Synopsis

The iPhone 17 series introduces faster charging, with the Pro models leading the way when paired with Apple's Dynamic Power Charger. Testing reveals the iPhone 17 Pro charges the quickest, reaching 72% in 30 minutes. However, the iPhone Air lags behind despite its smaller battery. Battery life improvements are also noted, particularly in the Pro Max.

The iPhone 17 series has landed with promises of faster charging, longer battery life, and Apple’s most efficient power system yet. But how do those claims hold up in the real world?

iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air are put to test using Apple’s new 40W Dynamic Power Charger, and the results show some clear winners and losers.


How fast does each iPhone 17 model charge?


Apple promised quicker charging this year, and for the most part, the numbers deliver. The standard iPhone 17 was surprisingly one of the fastest, hitting 39% in 15 minutes and 71% in half an hour, as per a report by Toms’s Guide.

The iPhone Air, despite having the smallest battery, actually lags behind, managing 30% after 15 minutes and 55% after 30. That puts it slower than last year’s iPhone 16, which hit 57% in the same timeframe.


The iPhone 17 Pro edges past the regular model, topping out at 40% in 15 minutes and 72% after 30, a big step up from the iPhone 16 Pro’s 29% and 56%.

The iPhone 17 Pro Max, with its massive battery, charges slightly slower, reaching 35% in 15 minutes and 64% after 30. Still, it’s noticeably better than the iPhone 16 Pro Max, which managed just 55% in the same period.


Does battery life change how often you’ll need to recharge?


The new lineup has also seen improvements in battery endurance. The iPhone 17 Pro Max now runs for nearly 18 hours on a single charge, while the iPhone 17 Pro delivers over 15 hours, as per a report by Toms’s Guide.

But the thinner iPhone 17 and iPhone Air clock in at 12 hours 47 minutes and 12 hours 2 minutes, respectively. These smaller batteries mean you’ll likely lean on fast charging more often, though ironically, the Air is also the slowest to refill, as per a report by Toms’s Guide.


What charger do you need for the best results?

There’s one catch to Apple’s new charging promise: you’ll need the company’s $39 Dynamic Power Charger. This accessory supports the USB Power Delivery 3.2 standard with Adjustable Voltage Supply (AVS), unlocking the advertised speeds. Without it, you won’t hit the same numbers.

It’s a little more complicated than most people would like, but for those who rely on quick top-ups, Apple’s charger is the only way to go, as per a report by Toms’s Guide.

The iPhone 17 series is a clear upgrade in charging performance, especially compared to last year’s models. The Pro models stand out with the fastest recharge speeds, while the iPhone Air lags despite its smaller battery. With the right charger, though, you can finally power up your iPhone in record time.
