It fits SM-G355 and SM-G355H variants and slots into the same compartment as the original EB-BG355BBE cell. Capacity figure is 2000mAh as listed in the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G355 and SM-G355H compatibility:\u003c\/strong\u003e\n    Both handset variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The EB-BG355BBE part number covers all regional SM-G355 builds, so one cell fits both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full charge and discharge cycle on an SM-G355H. The BMS accepted the charge IC handshake without fault flags, and cell voltage held above 3.6V across a standard draw load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge precaution:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. This allows the fuel gauge IC to recalibrate its discharge curve against the new cell before high-current charging pushes amperage into an uncalibrated coulomb counter.\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 Core 2 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SM-G355 uses a coulomb-counter fuel gauge IC that builds its discharge model from previous cell behaviour. After a cell swap, the IC still references the old cell's voltage-to-capacity curve. When the modem transmits or the screen brightness peaks, current draw spikes and the new cell's voltage briefly dips below the IC's cutoff threshold — even though actual charge remains. The phone interprets the voltage dip as empty and shuts down. One full discharge-to-3.4V then full charge cycle forces the IC to rewrite its reference curve to match the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOS reporting wrong battery percentage after installing the EB-BG355BBE\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePercentage jumping or sticking at an incorrect value is a fuel gauge calibration issue, not a faulty cell. The Android battery stats file on the SM-G355 stores the old cell's discharge profile in the device partition. Clear the battery stats cache by fully draining the phone until it powers off, then charge uninterrupted to 100% with the device off. After two cycles of this, the reported percentage should track actual cell voltage within a normal margin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404221907034,"sku":"BWCS-SMG355XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404221939802,"sku":"BWCS-SMG355XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404221972570,"sku":"BWCS-SMG355XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG355XL-1.webp?v=1779369425","url":"https:\/\/batteryweb.com\/products\/samsung-sm-g355-replacement-battery-38v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
