The question of how much the Xiaomi Mi Band 4 watches cost in 2026 has ceased to be a simple query for those looking for a novelty, and has transformed into a complex analytical task for connoisseurs of budget electronics. This activity tracker, released a few years ago, has managed to go from a no-contest market leader to a niche product that is sought by either collectors or users with a very limited budget. The wearable electronics market is moving rapidly, and models that were considered relevant only yesterday are now going to secondary sites or disappear from sale.
The pricing situation for the Mi Band 4 is very heterogeneous now: you can find offers with a symbolic price for a device without warranty and options “as new” at prices that cause confusion. Understanding the real cost of this gadget requires considering many factors, from the state of the battery to the availability of the original packaging. In this article, we will analyze the current market prices, analyze the feasibility of buying and compare the cost of ownership of this device with more modern analogues.
It is worth noting that finding the new Mi Band 4 in the official retail of large chains is almost impossible, since production lines have long been reoriented to newer series. Marketplaces, bulletin boards and small electronics stores that sell the remains of inventory are the main sites for search.
Current market value and pricing factors
At the moment, the average cost of Xiaomi Mi Band 4 in the secondary market varies in a wide range, which directly depends on the configuration and technical condition of the device. If you consider the offers on popular ad platforms, the minimum entry threshold is the amount equivalent to the cost of a simple lunch, but for this money you will most likely get a device with a battery life or screen defects.
Devices in the “perfect” or “new in a sealed box” state can cost two to three times more, approaching the price of promotional offers for more recent fifth- or even sixth-generation models. This creates a paradox when overpaying for the status of “new” old gadget becomes economically impractical, sellers often unreasonably overpriced, arguing that the product “never wore”, forgetting about the natural degradation of battery chemistry over time.
The key factors affecting the final price are:
- 📦 Complete: The original box, instructions and, critically, a charging cable that is specific to this model.
- 🔋 Battery status: For a device several years old, this is the main parameter; a tracker that holds a charge for less than 3 days loses half of its value.
- 💧 Water protection: Proven tightness of the body increases the value of the lot, since the used devices eventually dry up seals.
Also worth considering is the color variation of the capsule and strap: Standard black versions are always more liquid and cost a little more than rare colors if it is a collector's edition, or cheaper if it is a mass segment. In the case of the Mi Band 4, color affects the price indirectly, through the demand for specific shades of straps, which often come with a bundle.
⚠️ Note: If you see a new Xiaomi Mi Band 4 offering at a price higher than the price of the new Mi Band 6 or 7, it is a clear sign of an unreasonable overprice by a seller who does not follow the market.
Price comparison: Mi Band 4 vs. newer models
To understand how much Xiaomi Mi Band 4 watches actually cost in the context of modernity, we need to draw a parallel with their direct successors: the difference in price between the fourth generation and the fifth, sixth or seventh generation models can be minimal, especially when considering new devices with an official warranty.
The Mi Band 5 received magnetic charging, which immediately solves the problem of wear of contact platforms, and also added a sensor to measure oxygen in the blood and improved sleep monitoring. Mi Band 6 brought frameless AMOLED-It's a screen that changes the way we think about the interface, and it's an expanded set of sports modes. It only makes sense to overpay for the Mi Band 4 in 2026 if the budget is tight and the availability of a budget is tight. NFC or SpO2 is not critical.
Let’s look at the price ratio (conditional units) to understand the market situation:
| Model | Average price (B/O) | Average price (New) | The key difference |
|---|---|---|---|
| Mi Band 4 | Low. | Medium (rarely) | Basic functionality, removable capsule module |
| Mi Band 5 | Medium | Tall. | Magnetic charging, SpO2 sensor |
| Mi Band 6 | Tall. | Very high. | Frameless screen, 30+ sports modes |
| Mi Band 7/8 | Very high. | Premium | Always on screen (AOD), large sizes |
As you can see from the table, the overpayment for switching to one model higher can be small, but the increase in user experience is significant. If the Mi Band 4 costs 15-20 c.u., then adding 50% to this amount, you can get a device with a new generation screen and relevant software. However, for those who just need a pedometer and notifications, the fourth model remains a workhorse.
💡
Buying the Mi Band 4 in 2026 is only justified on a very low budget or the need for specific accessories that are incompatible with new models.
Where to look for profitable offers and how not to buy a fake
The search for Xiaomi Mi Band 4 in 2026 is turning into a quest, as official sales channels have long since cleared the shelves of this model, with the main sources being ad platforms (Avito, Yula), Chinese marketplaces (AliExpress, Ozon Global) and local social media groups, each with its own risks and benefits that directly affect the ultimate cost of ownership.
There is a high risk of running into devices with hidden defects, such as a "dried" battery or a broken pulsemeter. Chinese sites offer a new product, but there is a high probability of getting a replica or a restored unit, identifiable as the original. The original devices have a clear engraved on the back of the capsule, high-quality font and perfectly matched contacts.
- 🔍 Verification QR-Code: The back of the original tracker should be readable QR-code that is scanned by Mi Fit or Zepp Life.
- 📱 Application Pairing: A fake may not connect to an official application or require the installation of third-party software with a dubious reputation.
- ⚖️ Weight and materials: The original capsule has a specific weight and (feeling the material), cheap plastic fakes often give cheapness and has a backlash button.
When buying from hand, be sure to demand video of the device’s performance, which shows battery life and sensor response. It’s also worth checking the firmware version: if the device hasn’t been updated in years, this may indicate rare use or technical problems. For the Mi Band 4, the latest versions of the software released by the manufacturer before the end of support are relevant.
⚠️ Warning: Avoid buying trackers that are sold without a branded packaging and charger, as finding compatible charging for the Mi Band 4 at retail is becoming increasingly difficult.
How to distinguish the restored Mi Band 4?
Hidden expenses: straps, charging and accessories
When buying the Xiaomi Mi Band 4, many people forget that the initial price is just the beginning of the cost. The unique design of this bracelet, where the capsule is removed from the strap, is convenient on the one hand, and on the other creates a dependence on accessories. The straps for the fourth model are still available, but their range is narrowing, and the quality of cheap counterparts leaves much to be desired.
The biggest problem is the charger. Because the Mi Band 4 uses contact charging to remove the capsule, the loss or failure of the "tail" of charging turns the tracker into a useless piece of plastic. Finding the original charging separately is difficult, and Chinese counterparts often have poor contact, which leads to undercharging or, conversely, overheating of the battery.
Additional costs can also include:
- 🛡️ Protective Glasses: The Mi Band 4 screen is subject to scratches, and buying protective films or glasses is a must-have expense.
- 🔌 Adapters: Often chargers are sold without USB-The unit that must be kept separately.
In the long run, the cost of ownership of the Mi Band 4 could rise by 30-40% of the original price of the device due to the need to replace consumables, making buying newer models, where magnetic charging and straps are standard for several generations, a more cost-effective strategy.
💡
Buy straps for Mi Band 4 immediately set of 3-5 pieces in Chinese sites - it will be cheaper than to look for them separately in local stores.
Technical Limitations and Impact on Price
Understanding the technical limitations of the Xiaomi Mi Band 4 helps to estimate its cost. In 2026, the lack of some features that have become standard makes this gadget obsolete, for example, the lack of a full-fledged blood oxygen sensor (SpO2) and the inability to install third-party dials (without complex manipulations) significantly reduce its market attractiveness.
The device's screen, though AMOLED, has notable bezels at the top and bottom, making it visually smaller than its competitors.The processor and memory space limit the speed of the interface and the amount of data stored. Software support is also coming to an end or already complete, meaning no new features and security patches are available.
However, for basic tasks, the device remains powerful:
- ✅ Accurate calculation of steps and calories.
- ✅ Monitoring of sleep and pulse (basic).
- ✅ Notification and management of music.
If you want this minimalist feature without the bells and whistles, the Mi Band 4 could be a great choice for pennies, but it should not be a full-fledged smart gadget. Its price should be symbolic, reflecting the status of "past generation technology."

To sum up, the Xiaomi Mi Band 4 in 2026 is a very narrow niche device, and it only makes sense to buy it in three ways: a very limited budget, a need for a spare tracker, or specific design requirements (e.g., certain old straps are needed).
The price of the Mi Band 4 should be minimal. It makes no sense to pay full price for a device that is obsolete. The market dictates its terms, and the value of a gadget is determined not only by its technical characteristics, but also by the relevance of the software and the availability of accessories.
If you do decide to buy, carefully check the condition of the battery and equipment. Remember that the stingy pays twice: buying a cheap tracker with a dead battery, you will spend more time and nerves on its maintenance than you saved money.
