oGoDeal 380mAh Battery for Samsung Gear S3 Frontier/Classic

The install takes a little bit of doing and the parts are small so you’ll want to be careful not to pull any crucial wires out or lose any of the tiny screws. After complete you can charge fully and so far it has been working and still at 90% power after almost an entire day. Seems to be a winner!

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%.

My Samsung Gear 3 Symptoms: It would seem to charge to 100 Percent, but would not tun on. Watch was two years old, so I was hoping it was the battery. It was. The install was a little frustration because I had issues getting the back cover off. The 1.5mm Y screwdriver that comes with the kit didn't do a great job of loosening the screws. Fortunately, I had a second bit kit that had the same size. I was then able to unscrew the back easily, so I am not sure if anyone elase will have the same issue. Once you get the back off, there are a couple of tiny Phillips screws and three ribbon cables that need to come off. You then need to carefully pry the thin cover of the internal casing off to expose the battery and the fourth ribbon cable. You should be able to do this if you take your time. It's not overly complicated but requires a steady hand to get the tiny ribbon cables reconnected. I am happy to report the watch is working perfectly now. Good luck with your repair!

My Samsung Gear S3 Classic was dying quickly. It had already been going down hill, because it was only lasting 8 hours, instead of the 14+ hours that it had, when I bought it. Suddenly, within 3 days, it went from lasting barely 8 hours, to only lasting 2 hours. That's when I ordered this kit. If you're handy, this install goes fairly well. The issues I had, were outside of these tools. The back would not pry off, even though the tool was lifting it. It had become 'stuck' to the watch, and took a will to finally get it to release. Once it was off, the install was fairly easy (watching YouTube videos, to help). Keep in mind, these ribbon cables are small, so while the tools are small and work well, you'll need to be able to see/work with small connections. Once back together, my watch was once again showing over 14 hours of life! It's been a couple weeks now, and still going strong. My boss ended up getting the same kit, because his watch had died, last month. His watch back did not stick, like mine, but he had issues with his screws not releasing. His had some sort of lock-tight on the screws, which made his removal difficult in a different way. Again, not the fault of this kit. The screw driver worked fine, but the screws wouldn't budge. Eventually he was able to work them loose, tapping with a hammer (I would NOT recommend). His watch came back to life, and he can once again go a day without it dying.

I purposely waited to write this review until I had some time on the battery, as some of these after-market watch batteries can be low quality and fail quickly. That is NOT the case here! This is an excellent bit of kit. Battery was installed in the Gear S3 watch in November 2019. It is now mid-June 2020, and it is still going strong. Even after eight months, I still see 75-80% battery life left after a full day of use (including an hour every night of S-Health use). The stock battery it replaced, which was several years old and puffy, wouldn't even make it 8 hours before it was dead. Changing the battery is not very difficult, although it is a bit fiddly and will cause you to ponder how they are able to mass produce these watches. The tools it comes with are surprisingly good quality: the screwdrivers have well machined aluminum handles, and it includes a good spudger that has come in handy several times on other projects. The instructions are quite good, with just a few areas that are just a touch confusing (but easy to figure out once you're in there), and clear warnings on areas to be careful. If your watch battery is not holding a charge anymore, I highly recommend this kit. The quality is excellent for the price, and the battery has held up very well.

Fantastic replacement for my irreplaceable Gear S3 Frontier! I don't want to lose my S3 Frontier due to the MST technology for Samsung Pay and this was a lifesaver for keeping my watch alive! The installation was fairly simple and it took me less than 15 minutes. Additionally, the battery life is reminiscent of the OEM battery life when it was new. If you're unfamiliar with small electronics repair, this might be daunting for you. It does come with tools in the box which are of pretty darn good quality instead of plastic tools. It does also have instructions if you need them, although they're not always extremely clear. I'd highly recommend looking up a few videos on YouTube to help familiarize yourself with the repair. I'm familiar with small electronics so my 15 minutes for repair might not be typical of your experience. The battery installation was a breeze. The battery connectors are the right size and the battery is a near OEM replica. The only drawback for the battery is the lack of adhesive on the battery replacement vs the original. I thought this would cause some rattling but so far so good after a few weeks. The battery life is superb and just like when my battery was new from OEM. My watch know lasts multiple days without needing a charge, even with numerous notifications. Revive and save for precious Gear S3 with this option!

The price was good, but two of the included tools were useless which made the process not go as smoothly. First, the Y screwdriver has too sharp of a point to actually grab the screws. I had to file down the tip before it would actually grab the screws. Also, the metal pry bar for opening the case was too soft and I had to use a sturdier pry tool from a separate watch battery replacement kit I already owned to pry open the case. Once I got past those issues, everything went smoothly. The factory battery had started ballooning so it was definitely toast. After only getting a couple of hours out of the original battery, it's nice having a battery that will last more than a day again.

I was reluctant to purchase a battery for my Samsung Galaxy Gear 3 classic. This watch was a refurbished watch from Amazon, and I was highly disappointed in the battery life after six months of usage. By the time I got to Christmas of 2021, my battery barely lasted 5 hours. In January, it would randomly shut off and not boot on a 80% charge. I grew frustrated and nearly gave up until my father-in-law suggested I purchase a new battery from Amazon. I did just that and I would suggest to not listen to the negative reviews on this battery. The instructions were easy to follow and I replaced my original battery in a matter of 20 minutes. The included screwdrivers and tools made getting the case open and removing the batter easy. Remember to be careful as the wires are very thin and you don’t want to break them. But if you go slow and easy, you’ll do just fine. I’ve had this battery in since May 7th and I couldn’t be more pleased. I pull the watch off in the morning and when I go to recharge the battery in the evening I often have 70% battery left after a full day’s use. Heavy usage the batter will drain to 55% by evening. Not bad for a replacement. I can easily get nearly 2 full days on one charge. Highly recommend.

The battery came with all the tools needed to install it and take hurt the watch. They mistakenly put instructions for replacing the battery for an Apple Watch 4 in the box. Nevertheless I just googled YouTube for instructions on replacing the battery and a couple of great videos came up to guide me. You have to be very careful with four small ribbon connectors but just go slowly. It's like having a new watch again now. I'm sure the battery would last for almost 4 days if I ran it down to nothing! It works so well It's very impressive... Maybe better than the original battery in the watch. Highly recommended, but you have to be very careful in the installation that's not super simple!

The kit is perfect. Includes all the tools needed and good instructions. I recommend watching a video on youtube or something the pictures are not great on the instructions. Highly recommend for anyeone having battery issues with their samsung gear s3 classic.

The battery is great and is performing well. The package was missing the opening tool so made the opening of the watch quite hard as I had to pry it with a small screw driver. Everything else was fine, instructions easy to follow, although I complemented them with a youtube video just in case.

Had my S3 for some years now, Battery barely lasting 2 day. Replacement was easy and all the tools were perfect. S3 has 4 days worth of battery now. Back to first day I got it.

Did not work
