Behind the scenes look at Apple's next big phonetic powerhouse: The iPhone 17 Pro Max, rumored to boast its largest battery yet, according to fresh leaks.
The upcoming iPhone 17 Pro Max is set to make a significant leap in battery life, with reliable leaks suggesting a potential battery capacity of approximately 5,000 mAh. This marks a 10% increase compared to the iPhone 16 Pro Max's 4,676 mAh.
The increased battery capacity is a result of several factors. One of the key reasons is the physical design changes. The iPhone 17 Pro Max is rumoured to have a slightly increased depth, allowing a larger dual-stacked battery to be fitted inside. This stacking technology permits a denser battery layout to increase capacity without drastically changing the phone’s footprint.
Another significant factor is the advancements in battery technology. The new battery may feature a metal cover designed for better heat dissipation in an ultra-thin L-shaped design, which could support higher capacity while managing thermal constraints.
The device will also incorporate the A19 Pro chip and a new Qualcomm Snapdragon X80 modem, enhancing performance and connectivity but also necessitating a larger battery to maintain or extend battery life. Additionally, features like potential reverse wireless charging to power other Apple devices and support for faster 25W wireless charging may require greater battery capacity to sustain usage without sacrificing longevity.
Apple has shown a consistent trend of incremental increases in battery capacity over recent iPhone generations. With the iPhone 17 Pro Max, this trend continues, aiming for over 35 hours of usage, surpassing the 33 hours supported by the 16 Pro Max.
In terms of heat management, the metal packaging for batteries in the iPhone 17 Pro Max will dissipate heat better, preventing throttled frame rate during heavy gaming. This, coupled with the Snapdragon X80 Modem's promise of power efficiency during cellular use, suggests that the iPhone 17 Pro Max could provide a smoother and longer gaming experience.
The iPhone 17 Pro Max, along with the iPhone 17 and iPhone 17 Air, is expected to be equipped with an A19 Pro chip, 12 GB of RAM, and 25-watt wireless charging. Leaked images suggest that iPhone 17 Pro Max models with a SIM card tray will have an L-shaped battery, while U.S. models will have a rectangular battery shape.
Apple is expected to unveil the iPhone 17 series on September 9th, 2025. While the potential 5000mAh battery of the iPhone 17 Pro Max suggests it could become the most durable iPhone yet, final specifications are yet to be confirmed. Users who prioritize battery life should stay tuned for updates on the iPhone 17 Pro Max.
The A19 Pro chip and new Qualcomm Snapdragon X80 modem, integrated into the iPhone 17 Pro Max, will enhance its performance and connectivity, but also necessitate a larger battery to maintain or extend battery life. Additionally, features like potential reverse wireless charging and support for faster 25W wireless charging may require greater battery capacity to sustain usability without compromising its longevity.
The iPhone 17 Pro Max is rumored to have a new battery featuring a metal cover designed for better heat dissipation, which, coupled with the Snapdragon X80 Modem's promise of power efficiency during cellular use, could provide a smoother and longer gaming experience.
