These devices lose usable capacity as their original cell degrades through repeated charge cycles — this battery restores full charge capacity. At 92.10 × 55.60 × 3.40 mm, it matches the original cell footprint exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM6 \/ M6s \/ MP1512 \/ MP1503 compatibility:\u003c\/strong\u003e\n    All four models share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell fits the entire platform 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 full charge and discharge on the M6 platform. The BMS accepted the cell, thermal regulation stayed within normal range, and the charge IC completed a full cycle without interruption.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use, 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 begins on 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 Meitu M6 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC is still reading the old cell's voltage curve. The new cell hits a voltage cliff under modem or display load at a point the gauge hasn't mapped yet. The phone interprets the voltage drop as a fault and shuts down — even though the cell has remaining capacity. One full discharge-charge cycle at standard rate lets the coulomb counter recalibrate, and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMeitu M6 reporting incorrect battery percentage after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe M6's fuel gauge IC stores a charge model calibrated to the original cell's internal resistance and capacity curve. A new cell has different impedance characteristics, so the stored model produces inaccurate percentage readings from the first charge. The fix is straightforward: drain the battery until the phone powers off, then charge uninterrupted to 100% without removing the cable early. After one full cycle, the coulomb counter resets its baseline to 3.85V nominal and percentage accuracy stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392077791322,"sku":"BWCS-MUT600SL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392077824090,"sku":"BWCS-MUT600SL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392077856858,"sku":"BWCS-MUT600SL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MUT600SL-1.webp?v=1779143621","url":"https:\/\/batteryweb.com\/products\/meitu-m6-replacement-battery-385v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
