It fits the SM-C7000 and Galaxy C7 Duos variants using the same connector and BMS pinout. Capacity figure is taken from product data — not estimated from third-party sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGalaxy C7 series compatibility:\u003c\/strong\u003e\n    The C7, C7 Duos, C7 Pro Duos, and SM-C7000 all share the same battery bay dimensions, connector orientation, and BMS communication protocol. That common platform is why one cell covers this entire model group — not guesswork on our part.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on a Galaxy C7 unit. The BMS handshake completed normally, charge IC accepted the cell without error flags, and voltage held above 3.6V under sustained screen-on and modem load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle fast charge protocol:\u003c\/strong\u003e\n    On first use after installation, disable Samsung Adaptive Fast Charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current fast charging pushes current into an uncalibrated cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Galaxy C7 reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSamsung's fuel gauge IC builds a charge map against the original cell over hundreds of cycles. When a new cell goes in, that map no longer matches the actual discharge curve. The IC keeps reading state-of-charge against old data, so the percentage shown on screen drifts from reality. One full discharge down to auto-shutdown followed by an uninterrupted charge to 100% forces the IC to re-anchor its coulomb counter 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 fuel gauge IC's voltage map is still calibrated to the old cell's internal resistance profile. Under modem or display load, the new cell hits a voltage cliff the IC wasn't expecting, and the phone cuts power before the displayed percentage reaches zero. It is not a faulty cell — it is an uncalibrated gauge. Run two full discharge-to-shutdown and charge-to-100% cycles without interruption. After the second cycle, the IC's threshold map resets and the shutdown floor drops back to the correct level near 3.2V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392082411610,"sku":"BWCS-SMC700XL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392082444378,"sku":"BWCS-SMC700XL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392082477146,"sku":"BWCS-SMC700XL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMC700XL-1.webp?v=1779143638","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-c7-replacement-battery-385v-3300mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
