The iPhone 17 Pro Max will get the most powerful battery in Apple’s history

Apple will release four new iPhone models this fall, including the ultra-thin iPhone 17 Air. However, the flagship iPhone 17 Pro Max will go in the diametrically opposite direction – and in doing so, fulfill a longtime dream of many users: maximum battery life without compromise.
In 2024, Apple is betting on two opposing concepts at once. While one of them – the ultra-light and thin iPhone 17 Air – is focused on aesthetics and minimalism, the other – the iPhone 17 Pro Max – is centered on endurance and practicality. And the main draw of this model is its unprecedented battery capacity.
Apple will increase thickness for a bigger battery
If rumors are confirmed, the iPhone 17 Pro Max will be a little thicker than its predecessors – and solely for the sake of packing an even bigger battery inside. It’s not just to improve battery life, but to surpass all previous models and finally fulfill a need that users have been talking about for years: we want an iPhone that lasts longer.
Compare for yourself: the iPhone 15 Pro Max officially delivered up to 29 hours of video playback. The iPhone 16 Pro Max, thanks to its larger body, raised that bar to 33 hours. The new iPhone 17 Pro Max promises to go a step further – and reach a new level of battery life.

Inspiration from Apple Watch Ultra and user demand
Apple seems to have been inspired by the success of the Apple Watch Ultra, which gained popularity due to its high reliability and long battery life. The iPhone lineup is now adopting a similar philosophy.
While there’s no official confirmation yet, analysts are already circulating speculation that the iPhone 17 Pro Max may be renamed the iPhone 17 Ultra to emphasize its outstanding performance, especially in terms of battery life.
One iPhone, Two Approaches
Apple’s focus is on contrast: the lightweight and refined iPhone 17 Air for minimalists, and the massive and powerful iPhone 17 Pro Max for those who value endurance. In this way, the company is aiming to reach both audiences: those who want convenience and compactness, and those who want maximum performance and battery life.
