EB484659YZ Replacement Battery for Samsung SCH-i110 3.7V 1200mAh

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

This is a 3.7V, 1200mAh Li-ion cell built to fit the Samsung SCH-i110 and Illusion smartphones on Verizon. It replaces OEM part EB484659YZ when the original cell can no longer hold a usable charge. Fits the SCH-i110, Illusion, Illusion i110, and Galaxy S i500.

• SCH-i110 and Illusion compatibility: These models share the same battery bay dimensions, 3.7V nominal voltage rail, and connector pinout, so one cell covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the SCH-i110 platform. The BMS accepted the charge handshake on the first connection, and the protection circuit tripped correctly at the low-voltage threshold without forcing a hard shutdown mid-use.
• Fuel gauge recalibration on first use: After installing a new cell, disable fast charging if your charger supports it and run one complete discharge-to-charge cycle. The SCH-i110's fuel gauge IC is calibrated to the old cell's discharge curve — one full cycle lets it remap against the new cell before you rely on the percentage reading.

Sudden shutdown at 20–30% on the SCH-i110 after a cell swap

This is a voltage cliff issue, not a capacity problem. When the modem radios or display fire at high load, the cell voltage drops sharply below what the fuel gauge IC predicted based on the old cell's discharge curve. The phone's protection circuit sees that voltage drop as a critical low and cuts power before the reported percentage hits zero. One full discharge-to-charge cycle after installation lets the fuel gauge relearn the new cell's curve and stops premature shutdowns.

Phone warm near the battery compartment during first charge after replacement

A freshly installed cell with no prior charge history has higher internal impedance than a conditioned cell. The charge IC on the SCH-i110 applies the same current profile regardless, which creates more resistive heat in an uncalibrated cell. This is normal on cycle one and typically resolves by cycle two or three as impedance drops. If the phone stays warm past the third charge, check that the battery contacts on both the cell and bay are clean and fully seated.
