How many inches of screen Xiaomi Mi 8: specifications and comparison with analogues

The Xiaomi Mi 8 is one of the brightest flagships of 2018, and is still a hot choice for many users. When buying a used or refurbished device, the question often arises: how many inches does this model have? The answer seems simple, but the numbers hide important nuances, from aspect ratio to pixel density, which directly affect the comfort of use.

In this article, we will not only reveal the exact size of the Mi 8 display in inches and centimeters, but also compare it with competitors of the time (Samsung Galaxy). S9, iPhone X, OnePlus 6, let’s analyze the features AMOLED-And we're going to show you why this is important when you're looking at a smartphone, and if you're planning to buy it, or if you just want to understand how the 6.21-inch screen fits into the current standard, read on.

Official screen characteristics Xiaomi Mi 8

According to Xiaomi’s technical documentation, the Mi 8 is equipped with a display with a diagonal of 6.21 inches, which is specified by the manufacturer and confirmed by independent tests (for example, from GSMArena or NotebookCheck). However, it is important to understand that the actual “useful” screen area may vary slightly due to the rounded corners and notch for the front camera (the so-called “fracks”).

Key display parameters:

• 📏 Diagonal: 6.21 inches (15.77 cm)
• 🔳 Permission: 2248 × 1080 pixels (Full) HD+)
• 🎨 Type of matrix: Super AMOLED (Samsung Display)
• 🔄 Aspect ratio: 18.7:9
• 🔍 Pixel density (PPI): ~402

Interesting fact: the Mi 8 was Xiaomi’s first smartphone with a notch, which caused a mixed reaction from users. Some criticized the design for reducing the usable area, others praised the compactness of the case at a large diagonal. For comparison, the iPhone X of the same year had a screen of 5.8 inches, but due to the lack of frames occupied almost the same area as the Mi 8.

How to measure the screen diagonal yourself

If you already own the Xiaomi Mi 8 and want to make sure it meets the specifications, you can measure the diagonal manually. This will require a ruler or a rod (for greater accuracy).

Step-by-step:

1. Turn on your smartphone and go to the main screen (so that interface elements do not interfere).
2. Take a ruler with a millimeter scale and apply it from one corner of the screen to the opposite (diagonally).
3. Write down the value in centimeters. For example, if the diagonal was 15.7 cm, this corresponds to 6.2 inches (1 inch = 2.54 cm).
4. To check the accuracy, divide the centimeters by 2.54 – should be ~6.21.

Apply the ruler strictly diagonally |Use the millimeter scale |Do Not capture the frame of the case |Repeat measuring 2-3 times for accuracy-->

Note that in practice, because of the rounded corners and the cutout, the real "visible" diagonal can be 0.05 to 0.1 inches smaller than the declared diagonal. This is normal and not considered a marriage. If the difference is greater than 0.2 inches, it is worth checking the smartphone for authenticity - perhaps it is a fake with another screen.

Comparison with 2018 competitors: who won the inch race?

2018 was a watershed year for the smartphone market, with manufacturers actively increasing screen diagonals in an effort to create a “frameless” design. Let’s compare the Xiaomi Mi 8 with key competitors of the time.

From the table, it is clear that the Mi 8 was in the “golden middle”: its screen was larger than the iPhone X, but inferior to the resolution of the Galaxy. S9+. The pixel density (402) PPI) It provides excellent clarity of the image, and AMOLED-The matrix guaranteed deep blacks and high contrast. Interestingly, the OnePlus 6 had a slightly larger screen (6.28 inches), but the body of the device was almost identical in size due to more rational use of the front panel.

💡

When choosing between the Mi 8 and OnePlus 6, consider the screen-to-body ratio: OnePlus had ~83.8%, and Xiaomi had ~83.7%. The difference is minimal, but can be critical for those who like the most “frameless” design.

• 🎮 Fast response time: important for games and dynamic content (response time in Mi 8) ~1 ms vs. 5-10 ms y LCD).

However, AMOLED has drawbacks:

• 📉 pixel burnout: with prolonged display of static elements (for example, navigation panels), shadows are possible".
• 💰 Cost of repair: replacement AMOLED-The screen is more expensive than LCD.
• 🌈 Color shift when viewed from an angle: the Mi 8 has a minimal effect, but is noticeable in bright colors.

For comparison: flagships Xiaomi with LCD-The screens (e.g. Mi 8 Lite) had a diagonal of 6.26 inches, but were inferior in contrast and energy efficiency. Thus, the 6.21 inches in the Mi 8 is not just a size, but a combination of diagonal with advanced performance. AMOLED.

2. Screen flickering at low brightness

The problem manifests itself as a pulsation of the illumination (PWM-flickering at a brightness below 30 percent. AMOLED-It's more visible in the Mi 8 than Samsung's flagships:

• 🌓 Set the brightness not below 35-40%.
• 🔄 Enable adaptive brightness in settings (Settings) → Display. → Adaptive brightness).
• 🛠️ Use applications like this. DC Dimming (root rights required).

3. Scratches and microcracks

Despite the protection of the Gorilla Glass 5, the Mi 8 screen is vulnerable to scratches from metal objects (keys, coins). Xiaomi does not specify the exact hardness of the glass, but according to JerryRigEverything tests, it scratches at level 6 on the Mohs scale (like most flagships).
