It matches the OEM part number C936080250P and fits the physical footprint of the Neo X Plus battery bay. Voltage, connector, and BMS communication align to the stock configuration.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eNeo X Plus and N090U compatibility:\u003c\/strong\u003e\n    Both model designations refer to the same hardware platform. The battery connector, BMS handshake protocol, and 3.7V nominal voltage rail are identical across both. One cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the Neo X Plus platform. The BMS accepted the cell without error flags, and the charge IC cycled correctly through constant-current and constant-voltage phases to full termination.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes 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 Neo X Plus after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem. A new cell has a different internal resistance profile than the aged cell the fuel gauge IC was trained on. Under peak load — active LTE modem, screen at full brightness, or a background sync — the new cell's voltage drops faster than the IC expects. The phone interprets this as a critically low charge and cuts power. One full discharge-to-shutdown followed by a complete charge cycle resets the coulomb counter and maps the new cell's voltage curve accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not powering on after deep discharge in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the Neo X Plus sat unused for an extended period, the cell voltage may have dropped below 2.5V per cell — the threshold at which the BMS locks out to prevent damage. A standard charger will not wake a cell in this state. Connect the phone to a wall charger and leave it undisturbed for 20–30 minutes without pressing the power button. The charge IC will trickle current into the cell until voltage recovers to the BMS re-enable threshold, typically around 3.0V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392036438106,"sku":"BWCS-BLN090SL-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392036470874,"sku":"BWCS-BLN090SL-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392036503642,"sku":"BWCS-BLN090SL-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BLN090SL-1.webp?v=1779143085","url":"https:\/\/batteryweb.com\/products\/blu-neo-x-plus-replacement-battery-37v-2300mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
