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

I was genuinely surprised at the quality of this product. I'm used to ordering things like this and getting a zip-lock bag with hand-written labels, but this came in good, retail packaging, the included tools were surprisingly high quality (I mean, not fantastic, but more than good enough) and after charging, my S3's battery life is right back to where it was when it was new.The instructions are okay, but I would highly recommend searching a youtube video to see exactly how it's done. I work in IT so pulling electronics apart and putting them back together is my bread and butter...and while replacing the battery isn't difficult, it IS extremely fiddly, and there are parts of the disassembly where you literally can't tell whether you need a little more force to get something loose or whether you're about to break something. (Removing the main board from its housing does feel like you're breaking it and if you pry it up from the wrong side it would be REALLY easy to break the battery cable).I can highly recommend this kit, I'd just also recommend spending 20 minutes on youtube so you'e sure you know exactly what you're doing before you even touch a screwdriver.

Completely saved my Samsung S3 classic watch! Was down to 10 hours battery life on my original battery and tried this to see if it would work. A bit fidgety to install but all parts and tools are supplied and I managed it in 20 mins. A wee tip is to do the job on top of a piece of white paper to see all removed parts easily as the screws are small. Followed the instructions supplied with the kit but also watched a few online vids to help before attempting.Watch is back to 2 day battery charge! Excellent stuff. Was thinking it was for the bin but this has saved a decent watch as the samsung were charging crazy money to do this small job.

The battery on my Gear s3 frontier died after the watch got wet whilst running. This kit has everything you need including clear instructions. I recommend watching some YouTube clips as I found an easier method on there. The battery life is about 1.5 days which is not as good as the 2 days that I got from the original battery but for 18 quid I think that is pretty good.

For a while now I've been getting less and less out of watch and no amount of charge/recharge cycles or resets seems to make any difference.Had to travel to UK, which meant being stuck in a hotel isolating due to travel restrictions, this kit was exactly what I needed to replace my battery. The kit contains all the tools you need and the included instructions are good but I would watch couple youtube vids so you know what you're getting into. It is not hard, but is fiddly.As mentioned this will break waterproof seal, not a big deal since watch would be useless anyhow but be nice if the kit contained new seal, or a little silicone tube or something, however not a deal breaker.Took about 15/20 mins to replace, mostly as I was being very careful and heres a tip when trying to prize back off:.. Using the metal tool, use the watch strap as leverage against the case until it breaks seal, then go in from edge as per instructions. I found this much easier than trying to get tool in-between halves to open.

Like most reviewers, I too was a little concerned about replacing the battery, especially as doing so breaks the waterproof seal.This product came well packaged and with fairly detailed instructions - there are numerous YouTube videos which I suggest watching-I agree with reviewer N, that commented on the metal utility tool. A little too thick, and with the central protective padding quite slippery, I found that my hand slipped several times in attempting to remove back case resulting in a cut finger.That being said, and not being super delicate by nature, I have replaced the battery in the watch. It powers on and the watch life is back to 2 full days light use, and a full day of heavy use. The only downside is the bezel ring doesn’t scroll anymore, although it will still wake watch. This is more likely to be my workmanship and something not quite connected. Overall money well spent and definitely given a new lease of life to my watch.

This product is relatively cheap if you're prepared to give it a go. However, the materials used for the tools are of very low quality. The driver head rounded off on the first use. And the metal strip used to separate the back of the watch was so sharp I sliced my hand and fingers. I had to tape this with electrical tape to prevent further injuries. I messaged the seller regarding the screw driver but no response. I had to use my own tools. Battery seems OK for now. But just get your own tools!

Got this next day delivery as my watch kept randomly turning itself off. After a watching couple of videos on YouTube I had a go. It was fairly easy if not a little fiddly, just being careful not to damage anything as I went. Had it in a couple of days now and so far so good.UPDATE:Had it about a week and a half now and all of a sudden the watch wont turn on. Was working great up until then. Could be a dud battery.

Had my watch nearly 4 years but battery was had serious problem and would only last a few hours, even on power saving mode. Took it swimming and it had a melt down, kept rebooting and screen wouldn't turn on except for rare occasions, basically watch was ready for the bin. Though I'd give this a go and glad I did. Watched a you tube video and found it very easy to do in about 2 minutes with everything included in the kit. Watch now works brilliantly. The newer versions don't do anything my watch doesn't so didn't want to spend 300 quid on a new one. This is well worth a go at 15 quid if the alternative is to through your watch in the bin and buy a new one imo.
