iPhone 17 Pro Max Leaks Hints at the Biggest Battery yet and 35+ Hours of Power! 

iPhone 17 Pro Max is expected to be a powerhouse when it comes to battery longevity. Recent leaks suggest it may feature the largest battery ever seen in an iPhone, with a capacity of around 5,000 mAh. In comparison, its predecessor, the iPhone 16 Pro Max, has a 4,676 mAh battery. If these rumors are accurate, the iPhone 17 Pro Max could provide over 35 hours of battery life, setting a new record for flagship smartphones.

Why is this upgrade necessary? Along with its large battery, iPhone 17 Pro Max will feature an A19 Pro chip and a Snapdragon X80 modem. This suggests that Apple is prioritizing improvements in performance and connectivity, as well as power efficiency, ensuring users can maximize battery life with each charge. Here’s what we know so far.

The Battery Capacity: What We Know

For some time, reliable leaker Instant Digital has been posting on Weibo that iPhone 17 Pro Max will have a battery life of 5,000 mAh, which is a 10% increase compared to the previous generation. From leaked data, it seems true that Apple has a history of consistent battery growth, as seen below:  

  • iPhone 16 Pro Max: 4,676 mAh
  • iPhone 15 Pro Max: 4,422 mAh
  • iPhone 14 Pro Max: 4,323 mAh  

If indeed this upgrade is true, it correlates with current speculation around device body increases. Specifically, the increase in thickness from 8.25 mm to 8.725 mm provides enough space for a larger battery cell. 

Key Upgrades for iPhone 17 Pro Max Battery Life 

Simply, a larger battery isn't enough for longer battery life. Apple is expected to take advantage of:  

  • A19 Pro Chip: built on TSMC's 3nm process and will provide better performance-per-watt.  
  • Snapdragon X80 Modem: Qualcomm's latest modem will help conserve battery life during cellular use.  
  • Battery Housing from Metal: Metal packaging for batteries will dissipate heat better. So, there will be no throttled frame rate during heavy gaming.

With a bigger battery and the efficiency improvements, we could potentially see the iPhone 17 Pro Max get 35+ hours of battery life compared to 33 hours with the previous iPhone 16 Pro Max.

Design Trade-Offs: Thicker Body Meets Better Cooling

To take advantage of the larger capacity battery, iPhone 17 Pro Max may, if the leaks are accurate, be lighter and manage heatsinks more effectively. It is expected to include a vapor chamber cooling system, which would be a first for iPhones and help sustain higher performance. Leaked images of the battery diagram suggest that models equipped with a SIM card tray will feature an L-shaped battery, while U.S. models are expected to have a rectangular battery shape. 

When Will iPhone 17 be Released? 

Apple is expected to unveil the iPhone 17 series on September 9th, 2025, including the iPhone 17 Pro Max, as well as the iPhone 17 Air and the Pro variant, both equipped with an A19 Pro chip, 12 GB of RAM, and 25-watt wirelesscharging.

Is iPhone 17 Pro Max's battery Life Hype or Truth?

iPhone 17 Pro Max may feature a 5000mAh battery along with several impressive upgrades. It might become the most durable iPhone yet. While leaks indicate a potential launch in September 2025, we will have to wait for Apple's final specifications to determine whether this is true or simply hype. In the meantime, users who prioritize battery life should definitely stay tuned for updates in this area.
