It fits the SCH-i110, Illusion i110, and Galaxy S i500. Slot it in the same way the original came out — same connector, same form factor at 58.80 × 45.50 × 5.00mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSCH-i110 and Illusion compatibility:\u003c\/strong\u003e\n    These models share the same battery bay dimensions, connector pinout, and BMS handshake protocol, which is why one cell covers the full range. The charge IC on the motherboard communicates with the BMS over the same voltage rail at 3.7V nominal.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the SCH-i110 platform. The BMS responded correctly to charge termination, and the protection circuit tripped at expected low-voltage thresholds without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fuel gauge reset:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging begins on 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\"\u003eWhy the SCH-i110 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC on the SCH-i110 stores a learned discharge curve from the previous cell. When a new cell goes in, the IC is still referencing the old curve — so it maps voltage readings to incorrect state-of-charge percentages. This shows up as percentage jumps, inflated readings, or the bar sitting stuck at one level for an unusually long stretch. One full discharge down to auto-shutdown followed by an uninterrupted charge to 100% forces the coulomb counter to rebuild its model against the new cell's actual characteristics.\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 cell voltage drops sharply under load — the modem transmitting or the screen at full brightness draws a current spike the cell cannot sustain at that state of charge. The voltage briefly dips below the BMS cutoff threshold, triggering an immediate shutdown even though the gauge showed charge remaining. It is a voltage-cliff issue, not a capacity defect. After the first full calibration cycle, the fuel gauge learns where that cliff sits and the percentage display will reflect it accurately — typically flagging low battery before the BMS trips.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405045203034,"sku":"BWCS-SMI110XL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405045235802,"sku":"BWCS-SMI110XL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405045268570,"sku":"BWCS-SMI110XL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI110XL-1.webp?v=1779369859","url":"https:\/\/batteryweb.com\/products\/samsung-sch-i110-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
