The 5W charger that Apple used to include with most iPhones isn't capable of fast charging. It's fine for overnight charging, but if you're looking for faster charging, you'll need to upgrade to a USB PD connection.

If you have an older iPad charger, you can use it for faster iPhone charging, as it should cut the charging time in half. However, these older chargers still use USB-A connections and don't support the USB PD standard, so they're not technically fast charging.

Apple brought true fast charging to the iPhone 8 lineup in 2017, but continued to include the 5W charger with most iPhones. The only iPhone models to include the USB-C fast charger in the box were the iPhone 11 Pro and iPhone 11 Pro Max.

Here's a list of the maximum fast charging speeds for various iPhone models that can run iOS 18:

Note that Apple claims fast charging can refill up to 50% of your iPhone's battery in just 30 minutes, which can be a huge time-saver, especially during the day.

Troubleshooting is a crucial part of the process when dealing with technical issues.

In some cases, updating your device's software can resolve the issue.

If your iPhone is fast charging, you may notice a rapid increase in battery percentage, especially within the initial few moments of charging. This can be a dramatic spike, especially when using fast charging equipment.

You can test if your iPhone is fast charging by checking if it can be charged up to 50% within 30 minutes. If it can, chances are, your iPhone is indeed fast charging.

One way to confirm fast charging is to listen for the double vibration or hear the "ding" twice when your iPhone plugs into a fast charger. This is a common indicator that your iPhone is fast charging.

To monitor the charging speed anytime, you can use a USB power meter to read charging watts. This will give you a clear indication of whether your iPhone is fast charging or not.

Here are some iPhone models that can fast charge, according to Apple's specifications:

Keep in mind that fast charging speeds can vary depending on the iPhone model and the charging equipment used.

To take advantage of fast charging on your iPhone, you'll need a few specific devices. Any iPhone model from the iPhone 8 onwards supports fast charging.

You'll need a USB-C power adapter with at least 18 watts of output. Apple's 20-watt power adapter is a good choice, but third-party chargers can also work as long as they support the necessary output.

A USB-C to Lightning cable is also crucial for achieving higher charging speeds. For iPhones before the iPhone 15, you'll need a USB-C to Lightning cable, while for iPhone 15 and newer models, a USB-C to USB-C cable is required.

Here's a summary of the devices you'll need for fast charging:

With these devices, you'll be able to fast charge your iPhone and enjoy a more convenient and efficient charging experience.

If you're looking to fast charge your iPhone, you'll need a few specific accessories. Apple's official fast charger is a new cable and charging brick for your device, but it's not the cheapest option.

To fast charge your iPhone, you'll need a fast-charging phone and a power adapter. Apple provides power adapters of various wattages, including 20W, 30W, 35W, 45W, 60W, 70W, 85W, and 96W. These adapters are larger and heavier, but they can shorten your iPhone's charging time.

You'll also need a USB-C to Lightning cable if you want to charge your iPhone with the fast-charging adapters from Apple. The charging power and speed depend on the minimum output of the two devices.

A 20-watt adapter with a USB-C port is a good option for fast charging your iPhone. Apple's 20-watt adapter is priced at $29, but you may already have a compatible adapter if you have a newer MacBook or iPad.

Here are some key points to keep in mind when choosing a charger and accessories for fast charging your iPhone:

If you're looking for a charger for your iPhone, you've got plenty of options. Apple sells its own fast charger, which is a cable and charging brick combo that's designed specifically for your device.

A 20W fast charger is a good starting point, and it's not a bad choice if you want to fast-charge your iPhone 12 or earlier iPhone model. However, if you want to charge your iPhone 16 Pro or Pro Max faster, you may want to consider a 30W or higher charger.

You don't need a super-powerful charger to fast-charge your iPhone, though. A 20W charger will still get the job done, and it's a good option if you're on a budget.

To fast-charge your iPhone, you'll need a fast-charging cable, a power adapter, and a device that supports fast charging. Apple's official fast chargers include power adapters of 20W, 30W, 35W, 45W, 60W, 70W, 85W, and 96W.

Here's a quick rundown of the different power adapters available:

Keep in mind that you'll need a USB-C to Lightning cable to charge your iPhone with the fast-charging adapters from Apple. The charging power and speed will depend on the minimum output of the two devices, so even if you use a 96W charger, the maximum charging capacity will be limited to 18W if your iPhone only supports 18W fast charging.

PD and PDO are two important terms to understand when it comes to fast charging your iPhone.

The USB Power Delivery standard is a relatively new fast charging standard adopted by Apple, and it provides slightly higher power output, up to 100W maximum.

It's used in tablets and laptops as well, which is why you'll see greater adoption of this standard in more devices in the future.

A USB power delivery charger or power adapter can deliver a range of voltages, from 5V to 20V, with each voltage being named PDO1, PDO2, PDO3, and so on.

The PDOs differ between different chargers, like the Apple 29W PD charger, which can only deliver two types of voltage: 5V and 14.5V.

This means that before the charger delivers power to your iPhone, they negotiate and find the voltage that both devices support.

iPhone PD fast charging will usually involve both PDO1 and PDO2 from the power adapter, with PDO2 delivering an initial boost of power for a short period.

If you're looking to fast-charge your iPhone, you'll need a 20-watt adapter with a USB-C port, which can be purchased for $29 from Apple.

Apple's official 20-watt USB-C power adapter is a good option for fast-charging your iPhone at a decent speed.

You may already have a power adapter that can handle all your fast-charging needs if you have a newer MacBook or iPad, as almost all MacBooks and iPads sold in the past few years use USB-C-compatible charging blocks.

A more powerful adapter can't force your iPhone to accept a wattage that's too high for it to handle, so if you have a MacBook Pro, you likely have a charger that's even more powerful than the 29W or 30W varieties.

Apple's 61W and 87W versions are safe to use with the iPhone, but keep in mind that your iPhone doesn't draw any more power than it needs.

If you're buying an adapter just for fast charging, there's no need to buy an adapter stronger than 30W, as even the newest iPhones can only handle a 29W charge under ideal conditions.

The iPhone 8, iPhone 8 Plus, and later iPhone models support the USB Power Delivery (PD) fast charging standards, but their fast-charging power varies, with the iPhone 8 having the lowest power of 12W.

A unique perspective: Iphone 8 plus vs Iphone X

Later iPhone models can handle up to 18W, and the iPhone 11 models have been upgraded to 22W.

The speed at which your iPhone charges depends on the model, with the iPhone charging faster when its battery life is in the red (somewhere between 1% and 10%).

Here's a list of maximum fast charging speeds for every iPhone model that can run iOS 18:

To fully leverage the fast charging capabilities of your iPhone, make sure you're using the right power adapter and cable.
