It replaces OEM part BL-N5000D and fits the original battery bay without modification. Capacity matches the factory spec at 5000mAh (19Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM6 and GN8003 compatibility:\u003c\/strong\u003e\n    Both the M6 and GN8003 share the same battery bay dimensions, voltage rail, and BMS connector pinout. The BL-N5000D form factor — 91.70 × 64.40 × 4.50 mm — fits either handset without adapter or modification.\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 a GIONEE M6 unit. The BMS accepted the handshake on first connection, charge IC registered the cell correctly, and the fuel gauge IC began tracking state-of-charge without manual intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle calibration tip:\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\"\u003eWhy the M6 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GIONEE M6 uses a coulomb counter in the fuel gauge IC that builds its reference model from the original cell's discharge curve. When a new cell goes in, that stored model no longer matches the actual cell chemistry and capacity. The OS reads from the fuel gauge — not the cell directly — so it reports percentages calibrated to the old cell. One full discharge from 100% down to automatic shutdown, followed by a full charge with fast charging disabled, forces the IC to rewrite its reference curve against the new cell.\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 problem. Under heavy load — active LTE modem, bright screen, or simultaneous app activity — the cell voltage drops sharply below what the fuel gauge IC predicted at that state-of-charge. The phone's protection circuit triggers shutdown before the reported percentage hits zero. Run one unconditioned discharge-charge cycle first. If shutdowns persist after calibration, check that cell voltage at shutdown reads above 3.4V using a battery diagnostic app — anything lower points to a BMS trip, not a gauge error.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392084738138,"sku":"BWCS-GNN803SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392084770906,"sku":"BWCS-GNN803SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392084803674,"sku":"BWCS-GNN803SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GNN803SL-1.webp?v=1779143685","url":"https:\/\/batteryweb.com\/products\/gionee-m6-replacement-battery-38v-5000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
