It fits model numbers F8131 and F8132, covering both single-SIM and dual-SIM variants. Dimensions are 71.80 × 53.80 × 4.80mm — match these against your original cell before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF8131 and F8132 coverage:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers the full X Performance lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge and charge sequence on an F8132 unit. The BMS accepted the handshake without fault codes, and the fuel gauge IC began tracking from the first cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% on the Xperia X Performance after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Xperia X Performance uses a coulomb counter-based fuel gauge IC that was calibrated to the original cell's discharge curve. A new cell has a different internal resistance profile, so the gauge can misread remaining capacity. Under modem load or screen-on bursts, the cell voltage drops faster than the IC expects, triggering an emergency shutdown well above 0%. One full discharge-charge cycle without fast charging corrects the calibration and eliminates premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone does not power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge in storage. If the voltage drops below approximately 2.5V per cell, the BMS enters a lockout state to prevent damage and blocks normal startup. The phone will show no response — no boot screen, no charge indicator. Connect the phone to a wall charger rated at least 5V\/1A and leave it for 20–30 minutes without interruption. Once the BMS detects voltage above its recovery threshold, the charge indicator will appear and the phone will respond normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392088146010,"sku":"BWCS-ERF813XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392088178778,"sku":"BWCS-ERF813XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392088211546,"sku":"BWCS-ERF813XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERF813XL-1.webp?v=1779143685","url":"https:\/\/batteryweb.com\/products\/sony-xperia-x-performance-replacement-battery-38v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
