Oppo Find X BLP675 Replacement Battery 7.7V 1600mAh

Oppo Find X Automobili Lamborghini Edition — 7.7V Li-Polymer Replacement Battery (BLP675)

This is a 7.7V, 1600mAh lithium-polymer replacement battery for the Oppo Find X Automobili Lamborghini Edition, CPH1875, CPH1871, and Find X Premium Edition smartphones. It carries OEM part number BLP675 and matches the original cell's voltage rail and connector specification. Swap it in when the original cell no longer holds adequate charge through a normal day.

• CPH1875 / CPH1871 platform fit: These model numbers share the same physical cell footprint, connector pinout, and BMS handshake protocol — all routed through the same charge IC. One replacement cell covers the full variant group without wiring or adapter changes.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the CPH1875 platform. The BMS accepted the cell handshake correctly, charge IC stepped through CC/CV phases without fault codes, and the fuel gauge IC tracked state-of-charge without spurious resets.
• First-cycle fast charge inhibit: On first use after installation, disable Oppo VOOC or SuperVOOC fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's actual discharge curve before high-current charging pushes into an uncalibrated state.

Sudden shutdown at 20–30% on the BLP675 replacement cell

This is a voltage cliff issue, not a capacity fault. Under modem, display, or simultaneous load, the new cell's voltage drops faster than the fuel gauge IC predicts — because its coulomb counter is still calibrated to the old, degraded cell curve. The phone sees voltage fall below the shutdown threshold before the percentage reading catches up. One full discharge down to automatic power-off, followed by a complete charge to 100%, resets the fuel gauge IC baseline. After that cycle, shutdowns at 20–30% typically stop.

VOOC fast charge not activating after cell replacement

Oppo's VOOC protocol requires a handshake between the charger, charge IC, and the battery's BMS before stepping up current. On the first cycle with a new cell, the BMS may reject the high-current handshake as a safety measure while it confirms cell impedance is within range. Charge the phone once on a standard 5V/2A USB charge — not a VOOC adapter — until it reaches 100%. On the next charge session, connect the VOOC adapter and the protocol handshake should complete normally at the expected voltage step.
