When choosing a smartphone or a smart device Xiaomi, many are faced with the designation of the letter S at the end of the model name – for example, the Redmi Note. 12S, Mi 11S or POCO X5 Pro 5G S. This may seem like a random marketing ploy at first glance, but in fact, there are specific technical and functional differences behind this letter. In some cases, the S version is more profitable than the standard one, and sometimes, on the contrary, it loses to it in key parameters.
In this article, we will discuss in detail what Xiaomi’s S means in different device lines, how such models differ from the basic versions, and whether it is worth overpaying for this letter.
- 🔍 The history of the emergence of S-models in the Xiaomi ecosystem and their evolution.
- 📱 Key differences between S-versions of smartphones from standard (processor, camera, battery).
- 💡 Advantages and Disadvantages of Buying S-S Devices.
- ⚠️ The pitfalls that the sellers are silent about.
We will focus on real-world tests and comparisons, such as why the Redmi Note is a good example. 11S It may be more interesting than the Redmi Note 11 Pro for certain tasks. 10S It's different from the Mi 10, except for the chipset. If you're faced with a choice between the S model and the standard version, this article will help you make an informed decision.
1. The history of the letter S in Xiaomi names: where did it come from?
Xiaomi’s tradition of adding the letter S to device names is not accidental, and this is the first time that this approach has been used in the line of flagship Mis, such as the Mi. 5S (2016 was an improved version of the Mi 5, but the roots go deeper: similar markings were borrowed from other brands, where the S often stood for Sport (sports version), Special (special) or Superior (improved).
In Xiaomi’s context, the letter S originally meant intermediate updates to flagship models, such as:
- 📅 Mi 8 (2018) → Mi 8 Pro → Mi 8 SE (simplified) → Mi 8 Lite → Mi 8S (2019, with Snapdragon 855 processor).
Over time, the approach has evolved: whereas S-models used to be improved versions of flagships, now they are more likely to act as simplified or specialized variants. 12S (2023 Gets Mediatek Helio processor G96 Snapdragon instead 778G Redmi Note 12 Pro+, It also has a 108MP camera and AMOLED-screen.
⚠️ Note: Do not confuse the S-model with the S-model. SE (Special Edition, or Lite, are different rulers, like the Mi 11 Lite and the Mi. 11S They solve different problems: the first is cheaper and weaker, and the second can be more powerful than the basic model, but with other compromises.
2. How Xiaomi S-models differ from standard: technical analysis
The main difference between the S-versions and the basic models lies in the hardware stuffing and the target audience. Let's look at the key parameters using the example of popular lines.
Processor and performance
Most S models get a different chipset, which can be either more powerful or weaker than the base version.
- 🔥 POCO F3 (Snapdragon 870) vs POCO F3 GT (Mediatek Dimensity 1200) vs POCO F3 S (Snapdragon 780G) — The S version is weaker than both.
It’s important to understand that performance doesn’t always correlate with the letter S. Sometimes it’s just rebranding to another region or simplifying to lower the price.
Camera and multimedia
In some S-models, the camera can be improved or simplified, for example:
- 📸 Mi 11 (108 MP) + 13 MP + 5 MP) vs Mi 11S (108 MP + 8 MP + 5 MP - here removed the telephoto module.
There are exceptions, however: Redmi Note 12S Retained 108MP camera from Redmi Note 12 Pro, but lost the 50-MP ultra-wide module.
Screen and design
In terms of design, S-models usually copy the basic version, but may differ:
- 🖥️ Type of matrix: for example, POCO X3 NFC (IPS) vs POCO X3 Pro (IPS) vs POCO X3 GT (AMOLED).
To sum up, S doesn't guarantee improvement. Sometimes it's just a reallocation of priorities -- like a weaker processor, but a better camera or battery.
💡
Xiaomi S models can be both improved and simplified versions of the base devices. Always check specific specs before buying.
Why Xiaomi Is Launching S Models: Marketing or Real Need?
The S-versions have several goals, and not all of them are technologically advanced.
- Market segmentation. Xiaomi is covering more price niches in this way.+ (≈35 000 ₽) Redmi Note 12S (≈25 000 ₽) They attract different audiences with similar designs.
- Residual parts: Sometimes S models are assembled from spare parts from previous generations (e.g. processors or cameras) to reduce cost.
- Testing new solutions. For example, Mi 10S It was the first model to feature the Snapdragon 870, which was later used in the POCO F3.
- Regional adaptation: Some S models are only available for specific markets (e.g. Redmi) 9S for India).
And the marketing component is there, too, where the S creates the illusion of "special" devices, even if they're basically repackaged old models, POCO M3 and POCO M3 Pro 5G They differ dramatically, and POCO M3S — It's just that. POCO M3 with a different processor (Helio) G95 Snapdragon 662 instead).
⚠️ Warning: If you see an S model with a suspiciously low price tag, check the release date. It may be an outdated device that has been renamed for the new year. 9S (2020 and Redmi 9A Sport (2021) is technically almost identical.
4.Pros and cons of buying S-models Xiaomi
To understand whether to take a device with the letter S, weigh all the pros and cons.
| The advantages of S-models | Cons of S-models |
|---|---|
| ✅ Often cheaper than the basic versions with similar characteristics. | ❌ It may have an outdated processor (e.g., Helio) G96 Snapdragon instead 7xx). |
| ✅ Sometimes saves key features flagships (for example, the 108-MP camera in the Redmi Note). 12S). | ❌ Short term support for updates (S-models are often referred to as "secondary" rulers). |
| ✅ Unique color options or design solutions. | ❌ It is more difficult to find on sale (limited batches). |
| ✅ It can be lighter and thinner due to simplified filling. | ❌ Fewer accessories (cases, glass) due to low popularity. |
One of the major pitfalls is software updates. Xiaomi often prioritizes basic and Pro models, so the S versions can get updates later or not at all. 9S got MIUI 12 a year later than the Mi 9.
Another nuance is the market position, and some S models are released as trial models before a full upgrade. 10S It was released six months before the Mi 11, which made it irrelevant after a few months.
💡
Before buying an S-model, check the date of its announcement. If it's been more than a year, a more relevant replacement will likely be released soon.
5. How to distinguish a profitable S-model from a failed one: a checklist for the buyer
To avoid losing your choice, follow this algorithm:
☑️ Checking the S-model before buying
An example of a successful S-model: Redmi Note 12S. She got it:
- 📷 108MP camera from the Pro version.
- 🔋 5000 mAh battery with fast charging of 33 watts.
- 💰 Price 30% lower than the Redmi Note 12 Pro+.
An example of a failed S-model: POCO M3S. She's losing even to the baseline. POCO M3 down:
- 🔄 Screen (60 Hz vs 90 Hz in) POCO M3 Pro).
- 📡 Support 5G (absent).
- 🔋 Charging (18 W vs 33 W).
Critical: S-models often lack support 5G, Even if the base version has it, like the Redmi Note. 11S It only works on networks. 4G, The Redmi Note 11 Pro 5G Supports new standards.
6. Comparison of S-models with other Xiaomi lineups: SE, Lite, Pro
To finally understand the marking, compare the S-model with other suffixes:
| suffix | What does it mean? | Example | Target audience |
|---|---|---|---|
| S | Special or simplified version (may be better or worse than the base version). | Redmi Note 12S, Mi 11S | Buyers looking for a balance of price and features. |
| SE | Special Edition is usually a simplified or compact version. | Mi 11 SE, POCO X3 SE | Those who need a small size or a low price. |
| Lite | Lightweight version with reduced characteristics. | Mi 11 Lite, Redmi 9 Lite | Budget buyers who don’t need high performance. |
| Pro | An improved version with top features. | Redmi Note 12 Pro+, POCO F4 Pro | Gamers and enthusiasts willing to pay for the maximum opportunity. |
The main difference between S and S SE/Lite — If Lite is always weaker than the base model, then S can be both better and worse:
- ✅ Mi 10S (> Mi 10 processor).
- ❌ POCO X3 NFC (> POCO X3 S by screen and camera).
If you see the name Pro S (for example, the name is, POCO X5 Pro 5G S, this usually means a regional modification of the Pro version with minor changes (for example, a different set of frequencies for a mobile network).
Why are some S-models not sold in Russia?
7.The future of S-models: What to expect from Xiaomi in 2026-2026
Analyzing the trends of recent years, we can predict several scenarios for the development of S-lineas:
- More "renamed" devices. Xiaomi will be more active in using the letter S to rebrand old models under new names (as it did with the Redmi 10 2022, which is actually the Redmi). 9S).
- Focus on cameras and batteries. S-models will retain top-end cameras or batteries from Pro versions, but with simplified processors (like in the Redmi Note). 12S).
- Regional specialization: S models will be developed for specific markets (e.g. Europe with additional support for the development of the model). 5G-range).
- It is possible that Xiaomi will gradually abandon the letter S in favor of more understandable designations (for example, the Redmi Note 13). 4G Redmi Note instead 13S).
Xiaomi is already seeing a reduction in the number of S models in new lines, for example, in the Redmi Note 13 series (2026) there is no model with the letter S – instead, the Redmi Note 13 appeared. 4G Redmi Note 13R. This may indicate that your marketing strategy is changing.
If you are planning to buy for 2026-2026, pay attention to:
- 🔍 The date of the announcement – if the model came out more than a year ago, it is already morally outdated.
- 📦 Global version: Some S-models are sold only in Asia.
- 🔄 Alternatives without the letter S – sometimes the basic model is more profitable.
