Now, let’s take a look at the newer wearable, to see what are the differences on appearance, heart rate monitor, new features, battery life, etc…

Fitbit Charge 2 Heart Rate + Fitness Wristband (US Version)


The first impression that is easily to be realized when you look at the Charge 2 device is that: Charge 2 has a larger LED monitor, compared to its older brother, Charge HR. This can be seen as an over expecting, since the band can display more information, means more interactive to the user. Fitbit still keep the left button that allow user to switch between categories of information, and the displaying can be customized via Fitbit app from your smart phone. Once a category is displayed via button pressing, you can slightly tab to the screen to access the more details.

Fitbit Charge HR Wireless Activity Wristband

The band seems to have no change in size, and replaceable band reminds to the recently version of Alta/Alta HR, with many options for user, depending on his style, regarding to the band color (black, plum, blue, coffee, teal, blush pink), materials (silicone, leather).

Heart Rate monitor.

Fitbit still use the two green led lights underneath to monitor the heart beat. The device can provide an exact measurement on your heart rate all day long.


By inheriting the feature of its older brother, Charge 2 is equipped with basic features such as: step count, distance calculation, calorie burned, and active minutes, remind to move, heart rate monitor, sleep tracking… Some more extra features that are available in Charge HR such as syncing to smart phone to notify when there is any new message, call, or time alert with silent vibrating, also including in the new one.

So, what are the things that make Charge 2 becomes more attractive? The first is Relax application, which will “provide personalized deep breathing session, that can help you find moments of calm throughout your day” as being introduced by Fitbit in only 2 versions of Blaze and Charge 2; the second, Charge 2 supports more sport activities, but the price of two mostly to be the same.

The GPS feature still depends on the smart phone. That means when you are doing workout, you have to bring your smart phone along, so that it can track your position, distance via the smart phone, then give more correct result of exercising.

Battery life.

Charge 2 has rechargeable battery with life span up to 5 or 6 days, depend on how you use it, and whether GPS is turned on or not.


With the equivalent price, there is no reason to make a choice of Charge 2 (compared to Charge HR), due to the remaining features, but including some more extras, and a very fashionable design.

But in the other hand, one thing that Fitbit seems to have no change is that the ability of waterproof, GPS still depend mostly on the smart phone, battery life span… and improvement in these factors may the things we can hope in some next Fitbit generation.
