Replacement Battery for Samsung Gear S3 Frontier and Gear S3 Classic, (𝐒𝟑 𝐅𝐫𝐨𝐧𝐭𝐢𝐞𝐫/𝐒𝟑 𝐂𝐥𝐚𝐬𝐬𝐢𝐜) Battery 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.

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)

Helpful directions on installing the battery.

The phillips screwdriver was flimsy and useless. You will need a decent quality #00 phillips for the two interior screws. The tri wing screwdriver for the 4 exterior screws was not much better, but I was able to make it work. The rest of the tools included in the kit worked very well. Most importantly, the battery worked great after I installed it and now lasts over 2 days on a full charge. Make sure you watch a video, it's a tricky procedure.

Delivered and works as sold

The tri tip screwdriver was too big. Had to order the Y000 screwdriver. Waiting for it to arrive to see if the battery works on my Gear S3 classic.

I ordered 3 battery kits and this was the highest quality kit overall. I didn't expect that because it wasn't the most expensive! The battery is the higher capacity version and fits perfect. The tools were high quality and I had no problem getting the screws out with the provided screw drivers. The only thing that was a little tricky for me was separating the back cover from the watch. I ended up using a kitchen knife and that finally broke it loose. I just need something with a sharper edge to fit into the gap between the case back and the watch. Check You Tube for replacement instructions and it's a breeze. I would definitely recommend this battery replacement kit over all the others!!

The Phillips screwdriver was too big for screws. Had to use old Phillips screwdriver I had for glasses. Worked better. Watch didn't charge and I followed every hectic step carefully. Not as easy as it seems. Better off getting new one, or refurbished cheaper. Waste of money!
