Wiko C210AEBATT Replacement Battery 3.8V 2300mAh

Wiko C210 / Life — 3.8V Li-ion Replacement Battery (C210AEBATT)

This is a 3.8V, 2300mAh Li-ion cell that replaces the original C210AEBATT battery in the Wiko C210 and Wiko Life smartphones. It restores full charging and discharge operation when the original cell has degraded or failed to hold voltage. Dimensions are 77.00 × 59.90 × 4.10mm — confirm clearance before ordering if the back cover has been replaced.

• C210 and Life compatibility: Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol, which is why a single cell covers both. Voltage rail and thermistor line are identical across the two SKUs.
• Bench tested on actual hardware: We cycled this cell through charge and load on the C210 platform. The BMS accepted the charge IC handshake on the first connect, and protection thresholds — overvoltage at 4.2V, undervoltage cutoff at 2.5V — triggered correctly under test load.
• First-cycle calibration on the C210: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes into an uncalibrated cell.

Sudden shutdown at 20–30% on a replacement cell in the C210

This is a voltage cliff, not a capacity fault. Under modem transmission bursts or screen-on load, the new cell momentarily drops below the threshold the OS reads as safe, and the phone cuts out even though the coulomb counter still shows charge remaining. The fuel gauge IC was calibrated to the old cell's internal resistance curve, so it misreads headroom on the new cell. Run one full discharge to below 5% and a full uninterrupted charge cycle — this resets the coulomb counter baseline and the shutdowns typically stop.

A new cell arrives with higher internal impedance than a broken-in cell. The charge IC compensates by adjusting current, and that adjustment produces more heat at the cell surface during CC phase. This is expected on cycles one through three and settles as the cell's impedance drops with use. If the phone remains hot after five full cycles, check that no app is holding a wake lock during charging — that adds CPU heat on top of charge IC heat and compounds the symptom. Normal skin temperature during charging should fall below 38°C by cycle five.
