Customers say
Customers find the smartwatch to be a good purchase with a timeless design and vibrant AMOLED display, working seamlessly with Samsung phones and being intuitive to use. The sleep tracking features are very accurate, and customers are satisfied with its value. The battery life receives mixed feedback – while some say it lasts about 36 hours, others report it only lasts several days. The charging speed and sturdiness also get mixed reviews, with some reporting quick charging while others experience problems, and some units arriving in good condition while others show noticeable scratches.

Very much enjoying my new watch!
I’m very much enjoying this watch. I refuse to spend much money on a watch, so when this went on sale at a bargain price, I went for it. I came from an Amazfit that was starting to annoy my by refusing to do alerts. This Samsung watch is a couple of generations old and is refurbished. I cannot tell that is isn’t brand new, and everything works well. I have a Samsung phone, so using the Samsung Wear app and syncing to the watch was super easy. Battery life is great – I’m at 75% after using it all day (no way am I going to be wanting to sleep with a watch on!). The step count is accurate. Setting what apps to alert was easy. The display is nice and bright. I haven’t bothered with EKG or other body measurements – I care about step counts. Along with that it purports to measure activity and calories expended – I have no way to know if they’re accurate… Anyway, bottom line – I’m very happy with this watch!

Not much to love
Yesterday I received the Samsung Watch 4 -10/2024. I bought it used and it came as expected a few micro scratches nothing important. I paid about $90 dollars for it. The watch came with 66% of the battery and after setting it up (which was easy) I can say I was impressed by the amount of things the watch can do. However, that’s as far as it goes right to this point. I charged the watch, after setting it up, to 99% battery. I went to bed wearing it to check the sleep monitor at work. It did work as expected. I slept for about 5-6 hours and watch was at about 40% battery. I did not like that at all. It let me know that in full use I probably will not make it through the entire day. I will update on that today because I got full day of work plus gym workout. A serious, and why the 3 stars, is because Samsung failed to alert people (its watch customers at least) that without a Samsung phone you can not use about 40% of the advertised features in this watch, which as I said before there are lots of them. I have a Motorola Razr 2023 and I can not install the Samsung Health Monitoring app on my phone because it is not a Samsung phone (something that it would have giving me paused to buy it). The Samsung Health Monitoring is preinstalled in the watch but it will not work if not installed on your phone. There are some features that still can be used through the SAMSUNG HEALTH app (not to be confused with the monitoring app which measures blood pressure, glucose and the works). You can install Google Fit which is nice for me since I use it for workouts. I have a Samsung tablet which I use for work, but there you can not install the SHM app either, it is only allowed to be installed in phones. I will give an update in couple of weeks. Update 4 days after purchase. After wearing the watch for couple of days I increased my rating to 4 stars. The amount of customization in this watch is impressive. Connectivity is strong it won’t disconnect from my phone easily (one of the problems I have with the Tic Watch that kept disconnecting from my phone and it was a pain in the back while running because I couldn’t manage the music) in the Samsung watch it’s not happening. Battery life is not the best but with some tweaking at night it can be manageable. Eating only 15 to 20% through the night. Changing take 2 hours from single digit to above 90%. So far I’m happy with the purchase. About the health monitor which is one of my major gripes with Samsung, I spoke to few people that have the entire Samsung platform and the average answer was that health monitor didn’t work as good or as expected. Wearing the watch at full power at work and gym, usually 10 to 12 hrs, the watch consumes about 50 to 70% of the battery. So charging it every day is a must. Keep this in mind when buying it. It works for me because I can manage to charge twice a day for about 1 hr. I will update again in a month or so.

Feature packed and comfortable, iffy battery life
Ive had this watch for about 4-6 weeks now. I’ll address the main issue with this watch first, which is the battery life. The battery only lasts about 36 hours, with wifi and Bluetooth turned on along with Samsung Health (without continuous tracking). That’s not much compared to some other watches out there. The US model doesn’t have blood pressure monitoring capability, either. That being said, it does have blood oxygen, pulse and step monitoring sensors. It is comfortable considering the size.As for apps, the Google play store has a lot of apps that can be installed directly onto the watch and when I paired it with my samsung phone, I can transfer pictures and all sorts of things directly to the watch. WhatsApp works on the watch (but doesn’t support videos). Same with Facebook Messenger. Snapchat will notify you on the watch but refers you to the phone to actually see the message.The speaker on the watch has good sound quality for its size and Spotify can be installed on it. Call sound quality is mixed.Calls and texts can be made directly from the watch using its mic and speaker if it is connected to your phone via bluetooth.The band is silicone and is comfortable to wear and easy to clean. The display has decent scratch resistance. I haven’t managed to scratch it at all yet. The bezel still turns and clicks flawlessly.Connectivity is good. I can leave my phone in the house and go outside and still be able to answer calls and messages on the watch.In summary, it’s a great watch, but you need to stay on top of keeping it charged.
