Samsung Galaxy Fit 4 Fitness Band – specifications, features and details

Samsung Galaxy Fit 4 is a midrange fitness band designed for continuous health monitoring, daily activity logging, guided workouts, and smartphone notification management in a compact wrist worn format. Its 1.74 inch AMOLED panel delivers a 336 x 480 pixel resolution, approximately 336 pixels per inch, and up to 1,000 nits of peak brightness for improved outdoor legibility. The 220 mAh lithium polymer battery targets up to 13 days of typical use, while heavier use with continuous display functions, frequent measurements, and connected GPS activity can reduce practical endurance to about 7 days. At roughly 19 g without its strap, the band is positioned for day and night wear, including sleep tracking, and its 5 ATM plus IP68 protection supports pool swimming and routine exposure to dust and water. Samsung Health serves as the central data platform, and Samsung publishes ecosystem documentation, support material, and device compatibility information through samsung.com.

📝 Features and Analysis

📚 Glossary

• AMOLED: Active Matrix Organic Light Emitting Diode is a display technology in which each pixel emits its own light. Because black pixels can be switched off, AMOLED displays provide high contrast, deep blacks, vibrant color, and efficient power use when dark interface themes are used.
• PPG: Photoplethysmography is an optical measurement method. Green, red, and infrared light emitters illuminate the skin, while photodiodes examine changes in reflected light caused by blood volume changes in small vessels. Wearables use PPG to estimate heart rate, blood oxygen saturation, and some heart rate variability signals.
• HRV: Heart rate variability measures the changing time intervals between consecutive heartbeats. A higher or lower value is not independently a diagnosis, but longer term HRV trends can help a user understand recovery, sleep quality, training load, and physiological stress.
• 5 ATM: A 5 ATM rating indicates resistance to pressure equivalent to 50 m of static water. It is generally appropriate for surface swimming, rain, shower exposure, and shallow water activity. It does not make a band suitable for scuba diving, high pressure water sports, or repeated deep water use.
• Connected GPS: Connected GPS means the band receives location data from the GPS, Galileo, GLONASS, or BeiDou receiver in a paired smartphone. This design reduces device weight, cost, and battery consumption, but the phone must accompany the wearer to record a route accurately.
• IP68: IP68 is an ingress protection classification defined by IEC 60529. The first digit indicates dust protection and the second digit indicates water protection under defined test conditions. The rating complements, rather than replaces, the separate 5 ATM water resistance specification.

🆚 Comparison

Galaxy Fit 4 occupies the premium fitness band segment between inexpensive basic trackers and app rich smartwatches. Its technical profile emphasizes a large AMOLED display, low weight, 5 ATM durability, approximately two week typical battery performance, and Samsung Health data continuity. The main tradeoff is connected GPS rather than an onboard satellite receiver, a decision that supports a slimmer and lighter device but makes phone free outdoor route recording less convenient. Buyers should compare display size, positioning method, battery capacity, health application quality, notification behavior, and regional price rather than judging the category solely by exercise mode counts.

• Rival 1: Xiaomi Smart Band 9 Pro: Xiaomi’s close rival uses a similarly sized 1.74 inch AMOLED display and competes near the same EUR 79 class, but it includes an onboard GNSS receiver for phone free outdoor route tracking. Galaxy Fit 4 relies on connected GPS, while offering tighter Samsung Health synchronization, Galaxy phone camera controls, and more cohesive integration for owners of Samsung phones. Xiaomi is the stronger fit for runners who regularly leave a phone behind, whereas Galaxy Fit 4 is the stronger fit for users who value Samsung account continuity and synchronized health records.
• Rival 2: Huawei Band 9: Huawei Band 9 is a lightweight AMOLED fitness band that commonly sells below Galaxy Fit 4 and places a strong emphasis on sleep tracking and comfort. Galaxy Fit 4 targets a larger, brighter 1.74 inch display and a more extensive Galaxy ecosystem experience, while Huawei’s model is typically more compact and lighter. Neither product is intended to replace a cellular smartwatch, but Galaxy Fit 4 offers a more direct path into Samsung Health for Android users who already use Galaxy phones, earbuds, or health services.
