Sony Xperia XA Replacement Battery GB-S10-385871-010H 3.8V

Sony Xperia XA / F3116 — 3.8V Li-Polymer Replacement Battery (GB-S10-385871-010H)

This 3.8V, 2300mAh Li-Polymer cell replaces the original battery in the Sony Xperia XA, Xperia XA LTE, F3116, and F3115. It suits owners whose original cell can no longer sustain adequate charge capacity after years of cycling. Capacity figure is 8.74Wh at 3.8V nominal.

• Xperia XA / F3116 platform fit: The F3116, F3115, and Xperia XA LTE variants all draw from the same 3.8V power rail and use the same connector pinout and BMS handshake as the base Xperia XA. One cell covers the full range.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on an Xperia XA unit. The BMS accepted the cell without error flags, charge current ramped to CC phase normally, and the fuel gauge IC began tracking state-of-charge without intervention.
• Fuel gauge recalibration after cell swap: On first use after installation, disable fast charging and complete one full discharge-to-charge cycle before re-enabling it. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.

Sudden shutdown at 20–30% after fitting the replacement cell

The Xperia XA's fuel gauge IC retains the discharge curve of the old cell after a swap. When the new cell hits a voltage point the IC doesn't yet recognise as low, the phone interprets a normal load spike — modem transmission, screen wake — as a critical voltage drop and shuts down. The percentage shown at cutoff is meaningless until recalibration completes. Run two full discharge-charge cycles without fast charge enabled; by the third cycle the IC tracks the new curve accurately and shutdowns stop.

Phone warm near the battery during the first few charges

A new Li-Polymer cell has higher internal impedance than a well-cycled cell. The charge IC on the Xperia XA compensates by pushing slightly higher voltage during the CC phase, which generates more heat across the cell's internal resistance. This is normal for the first three to five cycles as impedance drops with conditioning. If the phone becomes hot to the touch — not just warm — or the charge IC throws an error in the battery stats menu, stop charging and check that the replacement cell's thickness (3.60mm) matches the bay clearance; pressure on the cell raises impedance and heat further.
