It fits SM-N910W8, SM-N910R4, SM-N910L, and over a dozen other Note 4 variants. Use OEM part numbers EB-BN910BBE, EB-BN910BBK, EB-BN910BBU, or EB-BN910BBT to confirm fitment before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNote 4 variant compatibility:\u003c\/strong\u003e\n    Samsung released the Note 4 across multiple carrier and regional variants — SM-N910W8 for Canadian carriers, SM-N910R4 for US regional networks, SM-N910L for LG U+ in Korea. All share the same battery bay dimensions (98.80 × 41.40 × 5.60mm), the same 3.85V nominal voltage rail, and the same connector layout, so one cell covers the full lineup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an SM-N910 unit through three full discharge-charge cycles. The BMS accepted charge current without triggering over-voltage protection, and the fuel gauge IC tracked state-of-charge correctly by the second cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard current. This gives the fuel gauge IC a clean reference curve against the new cell before adaptive charging algorithms push higher current into 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 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 discharge curve from the old cell in non-volatile memory. When a new cell goes in, the stored curve no longer matches actual cell behaviour, and the IC miscalculates remaining capacity. Under load — specifically when the Snapdragon 805's modem and display draw peak current simultaneously — the real cell voltage drops below the 3.4V cutoff before the percentage reaches zero. The phone shuts down at what looks like 20–30% remaining. One full discharge to automatic shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and brings percentage readings back into alignment.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage at roughly 2–5% per month. If this battery shipped or sat unused long enough for cell voltage to drop below 2.5V, the BMS enters a lockout state to prevent damage and will refuse to accept a normal charge current. The phone shows nothing — no charging animation, no LED. Connect to a wall adapter rated at least 5V\/1A and leave it for 20–30 minutes without pressing the power button; the charger IC delivers a trickle recovery current that brings the cell above the 2.8V re-initialisation threshold, after which normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404234948698,"sku":"BWCS-SMN917SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404234981466,"sku":"BWCS-SMN917SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404235014234,"sku":"BWCS-SMN917SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMN917SL-1.webp?v=1779369465","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-note-4-replacement-battery-385v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
