Fresh leaks about the iPhone 17 battery have surfaced online, hinting at some of the biggest changes Apple has made in years. A newly spotted regulatory database entry suggests that Apple’s upcoming iPhone 17 lineup will feature slightly different battery capacities depending on whether the device includes a physical SIM card slot or goes fully eSIM.
iPhone 17 Battery Specifications (Alleged)
According to the leak, the iPhone 17 Pro Max battery could be Apple’s first to cross the 5,000 mAh mark, with the eSIM-only variant boasting a powerful 5,088 mAh cell. Here’s what the reported figures show:
- iPhone 17 – 3,692 mAh (SIM tray model)
- iPhone 17 Air – 3,036 mAh (SIM) / 3,149 mAh (eSIM)
- iPhone 17 Pro – 3,988 mAh (SIM) / 4,252 mAh (eSIM)
- iPhone 17 Pro Max – 4,823 mAh (SIM) / 5,088 mAh (eSIM)
Regional Differences in iPhone 17 Battery Models
Apple is expected to keep offering both SIM tray and eSIM-only versions, depending on the country. U.S. customers will continue to see eSIM-only models, while markets such as China may still require physical SIM support due to regulations. The iPhone 17 Air battery is notably smaller, but its ultra-thin design makes it more likely to launch in multiple regions without a SIM slot.
Energy Efficiency and Possible Accessories
Even though the iPhone 17 Air comes with a smaller power cell, Apple is reportedly compensating with its highly efficient C1 modem. This could help extend performance without draining the battery too quickly. Additionally, rumors suggest a new official battery case might debut alongside the iPhone 17 Air to further boost its runtime.
