Samsung Galaxy Watch 4 40mm Bluetooth Smartwatch with ECG Heart Monitor, Tracker for Health, Fitness, Running, Sleep Tracking, GPS Fall Detection, US Version, SM-R860NZKAXAA, Black

I decided to upgrade from a fitness band/watch garmin device to this smart watch. I know there are about 3 subsequent versions of this, but mine still works very well after over 2 years. Positives: - I like being able to see at least part of incoming text messages so I can decide if I need to pull out my phone to read them on a larger screen. - The do-not-disturb feature is very helpful in muting text messages when I can't afford interruptions - I do like the variety of fitness tracking options, as well as health and sleep - The battery life is still pretty good even after several years Negatives/downsides: - I still find it hard to cancel notifications rather than just snooze them (the swipe to clear feature doesn't always work--could be the screen protector I use) - It took me a while to realize that having the watch on DND means that calls won't go through on my phone even if the volume is on for that device - Battery does have to be charged each night, which limits the usability for sleep tracking (unless I charge it earlier and then can't track activity/steps) Overall still a quality device and I haven't been compelled to upgrade yet.

I love this watch, as I still continue to use it 6 months later at the time of this review. If your looking at something to help you keep track of the time, exercising, sleep and more, than this is for you. It has a very easy to use app, and very easy to set up, takes no more than 5 minutes to set up, not including the time it takes for the watch itself update. It looks great and functions great. You can add nice wallpapers to the background and change how the watch face looks, with different colors and styles. It does a great job at counting steps and keeping track of exercises. Even if you don't tell the watch your about to exercise it will automatically detect that you are doing one and start tracking calories burned, steps taken, and more! Even if you don't have a Samsung phone it still will work with any android phone for the most part. I no longer have a Samsung phone from when I bought this watch, but I still continue to the watch with my Google Pixel 7a. The only thing about the watch that isn't the greatest is the battery life. This watch will last one day, that's all. Luckily it is easy to charge as it just uses a included wireless charger, so you won't have to plug the watch in. Overall an amazing watch packed with great features for a great price. If your looking for a watch that isn't going to break the bank but also isn't complete garbage than this is what your looking for!

This is my 3rd "Smart Watch". My 1st was a Garmin which was very basic and bought by my wife. I was an avid runner and that was the Garmin's main intended purpose. However, shortly after receiving it, I had to give up running due to prolonged issues with my hip. So, it became a very expensive heart rate monitor - a function at which it excelled. My 2nd watch was a Fossil watch which was an impulse buy. It was visually attractive but excelled at nothing else. It sits on my bedside table and is rarely worn - poor integration with my phone and poor battery life make it slightly better than useless. [A cautionary tale against impulse buying.] I have been hesitant to pull the trigger on a more expensive smart watch but I lost the Garmin watch and really missed having a continuous HR monitor when I exercised. I am an old dude but my fitness is very important and HR zone targets have a proven benefit. It also keeps me on track in the gym. Well, I saw the "renewed" version of this watch, and the price point made it an almost painless proposition to give it a try. So far I love it. I have a collection of watches and usually rotate them for work but since buying this watch all of my other watches are collecting dust. The setup was painless. I have begun using an exercise app that has a continuous HR monitor and workout timer. This is the feature that is most important to me but I love playing with the other features. I emphasize "playing" because none of the other features are terribly important to me - they are merely novelties. But over time I feel some of the features will become second nature. I love being able to see my messages on the watch while at work but with Android I can just as easily see my messages on my laptop while at work [can't do that with Apple!]. Overall, a solid watch. MAJOR CON: battery life. Given the small footprint of this watch, and all that it is doing in the background, I feel a bit like an entitled brat complaining about the battery life but, if I could change one thing, that would definitely be it.

I am a fan of smart watches, over the years I have had a Pebble, then a progression of Samsungs-- Gear Fit, Gear Fit Pro, Gear Sport, and Active2. Before smart watches I was a collector of mid-tier mechanical watches, attracted to watch faces that I liked. (Looking at you Lum-Tec!). Smart watches did not attract me for fitness tracking, but rather for the multitude of available watch faces. Truth be told, I do like the form factor of apple watches, but the 24-hour battery life and needing an iphone are reasons I originally decided to steer towards Samsung. My primary uses are for call / text notifications, Ring door alarms, exercise and sleep monitors, and timers/alarms. Much has been written about Samsung watches, and based on Amazon comments there seems to be a love-hate relationship with the Watch 4, so I am just going to limit my comments to a couple of points. First, battery life. I was happy with the Active2. Battery life with both the prior Active2 and this new Galaxy Watch 4 is OK, not great, for me, usually 2-3 days...The initial setup scheme, unlike the Active2, showed less than 24 hours use from 100 to 12%--so I understand where "poor battery" comments come from. Over time and charging cycles, dependent on the selected watch face, along with power saving tips, I can get a solid 3 days. Power saving tips. AOD “Always on” needs to be OFF, display set to 10 seconds, wrist flick screen OFF, HR measurements set to every 10 minutes except during daily exercise sessions, snore detection and blood oxygen at night need to be OFF, Wireless OFF, NFT toggled OFF. I also found that some settings were set to off, but actually on (blood O2 at night, set to off, but running at night. I had to reset the watch?). Battery life could be much better, Samsung really needs to look at how they implement defaults that consume power considering the vast number of comments that complain about short battery life. Second, initial setup. With the Samsung Gear app already installed on my pixel 4a 5G phone, set-up was easy with a switchover from my Active2. Most of my prior Active2 settings were carried over with the exception of NFT toggled back on, and a required update of the Samsung Health app to show my default exercises. Third, a new marketplace. My most frustrating moment was the fact that previously purchased watch faces are not carried over due to the switch to Wear OS, and away from Tizen. Samsung Marketplace is no longer used for Watch 4. Oh well. There are plenty of options from google play (add watch face to searches) and from Facer. Be aware, increasing the number of complications, animations, and colorful backgrounds seems to noticeably hit battery life. As indicated, I have found a number of preset options that give me a solid 3 days of battery life, with the power saving hints above in play. As for watch operation, it is all very familiar to me. I am learning the new operating system and menu. A positive surprise was a totally flat face allowing the use of glass screen protectors, very easily positioned and attached. The Active2 had a curved edge making the install of screen protectors more challenging and less durable along that same edge. I also like the design of the watch band, which sits mostly flush against the curved case, maybe following a styling cue from apple. If, like me, you had a prior Samsung watch, this is technically an "upgrade"--but lots of adjustments need to be made to obtain good battery life, and some operational issues persist. With the current deal it might be worth a try. IMO, Samsung still has some firmware work to do.

The only smartwatch I've ever had was a fitbit charge 2 so I don't really have anything to compare it to, so keep that in mind. I'm a pretty sedentary and anxious human being so I got this to keep myself accountable for going on walks, meditating, and generally getting my act together. So far it's doing what I want it to. I'm going to say the SpO2 sensor is super janky, and can't decide whether I'm perfectly healthy or on the verge of brain damage from hypoxia half the time. I have no symptoms, and my readings on a regular pulse oximeter and at the doctor are consistently normal so I'm not concerned about this. I love that it auto detects my walks after a while because I always seem to forget to tell it I'm going. It tells me how long it took me to go a mile and how many steps I took and the breakdown after the walk is over is nice. The ECG feature is reassuring as well, as I can share that information with my doctor easily with the interface given. I don't understand the body composition feature so I'll maybe update this review when I talk to my doctor about it in a couple months. I wouldn't use it if you have body dysmorphia though. You can take that tab off both the phone and the watch in the settings so you don't have to think about it if you're concerned. You will need a samsung device to use ECG , SpO2, and a couple other things I can't recall at the moment, so that's a bit frustrating for those who don't have samsung everything. Every feature is very enjoyable, snappy, and pretty much everything I wanted in a smartwatch. I'm pleased with it, am moving more, and when used in conjunction with my other stress control and fitness apps I'm starting to be able to see quantifiable results from all the effort I've been putting in. I can control my music with it, send texts, make calls. My life is easier, my exercise is more fun, and I'm getting to be a lot happier with its help. The battery life sucks, but it's probably good to take it off for an hour or so a day anyway as the band is comfortable but can start to rub wrong. All in all, I'm very satisfied with it. It suits my needs better than I expected. It no longer feels like a frivolous purchase. I didn't absolutely need it, but I'm very glad to have it.

I love this watch! I have the 44mm. I also had the 40mm for awhile until I switched to the bigger model. The battery life is better on the 44mm and the screen is better but only because it's bigger. That's the only two differences between the two. The Watch 4 is fast and good looking. Speaker on it is great for a watch. I mean everything works awesome. There really is nothing I dislike about this watch. Probably the best smart watch I've ever owned. I highly recommend this watch to any Android user. Do note that the ECG and Blood pressure monitor will only work if you have a Samsung phone. The Blood pressure monitor only works in certain countries so depending on where you live if you don't have a Samsung phone the only thing you're really missing out on is the ECG feature. Calls sound great on the watch. Messages on the watch work perfect with Google Messages and GBoard installed. Still no Google Assistant at this time so only the mostly useless Bixby is available. The screen is plenty bright for use in bright sun. I'll say it again; this is THE ANDROID WATCH TO BUY! You won't be disappointed. One more thing, battery life. The battery will last you through the day no problem on both models, smaller and bigger but not much more than a day. Maybe 2 days without AOD on. And the new Wear OS is great. Also, battery life will probably seem bad the first day you use it but give it a few days and somehow some way the battery life improves quite a bit. I give this watch 5 stars and absolutely recommend it!

Ive had many smartwatches. Moto 360, the bulky LG Sport, Fossil Gen 4 and Fossil Gen 5 (that I lost). I loved the Fossil watches because they are high quality watches using WearOS. Never liked Samsung because of Tizen. So when I lost my Fossil Gen 5, I naturally was going to upgrade to the Fossil Gen 6. I did do some other research too and the more I researched, the more I started to like the Samsung Galaxy Watch 4. I don't like bulky watches and the Watch 4 was more slender than the Classic. Reading these Amazon reviews, I was almost scared away. Anything from Google Pay not supported to the touch bezel doesn't work at all. Let me just say, not sure if these reviews were early updates or what but Google Pay works just fine and the touch bezel works just fine (although I scroll with my finger anyways). The touch bezel is good for turning volumes up and down and it works perfectly whenever I use it. Another contributing factor to choosing Galaxy Watch 4 over Fossil Gen 6 is the Fossil wasn't releasing with WearOS 3.0. I believe at the time of me typing this review, the Galaxy Watch 4 is the only released device with WearOS 3.0 and it is a major improvement on previous WearOS versions. I'm not a health nut but the integration with Samsung Health is amazing. I do like to track my steps and sleep and this watch is awesome for that. For sleep, all I do is turn bedtime mode on and go to sleep. The watch does the rest. Monitors blood oxygen and how well you slept. Not sure how accurate it truly is but I do like knowing about how long I've slept. As far as battery life, it lasts at least all day long. Usually longer. I use it moderately at work checking notifications, replying to messages and controlling my music and when I get home from working a 8-10 hour day, my watch is around 40%-30% typically. I put it on the charger before bed, put it on at 100% at bedtime and wake up to about 85% battery for the day. DO NOT LET OTHER REVIEWS DISCOURAGE YOU! I challenge you to do your own research. Watch YouTube videos or even go to a local phone store and look/feel the watch. It's definitely the best watch I've owned to date. If I had to give downsides, it would have to do with Samsungs integration into WearOS 3.0. The Bixby button is NOT reprogrammable to Google Assistant but can be disabled (not remapped). However, from videos I've watched, the Bixby assistant is useful on the watch as it can turn on and off settings by asking it. The other complaint is not being able to reprogram the Samsung Pay button. If you press and hold the bottom button, it opens Samsung Pay by default. Which is annoying if you want to use Google Pay. However, once you properly install and set up Google Pay (and make it default payment method), you don't need to open Google Pay to pay anywhere. Just tap your watch. But if you want to use a different card, you'd have to go into your apps and open Google Pay or assign it to open with a double tap of the top button (that action can be programmed to anything.). With the Galaxy Watch 4 still fairly new, I'm hoping Samsung continues to provide updates from community feedback. And by this time, I've hope you read my entire review and are placing your order now. Stop second guessing yourself, this watch in my opinion is the best out there right now.

Es un smartwach muy completo para quienes tenemos un ecosistema Samsung, el wear OS es lo bueno que tiene, hasta ahora no me parece que me hagan falta las "mejoras" que tienen las versiones 5 y 6, solo el bisel giratorio de los classic es algo que extraño, pero entiendo que no lo tenga justamente por el precio. Es una version internacional, el ajuste regiona es de paises de Africa, pero eso no me ha generado problema alguno, ya sirve la funcion de electrocardiograma y presion arterial. Tiene una bateria pequeña, algo que entiendo han corregido en versiones mas actualizadas, sin embargo por el precio (2800) es una buena adquisicion, siempre que tengas en cuenta que vas a tener que cargarlo casi cada dia; si se te acomoda con la rutina, cargarlo por la mañana cuando te vas a bañar o cuando estas desayunando, o cuando estas en la computadora, puede ser una buena opcion. Si tienes mano y muñeca pequeña la version de 40 mm puede ser buena opcion para que no se vuelva estorboso, aunque tenga menor bateria, aparte de que es mas barato. SI NO TIENES ECOSISTEMA SAMSUNG HAY MEJORES OPCIONES, SOBRETODO CON MEJOR BATERIA.

The Samsung watch is very good. The nee technology has come along way. Very happy with it.

My gf happy

Battery life is hardly a day, if Bluetooth is kept on

for steps tracking also time also others... have time, blood monitor temperature etc...
