About this replacement
Motorola Moto G Power 5G XT2311 (2023) — 3.89V Li-Polymer Replacement Battery (PD50)
This is a 3.89V, 4850mAh (18.87Wh) Li-Polymer replacement battery for the Motorola Moto G Power 5G (XT2311, 2023). It replaces OEM part numbers PD50 and LW476486. The cell is sized to the original 87.00 x 63.90 x 4.60mm footprint.
- XT2311 fit notes: The 2023 Moto G Power 5G uses a specific connector pinout and BMS handshake tied to the PD50 cell family. Substituting a cell from another G Power generation — even one with similar capacity — will cause the charge IC to reject the pack or report a fault state.
- Bench tested on actual hardware: We ran this cell on an XT2311 board. The BMS accepted the pack on first connect, charge IC entered CC/CV mode correctly, and the fuel gauge IC began coulomb counting from the first discharge cycle without throwing a fault flag.
- Fuel gauge recalibration after install: On first use after installation, disable fast charging and complete one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before fast charging pushes high current into an uncalibrated pack.
Why the Moto G Power 5G reports wrong battery percentage after a cell swap
The XT2311 uses a coulomb-counter-based fuel gauge IC that holds the old cell's discharge curve in memory. After you swap the cell, that stored curve no longer matches the new cell's actual voltage-to-capacity relationship. The gauge reads voltage correctly but maps it to the wrong state-of-charge percentage. One full slow-rate discharge to 0% followed by an uninterrupted charge to 100% forces the IC to rewrite its reference curve against the new cell.
Sudden shutdown at 20–30% on the new cell
This is a voltage cliff event, not a capacity problem. Under modem or display load, the new cell's voltage drops faster than the fuel gauge IC expects — the board reads the voltage dip as a critically low-battery condition and shuts down to protect the SoC. It typically resolves after the fuel gauge IC has completed one full calibration cycle. If shutdowns persist past two full cycles, check that the cell voltage at shutdown is not dropping below 3.4V — that would indicate a weak cell rather than a calibration lag.
