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: My Gear S3 Classic got a few more years of life from this. - My watch (Samsung Gear S3 Classic) got new life with this battery. I'm not sure if it's actually 520mAh, as the device reports it to be the same as the previous, but the watch lasts pretty well again. Hasn't cured the watch of sometimes dieing after half a day, but I've come to understand that this is the watch messing up, and not the battery. I still love this watch, though. ## Features - {COMPATIBLE MODEL}: Our battery only for Samsung Gear S3 frontier (SM-R760), Samsung Galaxy Gear S3 Classic R770, R760, R770, BR760, R765, SM-R770 please confirm your watch model before placing your order.
