It fits the same physical slot and uses the same connector as the original LIS1632ERPC cell. When the factory battery can no longer hold charge through a full day, this cell restores that capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXperia XZ and XZ Dual SIM compatibility:\u003c\/strong\u003e\n    The F8331 (single SIM) and F8332 (Dual SIM) share an identical battery bay, connector pinout, and BMS handshake profile. Both accept this cell without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an F8332 unit. The BMS accepted charge without fault codes, and the protection circuit tripped correctly at low-voltage cutoff as expected.\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 into an uncalibrated cell state.\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 XZ after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. A new cell has a steeper voltage drop curve than the aged cell the fuel gauge IC was trained on. Under modem or screen load, voltage sags below the shutdown threshold faster than the gauge predicts. The phone cuts out even though the displayed percentage still reads above zero. One full discharge-charge cycle with fast charging off forces the coulomb counter to re-map the new cell curve and eliminates most false shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not activating on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSony's Quick Charge handshake on the XZ requires the BMS to report a valid cell state before the charge IC negotiates high-current delivery. On a brand-new cell at a low state of charge, the BMS can flag an uncalibrated status and the charger falls back to standard 5V\/0.9A input. This is not a fault with the cell or the charger. Charge the phone fully once on a standard charger, then allow a complete discharge to around 5%, and fast charging will engage normally on the following cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392081231962,"sku":"BWCS-ERF833XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392081264730,"sku":"BWCS-ERF833XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392081297498,"sku":"BWCS-ERF833XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERF833XL-1.webp?v=1779143621","url":"https:\/\/batteryweb.com\/products\/sony-xperia-xz-replacement-battery-38v-2850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
