Samsung Galaxy S7 EB-BG930ABE Replacement Battery 3.85V 3000mAh

Samsung Galaxy S7 SM-G930 Series — 3.85V Li-Polymer Replacement Battery (EB-BG930ABE)

This 3.85V, 3000mAh (11.55Wh) lithium-polymer cell replaces the original battery in the Samsung Galaxy S7 and its SM-G930 variants, including SM-G930A, SM-G930F, and SM-G930P. It matches the OEM dimensions at 87.90 × 38.75 × 4.90 mm, fitting the chassis without modification. The replacement targets devices that have lost charge capacity, experience sudden shutdowns, or no longer hold power through a full day.

• SM-G930 variant compatibility: The SM-G930A, G930F, G930P, and related models share the same battery bay geometry, connector pinout, and BMS handshake protocol — all use EB-BG930ABE or its equivalent OEM cross-references (EB-BG930ABA, GH43-04574A, GH43-04574C).
• Bench tested on actual hardware: We cycled this cell through charge and discharge on an SM-G930F unit. The BMS accepted the charge IC handshake without fault codes, and the protection circuit responded correctly to both overvoltage and undervoltage cutoff thresholds.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC pushes high current into an uncalibrated cell — skipping this step causes erratic percentage readings for the first several cycles.

Sudden shutdown at 20–30% on the S7 after a cell swap

This is a voltage cliff problem, not a capacity problem. Under high-current load — active LTE, screen at full brightness, or GPS — the new cell's terminal voltage drops faster than the fuel gauge IC expects based on its old discharge curve. The phone's power management IC interprets this voltage sag as a near-empty cell and cuts power to protect the system. One full slow-charge cycle, without fast charging enabled, resets the coulomb counter and lets the fuel gauge re-anchor its low-voltage threshold to the new cell. After that cycle, shutdowns at 20–30% typically stop.

Phone warm near the battery during the first few charges after replacement

A new lithium-polymer cell has higher internal impedance than a broken-in cell. During the first two to three charge cycles, the charge IC pushes current into that higher-impedance cell, and the energy lost to resistance becomes heat. This is normal and diminishes as the cell cycles. If the device stays warm past the third full charge, check that no fast-charge adapter is active — run the first cycles on a standard 5V/1A charger to limit current and reduce heat at the cell terminals.
