In this article, we will take a closer look at the design of the Redmi Note 9, including dimensions, control layout, color options and build nuances. You will also learn how to distinguish the original model from a fake by appearance and what to look for when buying a used device. If you are planning to buy this smartphone or just interested in the evolution of Xiaomi design, this information will be useful.

Dimensions and weight: compactness vs. ergonomics

The Redmi Note 9 is a big-screen smartphone, but it still has a reasonable size for a single hold in the hand, measuring 162.3 × 77.2 × 8.9 mm and weighing 199 grams. In comparison, it’s slightly heavier than the iPhone 12 (164 g), but lighter than many modern flagships with high-capacity batteries.

The 8.9mm thickness of the case is attributed to a massive 5,020mAh battery, one of the key advantages of the model, and it doesn’t look bulky because of its rounded edges and weight distribution, but it can take users with small hands a while to get used to its size.

Fun fact: Despite the large screen size (6.53 inches), the Redmi Note 9 is held with one hand thanks to its narrow bezels (especially the sides) and slightly elongated shape, achieved by having a 19.5:9 aspect ratio that makes the body more ergonomic than the square-sized models.

Materials of the case: plastic vs. glass

Unlike Xiaomi’s flagship models, which use glass frequently, the Redmi Note 9 is made of matte plastic with metal texture.

• ✅ Durability: Plastic is less prone to cracking when falling than glass.
• ✅ Weight: the body is lighter than glass counterparts (for example, the Redmi Note 9 Pro weighs 209g).
• ✅ Tactile sensations: matte surface does not slide in the hands and does not collect fingerprints.
• ❌ Appearance: Plastic looks less premium than glass or metal.
• ❌ Wear: Over time, scratches may appear on glossy inserts (such as around the camera.

The back panel has a gradient pattern that changes shade depending on the angle of light, which gives the smartphone a more expensive look than many budget competitors, and the side faces are also plastic, but with a metallized coating that mimics aluminum.

⚠️ Note: Some vendors are giving the Redmi Note 9 to the Note 9 Pro, citing “similar designs” and can be distinguished by the body material – the Pro version has a glass back panel, as well as the location of the fingerprint scanner (the Note 9 has it on the back, the Pro has it in the power button).

Location of buttons and connectors

The Redmi Note 9's ergonomics are very detailed, with all the controls and connectors arranged so that they can be used with both the right and left hand, and here's their exact location:

• 🔘 Power button: right end, just above the middle, has a grooved surface for better grip.
• 🔊 Volume buttons: also on the right end, above the power button, placed close together, which eliminates accidental pressing.
• 📶 Tray for SIM-map: left end. Supports 2 nano-SIMs + microSD (hybrid slot).
• 🔌 Connector. USB Type-C: Downtown, next to it is a speaker, a microphone and a 3.5mm audio jack.
• 🎤 Second microphone (for noise reduction): in the upper part of the body.
• 📸 Main camera: in a vertical block in the upper left corner of the rear panel.

The model features an infrared port on the upper end that allows you to use your smartphone as a remote control for home appliances, a rare solution for budget devices that many users have appreciated.

Color options: which one to choose?

Xiaomi Redmi Note 9 is available in three official colors, each with a unique gradient effect:

1. Polar White: combines white and silver with pearl shimmering, looks more neutral and less brandy than the darker options.
2. Midnight Grey: A classic dark shade with metallic luster, suitable for those who prefer a strict design.
3. Forest Green: Deep green with a bluish tint, the most unusual and bright variant of the line.

When choosing a color, consider that: the white version visually makes the smartphone larger, but it is less noticeable scratches; gray - universal, but quickly gets dirty; green - original, but may not like everyone because of the saturation.

Important: Some vendors offer "exclusive" colors (e.g. blue or purple), but these are often unofficial modifications or fakes. The original Redmi Note 9 was only available in the three above-mentioned variants.

Screen: frame, cutout and protection

Redmi Note Display 9 — it IPS-diagonal 6.53 inch and resolution 2340 × 1080 pixels (Full) HD+). Its key features:

• 📱 Screen to body ratio: ~83.5% due to narrow frames (especially on the sides).
• 🔄 Upgrade frequency: standard 60 Hz (unlike Note 9 Pro with 120 Hz).
• 🛡️ Protection: Gorilla Glass 5, resistant to scratches and light impacts.
• 🌈 Color Transfer: Support for the Standard DCI-P3, without certification HDR.

At the top of the screen is a drop-shaped cutout for the front camera, smaller than the monobrow in older models (like the Redmi Note 8), but takes up more space than the screen hole (like the Redmi Note 10), which does not interfere with viewing content, since most applications are adapted to it.

The brightness of the screen reaches 450 nits, which is enough for comfortable use outside in sunny weather. However, when directly hit by sunlight, glare can occur - in such cases, it is recommended to increase the brightness manually or turn on Reading mode in the display settings.

💡

To reduce eye strain, activate Dark Theme mode in settings (Settings → Display → Dark Theme) and this will also save 5-10% on battery life.

Camera: block design and features

The rear module of the Redmi Note 9 camera is made in the form of a vertical rectangle with four lenses and LED-The block protrudes slightly above the body (about 1 to 1.5 mm), which can cause scratches when placing the smartphone on the table with the screen up:

• 📷 Main camera: 48 MPP, f/1.79, phase-autofocus.
• 🌄 Wide-angle camera: 8 MP, angle of view 119°, f/2.2.
• 🔍 Macro lens: 2 MP, for shooting from a distance of 4 cm.
• 🎭 Depth Sensor: 2 MP, for Portrait Mode.

The design of the chamber unit is often criticized for its asymmetrical layout, with the main lens shifted closer to the left edge, which may seem unaesthetic, but this decision is due to the internal layout of the board and the cooling system.

The glass that covers the chambers has an oleifobic coating that repels fat and dust, but it is easy to scratch, so it is recommended to use a case with a cutout for the module or put a protective film on it.

⚠️ Warning: If you notice that the glass above the cameras has started to flake off or crack for no apparent reason, this may be a sign of overheating of the device (for example, during prolonged play or charging). CPU Monitor and contact the service center if necessary.

How to distinguish the original from the fake on the external signs

The popularity of the Redmi Note 9 has brought a lot of counterfeits to the market, especially in the used device segment, and here are the key external signs that can be used to recognize the original:

The MI logo on the back is metal, with clear faces (forgeries often have a sticker)

The inscription “Designed by Xiaomi” under the camera – with a uniform font and without spelling errors

USB-Type-C connector with symmetrical contacts (copies often have microUSB)

Fingerprint scanner round, with backlight when touched

-->

Additional details that should be paid attention to:

1. Packaging: The original box has a holographic sticker with a serial number that matches the number on the phone (checked in Settings → About Phone).
2. Fonts: all inscriptions on the original (including small ones on the tray) SIM-maps) are made carefully, without blurring.
3. Weight: Counterfeiting is often lighter due to cheap materials (the original weighs exactly 199g).
4. Sound: The speaker of the original produces a clear sound without wheezing at maximum volume.

If you buy a smartphone with your hands, be sure to check it through the official Mi Verify app (available on Google Play), it scans IMEI and confirms the authenticity of the device, and it will not be superfluous to check the operation of all cameras, sensors and wireless modules (Wi-Fi, Bluetooth, NFC - if you have one in your modification).

💡

Even if the smartphone looks like the original, fakes are often given out by software. Note the MIUI version - the original Redmi Note 9 should be at least MIUI 12 (at the time of release).
