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.Related Roundup: iPhone DuoBuyer's Guide: iPhone Duo (Buy Now)Related Forum: iPhoneThis article, "Apple Reveals iPhone Duo's Battery Capacity" first appeared on MacRumors.comDiscuss this article in our forums ...read more read less
