About this replacement
Wiko Getaway — 3.8V Li-Polymer 2000mAh Replacement Battery (TLE14J14)
This is a 3.8V Li-Polymer, 2000mAh replacement battery for the Wiko Getaway smartphone. It fits the compact Android Getaway handset and matches the original cell's voltage and physical footprint. OEM part numbers TLE14J14 and TLE14I14 both apply to this battery.
- Getaway platform fit: The Getaway uses a dedicated connector and contact layout tied to this cell size. The BMS reads cell impedance on first boot — the replacement cell must sit within the voltage window the phone's charge IC expects, which this unit does.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the bench, confirming the BMS accepted the cell without flagging over-voltage or under-voltage faults, and that the charge IC completed a full cycle without thermal cutoff.
- First-cycle fuel gauge reset: On first use after installation, disable fast charging and let the phone run through one complete discharge-to-charge cycle. This gives the fuel gauge IC time to recalibrate its discharge curve against the new cell before high-current charging begins on an uncalibrated register.
Why the Getaway reports wrong battery percentage after a cell swap
The Getaway uses a fuel gauge IC that stores a learned discharge curve from the original cell. When you install a new cell, the IC still references that old curve, so the percentage readout drifts — sometimes showing 50% when the phone is closer to 20%. One full discharge-charge cycle lets the coulomb counter reset its baseline against the new cell's actual capacity. Until that cycle completes, percentage readings will be approximate. After calibration, the gauge should track to within a few percent of actual state of charge.
Sudden shutdown at 20–30% on the replacement cell
This happens when the cell cannot hold voltage under the combined load of the modem radio, screen, and background processes — even though the fuel gauge still shows charge remaining. The voltage drops sharply below the BMS cutoff threshold, and the phone shuts down before the gauge catches up. It is more common in the first few cycles before the fuel gauge IC has fully recalibrated. Run two complete discharge-charge cycles and check whether the shutdown point moves; if the phone stays on past 15%, the gauge is converging. If shutdowns continue below 3.6V under load, check that the replacement cell contacts are seated flush against the board connector.
