The reliability of sources claiming the existence of an iPhone 17 Ultra is based on recent rumors and analyses from reputable tech leakers and analysts. Here's a detailed breakdown:
1. Ryan Christoffel at 9to5Mac: Christoffel suggests that Apple might be preparing for an Ultra rebrand, possibly renaming the iPhone 17 Pro Max to iPhone 17 Ultra. This speculation is based on several rumors, including the iPhone 17 Pro Max being thicker than its predecessor, potentially accommodating a larger battery, and featuring a narrowed Dynamic Island and vapor cooling system[1][3]. These features could significantly differentiate the Pro Max from other models, aligning with Apple's strategy for the Apple Watch Ultra.
2. Ice Universe: Known for reliable leaks, Ice Universe has provided specific dimensions for the iPhone 17 Pro Max, stating it will be 8.725mm thick, compared to the iPhone 16 Pro Max's 8.25mm. This increase in thickness could allow for a larger battery, which is a key feature often associated with "Ultra" models[1][3].
3. General Rumor Landscape: The introduction of an iPhone 17 Ultra would align with Apple's trend of creating distinct "Ultra" models, as seen with the Apple Watch Ultra. This trend suggests that Apple might be exploring similar branding for iPhones to emphasize enhanced features and capabilities[3].
However, it's important to note that these are still rumors and speculations. Apple has not officially confirmed the existence of an iPhone 17 Ultra. The reliability of these sources is based on their past accuracy and the consistency of the rumors across different platforms.
In summary, while the sources are reputable and their speculations are intriguing, the existence of an iPhone 17 Ultra remains speculative until Apple makes an official announcement.
