The iPhone 17 series from Apple is merely a day away, but that doesn’t imply the speculation will cease.

The newest insights from leaker ShrimpApplePro (as reported by MacRumors) supposedly disclose the precise battery capacities for each of the upcoming iPhones, allegedly sourced from Chinese regulatory filings.

Apart from the actual capacities, another fascinating detail from the leak is the noticeably different capacities for iPhone variants with and without a SIM card slot (which occupies some internal space within the phone, consequently lessening the theoretically available space for the battery).

The details are as follows:

• iPhone 17 Pro: 3,988mAh with a SIM card slot, 4,252mAh without a SIM tray slot

• iPhone 17 Pro Max: 4,823mAh with a SIM card slot, 5,088mAh without a SIM tray slot

• iPhone 17 Air: 3,036mAh with a SIM card slot, 3,149mAh without a SIM tray slot

• iPhone 17: 3,692mAh (only one value is provided for this model, and it remains unclear whether that pertains to the model with or without the SIM card slot)

If this information is correct, the figures are notable, as they validate previous speculation that the iPhone 17 Pro Max will be the first iPhone ever to boast a battery exceeding 5,000mAh in capacity. Moreover, the battery of the iPhone 17 Air seems rather small, particularly in comparison to the iPhone 17’s battery. It will be interesting to see if Apple manages to compensate for this by incorporating its own C1 modem in the iPhone 17 Air, which is another rumor circulating about the forthcoming device.
