As Apple prepares to begin deliveries of the iPhone Duo later this week, new official details have emerged about the device’s battery. Following the start of pre-orders, the company has released the EU energy label for its foldable iPhone, giving users a clearer look at both capacity and long-term performance expectations.
According to the published documentation, the iPhone Duo is equipped with a 4,883mAh lithium-ion battery that is divided into two cells. This confirms how Apple is distributing power inside its foldable design while maintaining a relatively slim form factor.
The energy label also states that the iPhone Duo achieves a rated endurance time of 51 hours and 30 minutes per charge cycle. In addition, Apple indicates that the battery is designed to maintain reliable performance through at least 1,000 charge cycles under default usage conditions.
Because the iPhone Duo is an eSIM-only device in all markets, its battery capacity is expected to remain consistent worldwide, with no regional differences in size or specifications.
