The iPhone 17 series is said to include the standard iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone 17 Air, all expected to be unveiled on September 9.

Apple is preparing to introduce its much-anticipated iPhone 17 lineup at the global “Awe Dropping” launch event. Just days before its unveiling, a major leak has revealed the expected battery sizes of the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and the all-new iPhone 17 Air. Among the surprising revelations, the iPhone 17 Air could arrive with a 3,149mAh battery, which is larger than the earlier reported 3,000mAh unit. Meanwhile, the iPhone 17 Pro may launch in the US with a 4,300mAh battery, while a smaller 4,000mAh variant is expected for the Chinese market. The leak also highlights the battery details of the Pro Max version for both US and China.
The information originates from a post on X, where tipster Abhishek Yadav (@yabhishekhd) cited China’s CQC certification documents. According to his claim, the iPhone 17 Air will likely house a 3,149mAh unit, whereas the iPhone 17 Pro is expected with 4,300mAh in the US and 4,000mAh in China. In comparison, the iPhone 17 Pro Max may come with a massive 5,100mAh battery for the US version and a 4,900mAh unit in China.
Apple typically avoids disclosing the exact battery sizes of its smartphones during launch events, which keeps such leaks under high scrutiny. Earlier reports had suggested the iPhone 17 Air would feature a smaller battery, making this development particularly interesting for those concerned about longer usage time. The Pro Max variant has traditionally been Apple’s largest battery model, and this year appears to follow the same pattern. Previous leaks hinted at a 5,000mAh battery for the iPhone 17 Pro Max, though the new information suggests a slightly higher 5,100mAh capacity in the US.
Speculation also indicates that the larger battery of the iPhone 17 Pro Max may be a result of additional space inside the device, possibly enabled by the removal of the physical SIM tray in some regions. Reports suggest that Apple will expand dual eSIM-only models beyond the US, potentially reaching Europe. Countries like France, Germany, Italy, Spain, and the Netherlands are said to be part of this rollout.
Apple has already instructed retail staff of its authorised European resellers to complete training programs for handling iPhones without a SIM tray. The iPhone 14 series, which debuted in 2022, was the first to launch without a physical SIM tray in the US. With the iPhone 17 series expected to adopt this approach more widely, eSIM support is becoming a central focus. While this feature adds convenience, users who frequently swap SIM cards between devices might find the transition less seamless.
With the iPhone 17 Air, iPhone 17 Pro, and iPhone 17 Pro Max making headlines due to their leaked battery capacities, the excitement around Apple’s September 9 launch continues to grow. Whether these details prove accurate will be confirmed during the official event, but the leaked numbers have already intensified discussions among Apple enthusiasts worldwide.
