It restores power to calls, messaging, and onboard applications when the factory cell can no longer hold a usable charge. Voltage and capacity match the OEM specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eN95 and N95 8GB compatibility:\u003c\/strong\u003e\n    Both handsets run the same voltage rail and use an identical battery connector and BMS handshake. One cell covers both variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled the ML0639 through charge and discharge on an N95 unit. The BMS accepted the cell without error flags, and the charge IC reached full termination voltage cleanly on each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    On first use, disable any power-saving shortcuts and let the phone run one complete discharge down to auto-off, then charge uninterrupted to 100%. This lets the N95 fuel gauge IC map the new cell's actual discharge curve before it begins reporting percentage to the OS.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the N95 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Nokia N95 uses a fuel gauge IC that builds a discharge model against the cell it was last calibrated to. Swap in a new cell and that model no longer matches the actual chemistry. The gauge reads voltage and translates it into a percentage using stale data, so the number on screen drifts from reality. One full uninterrupted discharge-to-charge cycle resets the coulomb counter and re-anchors the percentage to the new cell's real curve.\u003c\/p\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. Under combined load — WLAN radio, display, and GPS active simultaneously — the N95 draws enough current to pull cell voltage below the BMS cutoff threshold before the fuel gauge hits 0%. The phone shuts off hard to protect the cell. Run that first full calibration cycle with typical app usage active, and the gauge will learn where the real voltage floor sits under that load. If shutdowns persist past two full cycles, measure resting cell voltage after shutdown — it should be above 3.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405136592986,"sku":"BWCS-NK4DSL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405136625754,"sku":"BWCS-NK4DSL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405136658522,"sku":"BWCS-NK4DSL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK4DSL-1.webp?v=1779370279","url":"https:\/\/batteryweb.com\/products\/m-life-replacement-battery-37v-950mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
