It fits SM-G935A, SM-G935F, SM-G935P, and related SM-G935 variants. Voltage matches the S7 Edge power management IC exactly — no step-up or step-down conversion required.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-G935 series compatibility:\u003c\/strong\u003e\n    All SM-G935 variants share the same 3.85V power rail, the same physical footprint (97.70 × 42.06 × 4.85mm), and the same flex connector pinout. The battery management system talks to the same charge IC across every carrier variant, so one cell covers the full range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on an SM-G935F and monitored BMS handshake, charge termination, and thermal cutoff thresholds. The protection circuit responded correctly at both low-voltage cutoff and high-current draw during simultaneous screen-on and LTE activity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first cycle:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. The Galaxy S7 Edge coulomb counter is calibrated to the old cell's discharge curve — a full slow cycle resets that reference so percentage readings stay accurate from the second charge onward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the S7 Edge reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Galaxy S7 Edge uses a coulomb-counting fuel gauge IC that builds its percentage model from the previous cell's charge and discharge history. When you install a new cell, that stored model no longer matches the actual chemistry it is measuring. The IC will over- or under-report state of charge until it observes at least one full discharge-charge cycle on the new cell. After that cycle, the fuel gauge reanchors its curve to the replacement cell and percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage-cliff failure, not a capacity problem. Under combined modem transmission and display load, the cell voltage drops sharply below the threshold the power management IC will sustain — even when the reported percentage looks safe. The phone interprets the voltage drop as a critical low-power event and shuts down instantly. To confirm this is the cause, charge to 100%, then run the screen at full brightness with mobile data active and watch for shutdown above 25% — if it cuts out, let the phone discharge fully to 0%, then charge uninterrupted to 100% to give the fuel gauge a clean calibration cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392106430554,"sku":"BWCS-SMG935SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392106463322,"sku":"BWCS-SMG935SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392106496090,"sku":"BWCS-SMG935SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMG935SL-1.webp?v=1779143797","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s7-edge-replacement-battery-385v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
