Battery capacities for Apple’s entire iPhone 17 lineup have reportedly surfaced in a Chinese regulatory database, offering the clearest look yet at what to expect from the iPhone 17, iPhone 17 Air, iPhone 17 Pro, and iPhone 17 Pro Max. The figures were circulated by the well-known leaker ShrimpApplePro on X and suggest minor variations tied to whether a given model includes a physical SIM tray or goes eSIM-only.
What the filing suggests
The database entries indicate Apple is preparing multiple battery configurations for certain iPhone 17 models, with eSIM-only variants carrying slightly higher capacities than versions that retain a physical SIM slot. The base iPhone 17, however, appears in just a single capacity so far, hinting at a unified global configuration for Apple’s most mainstream model.

Perhaps unsurprisingly, the ultra-thin iPhone 17 Air is flagged as the device most likely to skip a physical SIM tray in more markets. Space is the ultimate currency inside a thin chassis, and reclaiming the SIM module’s footprint can translate into a few extra milliamp-hours—or free up volume for thermal management and camera hardware.
As with any pre-launch filing, treat the specifics as provisional. Regulatory databases are a reliable early pulse check on hardware, but Apple’s final shipping mix can differ, and model-by-market availability often shifts late in the process.
Why the SIM tray matters for battery size
Even a small plastic-and-metal SIM assembly consumes precious internal volume. In past U.S. iPhone generations, Apple filled the SIM cavity with a placeholder after moving to eSIM, resulting in identical battery sizes across regions. This time, the records imply Apple may be taking advantage of that reclaimed space in certain markets to bump capacity by a sliver—consistent with the practical engineering trade-offs seen in other compact flagships.
Global eSIM support has expanded rapidly, with the GSMA counting hundreds of operators now offering eSIM provisioning across major regions. Still, local requirements and consumer expectations mean some countries—China is often cited by industry analysts—may continue to see physical SIM trays on select models, at least for another cycle.
mAh isn’t the whole story
Capacity leaks arrive in milliamp-hours, but watt-hours are the more apples-to-apples metric when voltage varies. In Apple’s case, iPhone batteries typically share similar voltages, making mAh comparisons broadly useful. That said, real-world battery life depends just as much on silicon efficiency, display technology, thermal headroom, and software scheduling as on raw capacity.
Expect Apple’s next A‑series chip, advanced LTPO displays on Pro models, and iOS-level power management to do as much heavy lifting as any capacity tweaks. Historically, Apple has maintained or improved stamina year over year even when battery sizes stayed flat, leaning on more efficient processors, adaptive refresh rates, and tighter background task orchestration.
What it means for the iPhone 17 lineup
The leaked matrix implies a balanced strategy: a unified capacity for the standard iPhone 17 to streamline supply, slight capacity offsets for SIM-equipped variants where needed, and a focus on design efficiency for the ultra-thin Air. Pro models appear to continue Apple’s trend of prioritizing sustained performance and endurance through a mix of modest battery growth and deeper platform optimizations.
If past patterns hold, Apple’s published battery life claims may show incremental improvements rather than dramatic leaps. Look for gains in intensive scenarios like high-brightness camera use, 5G data sessions, and sustained gaming—areas where thermal and power budgets matter most.
Official figures likely soon in the EU
Thanks to the European Union’s energy labeling framework for smartphones, manufacturers now provide standardized energy data on product pages and information sheets in EU markets. That means Apple’s official mAh figures should become public alongside the new lineup’s listings, providing a definitive cross-check against these leaked capacities.
Until then, the regulatory entries and corroborating supply chain chatter paint a coherent picture: small but meaningful capacity tuning across the iPhone 17 family, driven by regional SIM hardware choices and Apple’s continued push to extract more battery life through system-level efficiency rather than brute-force battery growth.
