How to fast charge iPhone X, iPhone 8 and older models

Fast charging support in iPhone X and iPhone 8 is one of the most under-rated features of these new smartphones. This feature is so under-rated that Apple does not even market fast-charging on the main landing pages for iPhone X and iPhone 8 on their website. However, if you dive deep into the tech specifications pages for these phones, you will notice that they support fast-charge at a rate of 50% charge in 30 minutes. It is not as simple as it sounds though because you cannot fast charge these phones right out of the box. You need to spend more money and buy separate accessories to do so.

If you check the footnotes on these tech specifications pages, you will read the following:

Testing conducted by Apple in August 2017 using preproduction iPhone X units and software and accessory Apple USB-C Power Adapters (29W Model A1540, 61W Model A1718, 87W Model A1719)

Accessories you need to fast charge iPhone X and iPhone 8

Apple has not mentioned this clearly but for fast charging, you need a USB-C power adapter, which means that you also need a Lightning to USB-C cable to use it. A 1-meter USB-C to Lightning cable costs $29. Apple sells USB-C power adapters which also ship with the following Macs:

In total, to fast-charge your iOS device, you need to spend an extra $78, if you go with Apple’s accessories. If you already have any of the above MacBooks, you can save yourself the expense of buying a new adapter, however, you still need to shell out $29 for the cable.

If you get third-party accessories such as Anker USB Type-C with Power Delivery 30W USB Wall Charger, it will cost $27.99 while a 3-feet METRANS USB C to Lightning Cable will cost $8.99. At $36.98, this combination costs less than half of the cost of Apple’s accessories to fast-charge your devices.

One of the reasons that these chargers are more expensive than the 5W or 12W chargers is that they support Power Delivery. All of Apple’s new MacBooks shipping with USB-C Power Delivery adapters and work with third party chargers too. I personally use an Anker Power Delivery portable charger to charge my MacBook and it can be used to fast-charge the new iPhones. A must have accessory if you plan to fast-charge your devices on the go.

Verify if your iPhone X or iPhone 8 is fast-charging

Apple has not made a different notification or symbol for fast-charge, but there is a small indication you need to hear for: your iPhone will make the charging ‘ding’ sound twice when it is plugged using fast-charge accessories. You will have to make sure that your iPhone is not set to silent to hear the double ‘ding’ sounds.

Fastest wireless chargers for iPhone X and iPhone 8

To get the fastest charging speeds when using wireless charging with your iPhone, it is best to go with a product that supports 7.5W. One of the best solutions is Mophie’s Wireless Charge Pad which supports the 7.5W Qi wireless charging standard. However, if you are concerned about charging speed, note that wireless charging is more than 50% slower than fast-charging via a cable. Here’s a graph that illustrates this:

There are even 10W wireless chargers available now however, Apple has not included support for them in current iPhones. If Apple somehow adds support in a future iOS update, Mophie Charge Stream Pad+ 10W charger might be a good purchase for $59.95

If you have to chose between buying a cable and adapter to fast charge your iPhone versus buying a wireless charger, I’ll make the decision simple for you. If you have an iPad Pro, you can use fast-charge it too, using the cable and adapter. If you have modern MacBook or MacBook Pro, you can also share the adapter with it. Lastly, with a Lightning to USB-C cable, you can also connect your iPhone to your MacBook without a dongle.

Faster charging for iPhone 7, 6s and 6

There is no official ‘fast-charging’ for these old models, however, you can still charge them much faster if you use a 12W 2.1A adapter. This is the same adapter which ships with all iPads. If you already have an iPad and an older iPhone, you can start using the adapter right away. In case you are wondering, no, it will not damage your phone’s battery as Apple officially supports this on their website. You can use the 12W charger to charge other products like Apple Watch, AirPods and Siri Remote too.


  • No matter which iOS you use, you can always get a bit of boost in charging time by not using it when it’s plugged in.
  • You can also try and turning on battery saver mode. This will turn off automatically when your iPhone reaches 80% battery capacity.
  • This is extreme but you can put your iOS device to Airplane mode to get the best boost in charging speed. Because all your cellular, WiFi and Bluetooth connections are turned off, and your screen is also off when charging, there is literally no battery drain on your device. However, the drawback is that you get disconnected.
  • Always buy cables and chargers from reliable sources. A bad charger or cable can wreck your device.
