Motorola EY30 Moto X Play XT1092 Replacement Battery 3.8V 2000mAh

Motorola Moto X Play XT1092 — 3.8V Li-Polymer Replacement Battery (EY30 / SNN5945A)

This is a 3.8V, 2000mAh Li-Polymer replacement battery for the Motorola Moto X Play. It fits the XT1092, XT1096, XT1097, and Moto X 3605 variants. Swap it in when the original cell can no longer hold a usable charge through a normal day of use.

• XT1092 / XT1096 / XT1097 platform fit: These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The EY30 cell format — 90.92 × 58.98 × 2.70mm — seats correctly across all listed variants without modification to the connector or adhesive strip.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Moto X Play unit. The BMS negotiated charge termination at 4.35V and triggered low-voltage cutoff at 3.0V. No mid-cycle dropouts or charge IC faults were logged during three full cycles.
• Fuel gauge recalibration after install: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging pushes amperage into an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on the Moto X Play after a cell swap

This is a voltage-cliff failure. The fuel gauge IC still references the discharge curve of the old, degraded cell, so it misreads remaining capacity on the new cell. When the modem fires during a call or the screen peaks in brightness, current draw spikes and cell voltage drops faster than the gauge predicts. The phone interprets this as an emergency cutoff condition and shuts down, even though actual capacity remains. One full discharge-to-cutoff and slow recharge cycle forces the coulomb counter to recalibrate against the new cell, and false shutdowns typically stop after that cycle.

Phone warm near the battery during the first charge after replacement

A new Li-Polymer cell has higher internal impedance than a broken-in one. During the first charge cycle, the charge IC pushes current into a cell that hasn't yet settled to its operating impedance, and that resistance converts some of that energy to heat. This is normal and should taper off after the first or second full cycle as impedance drops. If the phone feels hot — not just warm — above the battery area after the second full cycle, check that the replacement cell is seated flat and the back cover is not compressing the cell. Warmth above 40°C on the outer case after cycle two warrants a closer look at seating.
