1 review for Fitbit Charge 4

  1. Lucy

    I recently purchased the Fitbit Charge 4 and I have to say, I am not impressed. While the 12.5 mm height is sleek and appealing, the overall performance of the device leaves much to be desired. I was hoping for more from a well-known brand like Fitbit, but unfortunately, it just doesn’t live up to my expectations.

    One of the biggest issues for me is the battery life. At 168.0 hours, it just doesn’t seem to last as long as other smartwatches and activity trackers on the market. This is frustrating, as I feel like I’m constantly having to charge the darn thing.

    In terms of features, the Fitbit Charge 4 does offer some helpful options, including heart rate monitoring, GPS tracking, and workout tracking. However, I found the design to be clunky and not very user-friendly. It also seemed to lag quite a bit when trying to access different menus and options.

    Overall, I would say that there are better options out there when it comes to smartwatches and activity trackers. While the 12.5 mm height may be appealing, it just isn’t enough to make up for the subpar performance and battery life of the Fitbit Charge 4. I would recommend looking into other options before making a purchase.
