Undoubtedly, the Xiaomi Mi 11 Ultra is one of the flagship smartphones available on the market, capable of delivering exceptional performance across various sectors. At first glance, you will immediately realize you are facing a powerful flagship smartphone. Its attractive and distinct design provides a unique visual appeal. On the front, you see a seamless and beautiful display equipped with an Infinity-O notch design. The circular notch at the top left corner houses the selfie camera sensor. The curved edges of the screen minimize the bezels, resulting in a screen-to-body ratio of 91.4%. The fingerprint sensor, a highly practical security feature, is located under the display. Based on conducted tests, this optical sensor provides rapid performance in unlocking the screen.

The iPhone 13 smartphone family was introduced in four models: iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 Mini. Without a doubt, the Pro and Pro Max models, as the company's flagships, utilize more powerful technical specifications. Meanwhile, the iPhone 13 and the Mini model have been released at a more affordable price to make them accessible to a wider range of users. In this article, we will examine the specifications of the iPhone 13 compared to the previous generation and evaluate its performance in different areas. Given the similar specifications between the iPhone 13 and iPhone 12, you might wonder why the iPhone 13 delivers better performance. Stay with us as we explore the reasons for the superior and more powerful performance of the iPhone 13 compared to the iPhone 12.

Attractive Design

Apple is generally reluctant to change its successful designs and prefers to maintain its iconic design language. The iPhone 13 follows a similar design to its predecessor. On the front, we see the familiar notch, which is now narrower compared to the iPhone 12 notch. On the rear, we see two camera sensors which, unlike the iPhone 12, are now arranged diagonally along with an LED flash within a square cutout. In contrast, the two camera sensors on the back of the iPhone 12 were arranged vertically.

In this section, it should be noted that the iPhone 13 utilizes a display similar to the iPhone 12. A 6.1-inch OLED display with a resolution of 1170x2532 pixels, featuring Super Retina XDR technology, has been chosen for this powerful smartphone. A pixel density of 460ppi ensures that this display provides high image quality. The Scratch-resistant ceramic glass screen protector effectively shields the display from impacts and accidental drops.
As we know, the displays of the iPhone 13 Pro and 13 Pro Max are capable of providing a 120Hz refresh rate. This is the first time in the history of Apple smartphones that we see such a screen. However, the iPhone 13 and iPhone 13 Mini, like previous generations, offer a 60Hz refresh rate. In terms of brightness, this display can reach a peak brightness of 1200 nits. Such brightness levels ensure high clarity and image quality for the iPhone 13 screen even under diverse lighting conditions and direct sunlight.

Camera

At first glance and on paper, the camera sensors utilized in the iPhone 13 might not seem significantly different from those of the iPhone 12; however, the iPhone 13 undoubtedly delivers superior performance compared to its predecessor. You may wonder why. We will explore the reasons below. First, let's review the technical specifications of this smartphone's camera sensors. The dual camera system of the iPhone 13 consists of a 12-megapixel main wide sensor with an f/1.6 aperture and a 26mm focal length, accompanied by a 12-megapixel ultra-wide sensor with an f/2.4 aperture, a 120-degree field of view, and a 13mm focal length. For the selfie camera, a 12-megapixel wide sensor with an f/2.2 aperture is featured, which is capable of recording 4K video at 60 frames per second. But why does the iPhone 13 provide higher quality image output despite using camera sensors similar to the iPhone 12? The primary reason for this improvement is the more powerful processor integrated into the iPhone 13.

This is Xiaomi's ultimate flagship in Iran.
It provides excellent, seamless, and professional support for the Persian language.
What type of adapter should I purchase for this phone to ensure optimal performance?
The specifications mention wireless charging support; will it also charge with car wireless chargers?
The Global ROM is pre-installed, and it supports the Persian language and Google Play services.

One of the primary reasons for better image output is the Image Signal Processor (ISP), which is a component of the processor. Consequently, utilizing a more powerful processor results in higher-quality image outputs. The performance of the 12-megapixel main camera sensor in daylight is beyond reproach. Impressive dynamic range, excellent detail, and striking contrast are clearly visible in the captured images. The wide aperture also allows for excellent light absorption, indicating this smartphone's superior performance in night photography or low-light conditions. The ultra-wide camera sensor, with a broader field of view compared to the main sensor, enables you to capture stunning wide-angle shots (ideal for nature photography and group photos).

However, Apple flagships have always had a lot to offer in the field of video recording, and to date, none of the company's Android competitors have been able to surpass Apple's flagship performance in cinematography. The main camera sensor of this smartphone is capable of recording video at a maximum quality of 4K at 60 frames per second. This camera sensor is equipped with the highly impressive OIS (Optical Image Stabilization) feature—a capability that effectively eliminates unwanted shakes during video recording, resulting in high-quality video output. Like the previous generation, this phone's camera sensor is capable of recording Cinematic video, which represents the highest possible video recording quality among all global flagships. However, this time Apple has introduced significant improvements to the video department of this smartphone to easily satisfy the needs of a professional videographer. The camera's remarkable autofocus, powered by Artificial Intelligence (AI), demonstrates unparalleled performance. The automatic focus transition between subjects (for example, if two people are in the frame and the focus is on the person in front, as soon as the first person turns their head to look at the next person, the camera automatically focuses on the second person) is one of the new and compelling features of this powerful smartphone.

Unrivaled Processor and a More Powerful Battery

It must be acknowledged that to date, Apple's powerful smartphone processors, combined with the exceptional iOS operating system, have delivered astonishing performance. Once again, the iPhone 13, like its larger siblings—the iPhone 13 Pro and iPhone 13 Pro Max—is equipped with the company's most powerful processor, the A15 Bionic. This processor features a 5nm architecture and consists of 6 cores (2 high-performance cores and 4 high-efficiency cores for lower energy consumption). For the GPU (Graphics Processing Unit), a dedicated 4-core processor has been utilized.
Based on benchmark results and conducted tests, it is safe to say that there is no game in the world that the iPhone 13, with such a powerful processor, cannot handle. It is worth noting that this phone can run demanding games such as Call of Duty Mobile and Asphalt 9 at the highest graphical settings. Furthermore, the 5nm architecture of this processor ensures lower energy consumption compared to 7nm and 10nm architectures, ultimately providing a longer battery life per 100% charge.
The iPhone 13 has been released in three models with internal storage capacities of 128GB, 256GB, and 512GB. Compared to the iPhone 12, we no longer see a 64GB option; instead, the iPhone 13 is available with 512GB of internal storage (a capacity that was not offered for the iPhone 12). Regarding battery capacity, as with every year, Apple has not officially disclosed the exact mAh rating for this smartphone. However, according to Apple, the iPhone 13 offers better battery life per full charge compared to the iPhone 12. The presence of the 5nm architecture and the advanced technology of this processor compared to the A14 Bionic results in significantly lower energy consumption.
