The next release of the iPhone 17 Pro Max continues to generate excitement among the brand's followers and regular users, especially due to the new features that revolve around its autonomyThe most recent leaks point to a significant increase in battery capacity, an aspect that could place the Pro Max model at the top of the iPhone ecosystem and among premium-range phones in general.
A considerable leap forward compared to previous generations
According to various reputable sources in the technology sector, such as the leaker Instant Digital in Weibo, Apple is betting on a change of direction this year: Let go of the obsession with extreme thinness and prioritize battery lifeThe iPhone 17 Pro Max is said to feature a battery of around 5.000mAh, a figure previously unseen in the company's smartphones.
The battery growth compared to other years is notable: the iPhone 14 Pro Max was around 4.323 mAh, the 15 Pro Max went up to 4.422 mAh, and the current iPhone 16 Pro Max has already reached 4.676 mAh. If the forecasts are confirmed, the model that will arrive in September would improve by around 7-10% compared to the previous one, a significant increase in a sector where every milliamp-hour counts.
| Córdoba | Battery |
|---|---|
| iPhone 11 Pro Max | 3,969 mAh |
| iPhone 12 Pro Max | 3,687 mAh |
| iPhone 13 Pro Max | 4,352 mAh |
| iPhone 14 Pro Max | 4,323 mAh |
| iPhone 15 Pro Max | 4,422 mAh |
| iPhone 16 Pro Max | 4,676 mAh |
| iPhone 17 Pro Max | ~5,000 mAh |
To accommodate this larger battery, the device will be somewhat thicker, increasing its thickness from 8,25 mm to approximately 8,725 mm. While the change isn't radical, Apple seems willing to stop sacrificing battery life in favor of an ultra-thin design, thus addressing one of the most common user requests.

Impact on autonomy and efficiency
A bigger battery does not automatically translate into more hours of use, as other factors such as processor efficiency or software optimizations are also key. This year, Apple will add the new A19 Pro chip, which along with the Snapdragon X80 modem and the new features of iOS 26, such as the Adaptive Power feature, should further improve actual runtime.
Currently, the iPhone 16 Pro Max offers approximately 33 hours of battery life for video playback. Estimates suggest the new Pro Max could reach or even exceed 35 hours, approaching the benchmarks of rivals like the Galaxy S25 Ultra. This would position it as the benchmark for battery life in high-end smartphones.
Changes only in the Pro Max?
Leaks indicate that the battery boost will be exclusive to the Pro Max model., while the iPhone 17 Pro is said to retain its current dimensions. Thus, the difference between the two would not only be in the screen size or the camera, but also in the battery life, underscoring the focus on segmenting the range more clearly.
Apple's new approach responds to the demands of users seeking a genuine improvement in everyday use. Additionally, rumors suggest the integration of new battery technologies and a vapor chamber cooling system to improve overall performance.
Users who prioritize autonomy will find the iPhone 17 Pro Max an ally for long days. and intensive uses, whether for work, travel, or simply not having to worry about finding a charger in the middle of the afternoon. The slight increase in weight and thickness seems a reasonable trade-off if it translates into several additional hours of use.
Apple's strategic shift in the iPhone 17 Pro Max is betting on the largest battery in its history Along with hardware and software optimizations, if the rumors are correct, this model could become the benchmark for battery life among premium smartphones, putting an end to the debate about iPhone battery life.
