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.
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.

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!

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.


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.

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!
