It was so memorized that it would only power for about 8 hours. I thought about buying a new watch but I noticed that I could buy this complete replacement battery kit, tools included, for less than $25 all in, and I thought, what the heck. Plus I'm cheap so there's that. It's nice that there is an instruction pamphlet too, but really, there are any number of Youtube videos on how to replace the battery that are more helpful. It wasn't hard to disassemble the watch but you have to go slow and be careful because the ribbons are very thin and if you break one you're dead in the water. Being very careful I was able to preserve the super-thin gasket that keeps the case water resistant, so hopefully the reassembled watch will not die the first time it gets a few drops of water on it. The entire operation took a couple of hours. But I'm sure if I had to do it again it would go much faster now that I know how it works. And the result was near-miraculous. Suddenly I seem to have a new watch. I only used 20% of a full charge on the first day of wearing it. I'm not expecting this to last another three years but if it gets me a year, it will be a win. Overall, the product is good. The battery works, the correct tools are there, and it came pretty darn quickly considering there's a pandemic on. Review: Watch a how to video online first to ensure you are prepared to do the install. - 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! ## Features - 1. 🔋 Premium Replacement Battery – Restore Your Gear S3 Is your Samsung Gear S3 Frontier battery draining faster than usual?

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! ### ⭐⭐⭐⭐⭐ A Micro-surgical Transplant Success! *by F***N on December 19, 2019* I will give this product and my S3 both 5 stars! But please read on... I really like my Samsung S3, I wear it almost everyday and everywhere I go. Some of my favorite features include music control, heart-rate monitoring, the altimeter and seeing messages real-time without ever touching my phone. So my S3 Frontier is ~30 months old now and battery life was down to about 6 hours on a good day. After some quick searches I came to the conclusion it was time for a new battery. I ordered this battery kit, since it looked like a pretty good deal: a new battery and tools to open my watch. However, be warned that your S3 is not a consumer-serviceable product. I have good eyes, steady hands and consider myself above-average technically inclined. I've burrowed deep into my Jeep engine to replace an oil-pressure switch, installed a transfer switch to my house's electrical supply and I've pieced together many computers. All child's play compared to swapping out batteries for this watch. I thought I was going to destroy my watch during the process of replacing the battery. The instructions (and available YouTube videos) are a great start, but downplay the challenge. The screws are hard to turn without stripping the heads. The tiny FPC (Flexible Printed Circuit) cables are almost impossible to work with. And the threat of ESD damage to your watch is daunting while performing the transplant. Yes, I managed to do it. I powered the watch up briefly before reassembling everything, since I was worried I damaged or miss-aligned one of the micro FPC cables. Success! And I closed the patient back up. My battery life is now showing about 60 hours. I'm a happy camper. If you are still planning to proceed, wear an ESD strap, remove dirt build-up from in the screw heads. Take close-ups of how the battery is attached, before removing it. Pay attention to how the FPC cables are attached and aligned. If your 1.5 triangular tool starts slipping (like mine did after loosing the first two screws), grind a millimeter off the tip and it will grab again. Take your time, some steps (like taking the back cover off) will take more force than you think, but it can be done. ## Frequently Bought Together - 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 - Emilydeals for Gear S3 Charger, Replacement Charging Cradle Dock for Samsung Gear S3 Classic/Frontier Smart Watch (Black) - V-MORO Compatible with Samsung Gear S3 Frontier Bands/Galaxy Watch 3 45mm/Galaxy Watch 46mm(2019),22mm Solid Stainless Steel Metal Business Bracelet Strap Black(Not for galaxy watch 4 classic 46mm) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/136188625-ogodeal-380mah-battery-for-samsung-gear-s3-frontier-classic](https://www.desertcart.is/products/136188625-ogodeal-380mah-battery-for-samsung-gear-s3-frontier-classic) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-09-04*
