireless charger for hours. Fast chargіng is the in-thing now. This gυide compares the different fast-сharging methods and accessories availаble for iPhone owners.
The end goal is to educate you on the fastest, safest, and most efficient ways to charge your iPhone.
What iPhones Support Fast Charging?
The iPhone models listed below support fast charging. However, not all these fast-charging iPhones ship with fast-charging accessories.
- iPhone 8 series — iPhone 8 and 8 Plus
- iPhone X Series — iPhone X, iPhone XR, iPhone XS, and iPhone XS Max
- iPhone SE (2020)
- iPhone 11 Series — iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max
- iPhone 12 Series — iPhone 12, iPhone 12 Mini, iPhone 12 Pro, and iPhone 12 Pro Max)
- iPhone 13 Series — iPhone 13, iPhone 13 Mini, iPhone 13 Pro, and iPhone 13 Pro Max)
Only the iPhone 11 Pro and iPhone 11 Pro Max ship with a fast-charging adapter and USB-C to Lightning cable.
New iPhone 12 and 13 come with a USB-C cable, so you only have to purchase a high-wattage power adapter for fast charging.
The 5W charger and USB-A to Lightning cable in the packaging of older iPhone models (iPhone X series and earlier) cannot provide fast charging speed. You’ll need to buy new fast-charging adapters and cables.
USB-C Wall Chargers or Power Adapters
Although power adapters have different specifications (wattage, voltage, etc.), they currently provide the fastest charging options for iPhones and iPad.
For iPhone 12 and iPhone 13 series, you need a charger with a minimum power output of 20 watts. The Apple 20W USB power adapter and MagSafe charger (see image below) are recommended. You also need an authentic Lightning cable to experience fast charging speed.
To fast charge devices in the iPhone 11 series and older, use an Apple USB-C to Lightning cable and charging adapters with a power rating of 18W or higher.
If you’re unsure about the power rating (or wattage) of your charging adapter, check the certification label on the bottom, top, or side of the adapter.
We should also mention MacBook’s USB-C power adapters will charge your iPhone at maximum speed. These adapters usually have a minimum power rating of 60W and higher. Plug a genuine USB-C to Lightning cable into your MacBook power adapter, connect it to your iPhone, and watch it charge at lightning speed.
MagSafe and Magsafe Duo Chargers
MagSafe Charging (re-introduced in 2021) is a relatively new method of charging supported iPhone models. MagSafe operates on the principle of wireless charging technology, only that it entails using magnetically-attached accessories.
Currently, only the iPhone 11 and iPhone 12 series support MagSafe Wireless charging. That’s because they’re the only iPhones with magnetic charging coils built into the rear covering. MagSafe and MagSafe Duo chargers can deliver up to 15W and 14W of peak power to compatible iPhones.
For optimum wireless charging speed, plug the MagSafe or MagSafe Duo charger into a 20 W (or higher) USB-C power adapter and place your iPhone on the charger. Do not place your iPhone on the MagSafe Charger before plugging the power adapter into a wall socket. That’ll prevent MagSafe from delivering maximum power to your iPhone.
Plug the MagSafe Charger into a wall socket, turn on the power source, and place your iPhone on the charger after about 3-5 seconds. Refer to this Apple Support tutorial to learn more about using MagSafe Chargers and how they deliver fast wireless charging.
Note: The Apple 29W USB-C power adapter isn’t compatible with the MagSafe Duo charger.M
MagSafe doesn’t offer as much power output as wired charging using fast-charging USB adapters and cables. However, the technology delivers better, faster, and more efficient charging speeds (on iPhones) than conventional wireless chargers.Wired or Wireless Charging?
Wireless charging may be convenient and fancy, but it’s not the fastest way to charge your iPhone. It’s not the most efficient way to charge, either. Wireless charging generates more heat and might cause your iPhone to get warmer.
If fast charging is what you need, cables and power bricks are your best bet. Summarily, this is all you need:
- A high-wattage USB-C charger (20W or higher) or a third-party USB-C power adapter that supports USB Power Delivery (USB-PD).
- USB-C to Lightning cable.
With these accessories, you can charge compatible fast-charging iPhones from 0% to 50% in about 30 minutes. Several factors can hinder your iPhone from charging at high speed, even if it supports fast charging. We highlight these factors and their respective solutions in the next section.
Tips for Charging an iPhone Even Faster
Sometimes, your iPhone may charge slowly, even if you use compatible or high-power charging accessories. Here are some best iPhone charging practices for faster charging and improved battery health.
1. Use Authentic Charging Accessories
Charge your iPhone with the authentic accessories from the “Power & Cables” of Apple’s (online) store or visit an Apple Store near you. Bad or counterfeit charging accessories will charge your iPhone slowly and shorten its battery life.
2. Temporarily Disable Optimized Battery Charging
Optimized Battery Charging is a feature that slows down battery aging by reducing the time the battery spends fully charged. The feature is enabled by default on supported devices, and it’s the reason why your iPhone sometimes gets stuck on 80% when charging.
Disable Optimized Battery Charging (temporarily) if you need to charge your iPhone to maximum capacity (100%) quicker.
Go to Settings > Battery > Battery Health and toggle on Optimized Battery Charging.
3. Update Your iPhone
If your iPhone supports wireless charging but doesn’t charge when placed on a Qi-certified or MagSafe charger, installing an iOS update might fix the problem. The iOS 14.2 fixed issues preventing iPhones from charging wirelessly in iOS 14.1. Apple also released the iOS 14.3 update to fix issues preventing the MagSafe Duo Charger from charging wirelessly at maximum capacity.
So, keeping your iPhone updated can fix hidden bugs and issues preventing your iPhone from charging fast.
Open the Settings app, select General, select Software Update, and install any update available for your iPhone.
4. Cool Your iPhone
Temperature is another factor that impacts your iPhone’s ability to charge fast. A hot iPhone will charge a little slower than one operating at ambient temperature. Constantly charging an iPhone in very hot conditions can permanently shorten your iPhone battery life.
Apple recommends using iPhones where the ambient temperature is between 0-35 º C. Using your iPhone in direct sunlight or a hot environment can cause it to get too warm. Activities like GPS tracking or navigation, gaming, and AR apps can also increase operating temperature.
If your iPhone is remotely hot, leave it to cool before charging—removing your phone case can help. Better yet, turn it off for a few minutes or charge while it’s turned off.
5. Don’t Use iPhone While Charging
Aside from the wattage of your power adapter, system activity can affect your phone’s charging speed. Using your iPhone while charging will increase its overall charge time.
Wi-Fi consumes less power than cellular/mobile. Switch to Wi-Fi or put your iPhone in Airplane Mode to reduce network-induced battery drainage. Enabling Low Power Mode can also trigger faster charging by reducing power-intensive background activities.
USB-C Charging Is the Fastest Option
Power banks can also charge your iPhone at fast-charging speed. When buying a power bank, look out for products with high-wattage output (20 W or more) and support for USB-C Power Delivery.
By the way, your iPhone cannot charge from 0-100% at a constant or linear speed, even with a fast charger. It will charge rapidly at first, then slow down as the battery edges toward full charge. These two charging stages are known as “Fast Charge” and “Trickle Charge.” Refer to our Trickle Charging explainer to better understand why your iPhone charges fast at first and slowly afterward.
