A great upgrade from a charge 2 but some things to note...

Reviewed in the United States on April 21, 2020

Color: Black/BlackEdition: RegularVerified Purchase

Got this after my charge 2 died and wow is it and upgrade I really love it so far! Fair warning though on some things I didn’t realize: you need Spotify premium to use any of the Spotify features at all which was kind of a bummer. And according to their website if you use the GPS feature the Fitbit battery only lasts 5 hours. So you have to be careful to turn GPS only on and off when you need it when you’re exercising and not just leave it on to auto recognize which is a little annoying but not a huge deal. Also a few features require that you allow them to run in the background for them to “work properly” I don’t like to have things do that to try and preserve my phone battery so I turned off those permissions but left the others on and so far I haven’t had any other problems because my Fitbit still syncs throughout the day and I think can still get data that way. My boyfriend loves the sleep mode feature that turns off notifications and screen wake so when I toss and turn at night I don’t accidentally blind him with my watch screen if it goes off.

Pretty good, with some gripes. Buy it on sale.

Reviewed in the United States on April 23, 2020

Color: Black/BlackEdition: RegularVerified Purchase

I won't be like everyone who gives a bad review because they clearly got a dud (or user-error as it often is). I'll give it an honest assessment.

The app is amazing, that goes without saying. The quality of the band is nice, but it's a bit hefty, made bulkier by the textured diamond pattern in the band. The clasp is a bit cumbersome as well, and feels a bit like cheap plastic. I'll reserve my judgments on that until it breaks. Doesn't inspire confidence though.

The watch itself seems to be very accurate, it's comfortable, and has some nice options. The pressure button on the side is a little hard to press, I wish you could change the settings for the sensitivity. When pressing, it requires you to stabilize the other side with your thumb or else you'll just push the watch causing it to slide toward your hand. The UI on the app is clean and simple, although I wish it allowed to customization. I don't need all the settings and stats it comes with, and many you cannot remove from the UI. This makes you scroll more than you'll probably want to to get to the features you like. If we could at least re-order them, that'd allow for quicker navigation.

My final note is battery life. FitBit claims 7 days of battery life. Today is Thursday at 8:41pm. I'm at 70%. I gave it a full charge all night Tuesday into Wednesday morning. Within an hour of pulling it off the charger it was down by 5%. At the current rate, it'll likely be dead by Sunday which is closer to 4 days. Keep in mind, since I charged it fully, I have NOT exercised. It's quarantine and I'm lazy. I can imagine the battery would only last 2-3 days with moderate to heavy frequent exercise.

That's my review. Don't got much else to say. It's a decent watch, but I'd wait for it to go on sale.

Wont turn on during set up.

Reviewed in the United States on April 18, 2020

Color: Black/BlackEdition: RegularVerified Purchase

I finally received my Fitbit and unfortunately it just has a black screen. I followed all directions, which is charging it and pairing it up to my phone. But as it was paring, the screen just turned black and when my phone tries to finish the set up and asks me for a 4 number pin, I can't type them in because I can't see them. I tried a reset by placing the fitbit on a charger, and nothing happened. There is a vibration when I press the button, but nothing more. I really needed this to work by tomorrow and now this happens. It's a great disappointment.

GPS is good, special edition band is not...

Reviewed in the United States on May 6, 2020

Color: Black/Granite ReflectiveEdition: Special EditionVerified Purchase

Fitbit's App:
Let me start by saying, the Fitbit app is unparalleled for sleep, diet and water tracking. I have tried to move away from Fitbit due to my propensity for longer runs, but the features covered in their one app bring me back every time. Simply stated, it presents the most holistic picture you're going to get of your health inside ONE app as a result of wearing ONE fitness tracker.

Charge 4 as an Upgrade (i.e. GPS):
Specific to the Charge 4, with a note that *ALL OTHER THINGS ARE EQUAL CALIBER TO THE CHARGE 3*, the GPS (which is really the only major new feature of the Charge 4) is good. The GPS takes seconds (maybe 10 to 20) to connect and then you touch the screen and off you go. I wore the Charge 4 and my Garmin for the first few runs to compare tracking (my garmin is a triathlon model, not a fitness tracker model, & used more for races and longer distance running due to battery life) and the GPS paired fairly well across both units. The Fitbit found its satellites far quicker than Garmin, but seemingly gives extra distance when going around corners. I have one corner I hit on my out and back 3 miles runs and the GPS maps indicate this is where the magic happened, but that being said I would usually hit the 3 mile mark on the Charge 4 around two or three strides ahead of my Garmin. No biggie for the shorter/daily training runs. I would say the Fitbit Charge 4 stops being your optimal choice if 1. You are fine with carrying your phone constantly and therefore do not need GPS or 2. you are going to be out doing your activity for 2.5-3+ hours. That's where the battery use for GPS expenditure becomes cumbersome. At a moderately paced half marathon, you're into Garmin/Coros/Suunto/etc.

Special Edition or Base:
Specific to the Charge 4, the special edition boils down to a unique band, that happens to be absolute junk (with reflective fabric!). The super special band looks a bit awkward with the unit, won't survive sweat for very long without needing to be washed or soaked, and felt & looked like it didn't fully connect into the unit at the clip ins and might randomly separate it tugged on the wrong way. (Could have been mine was defective, I don't know) my recommendation either way- save the $20 bucks, get the basic Charge 4, and if you're into colored/specialty bands, any band that is marketed for the Charge 3 or 4 will work with the Charge 4. I am currently using the Charge 3 special edition band (white rubber with black clasps) on my charge 4. It works perfectly.

Out Of The Box:
I had no issues with any part of charging it, pairing it, or the firmware updates needed at launch to bring it to current. No black screens of death either.

Battery Life:
And the battery does die faster when using GPS, but that actually happens to all fitness trackers not expressly made for GPS monitoring. You can't have built-in GPS tracking on a unit THIS size, with ALL the fitness tracking features it has, and expect battery to last a full week. With active GPS use for an activity a day plus all day & night wear/fitness tracking, I'd estimate you'll get 3 to 4 days out of each charge.

well this is disappointing

Reviewed in the United States on April 20, 2020

Color: Black/BlackEdition: RegularVerified Purchase

So just like another review on here ... my fitbit will not turn on during the setup ... it will slightly vibrate when I press the side button but the screen will not turn on at all. So disappointed ... will try more but I think I will be returning it tomorrow 😥🥺 Update!!! I got it working and now it seems to be good ... steps are accurate and also the GPS is great. Originally marked it as a 1 star but bumped it up to 3 since it is working well now.

MASSIVELY dissappointed by the battery life.

Reviewed in the United Kingdom on April 19, 2020

Color: Black/BlackEdition: RegularVerified Purchase

A single 10k run (c. 1 hour 20 minutes, incl. warm up and cool down) took the battery from 60% to 9%

Absolutely no chance of using this to track a half marathon, then...

Update:. Battery life seems to have become a bit better after a firmware update. However, it's the distance tracking that's now making it unusable. It's widely optimistic, with every run coming in 15-20% over the actual distance, checked against maps and Strava!

Nice upgrade from Charge 2

Reviewed in the United Kingdom on April 18, 2020

Color: Black/BlackEdition: RegularVerified Purchase

Got this for fact was waterproof and had built in GPS.

Initial set up frustrating appeared to be stuck on set up screen, but what I realised was to return to home screen, (watch face) you need to gently hold either side of the screen – this is also the key for everything else – if you are in one of the menus just hold both sides of the screen and you go back one level in the menu – finally getting back to the main screen

Easy setup, multiple display options, easy to use, GPS appears to be as accurate as apps such as ‘Map My Walk’ using the phones GPS

If using the auto detect activity the GPS does not activate, (so if you want a map, which is why I got it), you do need to manually select the activity you are doing

Display easy to read, depending on watch face and your eyesight, even in sunlight, rapid menus and intuitive once you get over the initial ‘how do I get back to the watch face’ GENTLY HOLD BOTH SIDES OF THE SCREEN.
Battery after two days is down to 56%, but that is probably down to me playing with it constantly finding all the bits and pieces it can do.

Overall delighted with it, (so much so just bought the wife one as well)

Nice neat device, has extra apps, including the contactless payment which was a doddle to set up, that I may or may not use in the future but does everything I hoped and would recommend

Have now had the charge 4 for a few weeks, still delighted with it, but have noticed a couple of things, if using the GPS for long periods (like a 4 hour walk), this does seem to drain the battery quickly and needs charging every couple of days

Also a couple of times after starting the exercise going the tracking has switched off, but I think this was due to me having the strap too tight so when putting my hand into a press up position, I was touching both sides of the screen, and it was going back to main screen.

Android OS 7,0

Reviewed in Germany on April 17, 2020

Color: Black/BlackEdition: RegularVerified Purchase

Voller Begeisterung habe ich (Besitzer der Charge 2 und eigentlich sehr zufrieden) mir die Charge 4 gekauft, denn endlich gabs hier die 2 Dinge, die ich bei meiner Charge 2 bis jetzt vermisst habe: GPS im Tracker und eine gewisse Wasserdichtheit. Als der Tracker ankam, wollte ich sofort loslegen. Bedienungsanleitung war nicht in der Verpackung, aber der Hinweis, dass ich über die App in meinem Smartphone den Tracker hinzufügen soll und dort durch das Menü geführt werde. Also startete ich meine App und - tja, die erkannte, dass ein neuer Tracker in der Nähe ist, aber - mein Handy hat leider nur Android 6.1. Und somit konnte ich den Tracker nicht installieren, nicht ausprobieren, denn der Tracker braucht mindestens Android OS 7,0. Tja, jetzt habe ich die Hardware, aber nicht die Software. Zu blöd, dass man das erst rausfindet, wenn man den Tracker zuhause hat. Also zur Warnung an alle: Erst mal checken, ob das Betriebssystem auf dem Handy passt. Wäre ja zu schön gewesen, wenn das schon vorher in der Werbung für den Charge 4 irgendwo gestanden hätte. Ach ja, und die Armbänder, die ich mir zum wechseln gekauft hatte, können natürlich auch nicht angebracht werden. Vielen Dank auch dafür.

Charge 4 from Charge 3, a good step up

Reviewed in the United Kingdom on May 3, 2020

Color: Black/BlackEdition: RegularVerified Purchase

I've been a Fitbit user for a number of years, originally having the Flex 2 and most recently the Charge 3.

I found, as others had on the internet, that my Charge 3 was becoming increasingly frustrating and pretty useless when calculating my running and cycling distances. Growing ever frustrated, I switched to the Charge 4 on hearing Fitbit had introduced an in-built GPS, in the hope of having relatively accurate data.

On these grounds, I am not disappointed. The GPS is really very good, particularly for what you pay. Having tested in on a number of different runs and cycles, predominately in woodland, I've found that it's very accurate (particularly in comparison to the Charge 3).

I'm not so bothered about the Spotify or pay features (if you're UK-based), which I know others are grumbling about. In my opinion, if you want these sorts of features, you should look for a smartwatch. I find these sorts pretty gimmicky / useless if you're looking for a fitness tracker which isn't designed to be a smartwatch.

I've also not had the technical issues which some seem to have.

The battery is definitely nowhere near as good as the Charge 3. I suspect this is because of the GPS - which they DO advertise. I've noticed I'm having to plug in my Charge 4 twice at least twice as frequently as the Charge 3 (going for at least 3 runs and 2 cycles with GPS per week). This can be a little jarring if you're used to the battery of a Charge 3, but considering the size of the device with GPS running, I think people are being too harsh on the battery life.

All-in-all, I'm pleased with the device. Fundamentally, it's not going to let you run or cycle for 4+ hours using GPS (particularly in GPS challenging scenarios). If this is a problem for you, look elsewhere, but be aware you're not going to find a device which is as slim and powerful. I'd recommend this device if you're looking for a slimline activity tracker which is GPS enabled, it reads your heart-rate, has a sleep-tracker and connects to a clever app. The price and quality seem to be near-unrivalled in the field, so I really do think there have been some overly strong criticisms of this device.

Don't buy these, they haven't been tested and aren't robust...

Reviewed in the United Kingdom on April 29, 2020

Color: Rosewood/RosewoodEdition: RegularVerified Purchase

I bought my first FitBit and at first, the screen wouldn't respond so couldn't be connected. I left it for a day and hey presto, it came to life. However, the strap then broke and it fell off my wrist whilst cycling and was smashed.
So, I order a new one and same again, the screen won't respond so can't be paired. Maybe I'll leave it another day again.
Either way, they just haven't been tested properly and aren't robust if they won't stay on your wrist!
