Apple’s forthcoming iPhone 17 Pro Max is anticipated to feature a significantly larger battery,possibly reaching 4252 mAh,a significant increase from the iPhone 16 Pro’s 3582 mAh. This represents a 670 mAh jump in capacity compared to its predecessor.
The larger battery capacity across the iPhone 17 lineup-including expected 3692 mAh and 3149 mAh batteries for the standard iPhone 17 and iPhone 17 Air models, respectively-addresses growing consumer demand for extended battery life in power-intensive smartphones. Though, iPhone 17 variants sold in regions requiring a physical SIM card, such as India, may have slightly reduced battery sizes to accommodate the SIM slot. Apple is expected to release an e-SIM-only version of the iPhone 17 Air globally, potentially maintaining the rumored battery capacity despite the thinner design.
