The affordable smartwatch market is more competitive than ever

Finding a good smartwatch for up to R$ 500 in 2026 is a different task than it was two or three years ago. The category has matured significantly: today you can get heart rate monitoring, SpO2 (blood oxygen saturation), GPS and smart notifications without spending the price of an iPhone. The challenge has shifted: it’s no longer “is there anything decent in this range?”, but rather “which one works for my case?”

In this comparison, you’ll find the models that appear most frequently in Brazilian searches and shelves in this price range, focusing on official specifications, national availability and what each one actually delivers. The short answer: the Xiaomi Smart Band 10 Pro and Amazfit GTR Mini are the most balanced for most profiles, but there are cases where the Realme Watch 3 Pro or Huawei Band 9 make more sense. Keep reading to understand why.

Quick comparison: main models under R$ 500

Prices based on stores like Mercado Livre, Shopee and Amazon Brasil, with frequent variation. Always check the current price before purchasing.

Xiaomi Smart Band 10 Pro: the upgrade Brazil needed

The Smart Band 10 Pro arrived in 2025 as the most complete version of Xiaomi’s Band line, bringing built-in GPS, which was the main complaint of the previous generation. According to the manufacturer, the 1.74-inch AMOLED screen offers brightness of up to 1000 nits, sufficient for reading outdoors on sunny days.

The declared autonomy is up to 14 days in normal use, which in practice, with GPS enabled and continuous heart rate monitoring, should drop considerably. Xiaomi doesn’t detail the usage scenarios precisely in the technical sheet, so treat the 14 days as the optimistic ceiling. The Zepp Life app (formerly Mi Fit) works on both Android and iPhone and is one of the most complete in the category in terms of data history and sleep analysis.

For those who run or cycle casually and want training data without paying a lot, the Smart Band 10 Pro is probably the best value for money on the list. If you want to understand more about the Xiaomi ecosystem for connecting the device to iPhone, there’s a complete guide on how to connect Xiaomi Smart Band 10 to iPhone that covers the setup process from scratch.

Amazfit GTR Mini: for those who want a real watch look

The GTR Mini has a different aesthetic appeal from strap models. The round shape with 42mm case and silicone strap looks much more like a conventional watch than a fitness tracker, which matters for those who use the device in professional environments.

The 1.28″ AMOLED screen is smaller than the competition, but the 416×416 pixel resolution ensures dense visual density and readable text. According to Amazfit, autonomy reaches 20 days without GPS and about 8 hours with GPS active. The built-in GPS with support for multiple satellite systems (GPS, GLONASS, BeiDou) is a strong point for outdoor activities.

The GTR Mini doesn’t have a microphone or speaker, so calls from the wrist are out of the question. For health and sports monitoring, however, the technical sheet is solid: continuous heart rate, SpO2, skin temperature, over 120 sports modes and the Zepp app, which has good usability. It’s a good choice for those who value aesthetics and long battery life, but don’t depend on answering calls from the watch.

Huawei Band 9: the cheapest on the list with a good screen

The Huawei Band 9 stands out for its price: you can find it for less than R$ 300 frequently. The 1.47″ AMOLED screen is generous for a smartband and the manufacturer declares autonomy of up to 14 days. The finish is thin and lightweight, with less than 14g on the wrist according to Huawei.

The most important downside is the lack of built-in GPS. The device uses your phone’s GPS when connected, which means you need to carry your phone during runs if you want to track the route. For treadmill runners or those who just want to count steps and monitor sleep, that’s not a problem. For street runners or cyclists, it’s an eliminating factor.

The Huawei Health app works well on Android, but on iPhone the experience is more limited due to Apple’s restrictions on third-party apps. If you use iPhone, verify the compatibility of the current app version before buying. The Band 9 is approved by Anatel and is sold in Brazil by Huawei itself and authorized resellers.

Redmi Watch 4: the largest screen in the category

The Redmi Watch 4 has the most generous screen on this list, with 1.97″ AMOLED. For those who use the smartwatch to read long notifications or prefer an interface with larger elements, this difference is noticeable day-to-day. Xiaomi/Redmi declares autonomy of up to 20 days, with integrated GPS and NFC support for payments, depending on the version and feature availability in Brazil.

NFC for payments in Brazil still depends on integration with specific banks and payment networks, and doesn’t always work with Brazilian digital wallets like Google Pay. Before buying, confirm that the version available for Brazil has NFC active and which institutions are compatible with your bank.

The design is more square and bulky than the other models, which can be uncomfortable on smaller wrists. But if you want the most immersive screen in the R$ 500 range, the Redmi Watch 4 delivers exactly that.

Realme Watch 3 Pro: large screen, short battery

The Realme Watch 3 Pro has a 1.78″ LCD screen, which delivers less contrast and less sharpness than the AMOLED models on this list. The critical point, however, is autonomy: according to the manufacturer, it’s up to 5 days with typical use, well below the competition. That means charging twice a week.

It has built-in GPS, heart rate and SpO2, plus a design with a large rectangular case. It’s the cheapest model with GPS on this list, but the cost-benefit is compromised by the short battery and LCD screen in a price range where AMOLED is already standard. It works for those who want cheap GPS and don’t mind charging the device frequently.

Which smartwatch to choose by profile

Time to be direct, because specifications without context don’t decide anything.

If you run or bike and want GPS without spending much: The Xiaomi Smart Band 10 Pro is the most balanced choice. Built-in GPS, good screen and app with decent training analysis.

If you wear the watch at work and want a more discrete look: The Amazfit GTR Mini has the best design on the list for professional environments and battery that holds up well.

If you just want basic monitoring and the lowest price possible: The Huawei Band 9 does the job with plenty to spare, as long as you don’t need built-in GPS.

If you want the largest screen available in this range: The Redmi Watch 4 has no rival in that regard. But confirm NFC availability before paying more for it.

If you use iPhone: All models work with iPhone via Bluetooth, but the experience varies. The Zepp app (Amazfit and Xiaomi) tends to have better integration with iOS than Huawei Health. Check the minimum compatible iOS version in the technical sheet of the model you’re going to buy.

Imports, Anatel and warranty: what you need to know

Models imported from China through Mercado Livre or AliExpress may be cheaper, but come without Anatel approval (mandatory certification for wireless devices in Brazil) and without local warranty. In case of defect, the support process is more complicated and may require international shipping.

Xiaomi, Amazfit, Huawei and Redmi models have versions with Anatel approval sold by official distributors in Brazil. Always check the Anatel approval number on the box or product listing before purchasing. This ensures that the device has been tested for operation in national territory and that local technical support is available to you.

The standard manufacturer warranty in Brazil is 1 year, but can vary by sales channel. Buying from authorized resellers makes the process much easier in case of defect.

Frequently asked questions about smartwatches under R$ 500

Do cheap smartwatches monitor sleep well?

The models on this list use an accelerometer and heart rate to estimate sleep phases. It’s not equivalent to a clinical polysomnography exam, but it works well to identify sleep patterns and overall quality over time. The Amazfit and Xiaomi apps are the most detailed in this analysis, according to publicly available interfaces.

Is it worth importing to pay less?

It depends on the risk you accept. Without Anatel approval and without local warranty, any hardware problem means either disposal or international shipping. For those who understand the process and accept the risk, it can make sense. For most buyers, the small price difference is worth it for the peace of mind of local warranty.

Do these watches work without a phone nearby?

All record data locally, so you can go for a run without your phone. But notifications, synchronization and configuration adjustments depend on Bluetooth connection with the smartphone. Built-in GPS on models that have this feature works autonomously, without needing the phone nearby.

What’s the difference between AMOLED and LCD on a smartwatch?

AMOLED is a screen technology where each pixel emits its own light, resulting in deeper blacks, greater contrast and lower power consumption when displaying dark colors. LCD relies on constant backlight, which reduces contrast and generally consumes more battery. In practice, AMOLED screen on a smartwatch means better visibility in sunlight and watch faces with black background that help save battery.

What to bring to the store (or to the cart)

The best choice for most readers in 2026 is the Xiaomi Smart Band 10 Pro, for the balance between GPS, screen, software and price. If aesthetics matter more than screen size, the Amazfit GTR Mini is the most elegant alternative on the list. And if budget is the main factor, the Huawei Band 9 delivers the essentials for less than R$ 350.

Just as it happens when choosing components for a PC, like in the comparison of best GPU up to R$ 3,000 for gaming at 1080p in 2026, the key is to understand which specification has the most impact on your actual use before looking at the price. Smartwatch is no different: define whether GPS, battery or design is what matters most in your routine, and the choice becomes much simpler.
