Review: Great deal with lots of features - 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.
Review: Battery life - 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.

## Questions & Answers

**Q: Does it take blood pressure?**
A: It does have a blood pressure /EKG app. The BP app has to be calibrated with a good cuff BP monitor. The accuracy is so-so. The app only works if the watch is paired with a Samsung phone, although there are hacks available to get the app working with other android phones. I have my Galaxy Watch 4 paired with my OnePlus 9 phone and the hacked version of the Samsung Health Monitor app. My evening BP using the Galaxy Watch 4 Health monitor app was 104/61. Taking my BP with my Wellue digital cuff BP monitor on the opposite arm was 115/64. Taking my BP with my Omron wrist cuff BP monitor on the same wrist as the watch was used was 115/65.  It's 122 using my Viatom Health Monitor Pro device. Overall the accuracy is "fair." The EKG function only looks for a-fib, but that is the most common arrhythmia. The watch also has a Sp02 function. I actually bought the watch because I needed it for monitoring my continuous glucose monitor (Dexcom  G6). Dexcom makes a special watchface/app for the watch that shows the current blood glucose level and has alert settings for lows and highs.

My only complaint about the watch is the battery life. I have to charge it twice a day - usually first thing in the morning while I'm having breakfast and then an hour or so before bedtime. I do wear the watch at night to track sleep apnea issues and to alert me if my blood glucose drops below a safe threshold.

**Q: What does country or origin mean?**
A: No if you have an iPhone get an apple watch

**Q: Is this  compatible with the A21?**
A: I'm not sure I found this information. Hope it helps
These devices will still have support on older Samsung phones but not the new Galaxy S21 series. According to a report by Galaxy Club, older Samsung smartwatches and fitness trackers will not be compatible with the Galaxy S21 series.Dec 5, 2022

**Q: Does it work for galaxy A13?**
A: It should.  It works via Bluetooth to Samsung phones.

### ⭐⭐⭐⭐⭐ Perfect for the average person
*by A***. on March 11, 2023*

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
