It uses the same connector and matches the physical footprint at 56.40 × 50.80 × 11.00mm. Drop it in when the original cell no longer holds enough charge to get through normal use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSkyrocket and SGH-I727 fit:\u003c\/strong\u003e\n    Both model names refer to the same AT\u0026amp;T LTE device. The battery bay, connector pin-out, and BMS communication protocol are identical across both designations — one cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the SGH-I727. The BMS accepted the cell without triggering a protection fault, and the charge IC negotiated correctly with the phone's onboard power management.\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 and run one complete discharge-charge cycle. The SGH-I727's fuel gauge IC is calibrated to the old cell's discharge curve. Giving it one unconstrained cycle against the new cell prevents the coulomb counter from mis-reading state-of-charge from day one.\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 Skyrocket after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SGH-I727 modem and screen pull significant current spikes. A fresh cell with a slightly different internal resistance curve can cause voltage to sag below the BMS cutoff threshold before the fuel gauge reads zero. The phone interprets this as a hard fault and shuts down even though the reported percentage is well above empty. One full discharge-charge cycle lets the fuel gauge IC map the new cell's actual voltage cliff and adjust the low-voltage warning point accordingly. After calibration, shutdowns at 20–30% typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge in storage. If this battery sat long enough before installation, the cell voltage may have dropped below 2.5V — the point where the BMS locks out to prevent damage from over-discharge. The SGH-I727 will show no response at all: no boot, no charging indicator. Connect it to a wall charger, not a USB port, and leave it for 20–30 minutes without pressing the power button. A wall adapter can push enough trickle current to bring the cell back above 2.8V, at which point the BMS releases the lockout and normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405047857242,"sku":"BWCS-SMI727XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405047890010,"sku":"BWCS-SMI727XL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405047922778,"sku":"BWCS-SMI727XL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI727XL-1.webp?v=1779369899","url":"https:\/\/batteryweb.com\/products\/samsung-skyrocket-replacement-battery-37v-2800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
