It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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.

Frequently Asked Questions

My Moto Edge Plus shuts off at around 25% — did I install the battery wrong?

The install is almost certainly fine. What you're seeing is the fuel gauge IC still calibrated to the old cell's discharge curve — it reports 25% remaining while the actual cell voltage has dropped below the BMS cutoff under modem or display load. Run the phone down until it shuts itself off, then charge it to 100% in one uninterrupted session with fast charging disabled. After that full cycle, the coulomb counter resets its endpoints to match the new cell and the early shutdowns stop.

The percentage on my Edge Plus keeps jumping around after I put in the new battery — is the cell faulty?

It's not a faulty cell. The fuel gauge IC is recalibrating against the new cell's impedance and discharge characteristics, which differ from the old degraded cell it was trained on. Erratic percentage readings — jumps of 5–15% in either direction — are normal during the first one to two charge cycles. Complete two full discharge-to-shutdown and charge-to-100% cycles with fast charging off, and the readings will stabilise as the coulomb counter builds an accurate state-of-charge map.

The phone gets noticeably warm near the battery during the first charge after replacement — is that normal?

Yes, and here's why. A new Li-Polymer cell has higher internal impedance than a cell that has been cycled hundreds of times. The charge IC pushes current into that higher resistance, and some of that energy dissipates as heat rather than stored charge. The warmth is most pronounced on the first one or two charges and drops off as the cell's impedance settles. If the phone stays hot throughout a full charge on the third cycle or beyond, check that the charge IC isn't stuck in a fast-charge handshake loop — toggle Airplane Mode off and back on to force a modem power state reset.
