Samsung Galaxy Watch 4 Classic 42mm Smartwatch with ECG Monitor Tracker for Health Fitness Running Sleep Cycles GPS Fall Detection Bluetooth US Version, Black (Renewed)

Save battery by adjusting settings in watch OS!
Recently made the switch from Apple to Android after 14 years of Apple. This is not a “chose sides” thing, more than curiosity and trying something new.I’ve had the Apple watch since gen 1, and let me tell you, the Apple watch does not offer the flexibility of customization and charging like this watch does. Just like my Apple watch, I had to dig into the settings of this watch to limit unnecessary algorithms from operating in the background thus, draining my battery. The battery life on this watch could be dismal at best if left at default settings.Recommend watching a few YouTube videos to learn about certian features to disable to conserve battery life.I personally don’t want Wi-Fi or raise to wake active. Unlike my Apple watch, this has an “always on” display.On my Apple watch, certain apps kind of work on my watch, “but don’t really work”. This watch, you get all the features and customization that you’d expect. And I also have the ability to choose if my watch and phone make sound when a notification comes in.With my Apple watch, the default setting is, phone is silent, and watch is the notification tool. Couldn’t even adjust sounds for notification. This watch, you get a choice.The one last thing…… With my Samsung phone, I can lay this watch on the back of my phone and charge the watch!!!!!I didn’t even know this until I watched a few videos about the battery life and happenwd to come across it on YouTube.So, being an engineer, when I travel to construction sites for work, I don’t have to carry a separate watch charger whilst lodging.I simply plug in my phone, turn it face down, lay my watch on top of it, and boom! Charging!I’m not going to sit up here and say Android is better than apple,For me, the flexibility of customization is King! And all my apps work with all expected features available to customize!Make sure y’all watch those videos to save battery!

Refurbished watch is fantastic [18 months after purchasing]
This has held up against bumps and scrapes and smashes without looking different the entire time I’ve owned it, battery life is still fantastic, functionality is good, it was helpful for getting around London. Tap to pay works great, the only thing it will not track well is your blood oxygen level. I’m a healthy man in my early 30s and the blood oxygen level is very consistently off. My wife is an accomplished nurse at Mayo Clinic, if my blood oxygen levels were what the watch claims, I’d be blue in the face and she’d be taking me to the emergency department daily and I’d have to be on oxygen tanks all day.All other aspects of the watch have been great. Connection to either wifi or bluetooth is consistent and strong, it reacts quickly, it’s comfortable to wear daily.My only complaint is that it does absolutely have to be charged daily, which I’ll admit doesn’t take long, but it does need to happen if you make full use of the watch. Which is one down-side if you want/need accurate sleep tracking.But that said, the keyboard works great, there are tons of official Samsung watch faces and far more with 3rd party apps that get new faces regularly and look great, all functionality of the watch is very easy to access. You cannot really use this as a mini cellphone if you have literally any expectations of battery life or making long calls, but you can live out your Johnny Quest dreams of having a wrist communicator (so long as your phone is somewhere relatively closeby)

As expected
The watch came exactly as described, condition is practically brand new, with a nice rubber watch band, the Samsung charging cable, and a generic BLU charging brick.After using the watch for two weeks now, my largest concern that people complained about is battery life, but with research and experience the lifespan of this watch battery is at most 2 days even if you had bought it brand new. The charge can last those 2 days if you are a minimalist user, as in no wifi, no Always On Display and only Bluetooth, but with doing exercise tracking it can run the battery down to 1 day of use. This is fine for me as I don’t use it for sleep tracking so I simply place it on charge at bedtime.On comparison, the amazfit watches last way longer in terms of battery life even with workout tracking, they last up to 5 days, and more with basic use, however the Samsung watch does have significantly more features.This buy was worth it and I would recommend if you’re looking for a Samsung brand watch at a reduced price

Al principio pensé que no iba a funcionar del todo bien pero ya llevo una semana usándolo y me ah servido de maravilla, además tiene varias funciones; inclusive eh podido instalar un juego y se pueden ver videos desde el reloj (desde el navegador samsung), se pueden tomar capturas de pantalla presionando los dos botones en caso de ser necesario y de manera automática aparece en la galería del teléfono y en la del reloj. No sé si sea en todos los teléfonos pero como referencia yo tengo un samsung y le va bien.Tal vez un aspecto a considerar sea la duración de la batería pero creo que es dependiendo del uso que le de cada usuario.En cuanto al servicio de envío a sido excelente, el producto venia super bien empaquetado e inclusive llegó antes de la fecha estimada.Personalmente me ha gustado muchísimo y la verdad es un producto que recomiendo, en especial si se quiere iniciar con una integración al ecosistema samsung.

No incluía la caja original, pero fuera de eso es un gran reloj, con grandes capacidades. Lo utilizo para controlar mi hogar con la app de Google Home y no tiene problemas. Son bastantes los softwares que soporta y aún me queda por descubrir sus capacidades.
