Coolpad 7295 Replacement Battery CPLD-19 3.7V 1750mAh

Coolpad 7295 / 5930 / 8720 — 3.7V Li-ion Replacement Battery (CPLD-19)

This is a 3.7V, 1750mAh Li-ion cell that replaces the original battery in the Coolpad 7295, 5930, 8720, and 8295. It fits phones sharing the CPLD-19 platform, and also carries part numbers CPLD-115 and CPLD-116. Dimensions are 70.77 × 53.11 × 4.34mm — confirm these against your original before installing.

• Multi-model fit — why these phones share one cell: The 7295, 5930, 8720, and 8295 run the same 3.7V power rail and use a common connector pinout. Coolpad carried the same cell form factor across these variants, which is why one part number covers the group. The BMS handshake protocol is identical across all listed models.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the 7295 platform. The BMS accepted charge from a standard 5V USB source without fault flags. Cutoff voltage on discharge held at the expected low-end threshold before the device shut down cleanly.
• Fuel gauge recalibration on first use: After installation, disable fast charging if your variant supports it. Run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC a clean discharge curve to map against the new cell before it starts making percentage estimates.

Why the Coolpad 7295 reports wrong battery percentage after a cell swap

The fuel gauge IC on the 7295 stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The IC reads voltage and maps it against the old curve, producing percentage estimates that are off — sometimes by 15–20 points. One complete discharge-charge cycle forces the coulomb counter to reset its reference and begin tracking the new cell from scratch. Until that cycle runs, percentage jumps and early shutdowns are expected behaviour, not a fault with the replacement cell.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff, not a calibration issue. Under modem load or display brightness spikes, the cell voltage drops faster than the fuel gauge IC expects, and the phone hits the hardware undervoltage cutoff before the percentage readout catches up. It typically appears in the first few cycles on a fresh cell. After one full calibration cycle, the IC tracks the voltage curve more accurately and the early shutdowns stop. If shutdown persists below 3.5V after three full cycles, check that the connector is fully seated — a partial connection increases resistance and accelerates voltage sag under load.
