BL-N3150 GIONEE Elife S6 Replacement Battery 3.85V 3050mAh

GIONEE Elife S6 / GN9010 Series — 3.85V Li-Polymer Replacement Battery (BL-N3150)

This is a 3050mAh, 3.85V lithium-polymer replacement battery for the GIONEE Elife S6, GN9010, GN9010L, and GN9010L Dual SIM. It uses OEM part number BL-N3150 and fits the same footprint at 84.90 × 63.05 × 3.75mm. If your original cell is swelling, dropping charge quickly, or refusing to hold a usable state of charge, this is the direct swap.

• GN9010 and GN9010L platform fit: The GN9010 and GN9010L share the same battery bay dimensions, connector pinout, and BMS handshake protocol — both accept the BL-N3150 without modification. Voltage rail and NTC thermistor placement are identical across the variant lineup.
• Bench tested on actual hardware: We ran this cell on a GN9010L and monitored BMS communication across charge and discharge cycles. The protection IC responded correctly at both undervoltage cutoff and full-charge termination, with no false trips under screen-on modem load.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one full discharge to near-shutdown, then charge to 100% uninterrupted. This gives the coulomb counter a clean reference cycle against the new cell's actual discharge curve before high-current charging begins.

Why the Elife S6 reports wrong battery percentage after a cell swap

The Elife S6 uses a fuel gauge IC that tracks charge state by measuring cumulative current in and out — a process called coulomb counting. When you replace the cell, the IC still holds the discharge curve profile from the old, degraded battery. It maps voltage readings to percentage using stale data, so 60% on screen might be 45% actual charge. One complete uninterrupted discharge-charge cycle overwrites the old reference data and lets the IC build an accurate model of the new cell's voltage-to-capacity relationship.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops below a sustainable threshold under high instantaneous load — typically when the modem transmits or the display is at full brightness. The BL-N3150 cell voltage collapses faster than the fuel gauge IC predicts at that state of charge, triggering a hard shutdown before the percentage reaches zero. It is more common in the first few cycles before the fuel gauge recalibrates. Run two full discharge-charge cycles without fast charging; if shutdowns persist past that point, check that the battery connector is fully seated and the NTC pad has contact — a floating thermistor can cause premature BMS cutoff.
