   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.

   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?

   The watch itself, is stunning! It’s by far the best looking in all of it’s features i.e., color of watch band, texture of the band and over all style of the round clock face and accents. LOVE the cost! I paid $149.99. LOVE that I can answer incoming calls and the reception is clear as a bell! Texting on it as well, is phenomenal. So many watch face choices and customizing features, I can’t keep count. The colors on the screen and all it offers are more than I will ever use. I have only one HUGE complaint! After everything I was shocked to love and discover, the BATTERY LIFE IS TERRIBLE! I was so shocked. One charge lasts 24 hours. Even when I follow all of the suggestions about how to conserve the battery life. Of all the watches I’ve had over the years, the is by far the worst for battery life. My last 2 watches were Garmin Fitbit Versa 2, and the battery life for that watch would last 3 days at a minimum! I am honestly perplexed that Samsung could figure out to match the battery life as in a Fitbit.

   because it is kinda like an iphone on your wrist, it takes up a lot of batteries. If I turn on power-saving mode and pick the most simple watch-face, then from 6am-8pm I will have 64% left when I don’t receive text message or text back.Images are good, almost like looking at my phone, contrast, colors, and accuracy of pixel is good.Texting- I like how I can text talk and it’ll respond in what I say. This usually drops my battery life most. Btw, the texting language has to be the language of the programmed language of the watch, so don’t try to respond using voice-texting in a diff language than the one programmed on the watch. Like if I programmed it as “English”, I can voice-text only in english and not Vietnamese or Spanish.Sleep-monitoring- in the morning it’ll tell me how many hours of sleep, light-sleep, REM, and more. It’s good, through the pulse-oximeter reading of my sleep patterns, I learned I had sleep apnea. It gives a range of your Pulse-Ox when you sleep at night like 85-95% detailing perhaps that night I was more stressed and didn’t work out, so lung capacity decreased. It’s a good monitoring tool.Water-resistant- I’m a nurse at a hospital, I wash my hands all the time, so far no water issues. I never had to turn on the water resistant option, and use it all the time. Though, after 12 hours, the heaviness of the watch drains me, so I like to give my wrist a break and take it off to charge.Battery life- I have to charge daily with this, can’t go a day without it. But the upsize is that it charges QUICKLY. Within 15 minutes of charging, it can go from 15% to 50%, and from 85% to 100%. It charges quickly, but drains quickly too.Phone reception- I used it once or twice bc I don’t use my phones for calls much but more for instant messaging. Clear reception, my mom heard me well, and we were able to carry a convo while I shopped at Walmart. Wouldn’t recommend using this option in confined space though.Steps- it over calculates my steps, giving me the impression that I’ve walked longer, but no.EKG- It’s good, idk how accurate it is, but so far it’s good.Benefits- when you are on GPS mode, it’ll have it on your watch, and beeps or vibrates when a turn or stop is needed. Really cool, in case you lose your phone while driving, or don’t have a phone holder in your car, this function is cool.

   I was a little scared with the reviews stating battery life is bad but I have had no issue. I charge it to full in the morning when I get ready and that single charge is enough to last all day, through the night and to morning when I charge again. Watch is quick and notifications are convenient. The ECG measuring is kind of finicky and that is my only complaint. Once you figure it out it becomes a bit easier but it is kind of hard to get it to work right sometimes. Overall I love the watch.

   It’s made my life so much easier. I had tried a knock off watch and it was very limited on what it could do, so that was a no go for me. I returned it and bought this Samsung watch and I am absolutely in love with it. I could reply to texts, which was my issue, by mic or typing it out and has all the emojis. It does so many cool things. So many different watch faces, you could change the color on the numbers as well. I was scared about the battery life reading other’s reviews but I have my watch on all day, about 7 am til 9-10 pm and it’s usually between 50-60%. I do charge it every night just like I do my phone, and it charges so fast. I am extremely happy with my Samsung watch 4. I bought different bands because my wrist was getting sweaty and I didn’t like the feeling. I know it’s a couple of years old, now I believe the watch 7 is out but it works perfectly for what i need it for. The range is also pretty great!

   Some people said they didn’t get an oem charger or the battery life sucked or it took forever to charge. This has not been my experience with this watch. I received it with a samsung charger and it charges in less than an hour. The battery lasts all day and I only charge it once a day. I haven’t worn in a the shower or actually used any apps so I can’t speak to that. I use it for Samsung health and it’s motivated me to be more active and eat healthier. For me it looks better than the square watch and fits better bc it doesn’t dig into my wrist.

    Was honestly very nervous about buying this watch due to the constant reviews on the battery life being so bad. And let’s be honest no it is not the best. However the charging speed makes up for that instantly! I charge it when I wake up in the morning before bed and charge it and before I got to bed I charge it. Honestly when I go to bed it’s at 98% and when I wake up i am normally ariund 80% or higher and I am getting ready for bed I get to 20%. Now to give you a time frame to how long it last all day I leave my house at 6:30 am and don’t charge it until 8pm. So not horrible! And a full charge is within 30 minutes. So honestly the battery is not an issue at all! I love everything about this watch!
