Liputan6.com, Jakarta - The iPhone 18 Pro Max has become a hot topic among gadget enthusiasts following rumors of improved camera and battery quality.

Rumors about the iPhone 18 Pro Max have been hotly debated, particularly regarding significant improvements to the camera and battery, which are touted as revolutionary.

While still speculative and without official confirmation from Apple, these leaks offer an interesting glimpse into the innovations this premium device might bring.

Based on previous launch patterns, the iPhone 18 Pro Max is predicted to be introduced around September 2026.

The Pro and Pro Max models are rumored to be released first, while the standard iPhone 18 variant is likely to follow in 2027, a strategy likely aimed at managing the supply chain and expanding Apple's product portfolio.

iPhone 18 Pro Max Battery Capacity Rumors

One of the most intriguing aspects of the iPhone 18 Pro Max is the rumored significantly increased battery capacity.

The device is rumored to have a battery capacity above 5,000mAh, with some reports suggesting prototypes have a capacity of around 5,100-5,200mAh.

Even bolder speculation suggests a capacity of up to 6,000mAh, potentially providing up to two full days of battery life.

For comparison, the iPhone 17 Pro Max, its predecessor, has a 5,088mAh battery, making it the largest iPhone battery to date, with an estimated battery life of up to 39 hours.

The international variant of the iPhone 18 Pro Max will likely come with a maximum capacity of around 5,100-5,200mAh, while the Chinese version is expected to have around 5,000mAh.

Superior Battery Efficiency and Life

The improved battery life on the iPhone 18 Pro Max comes not only from a larger capacity, but also from improved chip efficiency.

With the combination of a larger battery and a more efficient chip, battery life is expected to comfortably exceed 40 hours based on Apple's "video playback" estimates.

Improved power efficiency will also come from the upcoming A20 Pro chip, manufactured on TSMC's 2nm process.

This chip is claimed to be 20% faster and 30% more efficient than the A19 chip.

 

iPhone 18 Pro Max Camera Innovations

The iPhone 18 Pro Max's camera is also rumored to see a major breakthrough with the introduction of a variable aperture lens.

This technology will provide photographers with better depth of field control, allowing them to narrow the depth of field and provide greater control over the look of their photos.

A variable aperture can produce brighter photos with less noise in low-light conditions, as well as more natural background bokeh without the need for Portrait mode.

Analyst Ming-Chi-Kuo first reported on a variable aperture for the iPhone 18 Pro in late 2024, and Weibo leaker Digital Chat Station has confirmed that Apple is testing a variable aperture main camera and a large aperture telephoto lens.

It's unclear whether this feature will be available on both Pro models or only the Pro Max.

Furthermore, some rumors indicate the iPhone 18 Pro Max will feature a quad-camera module design, marking a significant upgrade from the triple-camera configuration that has been a hallmark of Apple's premium lineup for years.

The main camera is expected to have a resolution of 48 megapixels, while an improved telephoto lens with a "large aperture" is also rumored, which could improve telephoto performance in low light and produce a shallower depth of field.

The front camera is rumored to have a resolution of 24 megapixels, promising sharper and more detailed selfies.

In fact, some inconsistent rumors mention a quad-camera system with a 200MP main sensor, as well as 8K video recording capabilities at 60fps.
