Apple has slowly been finding ways to increase the battery size on its largest and most premium models, with the iPhone 15 Pro Max and iPhone 16 Pro Max sporting a small capacity difference that leads to better runtime on the newer version. However, if you noticed, both flagships feature the same thickness, which is 8.3mm, and that might be the physical limit for the company as a rumor claims that the iPhone 17 Pro Max will be slightly thicker than its predecessors. There are several reasons why a manufacturer would pursue changing the dimensions, and more often than not, it has to do with increasing the battery size.
Latest rumor does not confirm if Apple will incorporate silicon-carbon battery technology on the iPhone 17 Pro Max, which would not require an increase in the thickness
On X, notable tipster Ice Universe has pointed out that the iPhone 17 Pro Max will boast a thickness of 8.725mm, making it a 5 percent increase compared to the iPhone 16 Pro Max. He shares evidence of the upcoming flagship’s dimensions with an image that only mentions the aforementioned figure and nothing else, so there is much to learn about this handset before we jump to conclusions. As expected, we do not know if Apple will resort to using silicon-carbon batteries, which is a component that Chinese OEMs have embraced with open arms to increase the capacity size without compromising on the thickness.
However, we have reported that the Cupertino firm has been working to bring this technology to its devices, but no concrete launch time was mentioned. According to analyst Ming-Chi Kuo, the iPhone 17 Air will rely on high-density batteries, but that is no confirmation if the transition to silicon-carbon cells will happen later this year. We feel confident that the iPhone 17 Pro Max’s supposed thickness increase is for this very reason, and it could be due to the competition launching smartphones that exceed capacities of 6,000mAh.

It is not surprising to learn about these dimensions, especially when Apple and Samsung are companies that are known in the industry to jumpstart the development of their newer devices months in advance to be better prepared to make any adjustments. Then again, Ice Universe has been incorrect in the past, so remember to treat this information with a pinch of salt, and we will be back with more updates.
