Fitbit continues its penchant for making very good wearables with the Charge 5 activity tracker fitness band, which finally shows some colour.

The Charge 5 marks Fitbit’s design shift in using a colour screen, bringing its activity trackers closer to its smartwatches. It also bridges a functional gap between them when it comes to what it can track. These two elements combine to make this device what it is, but in the end, it also leaves you with a choice to make.

Fitbit Charge 5 design

The colour AMOLED touchscreen changes so much of how the Charge 5 looks and feels. Fitbit previously removed buttons, but it’s touch-only to navigate now. This is actually carrying over from the Luxe, Fitbit’s more recent tracker, though the rubberized strap isn’t dramatically different from past Charge models.

If you’re used to swipe gestures from your iPhone or Android phone, you will learn how it works here. The mix of taps and swipes makes sense once you learn them, especially because the missing buttons open other opportunities. I just didn’t like that it often took more than one swipe to move across the interface.

The sides now have sensors with cool features like the electrocardiogram (ECG) and electrodermal activity (EDA) sensor to gauge stress. That also includes other familiar features we’ve come to know from Fitbit, like a heart rate monitor underneath and SpO2 sensor (for blood oxygen levels). That latter one is interesting because it originally appeared in the Fitbit Sense smartwatch, but you don’t get a skin temperature sensor. The Sense remains the only current Fitbit device with it, where it reads temperature fluctuations in your skin to tell if you’re too high or low within your range.

You also don’t get other smartwatch perks, like voice assistant integration with Alexa and Google Assistant. Not to mention a way to control music playback. Fitbit didn’t see to it to include neat features, like Spotify integration or just basic playback controls.

You do get built-in GPS for much better tracking outdoors, knowing your route when walking, running, hiking or cycling. One drawback is that without an altimeter, you can’t get any data related to elevation, so if you plan to climb or hike a mountain, the Charge 5 won’t tell you the heights you reach.

Setup and features of the Charge 5 

Despite the familiar look, the Charge 5 moves on from the previous strap design. If you have straps for the Charge 4 (and earlier), you won’t be able to use them here. The Charge 5 uses a different clipping mechanism incompatible with previous models. While I didn’t get a chance to try out other straps this time, they are available in various materials, like silicone, fabric, leather and metal.

It’s easy to set up the Charge 5 through the iOS or Android app, regardless of whether you’re new to Fitbit or replacing an older unit. Certain features, like the ECG, need to activate before you get started, though that’s also simple to do. The colour screen changes up the watch faces, with some nice options to select from.

Previous features, like Active Zone Minutes and the sleep tracking all apply here, as does your Daily Readiness score. Fitbit’s app grew a fair bit over the years, and it shows with its features, though some of that only comes by subscribing to Fitbit Premium.

A consequence of being activity tracker is that apps aren’t always optimized. Or even available, for that matter. Unlike the Sense or Versa watches, the Charge 5 is essentially limited to what Fitbit provides for it. You get your basics, like apps for exercise, alarms, timers, SpO2, ECG, EDA Scan and notifications, and that’s about it.

You can also set up the Charge 5 with Fitbit Pay to use it instead of your card at point-of-sale. It’s still very limited in Canada, with only Vancouver’s transit service and a handful of financial institutions supporting it, all of which stick to credit cards as the only option. While this feature is far more useful in the United States, it’s got a long way to go in Canada.

Tracking different things

Ironically, the Charge 5 isn’t all that different from its predecessors when it comes to tracking exercise. You can keep up to six as shortcuts, and swap them out between 16 others. Swipe to one on the tracker and start a session with goals, including heart zone notifications, and Active Zone Minutes. You can choose to turn GPS on or off to track route and distance, as well as leave the screen on at all times to see what it’s tracking while active.

It’s pretty much the same in practice compared to previous Fitbit devices, and much happens passively on top. Except that passive stuff needs to work in the right circumstances. And in some cases, you need to actually trigger it.

For example, the EDA sensor has you place your index finger and thumb on the sides for three minutes to read your response. You can do longer scans if you want, but as I noted when I reviewed the Sense, I found the feature worked best with those feeling some stress, anxiety or apprehension. It needs a good five scans just to get a read on you, though 20 is the magic number to tell you whether you’re stressed or not.

To do that, it tallies up a Stress Management score that also brings in activity and sleep data from the Charge 5 to come up with a number. While not required, you could try the Relax app’s breathing exercises, except they’re not available for some odd reason. At least they weren’t on my review unit. As a Premium subscriber, however, I had plenty of breathing and meditation routines I could try out, but as is, there wasn’t anything on the device itself to use.

Health tracking with the Fitbit Charge 5

The ECG was a long time coming for Fitbit. While other markets were able to use it on select Fitbit models, Canada lagged behind. Well, not anymore, as the feature runs perfectly fine on the Charge 5. Place your index finger and thumb on the sides for 30 seconds and the ECG app reads your heart rate looking for anything irregular, like an atrial fibrillation. I must stress that this isn’t a replacement nor a stand-in for a proper medical device. I think of it more as an early warning system in case there is something off. Plus, you can always show your doctor the data on the Fitbit app for further assessment.

Anyone with a pre-existing heart condition would surely appreciate having such a handy tool on their wrist. I also see it the same way with the EDA sensor, which did little for me, personally, though I can totally recognize how someone with anxiety might like keeping track of things like that.

The SpO2 sensor works the same as it has on other devices in that it estimates blood oxygen saturation, particularly during sleep. Often times, poor sleep may correlate with a lower SpO2 score, though that’s not always true. Either way, the feature is useful, except that the richer data falls within the Premium subscription. You can still see your sleep score, but you do have to subscribe to get more holistic data.

That brings me back to the Daily Readiness Score. This is every bit an umbrella over your activity (or lack thereof), and could provide interesting food for thought. To get the most out of it, wear the Charge 5 for four days and nights to get started. And then at least 14 days to truly get things going. It at least gives you a clue as to whether your body is up for an active workout or needs time to relax. Again, the Charge 5 can’t predict how you actually feel. But the data may tell you something you hadn’t considered, like not getting enough sleep, as one example.

Health Metrics is another good section within the app. It shows graphs for breathing rate, heart rate variability, skin temperature, oxygen saturation and resting heart rate.

Integration with your phone

I did miss music playback controls wearing the Charge 5, but at least it’s not totally independent of the phone. It can see notifications come in, like an incoming call or text message. You can send a quick reply if you use an Android phone, whereas you can only see the messages if you have an iPhone.

I mentioned there are no apps, and that’s another big difference with smartwatches. If you were looking to have a Starbucks app on here, that’s not happening. Other than watch faces, you won’t be adding much to this tracker.

Charge 5 battery life

Fitbit claims the Charge 5 can last up to seven days per charge, but that really depends. The biggest factor is the display. If you always leave it on, you will see battery life drop down to around two or three days. GPS is also a big factor in both directions. Use it often when exercising, and the battery precipitously drops. You can still toggle it on or off from each exercise on the device itself, but it’s just as easy to forget to do it.

Final thoughts on the Fitbit Charge 5 

Fitbit conducted a voluntary study in 2020, starting with the Charge 4, that looked to find out if its wearable devices could help detect the onset of infectious diseases in light of the COVID-19 pandemic. You can see the results for that here.

The Charge 5 sets up Fitbit to embrace colour displays and advanced sensory technology in its activity trackers. From here on in, the line between the company’s smartwatches and trackers will increasingly blur. You get an ECG, EDA and all the tracking that comes with Fitbit’s app. You do get way more insight as a Premium subscriber, but as always, you don’t always get context. The ‘why’ over a particular metric or result. Fitbit can’t really tell you right now, which is why I see this as more of a warning system rather than any form of medical care on your wrist. Use it to track exercise and wellness, and you should come away happy with how it does those things.

The Fitbit Charge 5 is available now in black, white and steel blue. All come with large and small size bands in the box.

I’m a fortunate man in being able to do the fun job of following and reporting on one of the most exciting industries in the world today. In my time covering consumer tech, I’ve written for a number of publications, including the Globe and Mail, Yahoo! Canada,, Canoe, Digital Trends, MobileSyrup, G4 Tech, PC World, Faze and AppStorm. I’ve also appeared on TV as a tech expert for Global, CTV and the Shopping Channel.


  1. This product sucks, it’s a glorified pulse monitor. It’s so confusing to use and frankly I wish I never bought it.

  2. As someone with heart concerns, I like the extra health tracking I could do with the ECG and heart rate tracker.

  3. I like how it should you when you need rest and when you shouldn’t. It would help me focus a little on my instead of my kids all the time. And be a healthier more active me. The gps would also help me not get lost like my husband always tells me I do.
    Thanks for opportunity.

  4. Stress Management score would be great to help prompt me to eat (tend to get hangry), be more mindful, connect with a friend for a laugh, take a break or do something to take care of myself. Also would be interesting and useful to track weekly and monthly stress patterns.

  5. The feature that I like the most in the Fitbit Charge 5 is the GPS because with it, I’m not afraid to explore!

  6. The feature I like the best on the Fitbit Charge 5 is the built-in GPS – I like the fact that it knows my route when walking, running, hiking or cycling. It would be very useful for monitoring my progress on well-traveled routes.

  7. My favourite function has to be the heart monitoring, ECG and blood oxygen monitoring. It’s amazing that you cam really have that just on your wrist.

  8. Love Fitbit and have been using one for years (fav feature on it is the sleep tracker). Screen is starting to get harder to read though so would appreciate the Charge 5 colour AMOLED touchscreen!

  9. I love the EDA feature because most of us are living with chronic Daily stress and to be able to self monitor and make changes to one’s lifestyle based on one’s readings is inspiring.

  10. The Fitbit’s colour screen is my best feature cause at my age now, the old eyes need as much pop & clarity as they can get.

  11. I like the SpO2 sensor feature the best. I have always wanted to know what my blood oxygen levels are since I have limited lung function and it would also come in handy for knowing if one needs to go to the hospital because the levels are too low in the case of COVID.

  12. I”ve never had a smart watch so I like the health functions like ECG to monitor your heart, also the co2 level in your blood.
