About this replacement
Samsung Galaxy Xcover Pro — 3.85V Li-Polymer Replacement Battery (EB-BG715BBE)
This is a 3200mAh Li-Polymer cell at 3.85V nominal, replacing part number EB-BG715BBE in the Samsung Galaxy Xcover Pro. It fits the SM-G715, SM-G715FN/DS, and SM-G715U variants. The Xcover Pro is a rugged smartphone — drop-rated, PTT-capable — and this battery matches the original cell's dimensions and BMS handshake exactly.
- SM-G715 variant compatibility: The SM-G715, SM-G715FN/DS, and SM-G715U all share the same 3.85V power rail, connector pinout, and fuel gauge IC communication protocol. One cell fits all three without modification.
- Bench tested on actual hardware: We ran this cell in an SM-G715FN/DS under a mixed modem-plus-screen load. The BMS held stable voltage above 3.6V through the mid-discharge range and executed clean low-voltage cutoff at the expected floor — no false trips on the PTT radio burst draw.
- 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 its coulomb counter against the new cell's actual discharge curve before high-current charging pushes current into an uncalibrated reference baseline.
Sudden shutdown at 20–30% on the Xcover Pro after a cell swap
The Xcover Pro's modem and display draw a combined spike that exceeds what a degraded — or freshly installed, uncalibrated — cell can sustain at low state-of-charge. The fuel gauge IC still reports 20–30% remaining, but the cell's actual voltage drops below the shutdown threshold under that load. This is a voltage cliff, not a capacity failure. One full discharge-charge cycle recalibrates the coulomb counter and eliminates the premature cutoff on most units.
USB-PD fast charge rejected on first cycle after replacement
Samsung's Adaptive Fast Charging handshake runs between the charge IC and the BMS on the new cell. On the first cycle, the BMS defaults to a conservative current limit until it completes an initial calibration pass — the phone may show "Charging" rather than "Fast Charging." This is normal behaviour, not a fault with the cell or cable. Plug in with the original Samsung charger, let the first full charge complete without interruption, and fast charging will re-enable on the second cycle.
