iPhone Duo battery capacity listed at 4,883 mAh
An EU energy label published by Apple appears to support an earlier leak describing two battery cells in the device.
Apple has disclosed a total battery capacity of 4,883 mAh for its iPhone Duo in an EU energy label. The figure puts its capacity above the eSIM-only iPhone 18 Pro but below the eSIM-only iPhone 18 Pro Max, based on iFixit's findings for those models.
The label appears to corroborate an earlier leak that listed two cells, with capacities of 2,962 mAh and 1,921 mAh. Their combined capacity was reported as 4,883 mAh.
That figure is expected to apply worldwide because the Duo supports only eSIMs. There is no physical SIM tray version with a slightly smaller battery. For the other models, iFixit found capacities of 4,288 mAh for the eSIM-only iPhone 18 Pro and 5,567 mAh for the equivalent Pro Max.
