For iPhone fans, here are the latest leaks regarding the iPhone 17 Pro Max, its innovative design, and the specifications of its new, larger-capacity battery, unprecedented in previous models. Other features will also be revealed, including a host of other features that will please the vast audience eagerly awaiting the launch of the new phone.
Expected new features in the iPhone 17 Pro Max:
According to rumors, the iPhone 17 Pro Max will feature a 5,000 mAh battery, the largest in iPhone history, compared to the 4,676 mAh battery in the iPhone 16 Pro Max, an increase of approximately 6.9%. This update reflects Apple’s efforts to improve battery life, with the phone expected to provide approximately 35 hours of use, compared to 33 hours in the previous model.
In addition, the expected radical changes include:
- A thicker design (8.725 mm vs. 8.25 mm) to accommodate the new, larger battery size and capacity.
- Changes to the camera design, with a rectangular aluminum bump and wider lenses.
- A new color called “Sky Blue.”
- An animated Apple logo on the back, with exterior design improvements. A 3nm A19 Pro processor for improved performance and efficiency.
- 12GB of RAM for improved multitasking and AI features.
- The iPhone 17 Air is an ultra-thin phone, replacing the Plus model.
When will the iPhone 17 Pro Max be announced?
The iPhone 17 series is expected to be officially announced in September 2025, with design and technical changes aimed at improving the user experience. However, these leaks remain unconfirmed until the official launch.
Comparison between the iPhone 17 Pro Max 2025 battery capacity and previous models:
The iPhone 16 Pro Max has a 4,676 mAh battery.
The iPhone 15 Pro Max has a 4,422 mAh battery capacity.
The new iPhone 17 Pro Max surpasses all previous models with a battery capacity of nearly 5,000 mAh, an increase of nearly 10% over the current generation.
Is battery life enough to judge the new iPhone 17 Pro Max?
Despite the impressive battery life of the new iPhone 17 Pro Max, the final verdict on its novelty and suitability for users’ needs will depend on the user experience.
However, this isn’t the only criterion for judging the new phone. There are many other criteria, such as iOS 26 improvements, heat management, processing efficiency, and screen refresh rates.
New iPhone Battery Technologies
Apple has developed a new battery charging system for iPhones in iOS 26, aimed at extending battery life through smarter power management.
These improvements are expected to impact all Apple devices, but the system is specifically designed for the new iPhone 17 Air, which is expected to feature a smaller battery.
This development has also been vital for several other models, such as Apple’s foldable phone—known as the iPhone Fold—which faced battery challenges due to its need for a thinner frame to fold successfully.
It’s worth noting that Apple is redesigning the foldable display to improve battery performance.
Battery Technologies
The iPhone 17 Air (also rumored to be called the iPhone 17 Slim) is expected to use next-generation silicon anode battery technology developed by Japanese company TDK.
This innovation is said to offer up to 15% more power than current designs.
This energy-efficient technology is now available for mass production and is likely exclusive to the iPhone 17 Air for now. If it achieves the desired success, the iPhone 18 Pro Max could be released in 2026 with the same efficient power-saving technology.
The Pro Max model typically has longer battery life than the smaller Pro model, but this year, that gap could widen even further.
What does longer battery life mean?
It means more freedom to use your new phone. For example, the current iPhone 16 Pro Max battery performance, as published by Apple, includes up to 33 hours of video playback, 29 hours of live streaming, and 105 hours of audio playback.
The iPhone 17 Pro Max is expected to exceed these benchmarks.
The New iPhone Lineup
Apple has always offered a wide range of iPhone models with each release to suit all tastes and needs.
Apple is expected to launch the iPhone 17 lineup in September 2025, the usual annual launch date for new iPhones.
The expected models are:
- iPhone 17
- iPhone 17 Pro
- iPhone 17 Pro Max
- iPhone 17 Air, which is rumored to replace the Plus model with a slimmer design.
The most prominent event for iPhone fans:
Apple usually announces its new releases at a special launch event held at its headquarters in Cupertino, California.
This event usually takes place in the second week of September and is broadcast live worldwide.
Apple does not announce these releases at public trade shows like the Consumer Electronics Show (CES) or MWC, but rather at a special event held by Apple.
New iPhones and the Endless Race for Efficiency and Improvement
As September 2025 approaches, speculation and excitement are growing about the next generation of iPhones.
The iPhone 17 series promise more than just regular updates, but rather a quantum leap in performance, battery life, and user experience.
Rumors are dominating the news about the iPhone 17 Pro Max, which will feature a much larger battery, possibly as large as 5,000 mAh, promising significant improvements in the device’s ability to last all day.
The focus won’t be limited to the flagship models; the series will see an interesting addition with the arrival of the iPhone 17 Air (or iPhone 17 Slim), rumored to feature an ultra-thin design and new TDK silicon anode battery technology, promising unprecedented power efficiency.
These developments, coupled with iOS 26’s improvements in power management and thermal control, indicate that Apple is striving to deliver a comprehensive experience that goes beyond technical specifications.
It remains to be seen how these rumors and expectations will materialize into actual devices when Apple unveils them at its highly anticipated annual event.
September 2025 will undoubtedly be a significant date for tech enthusiasts, as we witness how Apple will redefine the smartphone experience once again.
