r/iphone on Reddit: Maximum fast charging rate for iPhone 15 Pro?
September 15, 2023 -
Would I benefit from upgrading from my current 29W charging brick?
Also, do I need Apple’s own USB C cable, or would third party ones work just as fine?

Apple says on the iPhone 15 product page that the 50% in 30 minutes fast charging measurement they use was done with their 20w charger. There's nothing special about their charger or cables though, anything rated for that power will work fine. Testing conducted by Apple in August 2023 using preproduction iPhone 15 Pro and iPhone 15 Pro Max units and software and accessory Apple USB‑C Power Adapter (20W Model A2305). Fast‑charge testing conducted with drained iPhone units. Charge time varies with settings and environmental factors; actual results will vary.

So the 15 and 15 Plus only support USB-C 2.0 transfer speeds? And the 15 Pro and Pro Max support USB C 3.0 transfer speeds?
So what about charging speeds? Same 20W charging across all devices? What about non MFi certified cables or non apple branded cables? Would those still charge as fast?
And lastly, what classifies a cable as MFi cert.? Is it just that badge on the packaging that says " Made for iPhone | iPad | iPod "?

So the 15 and 15 Plus only support USB-C 2.0 transfer speeds? And the 15 Pro and Pro Max support USB C 3.0 transfer speeds? Correct So what about charging speeds? Same 20W charging across all devices? Yes What about non MFi certified cables or non apple branded cables? Would those still charge as fast? From what Apple's actually said so far, probably. There are/were rumours that MFI authentication on C-C cables might exist to restrict something, but apple's own site says all their existing C to C cables and power bricks will work for 20W and they never did anything like that with iPad's C, so seems like bullshit. And lastly, what classifies a cable as MFi cert.? Is it just that badge on the packaging that says " Made for iPhone | iPad | iPod "? Badge and possibly authentication with the e-marker chip.
