Feature-Packed Fitness Tracker – Reliable, Lightweight, and Great Battery Life
The Fitbit Charge 4 is an excellent all-round fitness tracker that balances sleek design with powerful features. It’s lightweight, comfortable to wear all day, and the strap feels durable without being bulky. The built-in GPS is a huge plus, letting you track runs, walks, or bike rides accurately without needing your phone. The tracker covers everything you’d expect—heart rate monitoring, step counting, calorie burn, sleep tracking, and swim tracking (yes, it’s waterproof!). The 7-day battery life easily lives up to expectations, even with regular use, and charging is quick and straightforward. I particularly like the sleep insights and Active Zone Minutes, which help keep workouts more focused. The Fitbit app is easy to use, with clear graphs, daily summaries, and motivation to keep moving. Notifications from your phone (calls, texts, and app alerts) also sync smoothly to your wrist, which is handy without being overwhelming. ✅ What’s in the Box: Fitbit Charge 4 tracker, two strap sizes, and charging cable. 💡 Best For: Anyone who wants a reliable, mid-range fitness tracker with GPS and strong health features without paying smartwatch prices. If you’re looking for something that’s accurate, long-lasting, and packed with useful fitness tools, the Fitbit Charge 4 is a solid choice and excellent value for money.

Nice upgrade from Charge 2
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.

Good, although a few shortcomings to note
I am a first time FitBit user, and have had my Rosewood Charge 4 for about a month now. I am overall very happy with my purchase. First, the positives: - it has made a real difference to my motivation to exercise and meditate more regularly. N.B. I use it for cardio circuits and strength training. I have not yet tested the GPS properly on a run. - heart rate analysis in general is great, especially during exercise. The different heart rate zones (fat burn, cardio, peak) are useful indicators. I cannot however comment on how accurate this is, as I have not used it in conjunction with a heart rate monitor. - sleep analysis is great. The sleep score and bedtime reminders have made me a lot more strict about getting to bed on time. - SmartWake alarm feature has made a real difference to how well rested I feel when I wake up. I no longer rely on my phone alarm, and instead wake up gently at my lightest stage of sleep which is great. - Battery life is amazing. Once charge lasts me at least 5-7 days. - No issues with syncing so far (although a different story when it comes to text/WhatsApp notifications - see below). The negatives: - The screen display sometimes doesn't light up when you tilt the watch towards you. It often takes a more exaggerated gesture / button press to light it up. - Text/WhatsApp notifications are EXTREMELY temperamental. Multiple times a week I find that my FitBit has not synced to display my phone notifications, and find a message on the app stating "Notification service not running. A phone restart is required to re-enable notifications on your tracker". What's even more frustrating is that a restart doesn't resolve this issue. Instead, the only solution appears to be going into my phone settings, clearing data for the FitBit app, and then logging into the app again and enabling notifications. I think this is a wider issue with FitBit compatibility with Android phones, and is not Charge 4-specific. I am currently using a Huawei P20 Pro. - The Spotify feature occasionally disconnects and unlikely to be of much use. It's more like having a remote on your wrist - useful if you're playing Spotify from your phone without your phone nearby and want to pause/skip a track. The only real use I've found for this feature is when I'm listening to music in the shower! - The Charge 4's strap is quite bulky on smaller wrists and the rubber is pretty inflexible (see picture). My wrists are very small - around 5ish inches - and this means there is a lot of space left when I tighten the strap as far as it can go (for me, the third hole from the smallest). I bought a woven strap separately to try and remedy this, and it does look better but hasn't completely resolved the issue due to the width of the device and strap connectors. If this likely to bother you, get a different FitBit watch. - The rubber on the Charge 4 strap does wear slightly with use (giving it a grey-ish tint). None of the above are dealbreakers though. If you're a first time fitness tracker user you are likely to still be very happy with your purchase!

Great Fitness Tracker / Smart Watch
In one phrase: this is a great fitness tracker / smart watch. Battery: I have it for more than 2 weeks now and the battery life is very good. It all depends on the GPS of course, but if you run 30 minutes a day with GPS on you will have it lasting 3 days. It always takes a little less than 2 hours to charge, it doesn't matter if you use a super charger or your computer USB port. UPDATE: Now you can use "Dynamics GPS", meaning it'll use your phone GPS when available, saving battery and increasing precision. GPS: the accuracy is okay, it syncs quite fast, you can stretch while waiting. But I don't think you gain much from it. Apart from a bit more accurate distance measurement and fancy looking maps (route) in the app, there's no gain. I recommend you turn it off and increase your battery life and you still are gonna get all the metrics that really matter. Heart Rate Monitor: my readings are very accurate! Some people have reviewed this Fitbit and warned about its inaccuracy, but I think they are either wrong or have some issue with their "setup". I have thick veins, easy to read, maybe that helps. I don't even wear it tight. Features: I don't use the Spotify app, that gladly can be removed, and I noticed that by enabling the notifications (at least with Android) I get all the smart actions for each notification, that includes media control over YouTube and Google play music that I happen to use. That also means quick replies on WhatsApp and alikes. Fitbit Pay: works nice with AIB in Ireland, no need to have your phone nearby, and the PIN unlocks it for 30 minutes or so, so you don't have to enter it all the time. I'm currently trying to add a second card from TransferWise and having difficulties so I'm in contact with 2nd level support to try and make it work, it looks like it's gonna work eventually. UPDATE: TransferWise card added and working! Waterproof: I wore it all the time, under the rain, washing hands, taking shower, soap everywhere, under hot water in a filled bathtub. So far so good. I'll try it in sea water soon to have a final view on this subject. Finishing: the straps really don't connect that we'll to the body leaving a gap that fills with dust every day. Once a day I take it off and clean it, not a big deal to me, but that's really a downside, even if a small one.

disaappointing battery life but does what it says
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!

An awesome upgrade from the fit bitt alta
I bought this to replace my faithful Fitbit Alta, which didn't have a lot of "bells and whistles". I was at first overwhelmed with all the features of Charge 4, but I quickly began to appreciate the accuracy of the heart monitor, as I am a cardiac patient. Also, the sleep tracker is brilliant, although, it often thinks I am asleep when I've been reading in bed for a while, before I drift off. So, it might be a bit too sensitive. However, after having it for several months, it popped of my wrist one day, and it broke off one of the parts that attaches it to the strap. I was prepared to pay to fix it, it's that good. But as I logged in to see when I purchased it, I found the warranty and began the process to return it, which consisted of a couple of clicks and a bit of typing, packing it up, printing out a lable, and sending it off. A few weeks later, I recieved a brand new Fitbit, as apparently, they were unable to repair mine. (Although, they never said that...they just sent me a new one.) In fairness, I realised, when I read the instructions on the new one, I'd been wearing it too tight...so that may be why it broke. (shhh..lol) Overall, I'm well impressed with the whole purchase and the product. I think I'm a Fitbit lifer now.

Nice watch but let down by the battery.
Bought this as I wanted to keep myself on track with my fitness. I do yoga and walking and thought it would be great to see where I had been with the gps. It’s easy to use and is great if you want to look at the time and use it as a step counter. BUT and it is a big but the battery is rubbish if you have anything else running. I don’t have messages from my phone, I’ve turned off nearly everything that might drain the battery including having the heart rate on even just for exercising and it still only lasts for 2 days if I’m lucky. It’s run out of battery on a couple of my walks which is so frustrating. I didn’t buy a sports watch as I didn’t think I needed it but I wish I had now as this doesn’t seem to do what I want unless you charge it every day. My husband has a sports watch as he does triathlons and his battery lasts for 7 days even with all his training. So before you buy one think about what you want to use it for and how often you want to charge it. I do like the watch as it is smaller than a sports watch but I feel a bit let down as you can’t do much unless you charge it every day. Don’t be fooled by the up to 7 days battery life, I should imagine it only does that if you leave it on the bedside table. Update 24.06.20 I have a real love it hate it relationship with this watch. I went back to work recently and my walks got shorter so I could fit them in my day. I managed to get 3 1/2 days out of 1 charge which I was pleased with. Today is my 3rd day after a charge, I’ve been on one 5 mile walk and was on another with 46% battery life left and it ran out of battery 3 miles in. If the battery was better this could be a lovely watch, I like everything else about it but again I’m left feeling a bit disappointed with it.

Read this before purchasing and stressing out..
I thought I did my research, wow there was one aspect I missed, the setup. After struggling to get the Fitbit to work, I dug deep into the web and found out that when you start to set up your new Charge 4 up you will have to update the firmware. Unlike most new devices though this can take a up to 48 hours to come through 😲. Now that it the Charge 4 is updated it works a treat, the GPS function is brilliant. So don’t get too stressed it is a good fitness tracker.

Caro, ma ottimo
Aggiorno la recensione dopo che Fitbit ha finalmente rilasciato l'aggiornamento con la funzione Smart Wake (sveglia nel momento di sonno leggero), quindi posso dare tranquillamente 5 stelle. Evoluzione della linea Charge che guadagna il GPS e diverse funzionalità software, non starò a fare una recensione delle caratteristiche perché ne trovate a milioni online. Vi dirò quello che va e che non va. E' un Fitbit, quindi è caro, ma il design è molto curato e non sfigura quando dovete uscire la sera. Rispetto a Charge 2 e 3: la cassa è in plastica, probabilmente necessario per la ricezione GPS. Purtroppo questo significa che la sensazione è di prodotto un po' meno premium, dall'altra parte se ne apprezza la maggiore leggerezza, al polso è estremamente comodo. E' in definitiva un prodotto ben fatto e curato sotto tutti gli aspetti. Vari miglioramenti rispetto ai predecessori sia hardware che software. Con il Pixel, nessun problema di accoppiamento o disconnessioni. Funziona perfettamente, le nuove caratteristiche rispetto alle serie precedenti lo portano quasi alla perfezione per quanto riguarda le feature di una smart band "generalista", quindi non dedicata all'allenamento sportivo agonistico, ma a un po' di fitness, ricezione notifiche ecc, per chi non vuole le dimensioni di uno smartwatch. Durata della batteria di qualche giorno, rispetta le aspettative per il tipo di prodotto. Lo consiglio a chi vuole un tracker che funzioni bene e che sia anche un accessorio bello da indossare. Si accoppia bene con un orologio tradizionale (orologio a sinistra e tracker a destra).

Great fitbit
Love the charge 4. Does everything that i need it to do. To date i have had 4 charge 4s so far. I am rough on them ( farm life with horses)and they usually last a couple of years to 3+ years. But the last 2 that i got didn't last cause the connector where the bands attach broke off. I tried to glue them but didn't work. Wish bands were interchangeable with a charge 5 though, so wouldn't have to buy a whole new set of bands if upgrade to a newer model.
