Fitbit Charge 4 Review and technical details

Fitbit Charge 4 Review

Fitness trackers are becoming increasingly popular as more people are getting serious about daily workouts. And for quite some time, Fitbit has remained in the top position in offering affordable trackers. This time they have launched the Fitbit Charge 4, which has a number of improvements over the last-gen model.

Their latest offering has over 40,000+ ratings on Amazon and is currently the best Fitness tracker for around $140. Read our full review to see if it’s worth your money. Also, if you are interested in exercise bikes, read our review on the Cyclace Exercise Bike Stationary.

Added feature with no compromise on price

The design of the Fitbit Charge 4 hasn’t changed much from the previous iteration. It still has the same sleek modern design. What changed is the addition of new features. It now has a built-in GPS. This means you will be able to leave your phone at home during workouts. It has been requested for many years, and finally, Fitbit has decided to add it to the device.

What’s more appealing is that they made no compromise on the price. In fact, if you go to Amazon, the previous model will cost more than the new one. Plus, now it supports Spotify, and Fitbit Pay is available on all models. Previously, only the more expensive versions would get that feature.

Special Edition

If you can spend an extra $20, then we would recommend getting the special edition of this watch. It doesn’t add any extra functionality but looks really cool. The special edition comes with a reflective black band and has a classic look to it. It should be suitable for sweaty workouts. If you want to change the bands later, then just press the small buttons on the back of the tracker and it will come off. Then just snap a new one to it.

Display

Similar to its previous iteration, the Charge 4 offers a grayscale OLED touchscreen. Although a grayscale display is good for battery life, having a color display is much appreciated. Some alternative models are offering color displays at a much lower cost. Regarding the visibility, it’s not bad. In bright sunlight, you will be able to read what’s on the screen.

The screen will shut off to save battery life. You can adjust the screen off time from the settings. To wake up the screen, you can just press the button on the left side, shake your wrist, or just tap on the screen. It’s not very polished. You may need to tap a few times to get it working properly. Hopefully, this will be addressed in the later version.

How does the GPS work?

Previously, you would have to keep the phone always with you to map the route. The Fitbit would be connected via Bluetooth to your device to make that work. But now, as the GPS is built-in, you can leave the phone back home. Once you are done with the workout, the progress will be automatically sent to your phone. Plus, the new heat map will show how your heart rate and pace varied throughout the workout. It will give you a better understanding of when you’ve worked the hardest.

The GPS works just as same as in their smartwatches. So that’s nice to see. We also appreciate that you can start the workout before the GPS pinpointing the location. It will work in the background.

Features worth talking about

The Active Zone Minutes is another really welcoming feature to the Fitbit tracker. It keeps track of how much time you have spent, and an elevated heart rate zone. There are three levels of alerts for the heart rate. The wrist band will physically buzz to alert you of the level you are at. A single buzz for fat burn, two for cardio, and three for the peak. The alert can actually get annoying if your heart rate fluctuates too much. But this feature should help you keep a better track of your heart rate.

The Fitbit Pay is now a standard feature for their latest wrist bands. You no longer need to pay for NFCs anymore. The addition of Spotify means you can listen to your favorite music while exercising. Now you can change the music from the band’s display, without taking out your smartphone. Please note, the controls only work for Spotify. Other music apps won’t work at this point.

Then, there are the sleep modes. The basic one will turn off the notification and disable the screen. It allows you to schedule the time, so you can use it in your daily routine. The estimated oxygen variation chart will show how much your blood and oxygen levels varied during the night. This means you do need to keep it worn during your sleep. It can be annoying for some, but these wristbands are quite comfortable to wear. You will get used to wearing it anyways.

If you are new to Fitbit fitness trackers, then here’s what you need to know. The Fitbit Charge 4 will keep track of your daily activities and sleep, as well as indoor and outdoor workouts. These trackers can monitor your heart rate 24/7 and also gives you a better measure of calories burned. The data is synced to your smartphone or PC so that you can measure your fitness changes over time. If you are cautious about your fitness then having these trackers would really be helpful. In fact, these are used and recommended by many fitness professionals.

Battery Life

The battery life of the Fitbit Charge 4 is similar to the previous one. You will get up to 7 days of battery in regular use. If you are using the GPS then the battery life will get down to 5 hours.

Final Thoughts

The Fitbit Charge 4 is definitely a welcoming update from the previous iteration. However, it’s not perfect. It lacks a color display that other models offer. And the battery life drastically drops if you use the GPS. Still, comparing the price, it is one of the best fitness trackers you can find in the market. Anyone looking for these devices should definitely consider the Charge 4.
