It fits the full compatibility list including the i400 and i100 variants. Same voltage, same connector, same BMS handshake as the OEM unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-I400 and SCH-i100 platform fit:\u003c\/strong\u003e\n    These models share a 3.7V single-cell architecture with an identical connector pinout and BMS communication protocol — one cell covers both device lines 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 the SCH-I400 platform. The BMS accepted the cell without fault codes, and charge termination triggered correctly at 4.2V per cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one full discharge down to auto-shutdown, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean discharge curve to map against the new cell before it starts reporting percentages to the OS.\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\"\u003eA new cell has a slightly different internal resistance profile than the aged cell the fuel gauge IC was calibrated to. Under modem load or screen-on bursts, voltage sags faster than the OS expects, triggering a protection cutoff before the percentage counter reaches zero. The phone interprets this as a hard shutdown, not a low-battery event. One full uninterrupted discharge-charge cycle recalibrates the coulomb counter and eliminates most premature cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery compartment on first charge after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh high-impedance cell draws more voltage overhead from the charge IC on the first few cycles, which appears as mild heat near the battery bay. This is the charge IC compensating for the new cell's impedance — not a fault. Heat should reduce noticeably after two to three full cycles as internal resistance drops. If warmth persists beyond three cycles or the phone becomes hot to the touch, check that the battery connector is fully seated and not intermittently arcing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405049036890,"sku":"BWCS-SMI400SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405049069658,"sku":"BWCS-SMI400SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405049102426,"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\/samsung-sch-i400-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
