Check Current PriceKey Features of the Fitbit Charge
The Fitbit Charge comes packed with features designed to help you monitor and improve your health. From advanced heart rate tracking to built-in GPS functionality, this fitness tracker offers comprehensive monitoring capabilities in a compact form factor.
Heart Rate Monitoring
The Fitbit Charge features an optical heart rate sensor that continuously tracks your heart rate throughout the day. This provides valuable insights into your resting heart rate, workout intensity zones, and overall cardiovascular health. During testing, we found the heart rate monitoring to be reasonably accurate when compared to chest strap monitors, with only minor discrepancies during high-intensity workouts.
Built-in GPS
With built-in GPS functionality, the Fitbit Charge allows you to track your outdoor activities without needing to carry your phone. This feature maps your routes and provides detailed metrics on pace, distance, and elevation changes. The GPS connects quickly in most environments, though it may take slightly longer to establish a connection in dense urban areas or under heavy tree cover.
Sleep Tracking
The sleep tracking feature on the Fitbit Charge provides comprehensive insights into your sleep patterns, including sleep stages (light, deep, and REM), sleep score, and sleep schedule consistency. The device's comfortable design makes it easy to wear overnight, and the data collected helps you understand and improve your sleep quality over time.
Battery Life
One of the standout features of the Fitbit Charge is its impressive battery life. With up to 7 days of use on a single charge, it outperforms many competitors in the fitness tracker market. Actual battery performance may vary depending on usage patterns, with features like GPS and always-on display reducing overall battery life.
Water Resistance
The Fitbit Charge is water-resistant up to 50 meters, making it suitable for swimming, showering, and other water-based activities. This durability ensures you can wear your tracker throughout various daily activities without concern for water damage.
App Integration
The Fitbit app serves as the central hub for all your fitness data, offering intuitive dashboards, detailed analytics, and social features to connect with friends. The app is compatible with both iOS and Android devices, providing a seamless experience regardless of your smartphone preference.

Design & Comfort
The Fitbit Charge strikes a balance between functionality and aesthetics, with a design that's both practical for fitness tracking and stylish enough for everyday wear. The slim profile and lightweight construction make it comfortable for continuous use, including during sleep.
Materials & Build Quality
The Fitbit Charge features a combination of aluminum, glass, and silicone materials that create a premium feel while maintaining durability. The aluminum case provides structural integrity without adding excessive weight, while the glass screen offers good visibility and touch responsiveness. The standard silicone band is soft and flexible, making it comfortable for extended wear.
Screen Quality
The AMOLED touchscreen display on the Fitbit Charge delivers vibrant colors and sharp text, making it easy to read notifications and fitness data even in bright sunlight. The screen size strikes a good balance between visibility and device footprint, offering enough space to display important information without feeling bulky on the wrist.
Strap Options
While the Fitbit Charge comes with a standard silicone band, the quick-release mechanism makes it easy to swap bands for different occasions or preferences. Official Fitbit bands include sport, woven, and leather options, while third-party manufacturers offer an even wider variety of styles and materials. This versatility allows you to customize your tracker's appearance to match different outfits or activities.
Wearability
The lightweight design (approximately 15g) and contoured shape make the Fitbit Charge comfortable for all-day wear. The band sits flush against the wrist without digging in or causing irritation during movement. For sleep tracking, the low profile ensures it doesn't catch on bedding or feel intrusive while you rest. Some users with sensitive skin may experience minor irritation with the silicone band during sweaty activities, but this can be mitigated by periodic cleaning and occasional band removal.
Find Your Perfect Style
The Fitbit Charge offers multiple band options to match your personal style and comfort preferences.
View Band OptionsPerformance Analysis
The true value of any fitness tracker lies in its accuracy and reliability. We tested the Fitbit Charge against other leading devices to evaluate its performance across key tracking metrics.
Step Counting Accuracy
The Fitbit Charge uses a 3-axis accelerometer to track steps and movement. In our testing, it demonstrated approximately 97% accuracy when compared to manual counting during controlled walking tests. The device occasionally registers false steps during certain arm movements while stationary, but this is a common limitation across most wrist-based trackers. For everyday step tracking, the Fitbit Charge provides reliable data that effectively captures your overall activity level.
Heart Rate Data Precision
When compared to chest strap heart rate monitors (the gold standard for consumer heart rate tracking), the Fitbit Charge performs admirably. At rest and during moderate activity, the heart rate readings typically fall within 3-5 beats per minute of the reference device. During high-intensity interval training or activities with rapid heart rate changes, the discrepancy increases slightly, with delays in detecting quick spikes or drops in heart rate. This performance is consistent with most optical wrist-based sensors and provides sufficient accuracy for general fitness tracking purposes.
Sleep Tracking Capabilities
The sleep tracking functionality of the Fitbit Charge provides detailed insights into sleep stages, including light, deep, and REM sleep. When compared to consumer sleep tracking devices, the Fitbit Charge shows consistent patterns and reasonable accuracy in detecting sleep onset and wake times. While not as precise as medical-grade sleep monitoring equipment, it offers valuable data for identifying trends in your sleep quality and duration over time.
GPS Accuracy
The built-in GPS functionality tracks distance with approximately 95-98% accuracy compared to measured routes. In open areas with clear sky visibility, the GPS performance is excellent, with minimal deviation from actual routes. In urban environments with tall buildings or under dense tree cover, slight discrepancies may occur, but the overall tracking remains reliable for most outdoor activities.

Ideal for Casual Exercisers
If you're focused on general fitness improvement, step counting, and basic health monitoring, the Fitbit Charge offers everything you need in an intuitive package. The motivational features, move reminders, and social aspects of the Fitbit ecosystem make it excellent for maintaining consistent activity levels and gradually building healthier habits.
Suitable for Intermediate Athletes
For runners, cyclists, and gym-goers who want to track workouts without the bulk of a full smartwatch, the Fitbit Charge provides sufficient accuracy and features. The built-in GPS, heart rate monitoring, and exercise recognition cover most training needs, though serious athletes might eventually want more specialized devices.
Consider Alternatives If...
