iPhone 17 Delivers Faster Charging — 50% in Just 20 Minutes

ChargeLab’s latest tests confirm that Apple’s iPhone 17 lineup offers noticeably faster charging than its predecessor. Using Apple USB-C adapters ranging from 18W to 140W, the iPhone 17 achieved peak charging speeds of 27–28W, a solid improvement over the iPhone 16’s 23W. While not a massive leap, this clearly shows Apple has refined its USB-C charging performance.

The best charging speeds were recorded with adapters like the 29W USB-C, 30W USB-C, 35W Dual Port, 35W Compact Dual Port, 40W Dynamic Power (available in selected Southeast Asian countries), 61W USB-C, 67W USB-C, 70W USB-C, 96W USB-C, and 140W USB-C, highlighting strong compatibility with Apple accessories.

The iPhone 17 Pro performed even better, hitting up to 36W compared to the iPhone 16 Pro’s 30W. This aligns with Apple’s official claim that all iPhone 17 models can charge from 1% to 50% in just 20 minutes, down from 30 minutes previously.

MagSafe performance also improved — the iPhone 17 reached up to 29W using the latest MagSafe Charger, with a maximum 25W as per Apple’s specifications, offering more efficient wireless charging for users who prefer convenience.

Experts note that the speed boost is thanks to the new AVS standard in USB PD 3.2, which optimizes voltage delivery without relying on PPS, resulting in faster and safer charging. Apple also recommends using a high-quality USB-C cable to ensure full performance.

With all iPhone 17 models supporting this enhanced fast charging, Apple closes the gap with competitors who have long offered faster speeds. Most users will find this upgrade a welcome improvement in daily use.
