Feature-by-Feature Breakdown
Display & Screen
- Fitbit Blaze: Features a vibrant color touchscreen display that is larger and more visually appealing than the Charge HR. It offers better readability in various lighting conditions and a more smartwatch-like experience for notifications and app interaction. However, the larger screen can consume more battery.
- Hr Charge: Has a monochrome OLED display which is functional for displaying time, stats, and notifications but lacks the visual richness of the Blaze. It’s less power-hungry and very clear in direct sunlight. The smaller screen size can feel cramped for detailed information.
- Winner: fitbit blaze
Design & Build Quality
- Fitbit Blaze: Boasts a more modern and modular design with a removable tracker that can be placed in different stylish frames and bands. This offers greater customization and a more premium feel. The build is generally robust, but the modularity could be a point of failure for some.
- Hr Charge: Features a more traditional, integrated wristband design. It’s sleek and comfortable for all-day wear, often preferred for its simplicity and unobtrusiveness. The integrated design means less customization but also fewer potential points of detachment.

GPS & Workout Tracking
- Fitbit Blaze: While it doesn’t have built-in GPS, it uses “Connected GPS” which leverages your phone’s GPS to track pace and distance. It offers multi-sport modes and guided workouts via the Fitbit Coach app. The reliance on a phone for GPS can be a drawback for some users.
- Hr Charge: Lacks built-in GPS and connected GPS functionality. It relies on its accelerometer for distance and step tracking, which is less accurate for outdoor runs and cycling compared to GPS. Its workout tracking is more basic, focusing on heart rate and duration.
- Winner: fitbit blaze
Heart Rate Monitoring
- Fitbit Blaze: Features continuous PurePulse heart rate monitoring, providing insights into resting heart rate, heart rate zones during exercise, and calorie burn. The accuracy is generally good for a wrist-based sensor.
- Hr Charge: Was one of Fitbit’s first devices with continuous heart rate monitoring. It effectively tracks heart rate zones and calorie burn, offering valuable data for training. Accuracy is comparable to the Blaze for general use.
- Winner: Tie
Battery Life
- Fitbit Blaze: Typically offers around 5 days of battery life on a single charge. This is decent for a smartwatch with a color display, but less than many dedicated fitness trackers.
- Hr Charge: Known for its impressive battery life, often lasting 7 days or more on a single charge. This makes it a more convenient option for those who prefer not to charge frequently.
- Winner: hr charge
App Ecosystem & Integration

Fitbit Blaze Vs Hr Charge Buying Guide
Durability and Design
The Fitbit Blaze boasts a more robust and watch-like design, featuring a durable aluminum casing and a vibrant touchscreen display. Its interchangeable bands offer significant customization, allowing users to match their style or activity. While it can withstand splashes and sweat, it’s not ideal for intense swimming. The Charge HR, in contrast, has a more discreet, band-style form factor, prioritizing comfort and a lower profile for everyday wear. (See Also: Demeyere 5 Plus Vs Atlantis )
Fitness Tracking Features
Both devices excel at core fitness tracking, including step counting, distance, calories burned, and sleep monitoring. The Charge HR uniquely integrates continuous heart rate monitoring directly into its design, offering more precise calorie burn calculations and insights into heart rate zones during workouts. The Blaze also offers heart rate tracking but relies on its connected GPS for more advanced outdoor activity metrics, whereas the Charge HR has built-in GPS.
Smartwatch Capabilities and Display
The Fitbit Blaze leans more towards smartwatch functionality with its larger, color touchscreen. It allows for on-screen notifications for calls, texts, and calendar events, and offers music control directly from the wrist. The Charge HR provides simpler call and text alerts but lacks the advanced display and interactive features of the Blaze. For users prioritizing a more integrated smart experience beyond basic fitness, the Blaze is the clear contender.
Battery Life and Connectivity
Battery life is a key consideration for any wearable. The Fitbit Blaze typically offers around 5 days of battery life on a single charge, which is respectable given its more advanced display and features. The Fitbit Charge HR often provides a slightly longer battery life, sometimes reaching up to 7 days, due to its more minimalist display and fewer power-intensive functions. Both devices connect seamlessly to the Fitbit app via Bluetooth for data syncing and analysis. (See Also: Nikon 50 1 8 Vs 1 4 )

Frequently Asked Questions
Which Fitbit is better for swimming?
Neither the Fitbit Blaze nor the Charge HR are designed for swimming. While they are generally water-resistant for sweat and splashes, they lack the waterproofing needed for extended submersion. For swimming tracking, you would need to consider Fitbit models like the Flex 2 or Ionic, which are specifically rated for pool use.
Does the Blaze have built-in GPS?
No, the Fitbit Blaze does not have built-in GPS. It utilizes Connected GPS, meaning it uses the GPS signal from your paired smartphone to track outdoor activities like running and cycling. The Charge HR, however, does feature built-in GPS, allowing for accurate tracking of outdoor workouts without needing your phone.
Is the Charge HR’s heart rate monitor accurate?
The Charge HR’s PurePulse heart rate monitoring is generally considered accurate for continuous tracking during everyday activities and general workouts. However, like most wrist-based optical heart rate sensors, it can sometimes be less precise during high-intensity interval training or activities with a lot of wrist flexion, where the Blaze’s sensor might offer slightly more consistent readings.

Can I change the bands on the Blaze?
Yes, one of the key advantages of the Fitbit Blaze is its interchangeable band system. It uses a quick-release mechanism, allowing you to easily swap out the default sport band for a variety of other official Fitbit bands made from different materials like leather or stainless steel, as well as third-party options, enabling significant personalization.
Which is better for sleep tracking?
Both devices offer comprehensive sleep tracking, analyzing duration, deep sleep, light sleep, and awake times. The accuracy of sleep tracking is largely similar between the two as it relies on motion and heart rate data. The Charge HR’s continuous heart rate monitoring might offer slightly more nuanced data points for sleep stages, but the difference is usually minimal for most users.
Final Verdict
The Fitbit Blaze offers a more modern smartwatch experience with its vibrant color display, music controls, and on-screen notifications, making it ideal for those who want more than just fitness tracking. However, the Fitbit Charge HR excels in its dedicated heart rate monitoring and built-in GPS, providing more precise fitness data for serious athletes and a longer battery life in a simpler, more discreet package. If raw fitness tracking and battery are paramount, the Charge HR shines. For a blend of fitness and smart features, the Blaze takes the lead.
