LIS1558ERPC Sony Ericsson Xperia Z3 Replacement Battery 3.8V 3100mAh

Sony Ericsson Xperia Z3 — 3.8V Li-Polymer Replacement Battery (LIS1558ERPC)

This is a 3.8V, 3100mAh lithium-polymer replacement cell for the Sony Ericsson Xperia Z3, Xperia Z3 Dual, Xperia Z3 LTE, D6653, and over a dozen related variants. It replaces OEM part number LIS1558ERPC directly. Dimensions are 79.05 × 60.26 × 4.26mm — confirm these against your original cell before fitting.

• Xperia Z3 variant compatibility: The Z3, Z3 Dual, and Z3 LTE all share the same battery footprint, connector pinout, and BMS handshake requirements. Each uses LIS1558ERPC because the charge IC expects the same voltage thresholds across the entire D6600-series platform.
• Bench tested on actual hardware: We ran this cell through the Z3's charge IC on the bench. The BMS accepted the new cell without error flags, charge current stepped through trickle, CC, and CV phases correctly, and the protection circuit tripped cleanly at the expected cutoff.
• Fuel gauge recalibration on first use: Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The fuel gauge IC is still calibrated to the old cell's discharge curve. Running one full slow cycle lets the coulomb counter build an accurate baseline before high-current charging applies.

Sudden shutdown at 20–30% after fitting a new cell

This happens because the Z3's fuel gauge IC carries forward calibration data from the old, degraded cell. When the modem fires at full power during a call or data burst, it pulls a current spike the new cell handles easily — but the fuel gauge misreads the resulting voltage dip as a near-empty state and triggers an emergency shutdown. The fix is one full discharge to 0% reported charge, then a full slow charge to 100% without interruption. After that cycle, the coulomb counter resets its endpoints against the actual new cell capacity.

Phone warm near the battery during the first charge after replacement

A new lithium-polymer cell has higher internal impedance than a broken-in cell. The charge IC compensates by maintaining the same target current, which generates more heat across the higher resistance — this is normal for the first one to three charge cycles. Monitor the temperature during the first charge; if the back of the phone becomes hot to the touch rather than warm, pause charging and let it cool before resuming. Internal impedance drops as the cell cycles, and heat during charging should return to normal levels by the third cycle. If warmth persists beyond that, check that the charge IC is not stuck at a higher-than-expected rate — the Z3 should charge at 1.5A maximum under standard conditions.
