With Apple’s official iPhone 17 unveiling just around the corner, fresh details have surfaced regarding the battery configurations of the upcoming lineup. The information originates from the Chinese 3C certification database and was brought to light by reliable tipster ShrimpApplePro on X. Although the listings are yet to be independently confirmed, they provide an early glimpse into how Apple is shaping the power capabilities of its 2025 smartphones.
According to the certification data, the iPhone 17 Air, iPhone 17 Pro, and iPhone 17 Pro Max will come in two versions—one with a physical SIM slot and another with eSIM-only support, depending on regional markets. Curiously, only a single entry appears for the standard iPhone 17, leaving some uncertainty about whether it applies to the SIM-enabled or eSIM-only model.
The reported capacities are as follows:
If these figures hold true, the iPhone 17 Pro Max will be the first iPhone ever to cross the 5,000mAh mark, delivering nearly an 8% boost in capacity compared to the iPhone 16 Pro Max. This increase could translate into noticeable improvements in screen-on time and all-day endurance, especially for power users.
While the Pro Max stands out for its record-breaking battery size, the iPhone 17 Air is set to carry the smallest cell in the family. This design decision matches its ultra-slim profile. To balance its reduced capacity, Apple is expected to rely on the new C1 modem, designed to enhance power efficiency. Reports also suggest the company may introduce a dedicated battery case to complement the Air model, catering to users who demand longer runtimes.
Apple has traditionally focused on efficiency gains rather than massive jumps in battery size, but the iPhone 17 lineup shows a more aggressive push toward larger capacities—particularly in the Pro series. The move could give Apple a stronger edge against Android competitors, many of which already ship with batteries exceeding 5,000mAh.
With official announcements just days away, Apple fans won’t have to wait long to see how these numbers translate into real-world performance. Alongside the battery upgrades, the iPhone 17 series is also expected to bring display improvements, a new chipset, upgraded RAM, and expanded storage options.
