Fitbit has gained massive success in the fitness tracking và wearable communities by offering chất lượng products at affordable price points, & perhaps that’s why the Fitbit Charge HR was so successful. With a long-lasting battery, accurate activity tracking, và an easy-to-use companion app, the Charge HR was much more than just a glorified pedometer. It wasn’t all that attractive, though, and still very much looked like a standard fitness tracker.

A newer version of this device is now available. The Fitbit Charge 4 is the follow-up lớn the Charge 3, which itself is the follow-up khổng lồ the Charge 2. In 2021, you should only consider buying the Fitbit Charge 4. Trust us — it's far better than the Charge 2. Kiểm tra out our full reviews to learn more about the Fitbit Charge 4.
Review notes: I've been using the Fitbit Charge 2 as my main fitness tracker for 17 days. The Nexus 6P has been my điện thoại companion of choice for the duration of this review.

Prior to lớn 2016, Fitbit had a design problem. It wasn’t that the Charge HR, Surge, or Flex looked ugly, per se, they just looked like every other fitness tracker out there. Then at the beginning of 2016, the company launched two new fashion-focused devices, the Alta & the Blaze, which marked somewhat of a turning point for the company. Fitbit started using more high-quality materials like stainless steel in its devices, and that’s especially true for its latest fitness tracker.


*

The Charge 2, lượt thích the Alta before it, sports a stainless steel chassis & a big, tap-enabled display. You’ll find one button on the left side of the device which is used for cycling through different modes và functions. Tapping the button will allow you to cycle through the current time, heart rate, activity start, stopwatch, relaxation timer, & active silent alarms. You can remove any of these & reorder them all from within the Fitbit companion app. Alternatively, you can tap on the display to cycle through your daily stats, which include steps taken, heart rate, distance traveled, calories burned, stairs climbed, & active minutes.

This new, larger display is certainly a welcome addition, as it not only allows for more information to lớn be shown on one screen but also for more unique clock faces. There are quite a few to choose from — seven to be exact — and they all offer a good mixture of style & functionality.


A bigger display also means there’s more room for điện thoại thông minh notifications. While the Charge HR was only able to lớn provide call notifications, the Charge 2 supports call, text, & calendar events. The display isn’t actually that big, though, so notifications are sometimes difficult to read.

One of my main gripes with the Charge HR was that the display scratched pretty easily, & I’m happy lớn say that issue has been fixed this time around. I’ve been using the Charge 2 for a few weeks now, & we still have yet to lớn see any scratches on this thing.

Another major thiết kế change you’ll notice with the Charge 2 is tư vấn for interchangeable bands. The Charge 2 is offered in Black, Blue, Plum, & Teal color options, as well as Special Edition Lavender/Rose Gold and Black/Gunmetal colors. You can buy any of these bands separately from Fitbit’s trang web for $29.95 each. You can also opt for a fancier leather band in Brown, Blush Pink, or Indigo if you don’t mind shelling out an extra $69.95.

As is par for the course of most fitness trackers in this price range, the Fitbit Charge 2 will track your steps taken, distance traveled, calories burned, floors climbed, active minutes, & sleep. You’ll notice we didn’t mention swim tracking, though, & that’s because this device won’t survive in water. Yet again, Fitbit decided khổng lồ forego proper waterproofing on its flagship fitness tracker, which we must say is a tad upsetting at this point. Fitbit has long been an innovator in the fitness tracking world, but the company is extremely behind in this area. Garmin, Withings, Xiaomi, và most of Fitbit’s other direct competitors have managed khổng lồ launch fitness trackers with decent waterproof ratings, so it’s a shame lớn see the Charge 2 thể thao a “splash proof” rating.


Fitbit did launch its very first waterproof fitness tracker, the Flex 2, at the same time as the Charge 2.

When comparing them against one another, we found that both the Charge 2 and Charge HR are basically on par with one another in terms of step tracking, with each one being just a handful of steps off from one another after a run or walk. We also took the Charge 2, Charge HR, & Garmin Vivoactive HR out on a walk for 500 steps, and all three came back within four steps of each other.


Floors climbed và active minutes metrics are pretty much spot on as well, but unfortunately, since the Charge 2 doesn’t have GPS onboard distance metrics won’t be all that accurate. It does have connected GPS, which allows you to use your phone’s GPS lớn get more accurate distance tracking và pace results. That of course means you’ll have khổng lồ carry your phone with you when you’re exercising, which isn’t all that convenient for most people.


Like most recent Fitbit devices, the Charge 2 comes with Fitbit’s PurePulse optical heart rate monitor, which will help you keep track of your active và resting heart rate. We’ve been very impressed with the Charge 2’s resting heart rate readings, though active readings, unsurprisingly, can be a little off at times. We tested the PurePulse heart rate monitor against the Wahoo Tickr X chest strap on multiple occasions, and much of the time, the PurePulse sensor came up short by about 5bpm or so.


Below you’ll find screenshots of the Wahoo Tickr X vs the Fitbit Charge 2 during the same run. Note the difference between the peak heart rate readings on the Tickr X (towards the over of the workout) & the Charge 2’s readings at the same point. The Tickr X recorded a peak reading of ~176bpm, while the Charge 2 was only recording ~130bpm at this point.


One of the best things about using Fitbit devices is the company’s powerful automatic activity tracking software, or SmartTrack. The Fitbit Charge 2 is able lớn track walking, running, outdoor biking, & elliptical workouts automatically, và will categorize each of those into groups: thể thao (high-intensity movement activities lượt thích basketball và soccer) và Aerobic Workouts (Zumba, cardio-kickboxing, etc). SmartTrack is normally very impressive when it comes to recognizing which activities you’re doing, but we’d still recommend starting a workout manually if you can remember. Automatically tracked workouts won’t track distance or pace, for instance.


In the screenshots below, you can see the screens labeled “Bike” are workouts where I started my activity manually from the tracker, & the screen labeled “Outdoor Bike” is the activity tracked by SmartTrack.


Speaking of automatic activity recognition, the Fitbit Charge 2 will automatically track your sleep every night. There’s no need khổng lồ tap any “sleep now” button or anything before you hit the hay. Just make sure you fall asleep while you’re wearing your Fitbit, & it’ll have sleep stats waiting for you in the morning. The Charge 2 can record your total sleep time and sleep quality, which is measured by the number of times you woke up and how many times you became restless throughout the night. Overall, we’ve found the Charge 2 to be quite accurate on the sleep tracking front, with no glaring errors as far as we can tell. The tracker also supports silent alarms, which is always nice to see on wrist-mounted fitness wearables.

Fitbit also introduced a few new features to lớn the Charge 2 that should help users stay healthy và relaxed over time. The first of these new features is a measurement of your Cardio Fitness Level. Found within the heart rate section of the Fitbit app, a personalized score based on an estimation of your VO2 max (how well your body uses oxygen when you’re working out the hardest) will give you a rating on your overall cardiovascular fitness. Estimated VO2 Max is pretty much the gold standard for grading cardiovascular fitness. Basically, the higher your VO2 Max & Cardio Fitness Score, the better your cardiovascular fitness.


While the Cardio Fitness Score will certainly help some folks make improvements to lớn their workouts in the long run, the feature is kind of tucked away in the heart rate portion of the Fitbit app. You won’t find it on the trang chủ screen of the Fitbit app (aka Dashboard), & unless you were really exploring around the app you probably wouldn’t come across it. It’s just an odd place lớn put a big new feature, we suppose.


One other new feature present on the Charge 2 is on-device guided breathing. Fitbit calls this Relax. Once you navigate lớn Relax on your Charge 2, your device will begin walking you through two- lớn five-minute breathing exercises that should help you reduce stress, lessen anxiety, and lower blood pressure. Each breathing session is powered by Fitbit’s PurePulse heart rate monitor, of course. It uses your real-time heart rate stats khổng lồ measure your heart rate variability và determine the best breathing rate to suit your needs. Do we think this is a game-changing new feature? Not really, but the option is there if you need help calming down from time lớn time.


Fitbit claims the Charge 2 can last up khổng lồ five days on a single charge, & we’ve found that khổng lồ be somewhat true. With moderate usage và the heart rate monitor set khổng lồ automatic, we were only able lớn achieve a little over four days of battery life. It’s entirely possible khổng lồ make it last an extra day with the heart rate monitor turned off, but you should expect less than that if you’re wanting to record your heart rate.

As far as charging is concerned, we much prefer this method over the Charge HR’s tiny charging cable. With the Charge 2, just clasp the charger around the device’s chassis, plug it into a USB outlet, & you’re all set. There’s even a little hole in the clasp lớn fit around the Charge 2’s physical button so you know which way lớn put it on.
