It restores power to the display, processor, modem, and all onboard functions. Capacity comes from the product data: 2150mAh \/ 16.64Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e8 Pro and V2141A compatibility:\u003c\/strong\u003e\n    Both model designations refer to the same physical hardware. The B-S0 cell shares the same connector pinout, BMS communication protocol, and voltage rail — no hardware modification needed to fit either variant.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the B-S0 replacement through a full charge and discharge cycle on the 8 Pro. The BMS handshake completed without fault codes, charge current stepped correctly through CC and CV phases, and the protection circuit tripped cleanly at low-voltage cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-Polymer cell has a slightly different discharge curve than the aged cell the fuel gauge IC was calibrated to. When voltage drops under modem or screen load, the IC reads a percentage that doesn't reflect actual remaining capacity. The phone shuts down to protect the cell even though the display shows charge remaining. One full discharge-to-cutoff cycle, followed by a complete charge without interruption, allows the coulomb counter to map the new cell's curve accurately and eliminates premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not accepted on first cycle after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge cycle after installation, some units revert to standard 5V charging rather than accepting the IQOO proprietary fast charge protocol. The charge IC is negotiating with a new BMS and defaults to the lowest safe rate until it confirms cell parameters. Completing one standard charge cycle resolves the handshake. If fast charging still does not engage after that, check that the original IQOO charger and cable are in use — third-party cables with high resistance can prevent protocol negotiation above 9V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391858868314,"sku":"BWCS-BKQ810SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391858901082,"sku":"BWCS-BKQ810SL-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391858933850,"sku":"BWCS-BKQ810SL-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKQ810SL-1.webp?v=1779142367","url":"https:\/\/batteryweb.com\/products\/iqoo-8-pro-replacement-battery-774v-2150mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
