Apple usually reserves new high-end features exclusively for its premium Pro iPhones, yet this year’s base iPhone 15 and iPhone 15 Plus could somehow one-up the iPhone 15 Pro with a new technology, according to a new post by Ming-Chi Kuo.
In a new post on X, Kuo claims that the two base iPhone 15 models are set to be the world’s first smartphones to incorporate a stacked sensor on their main cameras. It is unclear why Apple opted to limit these features to the lower-end iPhone 15 models, but recent yield issues may have prompted Apple to limit the new sensors to the iPhone 15 and iPhone 15 Plus as some sort of a trial run, as these two phones are predicted to only account for 25% of all iPhone 15 unit shipments.
Kuo’s post today seemingly reiterates his previous prediction that the stacked camera design will be heading to the iPhone 16 Pro next year after resolving production yield issues. Exclusively assembled by Sony, the purported stacked sensor incorporates a configuration where the photodiode and transistor for each pixel are positioned in two distinct layers, with the former placed atop the latter. In contrast, conventional sensors combine both onto one layer, resulting in limited space for both the photodiode and the transistor.
The immediate effects of this stacked design are better light sensitivity and low light performance, allowing as much as twice the amount of light to be absorbed by the sensor compared to conventional cameras. Other improvements include superior dynamic range and lower image noise thanks to larger and separated pixel transistors.
With the iPhone 15 Pro and iPhone 15 Pro Max rumored to retain last year’s iPhone 14 Pro’s 48-megapixel camera based on a conventional non-stacked design, Apple could find itself in an awkward position where the base iPhone 15 might actually capture better photos than its $1000 a pop iPhone…
