It replaces part numbers EB504465YZ, EB504465IZ, and SAMINTBATS5. Fit models include the SCH-I400, i400 Continuum, Gem i100, and SCH-i100 among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-I400 and Gem i100 platform compatibility:\u003c\/strong\u003e\n    These models share the same 3.7V cell format, connector pinout, and BMS handshake protocol. One replacement cell covers the full platform 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 SCH-I400. The BMS accepted charge current correctly, thermal cutoff triggered at expected thresholds, and the protection circuit responded normally to over-discharge events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installing this cell, disable fast charging and run one complete discharge-to-charge cycle before normal use. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\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 SCH-I400 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still calibrated to the old cell's discharge curve. When the modem or screen pulls current, the new cell's voltage drops faster than the IC expects at that state of charge. The phone reads adequate capacity but the cell voltage falls below the BMS cutoff threshold — typically around 3.0V — and the device shuts off. One full discharge-to-charge cycle resets the coulomb counter and corrects the percentage reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSCH-I400 shows incorrect battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Android fuel gauge IC stores a learned discharge profile from the old cell. A new cell with different internal resistance reads differently under load, so the reported percentage drifts from actual charge level. Percentage may jump erratically or plateau at unexpected values. Charge the phone to 100%, let it discharge fully until shutdown, then charge back to 100% without interruption — this forces the IC to recalibrate against the new cell's actual voltage curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405048938586,"sku":"BWCS-SMI400SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405048971354,"sku":"BWCS-SMI400SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405049004122,"sku":"BWCS-SMI400SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI400SL-1.webp?v=1779369898","url":"https:\/\/batteryweb.com\/products\/verizon-sch-i400-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
