Samsung S21 Battery Replacement Singapore
Is your Samsung S21 battery draining too fast? Certified Phone Repair SG offers professional battery replacement with Grade A batteries, same-day service, and a 90-day warranty. Walk in to any of our 4 outlets — no appointment needed.
The compact Galaxy S21 has the smallest cell in the S21 range at 4,000 mAh, so wear shows quickly — a new Grade A battery gets it back to a full day.
About the Samsung S21 Battery
The Galaxy S21 (SM-G991) launched in January 2021 with a 6.2-inch FHD+ Dynamic AMOLED 2X display at up to 120Hz, an ultrasonic in-display fingerprint sensor and a 4,000 mAh battery supporting 25W wired, wireless and reverse wireless charging.
With a smaller battery driving a high-refresh screen and 5G, an ageing S21 often needs a midday top-up, runs warm on the charger or switches off before the battery reads empty. A replacement restores normal battery life, and your data and fingerprint setup are left as they were.
