TLP15016 Wiko Highway Star Replacement Battery 3.8V 2300mAh

Wiko Highway Star / Highway Star 4G — 3.8V Li-Polymer Replacement Battery (TLP15016)

This 3.8V, 2300mAh (8.74Wh) lithium-polymer cell replaces the original TLP15016 battery in the Wiko Highway Star, Highway Star 4G, and Highway Star 4G Dual SIM. It also cross-references OEM part numbers S104-Q14000-001 and S104-Q06000-000. If your Highway Star struggles to hold charge or shuts down unexpectedly, this is the direct swap.

• Highway Star series compatibility: The standard, 4G, and 4G Dual SIM variants share the same battery footprint — 112.10 x 41.70 x 3.20mm — and the same connector pinout. The BMS handshake protocol is identical across all three, so one cell covers the full lineup without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Highway Star platform and monitored the BMS cutoff thresholds. The protection circuit responded correctly at both the low-voltage floor and the high-voltage ceiling, with no anomalous cutoffs mid-cycle.
• Fuel gauge recalibration after installation: On first use after fitting, disable fast charging and run one complete discharge-to-charge cycle. The fuel gauge IC on the Highway Star calibrates its coulomb counter against the new cell's discharge curve during this first pass — skipping it leads to inaccurate percentage readings for the first several cycles.

Sudden shutdown at 20–30% on the Highway Star after a cell swap

This is a voltage cliff issue, not a capacity fault. The new cell's discharge curve doesn't match the profile the fuel gauge IC learned from the degraded original — so the OS reads 25% while the actual cell voltage has already dropped below the modem's minimum operating rail. Under screen-on or active data load, voltage sags further and the phone cuts out. Run one full discharge down to auto-shutdown, then charge uninterrupted to 100% — this resets the coulomb counter and tightens percentage accuracy against the new cell.

Phone won't power on after the replacement battery sat in storage

Li-polymer cells self-discharge in storage. If the TLP15016 arrived below roughly 2.5V per cell, the BMS may have tripped into lockout mode to prevent damage — and the phone will show nothing when you press power. Connect the phone to a wall charger, not a PC port, and leave it for 15–20 minutes without pressing anything. The charge IC needs to trickle current into the cell to lift voltage above the BMS re-enable threshold before the phone will respond. Once the charging indicator appears, continue to a full charge before first use.
