It fits SM-S908B\/DS, SM-S906W, SM-S908E\/DS, and related variants. Swap it in when your original EB-BS908ABY has degraded past usable capacity.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS22 Ultra 5G platform fit:\u003c\/strong\u003e\n    The SM-S908 series shares a single battery bay, connector pinout, and BMS handshake across regional variants. The same cell services the modem, display, and S Pen digitiser rail without a voltage step-down conflict.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on an SM-S908B\/DS. The BMS accepted the cell without a fault flag, and the charge IC stepped through trickle, CC, and CV phases correctly.\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 for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated state.\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 a replacement cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a discharge curve the phone's coulomb counter hasn't seen yet. When the modem fires a 5G burst or the display peaks, the phone draws a spike the fuel gauge misreads as a voltage cliff. The system shuts down to protect the cell even though charge remains. One full slow discharge-charge cycle resets the coulomb counter baseline and eliminates most of these false cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not triggering on the first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the charge IC on the S22 Ultra 5G defaults to standard 5W charging on the first session while it reads the new BMS parameters. This is not a fault — it is a handshake delay. Disconnect the cable, wait 10 seconds, and reconnect. If fast charge still doesn't trigger, complete one full standard charge cycle first and it will re-enable at the next session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391866896474,"sku":"BWCS-SMS908SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391866929242,"sku":"BWCS-SMS908SL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391866962010,"sku":"BWCS-SMS908SL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMS908SL-1.webp?v=1779142430","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s22-ultra-5g-replacement-battery-385v-4550mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
