It replaces OEM part HQ-7160SS when the original cell has degraded, swollen, or lost charge capacity. Dimensions are 94.00 × 67.00 × 4.10mm — confirm clearance before installation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalaxy A06 model variants:\u003c\/strong\u003e\n    The SM-A065F and SM-A065F\/DS share the same battery bay dimensions, connector pinout, and BMS handshake protocol — all accept the HQ-7160SS cell without modification. Regional variants differ only in radio bands, not power architecture.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the Galaxy A06's charge IC and confirmed the BMS negotiated correctly with Samsung's charge controller — charge current ramped as expected and thermal protection triggered at the correct threshold under load simulation.\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 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 Galaxy A06 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy A06 uses a coulomb counter tied to the fuel gauge IC, which builds its charge-curve model against the original cell over time. When you swap the cell, the IC still references the old cell's learned curve, so percentage readings drift — often showing 100% cut off early or reading 40% when the cell is nearly flat. One full discharge to auto-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter baseline. After that single cycle, percentage accuracy returns to normal. Do not use the phone during that calibration charge if possible.\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 happens when the modem or display draws a current spike that drops cell voltage below the BMS cutoff threshold — even though the gauge still shows charge remaining. A fresh Li-Polymer cell has slightly higher internal impedance on its first few cycles, making it more vulnerable to this voltage cliff. Run two or three full discharge-charge cycles to condition the cell and lower impedance. If shutdowns persist past cycle three, check that the battery connector is fully seated — a partial connection raises contact resistance and worsens voltage sag under load. Target resting voltage after a full charge should read 4.35–4.40V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391781797978,"sku":"BWCS-SMA065SL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391781830746,"sku":"BWCS-SMA065SL-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391781863514,"sku":"BWCS-SMA065SL-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMA065SL-1.webp?v=1779141909","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-a06-replacement-battery-388v-4850mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
