It replaces a degraded or failed original battery, restoring full power delivery to the device. Capacity figure is 17.76Wh as rated from the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGT NEO5 platform fit:\u003c\/strong\u003e\n    The GT NEO5 uses a specific connector layout and BMS handshake tied to the BLP985 cell. The replacement matches the original voltage rail and connector pinout, so the charge IC and fuel gauge IC communicate correctly without triggering protection faults.\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 GT NEO5 unit. The BMS accepted the cell without tripping overcurrent protection, and the charge IC handed off cleanly between constant-current and constant-voltage phases at expected thresholds.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge calibration:\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 fast 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\"\u003eWhy the GT NEO5 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GT NEO5 uses a coulomb counter and fuel gauge IC that builds its model from learned discharge curves over time. When a new cell goes in, the IC is still referencing the old cell's curve — the voltage-to-capacity mapping no longer matches. The phone may show 80% while the actual state of charge is far lower, or vice versa. One full slow discharge down to automatic shutdown, followed by a complete charge, forces the IC to re-anchor its model to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% charge on the replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the modem, screen, or processor pulls peak current and the cell voltage drops sharply below the BMS cutoff threshold — even though the fuel gauge still reads 20–30%. A new cell with an uncalibrated fuel gauge IC has not yet mapped the voltage cliff of this specific cell's chemistry. The BMS reads the real cell voltage, sees it dip below 3.0V under load, and cuts output to protect the cell. After two to three full slow charge-discharge cycles, the fuel gauge IC tightens its model and the premature shutdowns stop.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391785205850,"sku":"BWCS-OPR985SL-1","price":40.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43391785238618,"sku":"BWCS-OPR985SL-2","price":47.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43391785271386,"sku":"BWCS-OPR985SL-3","price":52.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OPR985SL-1.webp?v=1779141909","url":"https:\/\/batteryweb.com\/products\/realme-gt-neo5-replacement-battery-74v-2400mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
