It matches the OEM part numbers 616-0804, 616-0805, 616-0806, and 616-0809. At 96.90 × 39.00 × 3.50mm, it fits the original battery bay without modification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPhone 6 model coverage:\u003c\/strong\u003e\n    The A1586, A1549, and A1589 variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol — one cell covers all three without adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on an iPhone 6 A1586. The BMS communicated correctly with the charge IC, held voltage through screen-on and modem-active load, and passed Apple's battery health check in Settings.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging for the first complete discharge-charge cycle. The fuel gauge IC calibrates its coulomb counter against the new cell's discharge curve — skipping this can leave the IC reading the old curve and reporting inaccurate percentages for several days.\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 iPhone 6 after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe iPhone 6's fuel gauge IC stores a charge curve from the previous cell in non-volatile memory. When a new cell goes in, the stored curve no longer matches the actual discharge profile of the replacement. Under high-current loads — active LTE, screen at full brightness, GPS — the cell voltage dips faster than the IC expects, triggering a protection cutoff before the displayed percentage reaches zero. One full discharge-charge cycle forces the coulomb counter to rebuild its curve against the new cell. After that cycle, the 20–30% shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiPhone 6 not powering on after the battery sat discharged in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells enter BMS lockout when voltage drops below approximately 2.5V per cell — a state triggered by extended storage in a discharged condition. In lockout, the phone shows nothing on screen and does not respond to the power button. Connect the phone to a wall adapter rated at 5V\/1A and leave it for 20–30 minutes without pressing any button — the charge IC trickle-charges the cell back above the BMS re-enable threshold. Once the Apple logo appears, the BMS has released lockout and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392076808282,"sku":"BWCS-IPH600XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392076841050,"sku":"BWCS-IPH600XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392076873818,"sku":"BWCS-IPH600XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPH600XL-1.webp?v=1779143620","url":"https:\/\/batteryweb.com\/products\/apple-iphone-6-replacement-battery-382v-2160mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
