It fits the E1000, E1005, and X Dual SIM variants. When the original cell degrades and can no longer hold voltage under load, this replacement restores full device operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE1000 and E1005 platform fit:\u003c\/strong\u003e\n    Both variants share the same battery bay dimensions and connector pinout. The BLP607 footprint — 79.80 × 61.94 × 3.27mm — is specific to this chassis. A mismatched cell will not seat flat against the midframe, which stresses the connector and the display assembly above it.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on the OnePlus X board. The BMS accepted the cell without fault flags, and the charge IC held the correct 4.35V cutoff throughout. No thermal excursions were recorded during the constant-current phase.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. The fuel gauge IC on the OnePlus X calibrates its coulomb counter against the new cell's discharge curve. Running Dash Charge into an uncalibrated cell pushes current before the IC has mapped the correct reference points.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the OnePlus X reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe OnePlus X uses a fuel gauge IC that builds its capacity model from the original cell's charge and discharge history. When you install a fresh BLP607, that learned model no longer matches the new cell's actual voltage curve. The IC references stale data, so the percentage readout drifts — it may show 40% and then drop to 10% within minutes. One full discharge to auto-shutoff followed by a complete charge to 100% lets the coulomb counter reset against the new cell and restores accurate reporting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff failure, not a capacity problem. Under peak modem load or a screen-on burst, the cell's terminal voltage drops faster than the fuel gauge expects, triggering a low-voltage protection cutoff before the percentage reaches zero. It happens most often in the first few cycles on a new cell before the fuel gauge IC has recalibrated. Run two complete discharge-charge cycles without fast charging, then confirm the shutdown threshold shifts. If the phone still cuts out above 15%, check that the cell connector is fully seated — a partial connection increases contact resistance and amplifies voltage sag under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404133302362,"sku":"BWCS-OPA300SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404133335130,"sku":"BWCS-OPA300SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404133367898,"sku":"BWCS-OPA300SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPA300SL-1.webp?v=1779369061","url":"https:\/\/batteryweb.com\/products\/oneplus-oneplus-x-replacement-battery-38v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
