Fitbit Charge 3 review: A better fitness tracker everywhere it counts

Smartwatches may still be getting a lot of hype, but there's still plenty to be said for a dedicated fitness tracker. 

While smartwatches may have health and fitness features of their own, a big part of their appeal is that they can also act as an extension of your smartphone. Fitness trackers on the other hand, like Fitbit's new Charge 3, put fitness first even though many models include some basic smartwatch features.

If that sounds appealing, then there's a lot to like about the Charge 3, which improves on the company's Charge 2 tracker in nearly every way.

The Charge 3 comes in two variations, the $149.95 Charge 3 and the $169.95 Charge 3 Special Edition. I reviewed the latter, but the only difference between the two are the bands that come in the box and the ability to make mobile payments.

But if you're trying to decide between the two, the bands alone might be enough to help you make up your mind. In addition to the standard black rubber sport band, the Special Edition comes with either a lavender woven band or a white sport band that resembles the Nike Sport bands for the Apple Watch. Those bands are only available for the Special Edition model, but Fitbit sells other, similar, bands à la carte as well. In any case, you'll save money by buying the extra bands bundled together with the Special Edition.

That alone makes it worth the extra twenty bucks for the Special Edition, in my opinion. If you're going to wear this every day, you're going to want to mix up your bands a bit, and the upgraded bands go a long way toward making the Charge 3 look and feel a little more elegant than the standard rubber band. (Fitbit also offers leather bands, which look and feel fantastic, but at $49.95 each, they're definitely on the pricey side.)

Better in the details

New band styles aside, Fitbit has improved the design of its newest tracker in subtle, but significant ways. The Charge 3 is even smaller and slimmer than 2016's Charge 2. The bands are much easier to swap out than the previous design, which, again, is an added bonus if you end up getting the Special Edition model 

It's also much more comfortable: the bands aren't as chunky, and the aluminum tracker has rounded edges on the back and sides so it hugs your wrist a bit better. Along with the new bands, this helps make the Charge 3 look and feel a bit less like a boxy fitness tracker.

The side button is no longer an actual button that protrudes from the side of the tracker. Instead, it's a small haptic "button" (similar to the home "button" on the iPhone 7) that sits flush against the side and vibrates a bit each time you touch it. The sensors on the back also sit flatter against the actual tracker compared with the Charge 2. 

On the front, the display is improved: It's now a full touchscreen, and it's more scratch resistant (the Charge 2 had screen you could tap on to navigate, but it couldn't recognize swipes and other gestures). The display is also noticeably brighter, which makes it easier to view in sunlight. 

Most importantly, though: the Charge 3 has far better battery life. It's rated up to a week, according to Fitbit, but I found I was sometimes able to squeeze even a bit more out of it. Either way, though, it's hard to overstate just how much of a difference this makes. One of the reasons I prefer fitness trackers over full-on smartwatches is precisely because having to remember to charge on a daily basis is a huge pain — particularly if you like to use your device to track your sleep at night. 

Fitness and health still come first

The Charge 3 may look a bit less like a traditional fitness tracker, but Fitbit hasn't skimped on the exercise-tracking or health features. You track more than a dozen different exercise types, many of which will kick in automatically when you start your workout.

You can also choose presets for your favorite exercises to make them more easily accessible from your wrist. These presets aren't new, but they've been upgraded; on the Charge 3, you can set specific goals for these exercises, like running a certain distance or lifting weights for a specific amount of time. When you reach the goal, the Fitbit vibrates and displays a little animation to "celebrate" you reaching your goal.

The Charge 3 is also waterproof, so you can use it to record your swims or take it along for a run or bike ride in the rain. 

On the health side, the Charge 3 comes with newly improved sleep tracking features. The tracker approximates your bedtime, wake-up time, and the various stages of your sleep cycle based on your heart rate and movement throughout the night. All this is broken down into a graph in the Fitbit app where you can see your sleep cycle over the course of each night.
