Xiaomi Mi 9 SE weight: official data, comparison and why it matters

Introduction: Why the weight of a smartphone matters

When choosing a new smartphone, users usually pay attention to the processor, camera or memory capacity. But there is one parameter that often stays in the shadows, although it directly affects the comfort of use: the weight of the device. Xiaomi Mi 9 SE, released in 2019, was one of the most compact flagships of its time, but its mass raises questions among many potential buyers, especially for those who are moving from lighter models or plan to use the phone with one hand.

In this article, we will not only reveal the exact weight figures of the Mi 9 SE with all components in mind, but also compare it with other popular Xiaomi models of the same period. You will learn how the mass is distributed inside the case, why some instances can weigh slightly more than stated, and what this affects when used daily. And for those who are planning to buy a used device, we have prepared a checklist for the originality of the case - because counterfeits often differ in weight!

Xiaomi Mi 9 SE official weight: what the manufacturer says

According to the technical specifications from Xiaomi, the mass of the Mi 9 SE This figure is listed on the official website of the brand and in the documentation for the device, but it is important to understand that the manufacturer usually gives the weight of the naked smartphone without taking into account the weight of the naked smartphone. SIM-In real-world applications, this value is added to the value of a card, a protective film or a cover:

• 📱 SIM-map: +1–2 gram (depending on type) nano/micro)
• 🛡️ Protective glass: +3-8 grams (depending on thickness)
• 👜 Cover: from +10 grams (thin silicone) to +30 grams (leather or armored)

In everyday use, the weight of the Mi 9 is SE It can reach 170-190 grams. This is still lighter than many modern flagships (for example, the iPhone 15 Pro Max weighs 221 g), but heavier than budget models like the Redmi Note 12 (188 g). SIM-cards) may be 1-2 grams heavier than the global one due to the additional slot.

Weight distribution inside Xiaomi Mi 9 SE: which is the hardest?

To understand where the 155-gram mass comes from, let's look at the key components.

1. The battery (3070 mAh) is about 45-50 grams. Lithium-polymer batteries of this volume usually weigh just that, plus or minus 2-3 grams due to variations in production.
2. The display (5.97, AMOLED) is about 30 grams. Gorilla Glass 5 and the aluminum frame add strength, but also weight.
3. A processor (Qualcomm Snapdragon 712) with a cooling system - about 10-12 grams. A copper radiator to remove heat increases this figure.
4. Three cameras (48+13+8 MP) – a total of 15-18 grams Optics with sapphire glass and stabilization weigh more than simple modules.

The remaining grams are distributed between the motherboard, speakers, vibration motor and small components. Curiously, the Mi 9 SE uses an aluminum body with plastic inserts for antennas – this is easier than models with a fully glass rear panel (for example, the Mi 9 weighs 173 g).

Comparison with other Xiaomi models: who is lighter, who is heavier

To appreciate how much the Mi 9 SE stands out in terms of weight, compare it with other popular smartphones of the brand from 2018-2020. Note: compact dimensions (147.5×70.5×7.5 mm) allow the device to remain one of the lightest in the line of flagships.

• 📱 Xiaomi Mi 9 - 173 g (large battery 3300 mAh and glass case)
• 📱 Xiaomi Mi 9 Lite – 179g (plastic body, but thicker)
• 📱 Xiaomi Mi 10 - 208g (metal) + glass, battery 4,780 mAh)
• 📱 Redmi Note 8 Pro – 200 g (budget, but with a massive body)
• 📱 POCO F1 — 182 g (plastic but large battery 4000 mAh)

As you can see, the Mi 9 SE is much lighter than most of its peers, except for ultra-budget models like the Redmi 7A (165 g), but they lose in performance. Interestingly, despite the lower weight, the Mi 9 SE has a more premium build than many of the devices in the Redmi lineup, which use cheap plastic.

Xiaomi Mi 9 SE — One of the lightest flagships of 2019 among devices with AMOLED-It weighs 155g and is optimal for single-handed use, but not at the expense of strength.

How weight affects usability: pros and cons

Light weight is not always an unambiguous plus, and consider how 155 grams affect the daily use of the Mi 9 SE:

⚠️ Warning: Smartphones that are too light (less than 140g) are often perceived as "cheap" or fragile.Mi 9 SE It is located on the border of this threshold - its mass is sufficient for the sensation of a premium device, but does not tire the hand.

• ✅ Pluses: 🖐️ It is convenient to hold one hand even with prolonged use (social networks, instant messengers). 👜 Less load on clothing pockets – doesn’t pull jeans or shirt down. 🎮 Suitable for gamers: less tired wrist when horizontally holding.
• ❌ Cons: 🔋 Smaller battery (3070 mAh) due to weight restrictions – lower autonomy than heavy flagships. 🔊 Weak bass in dynamics: lightweight body worse resonates low frequencies. 💨 Heats up faster under load: less mass to distribute heat.

For comparison, the iPhone SE (2020) weighs 148g and has similar pros/cons, but loses the Mi 9 SE in screen diagonal and camera count. If you care about autonomy, look at the POCO X3 NFC (215g, but the battery is 5160mAh).

To compensate for the light weight and improve grip, use a case with rubber inserts or matte coating.This will prevent slipping out of the hand, especially in winter with gloves.

How to check the weight of Xiaomi Mi 9 SE when buying used: checklist

When buying a used Mi 9 SE, weight can be one of the indicators of originality. Fraudsters often give off redmi Note 7 or other models as Mi 9 SE.

Weigh the device on an exact scale (error) ±1g)|The original weighs 155g without SIM-map

Check the weight distribution: the battery must shift the center of gravity to the bottom | Counterfeiting often has a uniform weight

Note the material of the case: aluminum + glass (not pure plastic) | Plastic is usually lighter by 10-15 g

Compare the weight of the box: the original packaging weighs ~300g |Fake boxes are often lighter and thinner

If the weight of the device differs from 155 g by more than 3-5 grams, this is a reason to be wary.

• 🔋 Smartphone is heavier – perhaps installed non-original battery of higher capacity (for example, 4000 mAh instead of 3070 mAh).
• 🪨 Smartphone lighter – could replace the aluminum frame with a plastic or remove the vibration motor.

⚠️ Warning: Some sellers deliberately indicate the wrong weight in ads to hide the fact of repair. Always ask for a picture of the device on a scale with a clear display of the model.
