The Charge 4 has worked very well and I have had no complaints following the purchase in August 2021 until today. The device suddenly fell off my wrist because the plastic part of the device which connects to the strap broke off without warning meaning that I can no longer wear the FitBit and it therefore cannot be used and I may as well just throw it away. There is no point buying a replacement strap because there is nothing for the strap to attach to. There was no reason for the attachment to break off as there was no physical or other impact. Whether there is a manufacturing defect or design defect, I don’t know but a device which sells for as much as a FitBit should last for longer than 2 years.

Bought as a replacement for my old one which suddenly stopped working. Disappointed this one doesn’t have the sleep feature on it unless you pay for Premium.

Replaced a Fitbit charge3 which stopped working after 2 years

I’ve now had 2 of the Fitbit watches. My first, a Charge 3, only last just over 12mths when the screen went complete white, which also happened with my daughters after only 10mths so Fitbit replaced it. The second, a charge 4, has only lasted 15mths. The pixels on the top of the watch started to break up and now the plastic clip on the watch that attaches to the strap has snapped off. So, over all not very durable quality at all. I will not be buying another as it’s turning into an expensive busy buying one every year.
I have been in touch with Fitbit, and they are sending me a replacement even though the watch is over year old.

12 months old and the fitbit strap connector has snapped off! Luckily my sleeve was over it otherwise I would have lost the entire thing.
There is nothing wrong with the actual fitbit so I have now had to buy a new strap that houses the entire fitbit.
Seems like this is a common issue and honestly I would expect better from such a big company

I had problems with this disconnecting from the app a few times and it-was a major faff and very frustrating to re-connect. When its working properly i am quite happy with it as it can be customised to my height and step length etc. Makes me aware of how lazy I can be sometimes which is no bad thing.

I have previously had a Fitbit Blaze, but I was disappointed with its battery life and eventually the battery stopped holding charge, so I was interested to see how the new Fitbit Charge 4 compared. Overall, I would say it is an improvement in most areas (although some are not as good as the Blaze)! It keeps its charge much better (although it is new) and is good for day to day wear but the battery life with GPS is disappointing. It is supposed to be up to 7 days normal wear and 5 hours GPS. It all depends on how active you are. I probably get 4 days normal (but I work outdoors and rack up 10,000 steps by 10am!) for GPS I would say make sure its fully charged first and you might make 5 hours.
To begin with it was not straight forward to set up and like all fitbits it is not good if your internet bandwidth is low especially as all support is online! There is no way to manually set the time (which I have found an issue when travelling through different time zones in the past)
It took a while to get the charger working (no smiley face) initially but I think it is just because the battery was so low to start with.
The charging cable is uselessly short especially as a lot of the set up needs to be done whilst plugged in which resulted in my crouched on the floor under the side table! The charger is a much better design than previous models as you do not have to remove the strap and it has a clip to lock the watch into place, which is great once you get it working!
Over the course of the first week there were daily firmware updates which were a bit annoying but I do now have the advertised functions ( I didn’t use Spotify, payment or any of the premium features and I did miss being able to control the music stored on my phone ( I am old fashioned that way)).
The itself strap comes with 2 alternative sizes which is useful but only one has the band to keep the free end in which is a bit of an oversight. the strap itself is very plastic-y and not very comfortable. A softer silicone material would be nicer, but I suspect this will be more hardwearing. The strap attachment mechanism is much stronger than previous models.
The display is black and white and it is very difficult to read in direct sunlight especially as the default display time is so low (the auto hibernate kicks in after about 5 secs which isn’t enough time for my eyes to adjust to the display) and there is no always on option or ability to delay the auto hibernate. The wake action of raising your wrist needs to be done quite firmly and often fails. (It was a pain when trying to take the photo!
The screen itself is an ok size and the swipe/ button functionality take a bit to get used to. I found all the buzzing a little annoying and difficult to stop an activity once it was in progress as it would keep going through a loop of pausing then telling me to press to finish but when I did I got the DND/sleep mode options. I think it just takes a bit of getting used to.
So on to some of the functionality…
Workouts
The fitbit has inbuilt GPS so there is no need to take your phone and do not get the same connectivity loss. It auto detects workouts and you can track six activities on the device, but you can edit in the app/dashboard for example I can change the outdoor activity to horseback riding but it didn’t do anything to modify the stats which would have been nice. If you do autodetect though GPS is not turned on, so you won’t get a map. Various activities log different data but I was quite happy with the heartrate zones, energy burned distance & elevation. GPS does drain the battery
As well as counting steps you record Active Zone Minutes which basically ranks your activity so that a higher intensity workout in the cardio heart rate zone is worth double a lower intensity work out with heart rate in the fat burning zone. It has a daily target of 22 an average of 7 days divided by 150 minutes of weekly exercise. You can customize all your targets in the app.
Sleep & O2- Fitbit gives you an overall score for your sleep, showing awake, light REM and deep sleep periods. I tend to find the less deep sleep I get the more tired I am, and it all seems to be at the start of the night! It estimated my O2 fluctuations, but I am not sure for me this is especially useful, I think the just like to play with the sensor!
Female tracking and food and water intake I just can’t be bothered with as its too much data input for me and my fluid comes not just from water! I did try to use it to log alcohol consumption though as it made me think about how much and when!
Notifications can be enabled for calls and text messages, calendar updates but not WhatsApp messages ????
Overall it does what it says on the tin and has a reasonably easy interface. Battery life and screen needs improvement but am I happy? YES!
