Fitbit Charge 6 vs Xiaomi Smart Band 8 – Which One Should You Buy?

The Fitbit Charge 6 and Xiaomi Smart Band 8 are two of the most popular fitness trackers in 2025, offering strong health features, long battery life, and lightweight designs. But even though they look similar on the surface, the experience you get from each device is completely different. One focuses heavily on accurate health tracking and premium software, while the other gives maximum value at a budget-friendly price. Here is the full breakdown to help you decide which one fits your lifestyle better.

Design & Display

The Fitbit Charge 6 keeps a slim, rectangular design with a sharp AMOLED display that’s easy to read outdoors. It feels more like a fitness-first tracker rather than a smartwatch replacement. The aluminium body gives it a premium feel, and the strap is comfortable enough for all-day and overnight wear. The Xiaomi Smart Band 8 goes for a more playful, curved design with a larger display area and colourful interface. It also offers interchangeable straps and even a “pendant mode” where it can be worn as a necklace. Overall, Fitbit looks more professional and focused, while Xiaomi offers a more customisable and fun style.

Health & Fitness Tracking

Fitbit Charge 6 excels in accuracy and advanced health data. The continuous heart-rate monitoring is highly reliable, sleep tracking is detailed, and the watch integrates closely with Google Fit. You also get ECG, SpO2, stress tracking, guided breathing sessions, and workout auto-detection that works consistently. Fitbit’s algorithms still feel more polished and trustworthy for serious tracking.

The Xiaomi Smart Band 8 offers a huge list of features for the price. Heart-rate tracking, sleep analysis, SpO2, step count, stress monitoring, and more are included. The band supports over a hundred workout modes and gives daily readiness suggestions. While the data is good, it is not as consistently accurate as Fitbit, especially during intense workouts. However, for casual users, Xiaomi provides more than enough insights.

Battery Life

Battery performance is strong on both, but Xiaomi stretches farther. The Fitbit Charge 6 typically lasts around 6–7 days on normal use with health tracking active. It’s dependable and charges quickly. The Xiaomi Smart Band 8 goes further, often hitting 10–12 days depending on settings. If long battery life is a priority, Xiaomi delivers the better experience.

App Experience & Software

Fitbit offers one of the cleanest health apps available. The interface is simple, the graphs are easy to understand, and long-term trend reports are extremely helpful. The integration with Google services is improving, making syncing smoother and more reliable. Xiaomi’s app offers a large set of features but can feel a little more crowded. You get plenty of data, but the layout is less polished compared to Fitbit’s clean design. Both let you track workouts, view sleep history, and customise watch faces.

Smart Features

Fitbit Charge 6 has limited smartwatch features but enough for most users: notifications, music control, Google Maps navigation, and Google Wallet support. It’s designed primarily for health, not heavy app usage. The Xiaomi Smart Band 8 offers similar basic smart features, but without advanced integrations. It’s simple and functional, and users who just want lightweight smart notifications will find it more than enough.

Comfort & Daily Use

Both trackers are extremely comfortable for all-day wear. The Fitbit Charge 6 feels slightly more premium and secure on the wrist. Xiaomi’s lightweight design is flexible and barely noticeable during sleep or workouts. For running, the Fitbit tends to give more accurate readings, while Xiaomi gives a more relaxed, user-friendly experience.

Price & Value

Fitbit Charge 6 is the more premium option with a higher price point. You’re paying for accuracy, build quality, and a polished software ecosystem. The Xiaomi Smart Band 8, on the other hand, delivers outstanding value for its cost, offering many features for a fraction of the price. For budget-focused buyers, Xiaomi is unbeatable.

Final Verdict — Which One Should You Buy?

Choose the Fitbit Charge 6 if you want accurate health tracking, reliable sensors, polished software, and premium build quality. It’s the better choice for serious fitness users who care deeply about consistent data and long-term trends.
Choose the Xiaomi Smart Band 8 if you want maximum value, strong battery life, plenty of features, customisable designs, and a comfortable daily experience at a much lower price. It’s ideal for casual fitness users and anyone wanting a lightweight tracker that delivers more than expected for the cost.
Both are excellent choices, but your decision depends on whether you prefer premium accuracy or incredible value.
