It fits the Samsung Galaxy A25 and Galaxy A25 5G, including variants SM-A256U and SM-A256U1\/DS. Capacity figure is taken directly from the product specification — 19.4Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalaxy A25 and A25 5G platform fit:\u003c\/strong\u003e\n    Both the standard A25 and the 5G variant share the same battery bay dimensions, connector pinout, and BMS handshake protocol — the EB-BA256ABS cell works across all SM-A256 sub-variants 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 an SM-A256U unit. The BMS accepted the handshake cleanly, charge IC ramped to full current without fault codes, and the protection circuit triggered correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-to-charge cycle. This gives the fuel gauge IC time to map the new cell's discharge curve before high-current charging is applied to 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\"\u003eSudden shutdown at 20–30% on the Galaxy A25 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. The Galaxy A25 runs a modem and an AMOLED panel simultaneously — both draw sharp current spikes. If the fuel gauge IC is still calibrated to the old cell's internal resistance curve, it misreads state-of-charge. The new cell drops below the system's minimum voltage rail under load before the OS registers low battery. Run one full discharge to automatic shutdown, then charge uninterrupted to 100% to force the coulomb counter to reset against the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after battery replacement on the A25\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first cycle after installation, the charge IC may not negotiate the fast-charge protocol until the BMS has completed one full handshake sequence with the new cell. This is normal behaviour — the phone defaults to standard 5V charging as a safety fallback. Disconnect the cable, power the phone off fully, then reconnect to a compatible 25W charger. If the fast-charge icon still does not appear, complete one full discharge cycle first; the BMS typically accepts the protocol without issue from the second charge onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391792316506,"sku":"BWCS-SMA250SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391792349274,"sku":"BWCS-SMA250SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391792382042,"sku":"BWCS-SMA250SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMA250SL-1.webp?v=1779142051","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-a25-replacement-battery-388v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
