It replaces the original cell when the existing battery degrades, swells, or can no longer hold a usable charge. Capacity figures come from product data: 1500mAh \/ 5.55Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eWeMove Miracle fit:\u003c\/strong\u003e\n    The WeMove Miracle uses a removable slim-pack cell at 3.7V nominal. This replacement matches the original cell's dimensions (55.90 × 53.80 × 5.06mm), voltage rail, and connector orientation so it seats without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a smartphone test rig. The BMS held cutoff correctly at the low-voltage threshold and accepted a full charge without tripping protection. Capacity tracked within spec across the first three cycles.\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 rate. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated register.\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% after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still running calibration data from the old, degraded cell. When the new cell's voltage drops under modem or screen load, the IC misreads remaining capacity and signals a shutdown before the cell is actually depleted. The fix is one full uninterrupted discharge-charge cycle without fast charging enabled. After that cycle, the coulomb counter resets against the new cell's actual discharge curve and the percentage readings stabilise.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery during the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new high-impedance cell generates more heat during the initial charge cycles than a broken-in cell does. The charge IC has to work harder to push current into a cell it hasn't yet characterised. This is normal for the first two to three cycles and typically settles as internal resistance drops. If the phone remains unusually warm after the third full charge, check that the replacement cell is seated flat with no gap at the connector — poor contact increases resistance and sustains the heat.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404215189594,"sku":"BWCS-WKS008SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404215222362,"sku":"BWCS-WKS008SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404215255130,"sku":"BWCS-WKS008SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-WKS008SL-1.webp?v=1779369426","url":"https:\/\/batteryweb.com\/products\/ngm-wemove-miracle-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
