[520mAh] Battery for Samsung Gear S3 Frontier(SM-R760) and Gear S3 Classic, (2025 New Version) Upgrade Replacement Battery for SM-R770, BR760, R765, EB-BR760ABE, GH43-04699A with DIY Repair Tool Kits

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 Amazon 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.

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.

I really can’t say enough good thing about Mothcas’s matte 17 PM screen protector. I’ve always been someone of a connoisseur of matte protectors because they by far, prevent fingerprints better than any other options out there, but this one far exceeds any I’ve owned in the past! You tend to deal with some image degradation when you go matte, but they appear to have corrected this somehow and my picture quality is spot on. Pros: The image quality is superb. The fit is flawless. The application accessories work like a charm compared to others. They appear to be scratch and crack resistant unlike many others at the same price point. They are the overall matte pick…assume me for good reason! Comes with two protectors, which is always a plus. Cons: While their application accessories are well thought out, it does take a few tries to figure it out, which led to my protector being slightly lower and not lining up straight with some glue not adhering at the bottom.

I have an old Samsung Gear S3 Frontier watch and after years of wear, the battery would no longer charge. I took it to a repair shop that does electronics repair. They said the price of replacing the battery would be about $125 but their problem was an inability to get the battery I needed. DUH? I watched a couple of YouTube videos and then ordered this replacement battery and kit for less than $20. Replacing the battery was not rocket science. I am a 71 year old woman and I managed. My watch is now as good as new.

Does not hold charge for more than a few hrs.

Product was great, however the watch repair shop i took these tools to to fix my watch broke my watch. Go figure, I provide the tools, battery and watch and they break the watch 🤣

The pry tools are garbage and the screwdrivers were pretty awful as well, felt like I was stripping the screw almost immediately. Ended up using my own precision set to get the watch open. The battery extraction tool was helpful in removing and reseating the battery connections and the battery worked great until I traded in the watch.

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.
