Indeed, over a few runs ranging from 22 minutes to 49 minutes in length, the difference in average heart rate was around 3bpm.

The Fitbit app then helps you understand the factors that affect your stress levels, and take steps to manage it. The app then begins setting up your Charge 4 and installing software updates if they’re available, which for me took more than an hour. Active Zone Minutes considers the intensity of your exercises, not just the duration, which means it can be a much more effective metric for people who are attempting to stay fit. In testing, I sometimes had to tap the screen several times to get it to wake up, which can be annoying.The Charge 4 now also features a smart wake feature, which attempts to wake you up at the optimal time to ensure you’re feeling recharged and not groggy. Thanks to its fine Velcro fastener, you can easily adjust the bracelet to fit your wrist comfortably. Thanks to the Charge 4’s GPS, you can leave your phone at home and see your real-time pace and distance on your wrist. For my run/walk, the map showed that I reached cardio zone shortly after heading out, then alternated between fat burn, cardio, and peak zones for the rest of the time. One change I was pleasantly surprised with on the Charge 5 is the updated design of the silicone strap, as well as a softer material, there is a clever “infinity” closure which is a hole for your strap to be tucked into after you’ve adjusted the size to fit, making it super sleek and snug against your wrist.

If you would like your activity tracker to look more like a classic watch then the Fitbit Charge 4 metal straps are the ones you are looking for. The Charge 4 has a plastic case with an angular design and a dark color scheme (black, dark blue, and deep purple). com is a leading authority on technology, delivering lab-based, independent reviews of the latest products and services. The Fitbit Charge 4 can track six activities, but you can only create shortcuts for four on the device itself so you’ll need to pick and choose the ones you use more frequently. By monitoring your Active Zone Minutes, heart rate, and sleep, you'll get a range of insights and can set your own personal challenges.There were a few areas in a more remote part of town that the GPS would veer off to the side of the road a bit (or show me running down the side of a river), but nothing that would lead me to believe my GPS stats would be too inaccurate. The Charge 4 does almost everything right, but it’s just not the breath of fresh air the original Versa was. For example, if you're well rested and have lots of energy, the app may suggest a tough run, but if you're more tired it might suggest you try some active recovery with a gentle yoga session. The Fitbit Charge 5 is the latest model and is a very impressive fitness tracker, but its predecessor, the Fitbit Charge 4, might be better suited to your needs – particularly if you're on a tight budget.

Those with smaller wrists may also find there's a gap at the edges, where the Charge 4 connects to its strap; when my wife tried on the Charge 4, this gap was noticeable, though the device was secure. The Fitbit Charge 4 has a very similar design to its predecessor in terms of shape and size, with the slim, rectangular face we've come to expect.The special edition Charge 4 comes with a really nice woven strap (in addition to the classic straps) made from recycled materials. It’s certainly nice to be rewarded for how hard you exercise rather than just for how many steps you take or how long your workouts last. I’ve been testing my device pretty hard over the course of this review, so my battery life has been somewhere between five and six days.

That means you can’t go back to the Spotify app to control your music, or even the clock face to see the time, unless you end your workout. Like most other Fitbits, the Charge 4 will provide a sleep score from 1-100 based on your heart rate, time awake, and sleep stages (light, deep, and REM). We'd hoped that this iteration of the Fitbit might have a color screen, but it's still black and white.Each morning, this tells you how energized and well recovered you are, based on your sleep, recent activity, and heart rate variability. From there, just follow the instructions in the app to pair it with your phone via Bluetooth and enable notifications. Although I only spent 23 minutes in the Cardio and Peak zones (136 bpm and higher), I was awarded 46 minutes of credit.
