Review: Awesome fit - I've been in the market for a smartwatch for a while. I am very picky about the design and functionality. I love the look of the Samsung gear s3, just something about being able to spin the bezel reminds me about some of the watches I had when I was younger. So I was super stoked to find one one here on desertcart in the renewed section. Unfortunately this is an older model and was in acceptable condition but a steal at just 36.00. I noticed that the battery had a hard time keeping a charge and it would die within a few hours. Looking for accessories I found this replacement battery. It was pretty cheap and came with the tools to change it. It was not too difficult and took about 20 minutes start to finish to change. The hardest part for me was getting the back off without damaging the wires. Then putting it back together correctly. I would recommend taking some pictures before and during the process just to make it easier putting it back together. There is nothing solder it all just snapped back together easily. Put it on the charger and now it works better then ever and being 520ma the battery last almost twice as long. The only additional tools I use was a flat head screwdriver to gently pry the back off and a magnifying glass to be able to see the wire connections better. So now I'm into my watch for about 50bucks and absolutely love it.
Review: Good battery! - Easy replacement. I watched a video on you tube. New battery lasted just under 3.5 days. Been consistent battery life over 2 charge cycles thus far. Ill update if that changes over the next couple months.

### ⭐⭐⭐⭐ Good replacement battery
*by B***N on November 7, 2025*

Battery is good charged up fine and last on average 3 and a half days. Was not easy to install because the cable on the battery didn’t fit the alignment peg in the watch, the hole was to small but it still worked. It claims to be the same size as the original battery but the description says 430 mAh and not 520 mAh but I couldn’t tell any difference. This kept my watch alive so I’m happy!
