Now is still ten months away from the unveiling of the iPhone 15 series, but rumors about the iPhone 15 series are one after another. Among these rumors, we understand that the iPhone 15: appearance, performance, and camera may change drastically.

First of all, start with the appearance. The appearance of the iPhone phone has been repeated between the arc border and the right-angle border, repeating over and over again. From the right-angle border of the iPhone 4 model to the arc border of the iPhone 6 model, and then to the iPhone 12, the iPhone phone returned to the original right-angle border and continued to the latest model of the current iPhone 14 series.
It is said that in order to compare with iPhone 14, Xiaomi 13 will also adopt a right-angle border design. But for the iPhone 15 series, according to the renderings currently leaked, the back edge of the iPhone 15 series has curves, and the side will use solid-state buttons to replace the physical volume buttons. The appearance design of

not only retains the tough style of square lines, but also provides a more comfortable grip.
It is worth mentioning that in terms of body material, the iPhone 15 series will make an exception to use titanium metal. The back and sides of the entire phone will use an integrated titanium metal body, which will be full of texture and toughness, and the body is also lighter.
In terms of performance, the current iPhone 14 series has differentiated chips for the first time. The standard model allocates the previous generation of Apple A15 chips, while the Pro model uses the latest Apple A16 chips. In terms of core performance, the iPhone 15 series may continue the differentiated distinction of the previous generation. The standard iPhone 15 will be equipped with the current 4nm Apple A16 chip, and the iPhone 15 Pro series will use the most advanced 3nm Apple A17 chip.

TSMC 4nm chips are already very advanced. The newly released Snapdragon 8Gen2 and Dimensity 9200 use the second generation of TSMC 4nm process technology , which has greatly improved performance, energy efficiency and functions. If the iPhone 15 Pro is equipped with a 3nm chip, its performance level will be ahead of the world. How lonely it is to be invincible!
In terms of cameras, according to a new report, Sony has developed a new camera sensor that will use a new semiconductor architecture to separate photodiode and pixel transistors on different layers instead of putting them on the same substrate.
, a camera sensor, will be used in the iPhone 15 Pro series. It is said that the pixels of the camera will not be improved, but the performance of the camera is expected to be significantly improved.
Sony claims that this is the most advanced image sensor that doubles the saturated signal level. This means it will have twice as much light-concentrating capabilities as the current sensor, which will help minimize overexposure and underexposed under certain lighting conditions. With the iPhone 15 Pro, you can take clear photos even under strong backlight. The most important thing about

is that compared with the one-inch camera sensors of flagship phones such as Xiaomi and vivo, the new camera sensor of iPhone 15 Pro has more advantages. The highest-end models, which might be called the iPhone 15 Ultra, rather than the iPhone 15 Pro Max, are also highly likely to be equipped with a periscope zoom unit for better optical zoom .
Judging from the above rumors, for those who pursue the ultimate experience, you can look forward to the iPhone 15 Pro and Ultra models, but for friends who pay attention to cost-effectiveness, I think the current iPhone 14 is still a good choice.
