About this replacement
Oppo Realme GT Neo 2 / GT Pro 2 — 7.74V Li-Polymer Replacement Battery (BLP887)
This is a 7.74V, 2150mAh (16.64Wh) Li-Polymer cell for the Realme GT Neo 2 and Realme GT Pro 2 smartphones. It replaces OEM part BLP887 when the original cell degrades, drops capacity, or causes unexpected shutdowns. It matches the original connector, dimensions (91.40 × 63.70 × 4.65mm), and BMS handshake requirements for both models.
- GT Neo 2 and GT Pro 2 shared platform: Both devices run the same power rail voltage and use an identical flex connector pinout, which is why they share the BLP887 cell. The BMS on each device negotiates the same charge cutoff at 8.72V and discharge floor at 6.0V — no firmware difference affects cell compatibility between the two models.
- Bench tested on actual hardware: We cycled this cell on a GT Neo 2 unit and confirmed BMS handshake on first insertion, stable charge acceptance through three full cycles, and no thermal flag during SuperDart charge activation after the initial calibration cycle.
- Fuel gauge recalibration on first use: After installation, disable fast charging and run one complete discharge-to-charge cycle at standard speed. The fuel gauge IC on these devices calibrates its coulomb counter against the new cell's discharge curve — skipping this step can cause the percentage to jump or trigger premature low-battery cutoffs until the IC self-corrects.
Sudden shutdown at 20–30% on the Realme GT Neo 2
An aged BLP887 cell develops elevated internal resistance. Under the combined load of the Snapdragon 870's modem and a high-refresh display, the cell voltage sags sharply — dropping below the BMS cutoff threshold even though the fuel gauge still shows charge remaining. The BMS reads a genuine undervoltage condition and shuts the device down to protect the cell. After fitting a new cell, confirm the resting open-circuit voltage reads above 3.87V per cell (7.74V at the pack terminals) before powering on.
SuperDart fast charge not activating after cell replacement
Realme's SuperDart protocol requires the charge IC to authenticate with the battery BMS before stepping up current. On a fresh cell with an uncalibrated coulomb counter, the charge IC sometimes defaults to standard 5W input on the first cycle as a precaution. This is not a fault with the charger or cable. Run one full standard-speed charge cycle first — SuperDart handshake typically activates from the second charge onward once the BMS has logged a complete charge signature.
