It restores power capacity to devices showing rapid discharge, unexpected shutdowns, or complete power failure from cell wear. Voltage and connector match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e15 Pro compatibility — 24101PNB7C and 2410DPN6CC:\u003c\/strong\u003e\n    Both hardware revisions share the same battery bay dimensions, flex connector pinout, and BMS handshake protocol, so a single BM67 cell covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a 15 Pro unit. The BMS accepted the cell without error flags, charge current ramped correctly through CC\/CV stages, and the protection circuit tripped as expected at low-voltage cutoff.\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 and run one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before the coulomb counter begins tracking capacity against it.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 15 Pro reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Xiaomi 15 Pro uses a coulomb counter paired with a fuel gauge IC that learns the discharge curve of the installed cell over time. When you fit a new BM67, the IC still holds the old cell's curve in memory, so percentage readings are calculated against data that no longer matches the physical cell. This mismatch causes the display to show values that lag or jump, particularly in the 30–80% range. One complete slow discharge to shutdown followed by a full charge to 100% forces the IC to rebuild its reference curve against the new cell.\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 modem, display, or processor pulls a short current spike that the cell cannot sustain at its present state of charge — voltage drops below the BMS cutoff threshold of approximately 3.0V per cell and the circuit opens instantly. It is not a defective battery; it is the fuel gauge IC reporting a higher percentage than the cell can actually hold under load, because calibration has not yet completed. Run one full slow charge-discharge cycle and check whether shutdowns persist. If the phone still cuts out below 3.2V under load after two full cycles, verify the flex connector is fully seated at both ends.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391772459098,"sku":"BWCS-XMP151SL-1","price":38.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391772491866,"sku":"BWCS-XMP151SL-2","price":45.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391772524634,"sku":"BWCS-XMP151SL-3","price":49.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-XMP151SL-1.webp?v=1779141886","url":"https:\/\/batteryweb.com\/products\/xiaomi-15-pro-replacement-battery-385v-5950mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
