Sony Xperia Z4 Tablet Compatible Battery LIS2210ERPC 3.8V 6000mAh

Sony Xperia Z4 Tablet SGP712 / SGP771 — 3.8V Li-Polymer Replacement Battery (LIS2210ERPC)

This 3.8V, 6000mAh lithium-polymer battery replaces the original LIS2210ERPC / LIS2210ERPX cell in the Sony Xperia Z4 Tablet. It fits the SGP712, SGP771, and SO-05G variants. Swap it in when the original cell can no longer hold enough charge to get through a normal day of media and productivity use.

• SGP712 and SGP771 platform fit: Both tablet variants share the same chassis dimensions, connector pinout, and charge IC handshake. The LIS2210ERPC footprint — 219.35 x 91.72 x 2.30mm — fits both without modification to the flex cable or adhesive frame.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the SGP712 board and monitored BMS communication with the charge IC. The protection circuit responded correctly to overvoltage and over-discharge thresholds with no false cutoffs.
• Fuel gauge reset after installation: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100%. This forces the fuel gauge IC to recalibrate its capacity map against the new cell and clears the inaccurate percentage readings that commonly appear after a swap.

Xperia Z4 Tablet shutting down at 15–25% remaining

This happens because the Snapdragon 810 SoC, display, and active WiFi draw current simultaneously during typical use, which collapses the cell voltage faster than the fuel gauge predicts. The gauge was calibrated to the old degraded cell, so its remaining-capacity model is wrong for a new 6000mAh cell. After a full discharge-to-shutoff and one uninterrupted charge to 100%, the SOC controller rewrites its discharge curve. Shutdowns that were occurring at 20% typically stop once the gauge has one complete reference cycle.

Fast charging not resuming after battery replacement

The Xperia Z4 Tablet uses a proprietary charge negotiation step between the charge IC and the battery's BMS before allowing higher current. On the first charge with a new cell, the IC runs a verification handshake that caps current until the cycle completes. Plug into the original Sony charger or a USB-PD adapter rated at 5V/2A or higher and let the first charge run to 100% without interruption. Fast charge availability is typically restored from the second cycle onward.
