Owners usually describe the same slide. The S21+ used to end the day at 30 percent, then at 10, and now it needs a charge after lunch. That is charge cycle wear, not a fault, and every battery does it eventually.
The fix is an original Samsung 4800mAh battery fitted by our technicians in Umhlanga. The price on this page includes the battery and the fitting together.
Signs you need this repair
- Used to last all day, now barely makes mid-afternoon
- Percentage freefalls once it gets below 30
- Random shutdowns with charge still showing
- Back of the phone warms up doing nothing much

Common questions
Why not just use a power bank instead of replacing the battery?
A power bank treats the symptom. A worn cell keeps degrading, voltage sag causes random shutdowns, and in rare cases a failing battery swells and pushes against the screen and back glass. Replacing it deals with the cause, and you stop carrying a charger everywhere.
Is a swollen battery urgent?
Yes. If the back glass is lifting or the screen is bulging, stop charging the phone and bring it in. A swollen cell is under internal pressure, and pressing on it, puncturing it or charging it makes things worse. We remove it safely and fit an original battery.
Does the replacement battery match the original spec?
Exactly. It is the original Samsung service battery for the SM-G996B at the full 4800mAh, with the same protection circuitry and support for the phone's fast charging. As an authorised centre that is the only battery we fit, and fitting is included in the price shown.
