Official EU Energy Label Confirms 4,883 mAh Battery Capacity for Apple’s Upcoming iPhone Duo

The official regulatory disclosure aligns precisely with earlier industry reports and hardware leaks that surfaced several months prior to the filing. Specifically, the energy label document validates details from a July 10, 2026 report revealing that the iPhone Duo utilizes a split dual-cell battery architecture consisting of a 2,962 mAh primary cell and a 1,921 mAh secondary cell. When combined, these two individual internal power components yield the exact total capacity of 4,883 mAh now cited in Apple’s European Union energy label filing.
