Battery for Samsung Gear S3 Frontier Battery 580mAh(SM-R760) 2025 Upgrade High Capacity, Replacement Battery for SM-R770, BR760, R765 with Professional Repair Tool Kit

I recently bought a gear s3 but it came with a bad battery which won't hold a charge so I needed a replacement. Bought this one because of the price. It was not that hard to Install. It's now been a month and its still working flawlessly and the battery is not expanded. It lasts about 2 days with always on display. Its a good battery.

Battery died in my S3 several years ago, I had just kinda thrown it in a desk drawer and forgot about it. Ran across it a few weeks ago. TL;DR is I decided to grab a batter and see if it would fix it. Took like 20 mins to change the battery out, worked immediately. Battery was full on delivery. Finished installing the battery 3 days ago, and the charge level as of today is 25%. So I guess it works.Included tools are fine. I couldnt get the back door off w/ just the little plastic guitar pick thingy, so I just used a razor blade really carefully to get it started a little, then finished with the pick. Problem solved. Just take your time disconnecting & reconnecting the leads once you get it open, not a whole lot to it.Bought this one because it was the cheapest I found. Mixed reviews so I guess YMMV, but the one I got seems good to go.

Easily installed this battery to replace the original 380mah battery which until recently, would keep a functioning charge for 3+ days. The original battery was old and suddenly would last ~6 hours.This new battery is supposed to be high capacity 580mAh. After installation, the watch displays the battery as a 380 mah battery, not 580mah. This new battery lasts 8 hours max! Faulty new battery or False product?

I do work similar to this. So I thought this would be easy no it's not. But after I got it in the battery worked great for two days. But when I went to recharge it it wouldn't take a charge I'm going to try buying a new charger. About my charger used to work

Brought some much needed life back to my Samsung galaxy gear s3 frontier. Instillation wasn't too hard if you've ever replaced electronic parts before. The hardest part was getting the back of the case off. The little spudger tool they provided was of no help. Something much sharper is needed. I ended up using a razor blade.

You will need to find a video on YouTube on how to change it, but the tools were helpful and the battery works well so far.

Easy to replace just make sure you have a magnifying glass. My S3 now works like it was new. I don't remember the watch face ever being this bright.

installation was easy enough, and now I can get a few days out of my watch instead of like, 10 hours
