oGoDeal Replacement Battery for Samsung Gear S3 Frontier(SM-R760) and Gear S3 Classic 3.85V 380mAh Battery SM-R770,BR760,R765 EB-BR760ABE GH43-04699A Battery with DIY Repair Tools

My S3 Frontier's OEM battery took a nose dive after 7+ years . . . I know, right? LOLI looked into possibly finally replacing my well worn S3 for something newer, but was immediately discouraged by the pricing. Then I thought "Why not replace the battery? It can't be THAT hard, right?"Well after watching some videos, I decided to give it a go - after all ~$15 bucks is MUCH cheaper than $400+ for a new watch. Plus I wasn't going to be out much of anything if the repair didn't work LOLI searched all of Amazon looking at reviews and checking out the various products. There were many to choose from, but I settled on this particular kit due to the quality of the tools and the other testimonials given by my shopping brethren.The kit showed up today and I hunkered down and got to work. The included tools (as I had assumed) were excellent and fit extremely well. Take your time taking the watch apart and you'll have no issues.The included picto-instructions did leave a little bit to be desired as they were not as clear as they could have been, but just watch some instructional videos and you'll get the gist of it.The only thing that I learned while doing this is: pulling off the back of the case will cause your watch to loose it's water resistance rating. The OEM seal is kind of like a glue? I wasn't really worried about it in my case because I'm sure that the water rating on mine had been lost long ago LOL.All-in-all, I am very happy with the purchase. Battery installed well. The tools were top-notch. This battery kit gave my 2017 S3 Frontier a new lease on life and kept it from contributing to the e-waste problem! 9.75/10 would buy again.

This review will be updated if and when there is some data on the new battery regarding longevity and capacity. It arrived at 62,% charge and after being installed in my R760 and 3 hours on the oem charger ,read 100%. The installation was relatively easy because the tools packed with the batter were of decent quality and were absolutely correct for the case "y" head screws and the motherboard Phillips screws. The plastic spudger and guitar picks were generic and worked. The metal opening tool was too thick and I opened the case using ,initially , a very thin knife blade. A review of youtube installation videos and the package insert instructions made the battery replacement manageable. So far the battery is performing well and it looks like I'll get a least 2 days use without recharge.This is with having fairly continuous drain with always on background wifi and Bluetooth but screen ( mostly) off. The oem battery lasted 4 years with nightly full charging. This time I'll try the charge to 80% discharge to 20% protocol. ( note: my old battery was swollen) Watch works like new and despite an hour without power ( despite bad battery , I kept the watch on the charger - continous green lite) all the settings ,wifi password, etc. were preserved. If I get more than a year on this new battery, I'm happy and will not downgrade the 5 star rating.Update: Got 4 days i.e. 96 hours down to 9% when I recharged. 3+ hours and green light and 100%.

Worked perfect for renewing my Frontier watch which was dying within hours of coming off the charger. Overall replacement was pretty easy. Took about 20mins start to finish. Watch operating like new and lasts 2 days on full charge.

At first thought the battery died but then found out it was the charger.

So far, so good. Took about half hour and patience 🙄 tools worked fine, but needed to use a bit of force on a few screws and back cover removal. Back to over 2 days battery life

The battery came with the attached power cable, two good screwdrivers of good quality build, a metal separator, and a plastic smudger with two guitar, like plastic separators. Let me caution you right off the bat at the beginning, TAKE NOTE, that the glue that attaches the original motherboard is significant and substantial. Critically important is to DO NOT PUSH any of the plastic or metal pieces in order to separate it without looking to see where the ground contacts are on the motherboard, which are the small little silver pieces in the picture. During the process of prying, the motherboard off, unfortunately, one of the grounding posts was dislodged off the motherboard, and the watch no longer functions with it screen being dark. The battery, however, was easy to install once you pry off the motherboard. The small ribbon cables must be separated gently with the provided pry instruments, from the motherboard (two small and one 1/2” one connected to the motherboard) preferably the plastic one. Once that is removed, carefully pry the motherboard off of the watch base. Again, be very careful where you put the separator, because you can easily knock the ground posts off the motherboard thus in activating your watch entirely. The product was a good product came well packed, it does everything it says it should, and I highly recommend it be used with a lot of caution. Excellent seller will buy again when the next watch a purchase needs a battery. Lesson learned be careful prying the motherboard.

I thought this replacement was going to be simple, but it WAS NOT. I thought that I broke the watch, but it ended up working. The small screwdriver stripped the screws connected to the battery also, which made it extremely difficult to remove. I probably won't be able to replace it again.But it is working great now that it's replaced.

Was able to repair a samsung watch that was said to be unrepairable. The battery was not staying charged. Used this replacement and was able to correct the issue. Just be aware that once you open the back of the Samsung watch it will not longer be water resistance.
