  • Very nice watch!
Color: Black Size: 40mm Style: Bluetooth
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! ... show more

  • Very Nice product
Color: Silver Size: 40mm Style: Bluetooth
05/13/2023: A really, really nice smartwatch. My wife has an Apple watch and it is nice, but I have to say that this Samsung 4 is a notch better. Her watch cost $280 after a deal with her phone service. My Samsung 4 was just under $90 from Amazon, and it is a real beauty. I am still learning some things about it, but love it, love it. Quality plus. But, another BUT -- like the Apple Watch, the battery life is terrible. You have to charge it every day -- that is, unless you shut everything off, or down. There is a feature on the watch, where you can select Battery Saver features. Still, so disappointed in battery life. I have a cheap smartwatch that gets me 5 plus days, and it does nearly all of the things needed to keep track of sleep and Heart rate. The cheap watch also has a Blood Pressure reading -- yep, BP. On the other hand, the Samsung 4 has ECG, which is pretty cool, and it keeps a running record that you record for your doctor. I will be trying the different settings on the Samsung, after all, I do not need all of the features that come with the Samsung 4. But, like many others, I do wonder why the cheap smartwatches are able to get so much use out of their batteries, as opposed to these HIGH priced, name-brand watches. As it is, if you plan on using the sleep feature, then you will need to charge every day, or night before going to bed. Getting 2 days of use is a pipe dream if you use the watch to track your movements and monitor your cell phone and massaging, which I do not really need, but it is pretty handy. Maybe you could get 2-3 days, if you shut everything but the TIME off. I will find out. Remember, by shutting all of the AUTO features off, you still have access to manually use, or turn on a feature you want to use for the moment. What a nicely built watch -- more later -- 05/15/2023 Update: Battery life is terrible. You can extend the battery life by shutting everything off, but that defeats the purpose of having one of these Smartwatches, right? Last night, as I went to bed, shut everything down, leaving only the sleep mode on, with a full charge. Got up this morning and it had 86% left. I turned everything back on, played with the settings, on, off, and other features, etc. Also, had to reconnect to my phone to record my sleep activity. I have been up for 2 hours now and the battery reads, 45%. I got up, just under 2.5 hours ago, activated the watch, turned wifi back on to communicate with my Samsung Galaxy 22 phone, and have already used up half the battery capacity. My wife says it is not big deal, after all, she has to recharge her Apple watch every day. Great, so that makes me NOT feel better, not after owning some cheapy watches that never needed charging for 5-7 days, and they tracked my sleep, my BP, my steps, and, really, the cheapy apps were easier to navigate. Seriously, the Samsung is a beauty, but am I really buying jewlery? ... show more

  • Very nice product

This smartwatch is really nice. The 40 mm model looks good and is comfortable. Battery life is less than 2 days with all the functions activated, but it's what is promised, so no surprise here.

  • First Smart Watch, Lots of Power, Short Battery Life
I purchased the Samsung Watch 4 because we had so many sunny days this Spring and I could not read my old Fitbit Charge 4 in the sunlight, even in the shade on such days. I tried the Charge 5, which was readable, but lacked features that I liked on the Charge 4. I purchased the Samsung because it seemed to do everything that I wanted. This turned out to be only partly true. First the good: the screen is very readable even in bright sunlight. It was very easy to get up and running, bonding to my Android phone quickly and easily. Its capabilities go well beyond those of the charge varieties of Fitbits, as with answering one's phone, conducting phone calls, showing map directions from google or other map programs when walking about a new city, serving as a flashlight, and many other features that I've not tried. Its like a smart phone on your wrist, except with a much smaller screen. Second, the bads: the battery lasts 30-40 hours in my experience, with GPS turned off and Wifi on automatic. This is far less than the Charge 4 will run almost a week on one charge, and is a bit of a nuisance, but not a deal breaker since one can charge it in the evening in about an hour. It turns out that one of the features I was looking for, stair counting or elevation measuring (which is lacking in the charge 5), is a feature of the watch 4, but it doesn't work very well or consistently. It under counts them by quite a bit. (Yesterday, it counted 4 flights on a day when I walked about 20.) The other disappointment is with the software for tracking exercise. You can only use it on a phone (or perhaps an Android tablet), rather than on any device you might want to (as with a Fitbit). And the data display is inferior to that of all the various Fitbit apps (android, windows, apple). I had naively expected it to be better than Fitbit's, rather than more basic and more difficult to read and make sense of, and limited to just the phone. For example, there is no Samsung health app for a PC--at least that I could find. Overall a very good product, with a bright clear and responsive screen, lots of apps for the watch, and the convenience of taking care of many phone chores without taking the phone out of one's pocket or pack. ... show more
