SAMSUNG Galaxy Watch 4 Classic 46mm (Open Box)

First off, the watch I purchased was the Samsung Galaxy Watch 4 Classic (46mm) Bluetooth Edition. I love Samsung products. I've only ever had Samsung smartphones (S4, S7, S9, and currently an S21). Amazing quality and battery life for most of those phones. When I heard about the Samsung Galaxy Watch 1, I wanted to get it so bad. I got it for Christmas in 2020. I still have that watch to this day, and the battery is going VERY STRONG on it! I slept in bed with it on and when I woke up it was only down to 98%! Without charging it, I went to work and 8 hours later the battery went down to 78% (with AOD and 10 minute interval heart rate monitoring). Such an amazing watch and battery life. So, getting to the point, I ordered this watch (thinking it was going to be an upgrade to my original Galaxy Watch... And don't get me wrong, it definitely is an upgrade with certain features (health monitoring, Wear OS instead of Tizen OS, and it just looks more modern). But that battery... It is one of the worst batteries I've ever had in a Samsung device. It didn't even last me a full day's charge under normal use (AOD with 10 minute heart rate monitoring). I went to sleep with the watch, and when I woke up with this watch the battery was down to about 78%. Already not a good start. So I went on with my work day, with the same settings as my original Galaxy Watch (almost the same AOD, and 10 minute interval heart rate monitoring) and the watch didn't even last me the entire work day. It died at about 6.75 hours. This is already a deal breaker for me, but I had two more problems with this watch. The second problem I had was that the rotating bezel on the Classic edition was very loose, and made a metal "clinking" noise when I tapped on the top of it (as there was so much of a gap between the watch and the bottom of the bezel, when I tapped it, it came in contact with the watch). I didn't think much of it, but then I started reading more about it and most people say it's a defective watch and that you need to get it replaced under warranty to fix it. The third problem I have with this watch is that the Galaxy Wearable app would fail setup 90% of the time, I had to restart the watch probably 10 times and reinstall the Galaxy Wearable app at least twice and remove all my existing wearables to get it to finally link. Overall, I would recommend this watch if you don't plan on using it for most of the day, and are fine with having it on a charger for the majority of it's life. I personally have returned the watch and I'm going to be buying the Samsung Galaxy Watch 5 Pro to see if it is any better in terms of battery life (it should be seeing as it's 61% larger!).
