It fits SM-A057M, SM-A057M\/DS, SM-A057F\/DS, and related variants. Use it when the original cell has degraded, holds less charge than expected, or fails to power the phone through normal use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-A057 series fit:\u003c\/strong\u003e\n    All SM-A057 variants share the same battery bay geometry, connector pitch, and BMS handshake. The SLC-51 and GH81-24363A part numbers map to the same physical cell across these models — same flex connector, same NTC thermistor position, same charge IC protocol.\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 SM-A057 platform. The BMS accepted the cell without error flags, the charge IC negotiated correctly, and the fuel gauge IC tracked state-of-charge across the full curve without dropout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge tip:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and complete one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell — preventing early percentage drift.\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 replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still using the discharge curve from the old, degraded cell. The new cell has a steeper voltage cliff at lower states of charge, and the IC miscalculates remaining capacity. Under screen-on or modem load, the cell voltage drops below the BMS cutoff threshold faster than the percentage reading suggests. One full discharge-to-cutoff followed by a full charge resets the coulomb counter and aligns the curve — after that cycle, shutdowns at mid-percentage typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn first charge after installation, the charge IC may not negotiate Samsung's fast charge protocol if the new cell's BMS hasn't completed its initialisation handshake. The phone charges at standard 5V\/1A instead of the higher rate. This usually clears after the battery reaches above 15% on the first charge cycle. If fast charge still doesn't activate after a full cycle, check that the charger output matches the required 9V\/1.67A spec — a standard 5W charger won't trigger the protocol regardless of cell state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391797067866,"sku":"BWCS-SMA057SL-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391797100634,"sku":"BWCS-SMA057SL-2","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391797133402,"sku":"BWCS-SMA057SL-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMA057SL-1.webp?v=1779142182","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-a05s-2023-replacement-battery-385v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
