About this replacement
Motorola Moto Edge Plus XT2061 Series — 3.87V Li-Polymer Replacement Battery (LW50)
This 3800mAh Li-Polymer cell replaces the LW50 battery in the Motorola Moto Edge Plus and Moto Edge+ (XT2061-1, XT2061-3). It runs at 3.87V nominal with a 14.71Wh total energy rating. If your Edge Plus is shutting down unexpectedly or no longer holding a charge, this is the direct cell swap.
- XT2061-1 and XT2061-3 fitment: Both variants use the same battery bay dimensions, connector pinout, and BMS handshake protocol. The LW50 cell fits either board revision without modification — the fuel gauge IC communicates over the same two-wire interface on both.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an XT2061 board. The BMS accepted charge current without fault flags, and the coulomb counter tracked state-of-charge correctly after one full calibration cycle.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging is applied to an uncalibrated cell.
Sudden shutdown at 20–30% on the replacement cell
The Edge Plus modem and display draw heavy current spikes, especially during 5G handoffs or screen-on wake events. A fresh cell with an uncalibrated fuel gauge IC can report 25% state-of-charge while the actual cell voltage has already sagged below the BMS cutoff threshold under that load. The BMS trips the protection circuit and the phone cuts power instantly — not a software crash. Run one full drain-to-shutdown followed by an uninterrupted charge to 100% to anchor the coulomb counter to the new cell's actual capacity endpoints.
USB-PD fast charge not engaging after installation
The Edge Plus uses Motorola's TurboPower protocol, which requires a handshake between the charge IC and the battery BMS before high-voltage fast charging activates. On the first cycle after a cell swap, the charge IC may default to standard 5V/0.9A charging while it verifies BMS state. This is expected behaviour — not a fault with the charger or the cable. Complete one full standard charge cycle first; TurboPower handshake typically resumes on the second charge session once the BMS registers a valid charge history.
