Apple Reveals iPhone Duo's Battery Capacity

MacRumors • Sun, 18 Oct 2026

Apple on Friday published an EU energy label for the iPhone Duo that reveals the device has a total battery capacity of 4,883 mAh. The document appears to confirm a previous leak that showed the iPhone Duo has 2,962 mAh and 1,921 mAh battery cells totaling 4,883 mAh. iPhone Duo is an eSIM-only device, so this battery capacity figure should apply worldwide, as there is no version of the device with a physical SIM card tray that would have a slightly smaller battery. For comparison, iFixit found the eSIM-only iPhone 18 Pro has a 4,288 mAh battery capacity, and the eSIM-only iPhone 18 Pro Max has a 5,567 mAh battery.

Mark Gurman: Apple Made 'Major Mistake' With iPhone Duo Pre-Orders

Despite knowing that the iPhone Duo would face "severe supply constraints" due to manufacturing challenges, Apple chose to begin iPhone Duo pre-orders on Friday instead of waiting until it had more inventory ready, according to Bloomberg 's Mark Gurman. In his Power On newsletter today , he called this decision a "major mistake." "Let me cut to the chase: Apple made a major mistake here," he said. "The company knew there would be severe supply constraints but went ahead with the launch anyway, apparently prioritizing a desire to get the device on the market early in its fiscal first quarter over satisfying demand. That will disappoint many of the early adopters most eager to buy it." Apple originally planned to launch the iPhone Duo in the U.S. and China only before expanding the device to other countries later, according to Gurman, but the company ultimately decided to start pre-orders in more than 70 countries simultaneously. Less than 30 minutes after pre-orders began, Apple's estimated shipping dates for the iPhone Duo slipped to around January 25 in most countries. Apple typically underpromises and overdelivers with its delivery dates, though, so hopefully some customers will end up having their shipping estimates bumped up at least slightly.
