It fits the standard battery bay without modification and connects via the original three-contact terminal strip. OEM part numbers covered include B500AU, B500BU, EB-B500BU, and EB-B500BE.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS4 Mini platform fit:\u003c\/strong\u003e\n    All S4 Mini variants share the same battery bay dimensions and terminal pinout — 69.10 x 50.90 x 4.20mm with a three-pin contact layout. The voltage rail and BMS handshake are identical across GT-I9190, GT-I9195, and SGH-I257, so one cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell in a GT-I9190 unit and confirmed BMS handshake on first insertion. The charge IC accepted the cell immediately and the protection circuit tripped correctly at both high-voltage and low-voltage thresholds during discharge cycling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to system shutdown followed by a complete uninterrupted charge to 100% before enabling fast charging. This gives the Galaxy S4 Mini's fuel gauge IC time to map the new cell's discharge curve before high-current charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the S4 Mini reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S4 Mini uses a coulomb counter in its fuel gauge IC that builds a capacity model from charge and discharge history. When you install a new cell, that model still references the old cell's degraded curve, so the percentage reading is immediately out of sync. The IC needs at least one full discharge-to-shutdown and charge-to-100% cycle to reset its reference points against the new cell. Until that cycle completes, the reported percentage can run high or low by 10–20%, and the low-battery warning may fire at the wrong point.\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 below the load threshold under peak demand — typically during LTE data bursts or screen-on transitions — even though the fuel gauge still shows charge remaining. On a new, uncalibrated cell the voltage cliff appears earlier in the discharge curve than the IC expects. The fix is to complete two full discharge-charge cycles so the coulomb counter recalibrates its end-of-discharge voltage reference. After calibration, the shutdown point should stabilise above 3.4V per cell under normal load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404322766938,"sku":"BWCS-SMI257SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404322799706,"sku":"BWCS-SMI257SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404322832474,"sku":"BWCS-SMI257SL-3","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI257SL-1.webp?v=1779369779","url":"https:\/\/batteryweb.com\/products\/samsung-gt-i9190-replacement-battery-37v-1400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
