The iPhone 18 Pro reaches 50 percent charge in around 15 minutes on a 60W USB-C adapter, according to Apple’s tech specs. That is five minutes quicker than the iPhone 17 Pro’s 20-minute claim with a 40W adapter, and half the roughly 30 minutes Apple quoted for the iPhone 16 Pro and iPhone 15 Pro.
Apple has phrased its fast-charge claim as time to 50 percent since the Lightning era, so the figure can be tracked from the iPhone 13 Pro to today. What changes each year is not only the number of minutes but the adapter Apple assumes, which is never in the box. This article puts the claims and the adapters side by side; our charger guide covers which adapter to buy.

| Model | Wired 50 percent claim | Adapter Apple cites | MagSafe | Qi or Qi2 | Port |
|---|---|---|---|---|---|
| iPhone 13 Pro | Around 30 minutes | 20W or higher | Up to 15W | Qi, 7.5W | Lightning, USB 2 |
| iPhone 14 Pro | Around 30 minutes | 20W or higher | Up to 15W | Qi, 7.5W | Lightning, USB 2 |
| iPhone 15 Pro | Around 30 minutes | 20W or higher | Up to 15W | Qi2, 15W | USB-C, USB 3 (10 Gb/s) |
| iPhone 16 Pro | Around 30 minutes | Not stated in the claim | Up to 25W with a 30W adapter | Qi2, 15W | USB-C, USB 3 (10 Gb/s) |
| iPhone 17 Pro | 20 minutes | 40W | Up to 25W; 50 percent in 30 minutes with a 30W adapter | Qi2, 25W | USB-C, USB 3 (10 Gb/s) |
| iPhone 18 Pro | Around 15 minutes | 60W | Up to 25W; 50 percent in 30 minutes with a 35W adapter | Qi2, 25W | USB-C, USB 3 (10 Gb/s) |
The wired claim sat at around 30 minutes for four generations, from the iPhone 13 Pro through the iPhone 16 Pro. The iPhone 17 Pro cut it to 20 minutes, and the iPhone 18 Pro to around 15. Over two years the time has halved.
The Pro Max follows the same path with one exception. Apple rated the iPhone 14 Pro Max at 50 percent in around 35 minutes rather than 30; the 15 Pro Max and 16 Pro Max returned to 30, the 17 Pro Max to 20, and the 18 Pro Max carries the same 15-minute claim as the smaller phone. Apple’s press release adds that five minutes on a cable gives the 18 Pro Max about seven hours of video playback.
The adapter each claim assumed: 20W, 40W and 60W
Apple’s 30-minute claims for the 13 Pro, 14 Pro and 15 Pro were written for a 20W or higher adapter. The 17 Pro’s 20-minute claim named a 40W adapter, and the 18 Pro’s 15-minute claim names a 60W adapter. In other words, the adapter Apple assumes has tripled in three years.
None of these adapters ship with the phone. Apple’s tech specs list the iPhone 18 Pro box contents as the phone with iOS 27 and a 1 m USB-C cable. The 60W adapter is sold separately, and Apple has not said what a lower-wattage adapter achieves on the new phone.
Wireless: MagSafe from 15W to 25W
MagSafe charging was rated at up to 15W on the 13 Pro, 14 Pro and 15 Pro. The iPhone 16 Pro raised it to 25W when paired with a 30W adapter, and the 17 Pro kept 25W while adding a wireless 50 percent claim of 30 minutes with a 30W adapter.
The iPhone 18 Pro holds MagSafe at up to 25W and repeats the 30-minute wireless claim, now with a 35W adapter. Qi2 has moved in step: 15W on the 15 Pro and 16 Pro, 25W on the 17 Pro and 18 Pro. On the older 13 Pro and 14 Pro, plain Qi charging was limited to 7.5W.
Port and cable
The iPhone 13 Pro and 14 Pro used Lightning at USB 2 speeds. Since the iPhone 15 Pro every Pro has used USB-C with USB 3 at up to 10 Gb/s, and the iPhone 18 Pro is no different.
