I have an iPhone 8 and so far it’s been great, except for one thing. I was sure that the iPhone 8 supported fast charging, like up to 80% or something. but I barely notice much difference in terms of how quick it gets a charge compared to my iPhone 6s. I’ve checked Settings/Battery and tried Low Power Mode when on charge but that made no difference either. I looked elsewhere in Settings but didn’t see anything I can change to make it fast charge. So now I question myself and wonder:

  • Was I wrong about the whole fast charging thing?
  • Is it only the iPhone 8 Plus and iPhone X, or maybe just the iPhone X that supports fast charging?
  • Or is there just something I have to do to get it to fast charge?

Your assistance would be great!


Yes, all of this year's newly released iPhones (8, 8 Plus and X) support fast charging. And no, there’s no setting you need to enable for it to work.

And, just to clarify, by fast charging you can recharge your iPhone up to 50% (not 80%) within the first 30 minutes.

However, for fast charging to work you need to use a charger that provides enough power for it to fast charge, and the chargers bundled with your iPhone only deliver 5 watts of power at up to 1 amp. By way of example, an iPad charger delivers 12 watts of power at up to 2.1 amps. Note: I am not saying that an iPad charger will fast charge your iPhone 8, although it would certainly charge it quicker than the standard iPhone charger.

Instead, I refer to what Apple says you need for fast charging your iPhone:

Fast charging gives you a quick and convenient way to recharge your iPhone 8 or iPhone 8 Plus. Your iPhone fast charges up to 50 percent in 30 minutes when you use an Apple USB-C to Lightning cable and one of these adapters:

  • Apple 29W, 61W, or 87W USB-C Power Adapter
  • A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

For more info refer to: Fast charge your iPhone 8 or iPhone 8 Plus.

  • iMore has some nice third-party recommendations for fast charging, if you're not a fan of Apple's prices. – user24601 Oct 27 '17 at 8:05
