Long lasting! *by on Reviewed in the United States April 16, 2025* Improved battery life and the easiest to install. It’s capacity was much longer than the old one and even came with a tool kit. Good value for the money I’d recommend ### ⭐⭐⭐ working perfectly *by on Reviewed in the United States August 21, 2025* Very good quality 100% recommended 5000 mah real The truth is that it worked wonderfully for me, it lasts two days of use ### ⭐⭐⭐⭐⭐ Now my S21 lasts all day at work. *by on Reviewed in the United States October 14, 2025* I don't know when I ordered this, cuz I can't see the date right now from my mobile. But I'm pretty sure it's been 4 or 5 months.This battery now allows my phone to last my entire 8-hour shift doing pest control. I use my phone every 10 to 20 minutes... And I used it for navigation all day. I normally keep it plugged in just to keep it topped off at 80%, But I have gone a whole day without plugging it in just to see how long it lasts and it does the job.I do a lot of phone repairs so replacing the battery in my phone was no big deal. If you've never done it look up a YouTube video it's pretty easy. A hair dryer will work, a heat gun will work better. ## Frequently Bought Together - ElephantStory Battery for Galaxy S21 Ultra, 5000 mAh Battery for Samsung Galaxy S21 Ultra 5G SM-G998B/DS SM-G998U with Repair Kits - PHONSUN Back Battery Door Cover Adhesive Tape for Samsung Galaxy S21 Ultra 5G SM-G998U G998U1 G998 (Pack of 2) - Perzework Rear Back Glass Replacement for Samsung Galaxy S21 Ultra 5G with Pre-Installed Adhesive and Repair Tool Kits (Phantom Black) --- ## 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.jp/products/682834325-elephantstory-battery-for-galaxy-s21-ultra-5000-mah-battery-samsung](https://www.desertcart.jp/products/682834325-elephantstory-battery-for-galaxy-s21-ultra-5000-mah-battery-samsung) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-16*
