It replaces an original cell that has degraded through repeated charge cycles or lost the ability to hold a charge. Voltage and physical dimensions — 87.40 x 64.30 x 5.00mm — match the OEM specification directly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMi 10T Lite 5G and Mi 10i 5G compatibility:\u003c\/strong\u003e\n    Both the M2007J17G and M2007J17I share the same battery bay geometry, connector pinout, and BMS handshake protocol — that is why a single BM4W cell covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the Mi 10T Lite 5G and confirmed the BMS accepted the cell, reported capacity correctly after one calibration cycle, and did not trigger thermal cutoff under sustained 5G modem load.\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 complete discharge-charge cycle at standard current. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before high-current charging pushes load 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 Mi 10T Lite 5G\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. When the 5G modem, display, and processor draw current simultaneously, a degraded or freshly installed uncalibrated cell can drop below the BMS cutoff voltage under load — even though the fuel gauge still reads 20–30%. The phone shuts down to protect the cell. One full discharge-charge calibration cycle resolves this on a new BM4W by anchoring the fuel gauge IC to the actual discharge curve of the new cell. After calibration, the reported percentage tracks real cell voltage accurately down to the 3.0V lower threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone will not power on after the BM4W sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-polymer cells shipped or stored for extended periods can fall below 2.5V per cell, which triggers a BMS lockout to prevent further discharge damage. The Mi 10T Lite 5G will show no response — no charging animation, no vibration. Connect the phone to a 5V\/2A charger and leave it undisturbed for 15–30 minutes; the BMS uses a trickle-charge recovery path to bring the cell back above the lockout threshold before allowing normal charging to resume. If the screen still shows nothing after 30 minutes, disconnect and reconnect the charger once to re-trigger the BMS initialisation sequence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391892488282,"sku":"BWCS-MUT100SL-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391892521050,"sku":"BWCS-MUT100SL-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391892553818,"sku":"BWCS-MUT100SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MUT100SL-1.webp?v=1779142560","url":"https:\/\/batteryweb.com\/products\/xiaomi-mi-10t-lite-5g-replacement-battery-385v-4600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
