It slots directly into the removable battery bay and connects via the standard Samsung pogo-pin contact strip. Voltage and capacity match OEM spec: 3.85V nominal, 11.55Wh rated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eChina Mobile variant compatibility:\u003c\/strong\u003e\n    The SM-N9109W and SM-N9106W carry a dual-SIM modem stack that pulls higher current spikes than single-SIM Note 4 models. This cell's BMS is rated for the same continuous discharge curve as the original EB-BN916BBC, so the modem handshake and voltage rail stay stable under simultaneous SIM polling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full discharge-to-cutoff and charge-to-termination sequence on SM-N910F hardware. The BMS held the 4.35V charge termination threshold and tripped the low-voltage cutoff cleanly at 3.0V with no mid-cycle drops or false protection events.\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 at standard current. This lets the fuel gauge IC map the new cell's discharge curve before the charge IC pushes higher current into an uncalibrated state.\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 is a voltage cliff issue, not a capacity fault. The fuel gauge IC is still running the coulomb-counter model it built against the old, degraded cell. When the new cell hits a steep voltage drop under modem or display load, the phone's protection circuit reads it as a critical-low event and shuts down — even though the reported percentage looks safe. One full discharge-charge cycle forces the IC to rebuild its internal model against the new cell's actual voltage curve. After that cycle, shutdowns at 20–30% typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB fast charge not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's adaptive fast charge handshake runs through the charge IC on the motherboard, not the battery BMS — but the IC checks cell impedance before stepping up voltage. A new cell starts with slightly higher impedance than a broken-in cell, so the charge IC may default to standard 5V on the first one or two cycles. This is not a fault with the battery or the charger. Use the original Samsung adaptive charger, complete one standard-rate charge cycle, and the IC will accept the fast-charge protocol on the next connection.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404224954458,"sku":"BWCS-SMN916XL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404224987226,"sku":"BWCS-SMN916XL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404225019994,"sku":"BWCS-SMN916XL-3","price":30.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-note-4-china-mobile-replacement-battery-385v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
