It fits the same physical envelope — 96.17 × 37.60 × 3.20mm — and connects to the same logic board connector as the factory unit. Capacity is rated at 6.88Wh, matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA1586, A1589, A1549 compatibility:\u003c\/strong\u003e\n    These three model numbers share the same battery bay dimensions, connector pinout, and BMS handshake protocol. One cell covers all three variants 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 charge and discharge on an iPhone 6 logic board. The BMS accepted the cell, charge IC engaged correctly, and the fuel gauge IC registered the new capacity without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after installation:\u003c\/strong\u003e\n    On first use, disable any fast-charge accessories and run one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the coulomb counter a clean reference cycle against the new cell's discharge curve before high-current charging begins.\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  \u003cp class=\"bpw-desc-p\"\u003eThe iPhone 6 fuel gauge IC holds a discharge curve model built from hundreds of cycles on the old, degraded cell. When a new cell arrives, its internal resistance is lower and its voltage cliff sits at a different point. The fuel gauge predicts shutdown too late, so the phone cuts power while the reported percentage still reads 20–30%. This is not a fault in the replacement cell — it is a calibration mismatch. Run one full discharge to automatic shutdown followed by a full uninterrupted charge to 100%, and the coulomb counter will rebuild its model against the new cell's actual curve.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eiPhone 6 not powering on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells self-discharge during storage. If this battery has been sitting in a warehouse or drawer, its resting voltage may have dropped below 2.5V per cell — the threshold at which the BMS locks out to prevent damage. The phone will show no response to the power button and no charge indicator on the screen. Connect a known-good Lightning cable and leave it on charge for 15–20 minutes before attempting to power on; the charge IC will trickle current into the cell until the BMS releases its lockout, typically above 2.8V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43404250054746,"sku":"BWCS-IPH600SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43404250087514,"sku":"BWCS-IPH600SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43404250120282,"sku":"BWCS-IPH600SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPH600SL-1.webp?v=1779369448","url":"https:\/\/batteryweb.com\/products\/apple-iphone-6-replacement-battery-382v-1800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
