Replacement Battery for Samsung Gear S3 Frontier and Gear S3 Classic, (𝐒𝟑 𝐅𝐫𝐨𝐧𝐭𝐢𝐞𝐫/𝐒𝟑 𝐂𝐥𝐚𝐬𝐬𝐢𝐜) SM-R770, BR760, R765 EB-BR760ABE GH43-04699A Battery with DIY Repair Tools

I take a lot of stuff apart... first time took less than 2 minutes(getting the back off can be hard) but a little heat helps, or a lot if you also have to replace the back glass already...once you get the back off and disconnect the 3 connectors and 2 Phillips head screws... just be careful of the rear ribbon cable and consider the battery will stick if humidity got inside the case. I did not use any of the tools that came with... tiny phillips head and 1.5x30mm Y head, metal wedge, pry tool, and razor blade... I only used a torch, a razor blade, and xaoimi screwdriver set. after a few weeks of testing, there is a WORLD of difference this made for my unit... previously holding a charge for 4 to 16 hours. I got a very good battery it appears, turned on @ 50% charged. charges up and lasts all day like it did 6 years ago in xD if only my samsung "Galaxy W 'phone' " lasted as long (the ONLY SAMSUNG tablet that has EVER worked with this watch)... shame they purposely make tablets incompatible with watches after 2015 ... among the many reasons this will be my last samsung watch.Update: using gear dashboard wallpaper, and ALL motion activation, nfc, and touch activation all turned off. Motion tracking for sleep, 6 hour weather updates, notifications and sound all turned on in greyscale mode with the brightness all the way down on 10 second sleep timer... It would last 4 to 16 hours (depending on the charger)on the old battery up until the back broke... Then I would get maybe 4 to 6 hours, now; with the new battery, I get over 4 to 6 days.

When you do this, sit down get a big clean location to do it.. get a GOOD bright light, go look at a video prior to doing it to see if you want to do it.. and if you do it.. understand it has TINY parts.. tiny screws.. tiny wire connections.. go slow.. take your time.. and if you have magnifying glasses have them handy.. you will need them :)with that said.. it works great. when I got it installed the watch was at 70% charge off the bat.. so it really was nice.. to not have to trash the watch or try and find someone to repair them and charge who knows what.

This is what came in the package. It took two weeks to arrive and the primary screwdriver to open the watch is not included (Y screw driver)

My original Samsung Gear 3 Frontier watch battery was only giving me 60% on a full charge after 6+ years. I contemplated pitching the watch and purchasing a newer model, but for only $16 I decided to try replacing the battery first. My watch went from a 4-hour battery life to over 40 hours. The YouTube video was a little difficult to follow, and some of the screen shots could be a little larger. But, I was able to replace the battery and get everything reassembled, and the watch runs like new. Thank you

Have had my Samsung watch for years. Love the watch, but the battery life has gone down to less than 30 minutes with minute use. Liked at a new watch but decided to try replacing the battery.Received this kit and found a YouTube video showing how to do the swap ... you really should do that as well. Without that video I 100% would have messed something up.Replaced the battery and charged it for ~ 8 hours. Used it all day today, streaming music, etc, and its still at 75%. Looks like I'll get close to 2 days on a single charge.From 30 minutes to 2 days is impressive for what this costs. 5 stars for sure.

Helpful directions on installing the battery.

Takes awhile to dismantle and put back together but there are numerous YouTube videos you can watch and pause to get through the process.The only negative I had was the kit.There was supposed to be a Phillips 1.5 mm screwdriver aka #000 and it turned out to be a "Y tip".Had to get my optical screwdrivers out and fiddle-fart with it. Finally got the screws removed and reattached.Go slow and follow the YouTube directions.
