Watch lasts almost 2 days. Great buy.Replacement was fairly easy with the instructions and video. I'm on my third drain and charge. Put on my watch lay night at 100%, put in sleep mode, woke up and it's at 22%. Original battery would only drop 10-20% overnight in sleep mode. Not sure if the replacement battery is faulty or it still needs to have me full charge to nearly drained cycles. So far not impressed. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Easy Peasy *by R***N on Reviewed in the United States on August 2, 2023* Battery replacement is pretty straight forward, took about 30 minutes. There are a few "how to" videos on YouTube that makes the process much easier.The suppiled tools are just okay. The phillps screw driver didn't do the job so I used a better quality one I had from a few phone repairs. The razor blade was useful for opening the back by using it long ways along the groove to separate the back shell. Battery longevity has not been tested yet as I just installed it. ### ⭐ 1.0 out of 5 stars The Battery did not work. *by P***S on Reviewed in the United States on October 25, 2023* The battery did not work, I called Samsung and was told that the battery needed to be replaced, I ordered this battery and the watch did not turn on, it flashed a green screen just like with the original dead battery. --- ## 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.id/products/473083265-44mm-active-2-battery-replacement-for-samsung-galaxy-watch-eb](https://www.desertcart.id/products/473083265-44mm-active-2-battery-replacement-for-samsung-galaxy-watch-eb) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-04-25*
