A recent leak indicates that the iPhone 17 Pro Max could feature Apple’s largest battery to date. The reported capacity is around 5,000mAh, which would surpass the 4,676mAh battery of the iPhone 16 Pro Max. This upgrade aligns with earlier speculation that the device will be slightly thicker than its predecessor.
Although the increase in thickness appears minimal approximately 0.475mm it could provide the necessary space to house a larger battery. This design change may lead to longer battery life, especially when paired with software and chip efficiency improvements.
Each iPhone release typically introduces new hardware and features, which often impact power usage. However, enhanced efficiency and hardware optimization may help mitigate battery drain, ensuring better overall performance.
Expected Battery Life Improvements
If the final battery size approaches the leaked figure, users could see a significant gain in screen-on time. Battery life has steadily improved with each iPhone generation. For instance, recent models have achieved battery life increases of 4–5 hours over their predecessors.
Although battery capacity doesn’t directly translate to longer life due to various system demands, a larger cell almost always provides better endurance. With a capacity approaching 5,000mAh, the iPhone 17 Pro Max may exceed the 33-hour battery life of the current model and possibly reach 35 hours or more.
This potential bump in performance would make a meaningful difference to users who depend on all-day usage without frequent charging.
Other Design Changes and Features
The Pro Max model may be roughly 5% thicker than the previous version, a move that could prioritize internal component upgrades. A larger battery is likely the main focus, though other additions like thermal improvements or structural changes could also contribute.
Camera features are also expected to improve. Both iPhone 17 Pro models are rumored to share a triple 48MP rear camera setup and a 24MP front camera. While earlier leaks mentioned changes to the Dynamic Island design, recent information suggests Apple may retain its current approach.
Overall, the iPhone 17 Pro Max appears poised to offer notable improvements in battery capacity and possibly overall battery life. While the design may not change dramatically, even minor physical enhancements could result in meaningful real-world benefits for users.
