It fits the Vivo X60 Pro Plus, X60 Pro+, X60 Pro+ 5G, and V2056A. It replaces a degraded or failed original cell in this Android flagship smartphone.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX60 Pro+ platform compatibility:\u003c\/strong\u003e\n    The X60 Pro Plus, X60 Pro+ 5G, and V2056A share the same battery bay dimensions, connector pinout, and BMS handshake protocol. All variants draw from the same 3.87V nominal rail, so one cell covers the entire line without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on the X60 Pro+ platform and confirmed the BMS accepted the charge IC handshake on first contact. The protection circuit tripped correctly at the low-voltage cutoff and reset cleanly on reconnect.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still mapped to the old cell's discharge curve. The new cell has a steeper voltage cliff at lower states of charge, so the phone hits the BMS undervoltage cutoff while the OS still shows charge remaining. The fix is one full uninterrupted discharge to automatic shutdown, followed by a full charge without interruption. After that cycle, the coulomb counter resets its endpoint reference to match the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD or proprietary fast charge not working on the first cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new high-impedance cell can cause the charge IC to fall back to standard 5V charging on the first session — this is a protective handshake response, not a fault with the battery. The charge controller measures internal resistance and limits current if the cell reads outside expected parameters. Run one standard slow charge to completion first. On the second cycle, fast charging protocols negotiate normally once the cell's impedance drops into the expected range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391833079898,"sku":"BWCS-BKX610SL-1","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391833112666,"sku":"BWCS-BKX610SL-2","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391833145434,"sku":"BWCS-BKX610SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKX610SL-1.webp?v=1779142264","url":"https:\/\/batteryweb.com\/products\/vivo-x60-pro-plus-replacement-battery-387v-4100mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
