The standard iPhone 15 and iPhone 15 Plus models share many similarities with the iPhone 15 Pro and iPhone 15 Pro Max models, but there are still some features that are exclusive to the Pro models, which distinguishes them from the standard models. Some of the features mentioned below are exclusive to the iPhone 15 Pro and iPhone 15 Pro Max models, so you won't find them on any other iPhone model.
The old Ring and Silent key is still on the iPhone 15 and 15 Plus models, but it has been replaced with a new button on the iPhone 15 Pro models below. Action button name. By pressing once or long pressing, you get several functions that are programmed from the settings.
By long pressing you will feel tactile feedback and visual signals on the interactive island, and then the pre-assigned function will be performed.
The Actions button lets you quickly switch between ring and silent modes, but as we mentioned, it's also customizable, so you can use it as a shortcut to open the camera, turn on the flashlight, start voice memos, switch between focus modes, open Magnifier, and launch shortcuts and automatic tasks. Later this year, the action button will also support the Translate app.
Optical zoom up to 5x
In the iPhone 15 and 15 Plus, Apple has improved optical zoom capabilities. Instead of only 0.5x and 1x optical zoom like the iPhone 14 and 14 Plus, you will now get the option of telephoto zoom of up to 2x, and this is achieved by switching to the 48-megapixel ultra-wide camera and using a specific part of it, specifically the 12-megapixel central section. This allows for improved optical zoom capabilities.
To understand this further, in some smartphone cameras, especially those with high-resolution sensors, it is common to use part of the sensor for specific functions such as zooming in or out. In this case, the iPhone 15 and 15 Plus have an ultra-wide camera with a 48-megapixel sensor. However, for the 2x telephoto zoom, they only use the central 12MP portion of that sensor, a technique known as pixel binning or cropping.
The reason for this is that using the central part of the sensor can provide better image quality when zoomed in than using the entire sensor. By cropping or using this 12MP section, it allows for a sharper and sharper 2x optical zoom. This can result in sharper, more detailed images when zooming in on a subject.
While this is impressive, the iPhone 15 Pro Max's telephoto lens reaches 5x optical zoom, which represents a 67% increase over the maximum zoom of the iPhone 14 Pro and 14 Pro Max. But the bad thing is that the iPhone 15 Pro reaches a maximum of 3x optical zoom, like last year's Pro models.
The body on the iPhone 15 Pro and 15 Pro Max models is made of aerospace-grade titanium, making the devices lighter and stronger than the stainless steel found in last year's models. Apple claims it has “the highest strength-to-weight ratios of any metal.” This means that it is exceptionally strong for its weight, which is important for durability and reducing the overall weight of the phone.
The body has soft edges and thinner borders than any other iPhone screen. The inner frame of the chassis is made of 100% recycled aluminum to enhance strength and durability. This choice aligns with sustainability goals, also helps dissipate heat, and makes it easy to replace the back glass if necessary.
A17 Pro processor
Apple provided both the iPhone 15 and iPhone 15 Plus with the A16 Bionic processor, which is found in the iPhone 14 Pro models. Both the iPhone 15 Pro and iPhone 15 Pro Max are equipped with the completely new A17 Pro processor, which is a processor that comes with a manufacturing accuracy of 3 nanometers in the world, and this leads to improved performance and energy efficiency. The processor contains a six-core graphics processing unit that is up to 20% faster than the five-core A16 Bionic chip. This increase in GPU performance is important; Because it leads to smoother and more detailed graphics in applications, especially in games and augmented reality.
The A17 Pro chip comes with a significant improvement in how it deals with graphics technology called “ray tracing.” In the past, ray tracing was mostly done using software, which could require significant on-device computing effort, but the A17 Pro takes a different approach.
Instead of relying on software for ray tracing, the A17 Pro processor has specialized components built into the chip that can handle ray tracing tasks. These components are exceptionally fast and efficient, being four times faster than software-based ray tracing.
Ray tracing technology is important for creating highly realistic graphics. They help accurately simulate how light interacts with objects, resulting in realistic effects such as reflections, refractions (the bending of light as it passes through objects) and realistic shadows.
These ray tracing improvements are especially important in gaming and augmented reality applications, where realistic graphics are essential for creating immersive experiences. Therefore, the A17 Pro's hardware-level ray tracing aims to provide a much better visual experience in these types of applications.
In short, the A17 Pro's advancement in hardware-level ray tracing technology is significant as it significantly enhances the realism and visual quality in gaming and AR applications, making them more immersive and enjoyable for users.
Furthermore, the A17 Pro features an up to 10x faster CPU, a Neural Engine that runs up to 1x faster, and includes a dedicated AVXNUMX decoder, enhancing the efficiency and quality of video streaming experiences.
USB controller 3
All iPhone 15 models have moved from Lightning ports to USB-C ports. It is worth noting that the iPhone 15 Pro series features the A17 Pro chip, as we mentioned earlier, which includes a USB controller that supports USB 3 instead of USB 2 found in the iPhone 15 and 15 Plus models. This improvement results in significantly faster data transfers, reaching speeds of up to 10 Gbps, a significant improvement of up to 20 times over USB 2. Furthermore, it enables higher quality video output, with support for resolutions up to 4K at 60 fps with HDR.
