Build Quality Assessment
The Fitbit Charge 2 design strikes an excellent balance between functionality and aesthetics. The elastomer band feels soft against the skin, making it suitable for 24/7 wear without causing irritation during sleep or exercise.
Our Fitbit Charge 2 comfort testing revealed that most users can wear this device continuously without discomfort. The lightweight design (38 grams) ensures it doesn’t feel bulky during sleep, which is crucial for accurate sleep tracking.
The OLED display, while not as bright as newer models, provides adequate visibility in most lighting conditions. The single button interface is intuitive and responsive, though it may take some getting used to for first-time fitness tracker users.
Sleep Tracking Performance
Our comprehensive Fitbit Charge 2 sleep tracking analysis reveals impressive performance for a device in this price range. The automatic sleep detection works reliably, typically recognizing sleep onset within 10-15 minutes of actual bedtime.
The Fitbit Charge 2 sleep monitor provides detailed insights into light, deep, and REM sleep stages. While not as sophisticated as newer models with SpO2 sensors, it offers valuable baseline sleep data that most users find helpful for understanding their sleep patterns.
