It uses OEM part number B-96 and fits the internal battery bay directly. Capacity is rated at 15.4Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX6 Plus A platform fit:\u003c\/strong\u003e\n    Both listed models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — 85.05 x 68.10 x 4.40 mm cell with a matching NTC thermistor line the charge IC uses to regulate current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the X6 Plus A platform, confirmed the BMS accepted the cell without triggering a fault code, and verified the charge IC handed off to trickle mode correctly at top-of-charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    On first use, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging begins on 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\"\u003eWhy the X6 Plus A reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the X6 Plus A stores a discharge curve from the original cell. When you install a new cell, that stored curve no longer matches the new cell's actual voltage-to-capacity relationship. The result is percentage readings that jump, stall, or drop suddenly — especially below 30%. One full slow-charge cycle forces the coulomb counter to re-anchor its reference points against the new cell, correcting the readout.\u003c\/p\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\"\u003eThis happens when the cell voltage drops sharply under a high-draw load — modem transmission bursts or display brightness spikes — before the fuel gauge has recalibrated. The phone reads 25% but the cell voltage has already crossed the BMS cutoff threshold, typically around 3.0V under load. The BMS shuts the device down to protect the cell. Run one full uncalibrated cycle first, then verify the issue clears; if shutdown persists, confirm resting voltage reads above 3.7V after a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392111312986,"sku":"BWCS-BYX620SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392111345754,"sku":"BWCS-BYX620SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392111378522,"sku":"BWCS-BYX620SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BYX620SL-1.webp?v=1779143847","url":"https:\/\/batteryweb.com\/products\/vivo-x6-plus-a-replacement-battery-385v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
