It matches OEM part numbers EB-BN916BBC and EB-BN916BBE. It fits directly into the original battery bay with the same connector and cell dimensions: 98.48 x 38.9 x 5.6 mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-N910 series compatibility:\u003c\/strong\u003e\n    The China Mobile Note 4 variants and the SM-N910F share the same battery bay geometry, connector pinout, and BMS handshake protocol — which is why one cell covers multiple model numbers across this sub-family.\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-discharge cycles on the SM-N910 platform. The BMS accepted the cell without a protection trip, and the charge IC completed a full constant-current to constant-voltage taper cycle without interruption.\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-charge cycle at standard rate. This gives the fuel gauge IC a clean discharge curve to map against the new cell — before high-current charging pushes amps 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 Note 4 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Note 4's fuel gauge IC stores a learned discharge curve from the previous cell. When a new cell is installed, that stored curve no longer matches actual cell voltage under load. The modem radio and display together can pull enough current to cause a sharp voltage sag — the IC sees a reading below its cutoff threshold and shuts the device down, even though the new cell still holds charge. One full standard-rate discharge-charge cycle forces the coulomb counter to relearn the new cell's voltage floor, typically settling cutoff near 3.4–3.5V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charge sessions\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh high-impedance cell generates more heat than a broken-in one during the initial charging sessions. The charge IC on the Note 4 runs constant-current phase longer against a new cell because internal resistance is slightly higher out of the box. This is normal and typically settles after three to five cycles as internal resistance drops. If the device stays warm beyond the fifth cycle, check that the back cover is seated flush — trapped heat has no exit path through a misaligned cover.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404243894362,"sku":"BWCS-SMN916SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404243927130,"sku":"BWCS-SMN916SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404243959898,"sku":"BWCS-SMN916SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMN916SL-1.webp?v=1779369465","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-note-4-china-mobile-replacement-battery-385v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
