LIS1593ERPC Sony Xperia Z5 Replacement Battery 3.8V 2800mAh

Sony Xperia Z5 / Z5 Dual — 3.8V Li-Polymer Replacement Battery (LIS1593ERPC)

This is a 3.8V, 2800mAh Li-Polymer cell replacing the internal battery in the Sony Xperia Z5 and Z5 Dual. It fits both single and dual-SIM variants, including the SO-01H and SOV32 carrier models. Swap it when the original cell no longer holds adequate charge or the phone shuts down unexpectedly under load.

• Z5 and Z5 Dual compatibility: Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The LIS1593ERPC fits all regional models in this family — voltage rails, thermistor line, and NTC resistance are identical across SO-01H, SOV32, and unlocked units.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Z5 unit. The BMS accepted the cell without error flags, thermal reporting stayed within normal bounds, and the charge IC recognised the cell correctly from first insertion.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% on the Xperia Z5 after a cell swap

The Xperia Z5's fuel gauge IC stores a learned discharge curve from the original cell. After a swap, that stored curve no longer matches the new cell's voltage-versus-capacity profile. When the modem fires at full power or the display peaks, the new cell's voltage drops faster than the IC predicts — it reads this as a sudden voltage cliff and triggers an emergency shutdown. One complete discharge cycle, draining to automatic shutdown and charging to 100% without interruption, forces the coulomb counter to re-anchor to the actual cell. After that cycle, the reported percentage and real capacity align correctly.

Phone warm near the battery during the first charge after replacement

A freshly installed cell typically arrives with higher internal impedance than a broken-in cell. The charge IC on the Z5 pushes current at a fixed rate regardless, so more energy converts to heat across that impedance during early cycles. This is normal and reduces after two or three charge cycles as the cell's internal resistance drops. If warmth persists beyond three cycles or the phone becomes hot to the touch, check that the battery connector is fully seated — a partially connected thermistor line prevents the charge IC from reading cell temperature correctly.
