It fits the 5.5-inch model across variants A1522, A1593, and related revisions. Install it when the original cell no longer holds charge or causes unexpected shutdowns.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eiPhone 6 Plus compatibility (A1522 \/ A1593):\u003c\/strong\u003e\n    These model numbers share the same logic board connector, physical cell envelope (119.30 × 48.40 × 3.60mm), and BMS handshake protocol. The 3.82V nominal rail matches what the iPhone 6 Plus charge IC expects — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through a full discharge-charge cycle on an iPhone 6 Plus logic board. The BMS communicated correctly with the charge IC, and charge termination triggered at the expected 4.35V cutoff without manual override.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After installation, disable fast charging and run one complete discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the coulomb counter one clean cycle to map the new cell's discharge curve before you return to normal use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the iPhone 6 Plus reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The iPhone then reads state-of-charge off the wrong map, so the displayed percentage drifts away from reality. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter and aligns it to the new cell.\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 cell voltage drops sharply under high-current load — modem transmit bursts and screen-on draw can pull enough current to drag voltage below the BMS cutoff threshold, even when the gauge still shows charge remaining. The original fuel gauge calibration predicts a gentler slope, so it doesn't warn iOS in time. Run two full recalibration cycles and the shutoffs typically stop. If they continue past two cycles, check that cell-to-connector solder tabs are fully seated — a high-contact resistance point causes the same voltage cliff at the connector before the cell itself is depleted.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392076709978,"sku":"BWCS-IPH610XL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392076742746,"sku":"BWCS-IPH610XL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392076775514,"sku":"BWCS-IPH610XL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IPH610XL-1.webp?v=1779143620","url":"https:\/\/batteryweb.com\/products\/apple-iphone-6-plus-replacement-battery-382v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
