It is recommended to charge the device every few days to ensure the device is working at its maximum capacity and is always tracking. The watch will save daily totals for the past month and measure heart rate every second. 

Material 

The watch itself is 3.5 cm long by 2.3 cm wide and 1.3 cm high. A nice small size that is not cumbersome on the wrist during a workout. It is a flexible and durable material that is similar to other sports watches. 

The band comes in two sizes, small and large. The small is meant to fit wrists 14 cm to 18 cm. The large is meant to fit wrists 18 cm to 22.1 cm. 

With the material being what it is, it is water-resistant up to 50 meters. This does not include hot tubs and saunas. Its optimal operating temperature is -20 degrees to 150 degrees Celsius. 

Fitbit Price 

Charge 4 has a starting price of $149.95. That is for the black, rosewood, or storm blue wristband. If you want to get the special edition granite reflective or the black woven band, then you are going to pay $169.95.

Design 

The Fitbit Charge 4 comes with a plastic resin casing and the band has a stainless steel buckle. The watch band comes in 5 different colours. Available colours include Black, Rosewood, Storm Blue, Granite, Reflective Woven. 

To turn on the device you can either tap the touch screen, shake your wrist gently, or by pressing the button on the left side of the device. That button on the left side of the device is also going to be how you navigate between the different applications within the watch. 

The screen itself measures 0.72 inches diagonally across the screen. The resolution is 128-by-72 pixels. It has a monochrome OLED display. The display is sharp and bright. 

Smartwatch Capabilities 

The Fitbit Charge 4 does not only have a slew of fitness capabilities. Charge 4 is also equipped with applications such as Spotify, Fitbit Pay, and smartphone notifications. 

You can now be logged into your Spotify account from your Fitbit Charge 4 so you can listen to your favourite music while working out. The controls let you play, shuffle, and even like songs. 

Fitbit Pay links your credit cards to your watch so that you can pay with just a flick of the wrist. This application works with Chase, Wells Fargo, Bank of America, Capital One, and other card issuers

Sleep Tracking 

One of the biggest upgrades of the Fitbit Charge 4 is the new sleep tracking capabilities. 

With the Fitbit Charge 4, you can now track the time that you spend in the different sleep cycles. There is also a sleep mode which allows the screen display to dim as well as silence incoming notifications at night. 

After your night of sleep, you will be able to see a wealth of information. Displayed is information about, the amount of time you slept, how your heart rate fluctuates during your sleep, and sleep stages. 

Each morning you will also get a sleep score. This score is based on the amount of time that you spent asleep and how much REM sleep you got. The higher the score, the better your sleep quality. 

This is a nice snapshot to compare your sleep tracking data. 

Fitness Capabilities 

One of the biggest aspects of Charge 4 is the ability to track your fitness and exercise. 

A great new addition to the Fitbit Charge 4 is a goal-based exercise. Goal-based exercise allows you to set a metric such as time, calories, or distance. Then once you reach that goal, your Fitbit will alert you. So rather than checking your watch constantly, you can know that you will be alerted. 

The watch also tracks things such as heart rate. You will receive data about your heart rate zone, beats per minute, and resting heart rate. This allows you to adjust your workout accordingly. 

GPS 

Previously the Fitbit required you to use a smartphone if you wanted a GPS. This caused some issues with accuracy. With this series, the watch can do it on its own. 

The default sports that are tracked with the Charge 4 GPS are running, biking, swimming, walking, outdoor hiking or workouts, and also the treadmill. GPS can track distance, pace, speed, and more. 

You will be able to see the map of your route in the Fitbit app once you have completed the workout. 

 

Fitbit Charge 4 Reviews 

Overall, the Fitbit Charge 4 has received good reviews. Additions such as the GPS function, the Spotify capabilities, sleep tools, and the Fitbit Pay, make this watch well worth the money.

While the screen and interface are relatively basic and there were no updates to the body of the watch from Charge 3, it is still a quality purchase.

Pros of the Fitbit Charge 4

The built-in GPS and motivating active zone minutes metrics are a big highlight to note in the Fitbit Charge 4. 

There are also more sleep-tracking tools and even more companion apps than other watches. Fitbit Charge 4 has improved the basic functions that you need for fitness tracking. 

The heart rate monitor is also a valuable and reliable piece of Charge 4 that gives you a better picture of your fitness level. 

Cons of the Fitbit Charge 4 

If you are a fan of colour, this watch may not be for you. While you can customize the design of the display, it will still not be in colour. It is also a more basic interface. So if you are looking for something with more bells and whistles this is not the watch for you. 

Speaking of the screen, using the screens wake function is known to be finicky. This is the function that allows you to shake your wrist to turn the screen on. The scene is also said to be slightly small. There is a large outer bezel on the sides.
