It fits where the stock cell sits — same footprint at 82.70 x 63.60 x 5.50mm. Replace it when the original cell no longer holds charge or shuts down unexpectedly under load.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXiaomi 13 Pro platform fit:\u003c\/strong\u003e\n    The 2210132C and 2210132G share the same battery bay geometry, flex connector pinout, and BMS handshake protocol — one 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 13 Pro unit, confirmed BMS communication was accepted, and verified the charge IC reached full termination voltage without tripping overcurrent protection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\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 fast 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 BP4D cell has a discharge curve the phone's coulomb counter has never seen before. Under heavy modem or display load, the phone pulls current the fuel gauge IC cannot predict accurately, and the cell voltage drops below the BMS cutoff threshold before the percentage reads zero. The phone reads 25% but the actual cell voltage has already crossed 3.4V under load — shutdown triggers. One full discharge-charge cycle without fast charging resets the coulomb counter baseline and the shutdowns stop.\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\"\u003eXiaomi's HyperCharge protocol requires the BMS to handshake with the charge IC before high-rate charging is permitted. On a brand-new cell, the BMS may present a high impedance state that causes the charge IC to fall back to standard 5V USB charging as a precaution. This is not a fault — it resolves after the first full charge cycle when the BMS registers the cell as initialised. If fast charge still does not activate after the second full cycle, check that the original Xiaomi charger and cable are in use, as third-party accessories often cannot complete the HyperCharge handshake regardless of cell condition.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391818629210,"sku":"BWCS-MUM420SL-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391818661978,"sku":"BWCS-MUM420SL-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391818694746,"sku":"BWCS-MUM420SL-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MUM420SL-1.webp?v=1779142265","url":"https:\/\/batteryweb.com\/products\/xiaomi-13-pro-replacement-battery-389v-4700mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
