No, there is nothing that indicates fast charging will reduce battery lie.


Fast charge your iPhone and iPad

Use fast charge with certain iPhone or iPad models. You can recharge your iPhone up to 50 percent battery in around 30 minutes.


You can fast charge these iPhone and iPad models:

  • iPhone 8, iPhone 8 Plus, and later
  • iPad Pro 12.9-inch (1st generation and later)
  • iPad Pro 11-inch (1st generation and later)
  • iPad Pro 10.5-inch
  • iPad Air (3rd generation)
  • iPad mini (5th generation)

With iPhone, you can fast charge up to 50 percent battery in around 30 minutes.*

Fast charging works when you use an Apple USB-C to Lightning cable and one of these adapters:

  • Apple 18W, 29W, 30W, 61W, 87W, or 96W USB-C Power Adapter
  • A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD)

If you're not sure which Apple Power Adapter you have, check the wattage on the bottom of the adapter:

Your friend is wrong. Fast charging will not reduce the battery life. Battery life, on the other hand, gets reduced regardless of how you charge your battery as time elapses. That is the nature of a Lithium battery. Enjoy your iPhone. Charge your battery whenever you want. You can fast charge it with the charger that came with your iPhone or any other approved chargers. Your battery will last about 2+ years and then you will need to get it replaced as if begins to affect peak performance on your iPhone.
