DxOMark recently evaluated the autonomy and charging performance of Apple’s latest flagship, the iPhone 15 Pro Max. The lab’s findings show that in several categories, the new device trails behind a model released two years earlier.
Specifically, the iPhone 15 Pro Max packs a 4,441 mAh battery and supports 30W wired charging. In endurance tests under heavy use, the phone lasted about 43 hours, while under moderate usage it extended to roughly 69 hours. This combination placed the device third within the premium segment, yet it ranked 19th when considering the overall device lineup. These numbers reflect how factors beyond sheer capacity, such as processor efficiency and thermal management, influence real-world performance for Canadian and American users alike (DxOMark results with attribution).
Charging performance tells its own story. With wired charging, the iPhone 15 Pro Max reached 53% in 30 minutes and hit full capacity in 121 minutes. In wireless mode, it hit 30% in half an hour and achieved 100% in 157 minutes. On the premium device scale, this performance placed the phone at 32nd, and it sat 113th out of 163 on the broader spectrum. These metrics emphasize how charging speed can vary significantly between wired and wireless methods, a consideration relevant to everyday charging habits in North American households (DxOMark results with attribution).
The broader test profile shows a fast discharge in certain scenarios, even as other aspects of the iPhone 15 Pro Max were praised. The device earned 148 points for autonomy, 116 for charging speed, and 134 for energy efficiency, culminating in a 29th-place overall score. By comparison, the iPhone 13 Pro Max earned 136 points and stands ahead of the new model in overall terms due to a more favorable balance of autonomy and energy use, though the iPhone 15 Pro Max delivered stronger charging efficiency. These insights help shoppers in Canada and the United States weigh the tradeoffs between modern efficiency and faster charger support, especially for users who rely on lengthy sessions away from power sources (DxOMark results with attribution).
Market pricing for the earlier powerhouse models has seen notable fluctuations, with the price dynamics of Apple’s flagship reflecting shifts in demand and regional exchange rates. Observers in North America may notice price pressures that influence purchasing decisions as promotions and carrier plans evolve, making it worthwhile to compare current offers against the device’s battery life, charging speed, and energy management characteristics highlighted by DxOMark testing (DxOMark results with attribution).
