It fits directly into the Pixel 3 XL chassis and reconnects to the stock charge IC and fuel gauge. Use this when the original cell has degraded, swells, or can no longer hold a usable charge level.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePixel 3 XL compatibility:\u003c\/strong\u003e\n    The Pixel 3 XL uses a dedicated battery bay sized for the G013C-B cell — 77.45 x 54.04 x 4.65mm. The connector pinout carries both power and the BMS data line that talks directly to the Qualcomm PM845 PMIC. A cell outside these specs will not seat correctly or communicate with the charge controller.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a Pixel 3 XL board and confirmed the BMS handshake completed on first boot, fast charge negotiation triggered via USB-PD on the second full cycle, and the coulomb counter began tracking state of charge without error flags in the battery stats log.\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. The fuel gauge IC on the Pixel 3 XL calibrates its discharge curve against the cell it sees — running a slow cycle first lets it map the new cell's voltage profile before high-current USB-PD charging begins pushing current into an uncalibrated curve.\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 Pixel 3 XL after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the Pixel 3 XL's fuel gauge IC still holds the discharge curve from the old, degraded cell. When the new cell hits a voltage point the IC doesn't expect — typically around 3.65–3.70V under modem or screen load — the PMIC reads it as a critical low and cuts power immediately. The phone shuts down even though real capacity remains. One full slow discharge-charge cycle lets the coulomb counter relearn the new cell's voltage-to-capacity relationship and eliminates the false cutoff.\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\"\u003eAfter a cell swap, the Pixel 3 XL charge IC defaults to a lower current rate until it confirms BMS communication is stable. On the first cycle, the handshake between the new cell's BMS and the PM845 PMIC can take a full charge-discharge pass to complete authentication. Fast charge via USB-PD may appear absent — the phone charges slowly and the fast charge indicator does not appear in the status bar. Complete one full cycle on a standard 5W charge, then reconnect the USB-PD adapter — fast charge should negotiate correctly from 3.85V upward on the second cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392016154714,"sku":"BWCS-GPW300SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392016187482,"sku":"BWCS-GPW300SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392016220250,"sku":"BWCS-GPW300SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GPW300SL-1.webp?v=1779142904","url":"https:\/\/batteryweb.com\/products\/google-pixel-xl-3-replacement-battery-385v-3000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
