EB484659YZ Verizon SCH-i110 Replacement Battery 3.7V 1500mAh

Verizon SCH-i110 Illusion — 3.7V Li-ion Replacement Battery (EB484659YZ)

This is a 3.7V, 1500mAh Li-ion cell for the Samsung SCH-i110 Illusion on Verizon's network. It fits the SCH-i110, Illusion i110, and Galaxy S i500. Same voltage, same connector, same BMS handshake as the original EB484659YZ.

• SCH-i110 and Illusion i110 compatibility: These models share the same battery bay geometry, 3.7V nominal voltage rail, and EB484659YZ BMS handshake. One cell covers all listed variants without adapter or modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the SCH-i110. The BMS communicated correctly with the phone's charge IC — no rejected charge events, no thermal flags during the test sequence.
• Fuel gauge recalibration on first use: After fitting a new cell, disable any fast-charge app or accelerated charging setting for the first complete discharge-to-charge cycle. This lets the phone's fuel gauge IC map the new cell's discharge curve accurately before applying higher charge currents to an uncalibrated cell.

Why the SCH-i110 reports wrong battery percentage after a cell swap

The SCH-i110 uses a fuel gauge IC that builds a discharge model from accumulated cycle data on the original cell. When you install a new cell, that stored model no longer matches the new cell's actual voltage curve. The gauge reads voltage and translates it using the old curve — so it reports 60% when the cell is actually at 75%, or vice versa. One full discharge from 100% to automatic shutoff, followed by a full charge, forces the IC to re-map against the new cell and corrects the readout.

Sudden shutdown at 20–30% on the SCH-i110

This is a voltage cliff issue, not a calibration error. Under load — screen on, active data connection, or a call — the cell's internal resistance causes voltage to sag below the modem's minimum operating threshold before the fuel gauge registers empty. The phone shuts down because the modem loses power, even though the gauge still shows charge remaining. Run one full discharge cycle without interruption; if shutdowns continue below 3.6V under load, the cell's internal resistance is too high and the unit should be replaced.
