Samsung Galaxy S6 Edge EB-BG925ABE Replacement Battery 3.8V 2600mAh

Samsung Galaxy S6 Edge — 3.8V Li-Polymer Replacement Battery (EB-BG925ABE)

This is a 3.8V, 2600mAh Li-Polymer replacement battery for the Samsung Galaxy S6 Edge. It fits the SM-G925, SM-G9250, SM-G925F, and over 20 additional SM-G925 variants. Use this to restore a phone that no longer holds a charge due to a degraded original cell.

• SM-G925 variant compatibility: All SM-G925 models share the same battery bay geometry, flex connector pin-out, and BMS handshake protocol. The EB-BG925ABE part number covers the full range — regional variants differ in radio bands, not power architecture.
• Bench tested on actual hardware: We ran this cell in an SM-G925F and monitored BMS communication across charge and discharge cycles. The protection circuit engaged correctly at low-voltage cutoff, and charge termination fired at the expected 4.35V ceiling.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. This lets the Galaxy S6 Edge fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging sessions begin.

Why the Galaxy S6 Edge reports wrong battery percentage after a cell swap

The S6 Edge uses a coulomb-counting fuel gauge IC that builds its capacity model from the original cell's discharge curve. When a new cell goes in, the IC still references the old curve, so percentage readings drift — sometimes significantly. The fix is one complete discharge from 100% down to automatic shutdown, followed by a full charge to 100% without interruption. After that cycle, the IC resets its reference baseline against the new cell. Subsequent readings stabilise within one or two additional cycles.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below what the modem or display can sustain under peak load, even though the fuel gauge still shows charge remaining. The root cause is the fuel gauge IC firing a shutdown trigger based on a voltage cliff the new cell hits earlier than the old one. It is not a faulty battery — it is the IC recalibrating. Run two full discharge-charge cycles at standard charge rate, and the shutdowns resolve as the IC learns the new cell's voltage-to-capacity curve. If shutdowns persist past the third cycle, check that the battery connector is fully seated — a partial connection raises internal resistance and deepens the voltage sag under load.
