Many users are still interested in the technical parameters of the legendary Xiaomi Redmi 5 Plus smartphone, released in early 2018, which has long been considered a benchmark in the budget segment due to the successful combination of price and quality. One of the key questions when choosing or evaluating a device is the size of its display, since this parameter directly depends on the convenience of consumption of content.
In short, the screen is 5.99 inches. However, just knowing the inch number doesn't give you a complete idea of how the device feels in your hand or how to watch video on it. It's important to understand the aspect ratio, pixel density and type of matrix used to evaluate the actual user experience.
In this article, we will discuss in detail why this size was chosen by engineers, how it relates to modern standards and what advantages Full HD+ resolution gives compared to conventional HD.
Exact physical parameters of the display
The Redmi 5 Plus screen is 5.99 inches, which is about 15.21 centimeters diagonally across the visible area, and it was not a coincidence that the device was marketed as a “big phone” or even a mini tablet at the time of its release, allowing for comfortable document and multimedia processing.
The most important feature here is the 18:9 aspect ratio, which is more vertical than the old 16:9 standard, which has allowed Xiaomi to keep the physical width of the case comfortable for one-handed control, while significantly increasing the useful area for displaying information.
The resolution of the matrix is 2160 by 1080 pixels, which gives a pixel density of 403 ppi (pixel per inch). For the budget segment, this was a breakthrough indicator, providing high definition fonts and no “grain” when viewing images from close range. It is the combination of 5.99 inch and Full HD+ resolution that made this model one of the most popular in the history of the brand.
⚠️ Warning: Don't confuse the diagonal of the visible area with the size of the entire body. The frames around the screen, although minimal for its time, add additional millimeters to the dimensions of the device.
It's worth noting that the physical size of the screen directly affects power consumption, and the larger backlight area requires a more capacious battery, which engineers have taken into account when they equipped the smartphone with a 4,000 mAh battery, which allowed them to maintain a balance between brightness and autonomy.
IPS Technology and Quality of Color Translation
The display is based on IPS (In-Plane Switching) technology, which features excellent viewing angles and natural color reproduction, which favorably distinguishes the Redmi 5 Plus from competitors who used cheaper TN-matrix with color distortion when tilted.
The brightness of the screen is about 450 nits, which is an average, and for use indoors or in cloudy weather, this is more than enough, but in direct sunlight, the readability can decrease, because the brightness reserve does not completely interrupt the natural light.
- 🎨 Color coverage: The screen covers about 75% of the color space NTSC, This provides a juicy, but not oversaturated colors that are pleasant to the eye during long reading.
- 👁️ Viewing angles: Thanks IPS-In the matrix, the image does not invert or pale even when viewed from an angle. 80-85 degree.
- 🛡️ Protective glass: The front panel is protected by glass, however, it is not a generation of Gorilla Glass, so it requires careful handling or additional film.
IPS technology also means that there is no “stick loop” effect when you scroll through text quickly, which is important for comfortable reading news and books. The subpixel structure here is standard RGB, which ensures that the finer details of the interface are clear.
💡
To protect the screen Redmi 5 Plus better use protective glass with oleophobic coating, as IPS-matrixes are prone to accumulation of static electricity and attract dust.
Comparison with modern screen standards
With modern smartphones, where 6.5 to 6.7 inches are the de facto standard, the 5.99 inch diagonal may seem modest. However, it is important to consider the evolution of form factors. Modern shovels often have cutouts or holes under the camera, which reduces usable area, whereas the Redmi 5 Plus had classic bezels on top and bottom.
Modern. AMOLED-screens offer deep black and high contrast, but IPS-The matrix in Redmi 5 Plus benefits in durability and no risk of pixel burnout over time.
The screen refresh rate is a standard 60Hz. While the flagships of 2026-2026 offer 120Hz and above, for a budget device of 2018, this was a normal indicator. The smoothness of animations is ensured by optimizing the MIUI shell, not a high hertz matrix.
Compared with modern budget, the Xiaomi Redmi 5 Plus loses only in maximum brightness and support. HDR-And the rest of the image safety margin is still high.
Ergonomics: Is it comfortable to hold 6 inches?
Despite its nearly 6-inch diagonal, the smartphone feels smaller than you would expect, thanks to its 18:9 aspect ratio and relatively narrow body, and the width of the device allows you to confidently embrace it with your palm and reach the opposite edge of the screen with your thumb.
The weight of the device is 180 grams, which for a metal case with a battery of 4000 mAh is an excellent indicator. The smartphone does not feel "brick", but also does not seem too light, creating a feeling of quality, monolithic product.
The arrangement of the controls is designed to keep the girth out of the way, and the fingerprint scanner on the back is in a comfortable area where the finger instinctively goes, which makes up for the lack of face unlock, which was still primitive at the time.
- 📏 Dimensions: 158.5 x 75.4 x 8 mm thick – 8 mm thick makes it easy to remove the phone from your jeans pockets.
- ⚖️ Balance: Center of gravity is shifted to the center, which prevents the phone from falling out when used with one hand.
- 🖐️ Materials: A metal case with plastic antenna inserts provides good grip but can slide in sweaty hands.
For people with a small palm, one-handed control can be difficult, especially at the top of the screen. However, MIUI software features such as one-handed control mode (swipe down the home button) partially solve this problem by reducing the workspace.
The Effect of Screen Size on Autonomy
The big screen is always a high energy consumer, especially when it comes to the energy consumption. IPS-But Xiaomi engineers were able to optimize the Snapdragon 625 processor and matrix bundle so that the device showed impressive results.
With standard use (social networks, calls, a little video), the smartphone can easily withstand a day and a half to two of operation. HD+ consumes more energy than HD-similar, but the battery capacity of 4000 mAh completely covers this consumption.
The brightness of the screen plays a key role in autonomy. If you reduce the brightness to 50% and turn off the autobrightness, you can significantly extend the operating time. IPS-panels.
⚠️ Attention: Continuous use of maximum brightness in the sun can lead to overheating of the case and accelerated battery discharge.
The MIUI energy-saving technology allows you to flexibly adjust the behavior of the screen, so you can set a screen timeout of 15 or 30 seconds to make it go out faster when you're not using the phone, saving you charge.
☑️ Optimizing the screen for the battery
Configure the display in MIUI
The MIUI shell installed on the Redmi 5 Plus provides ample options for customizing the look of the image. The user can adjust the color temperature, choosing between cold and warm shades to adapt the screen to their preferences.
To access the settings, you need to go to the Settings menu → Screen. → Colors and saturation. You can choose one of the preset profiles or you can adjust the settings manually, which is especially useful because factory calibration can seem too cold to someone.
Read Mode is also available, which puts the screen into monochrome sepia mode, mimicking electronic paper, which reduces eye strain during long-term reading and saves battery power by turning off some subpixels.
The font size and interface elements can be changed in the section Additional → Text size. Given the diagonal of 5.99 inches, standard settings are usually enough, but for people with visual impairment, the option of zooming to giant sizes is available.
The path to hidden settings (via the engineering menu, requires caution):
##6484## -> Item 4 (LCD Test)Using night mode, which reduces the amount of blue spectrum, helps to preserve circadian rhythms when using a smartphone in the evening, and on IPS-matrixes, this effect is noticeable immediately, as the image becomes yellowish.
Frequent Display Problems and Their Solutions
Despite its reliability, the Redmi 5 Plus has specific screen problems, one of which is the yellow veil or the uneven lighting around the edges (the effect of lights), which is characteristic of the Redmi 5 Plus. IPS-side-light panels.
Users also sometimes complain of a decrease in touchscreen sensitivity after falling or getting moisture, in which case calibration of the sensor through an engineering menu or a complete flashing of the device can help.
If you see broken pixels (dots that don't change color), use software recovery techniques that quickly change the colors on the screen to try to "pattern" the stuck subpixel.
| Problem. | Probable cause | Decision |
|---|---|---|
| Screen flickering | Low brightness (PWM) | Increase brightness or turn on the protection mode of vision |
| Spots on the display | Pressure on the matrix | Replacement of screen module (not repaired) |
| The touch doesn't work. | Software failure or plume | Flashing or replacing the touchscreen |
| Dim screen | Wearing backlights | Replacement of LED tape or module |
