It fits where the original cell sits and connects via the same flex-cable ribbon connector. Swap it in when the original cell no longer carries enough charge through a full day of use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model fit — Note 10 and X30 Max:\u003c\/strong\u003e\n    Both handsets share the same battery bay dimensions (102.65 × 72.24 × 3.74 mm), the same 3.85V nominal rail, and a compatible BMS communication protocol — which is why one cell covers both platforms.\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 Note 10 unit. The BMS accepted the charge handshake without fault flags, and cell voltage held within the expected window across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast-charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable Honor SuperCharge for one complete discharge-charge cycle at standard 5V\/2A. This lets the fuel gauge IC map 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\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC in the Note 10 stores a discharge model built from cycles on the original cell. When a new cell goes in, that stored model is stale — the IC miscalculates remaining capacity and cuts power before the cell is actually empty. The phone shuts down because the software-reported state of charge hits zero, even though cell voltage may still be above 3.5V. One full discharge-to-shutdown followed by an uninterrupted charge to 100% forces the coulomb counter to reset against the new cell's actual curve. After two to three of these cycles, percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone warm near the battery bay on the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh lithium-polymer cell has higher internal impedance than a cell that has been through formation cycles. The charge IC pushes current into higher resistance, which generates more heat than you would see with a broken-in cell. This is normal for the first three to five charges and tapers off as the cell cycles down in impedance. If the back of the phone exceeds uncomfortable-to-touch warmth or the charge IC throws a thermal fault — shown as charging paused in the status bar — drop to a 5W charger for that session and let the cell complete the cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392014647386,"sku":"BWCS-HUT220SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392014680154,"sku":"BWCS-HUT220SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392014712922,"sku":"BWCS-HUT220SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HUT220SL-1.webp?v=1779142904","url":"https:\/\/batteryweb.com\/products\/honor-note-10-replacement-battery-385v-4900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
