Samsung Galaxy Watch4 Aluminum Smartwatch 40mm LTE - Silver (Renewed)

I chose refurbished condition with a 3 year warranty on this 40mm watch 4 to save some money and get most of the features that are available, and all of them that I need. I chose the 40 mm watch because I have a skinny wrist and wanted something to track my sleep with that I wouldn't notice on my wrist throughout the night. The battery life is as expected for the size. I have to charge it in the morning and at night in order to do health tracking in the day with walks and biking, and sleep tracking each night. Although since it is new, I have been installing a bunch of apps and playing with the watch faces a lot. Maybe once I have gotten used to it after a while, the battery life will improve some. I keep battery saving on, and am playing with macrodroid and tasker to better automate modes and improve battery life with this usage. The blood oxygen reading is possibly not always accurate because it needs your arm in an elevated position to get a good reading, and I use it primarily at night to help detect suspected sleep apnea episodes. There are gaps in the sleep tracking too, and I have the watch tight on my wrist. But overall, it tracks the majority of my sleep, and I am impressed by it. I got the LTE version so I could do numbersync with ATT. Be aware that if you intend to use this feature, currently you have to activate the watch and pay $10/month for its own plan, and I have the unlimited Extra plan. I have not done this yet to provide any feedback on its usability. I am glad I got the wifi version for faster transfer speeds instead of Bluetooth only. The watch packaging is pretty basic. You get the watch and a generic band and generic charger. Both work just fine, just know that it won't be in the original box. I didn't care because I always just throw that stuff away right as soon as I get it. The charging takes 1.5 to 2 hours to full charge. Don't use it a bunch when it charges or you will get an overheating error. When you first get it, you will likely have no battery, and it takes a while to get it up to full operational speed due to numerous updates that will likely download and install. Also the battery life really sucks the first 2 days because of this. Overall though, I recommend this if you have scrawny wrists like me, don't want to spend a fortune, and don't mind the smaller battery. Good watch in great condition. Get the glass screen protector for it. Nice and thin and might save you some hassle if you are rough with things like me. Hope this helps.

First of all, I love using my watch and it is extremely helpful in my everyday life. From checking simple notifications, to keeping track of time, and replying back to text messages while I'm driving, this watch is amazing. I only have one issue with the watch. When i first got it and set the watch up, I noticed that it was using an extensive amount of battery power, when I wasn't physically using the apps on the watch. I did some checking in the settings and watch preferences using the galaxy wearable app on my A42, and I discovered that the watch was automatically creating workout routines, taking my blood and oxygen levels every 5 minutes, and a bunch of extra health and fitness widgets and apps that I didn't need. Once I turned all of the extra monitors off, the battery life increased to 1 day and 23 hours. I've read a lot of the reviews fro the used version of this watch, and reviews from the SAMSUNG website about this watch having poor battery life. I think that people just don't know how to configure their devices properly. I would buy this used/renewed version of this watch again if my watch broke, and I would refer this to anyone looking for a watch that has a SAMSUNG phone.

I love the look and feel of this watch. I had a Fitbit versa 3 before this and loved it, but it died on me and I decided to go for the smartwatch s4. It does everything I want and more. The band is comfortable and this is water resistant. You can go in the water with it and it has an option to block water from the watch. Really, the only think I do not like about this watch is the charger and battery life. I literally just got the watch yesterday and had it charging over night and it only charged half way. I finally got it to 100% and only 5 hours later and barely using the watch, the battery is at 35 %. How am I supposed to get accurate steps, sleep score etc. if I have to continually charge the watch. Update: I ended up going back to the fitbit Versa 3. I just couldn't deal with the low battery life of the Samsung watch. Too bad because I really did like the watch other than that

This is worth the buy if all your looking for is to be able to track your health and call/text from your watch. The main issue I have is battery life, it barely gets through 8 hours of light use. Have to charge every night. The apps for the watch a great and the customization the wall paper and overall theme is great. Couldn't really ask for more from this watch

Very sturdy and informative. No problems with this watch work as intended.

I was thrilled to receive my new S4 int he mail. Love the features. However, the charging cable did not work at all. No response. I have an old docking station charger for an S2, and used it successfully one night but only to 78%. Last night it charged to 22 %.It shuts down and gives e an error triangle. Is it the cable? battery? I don't know but without a fix I will have to return this beautiful watch.

I have been so reluctant to give up my Citizen Eco-Drive watch, especially for a 'smart watch'. I browsed for months and finally pulled the trigger. I have had my Samsung 4 40mm watch for a few days now and the first thing I noticed is....of course, it's yet another device that I have to worry about charging! This is not optimal however the battery does last through the day and I can charge it when I get home (around 10 or 11 hours). This watch calculated my ACCURATE weight quicker than most scales, I was honestly terrified at its accuracy. I got the app and watch programmed relatively easily, with the exception that I had to change my texting app to accommodate what was preprogrammed to the watch. My watch has told me I am overweight, I snore (IT RECORDS YOU SNORING), and reminds me that I am not physical enough. If you are looking for a motivational tool to help with your health....THIS IS IT!!!! I have increased my daily activities, water intake, and sleep time and do feel MUCH better....but this was NOT my plan when I purchased the watch, I just wanted to 'check it out'. Overall, I am impressed. I turned off the notifications as I don't need to be alerted to all 'Snaps' when you can't see them on the watch..... but continue to be amazed at the accuracy, dependability and motivation that I have found in this product!

This watch came needing an insane amount of updates. The watch was on the charger for two days straight. I thought it was because of all the updates. As I was wearing it, I noticed I had to charge it once a day. No biggie I thought. I thought it was because it needed a few more updates or something. Well fast forward a few months and now it the battery drains in less than a day. I had one update today and the update too 10 minutes. My battery went from 97% down to 40%. No update has fixed the battery issue. I'm guessing the watch came with a bad battery. I have the brightness almost all the way down. I have manual heart rate sensor on. I have everything on to try to make the watch battery last ad long as possible, but it still keeps draining faster and faster I checked my return window and unfortunately I am outside of the return window, otherwise I definitely would've returned this. I suggest not getting this or from this seller.

Esta funcionando bien.

Lo tuvimos que regresar. Leer bien las indicaciones de este proveedor. No lo recomiendo ya que el reloj no dura su pila y por el precio es mejor comprarlo directamente en tienda.
