It fits the SM-S901B\/DS, SM-S901U, SM-S901U1, and related S901 variants. The replacement restores full charge capacity to phones where the original cell has degraded or failed to hold a charge.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS901 platform compatibility:\u003c\/strong\u003e\n    Every SM-S901 variant shares the same battery bay dimensions, connector pinout, and BMS handshake protocol. The fuel gauge IC on the S22 mainboard reads cell impedance on first boot — this cell presents within the expected range for the S901 charge controller to accept it without flagging a hardware mismatch.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell on an SM-S901U through three full discharge-charge sequences. The BMS accepted the cell on first connection, charge termination triggered correctly at 4.35V, and the protection circuit tripped cleanly at the low-voltage cutoff threshold without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after install:\u003c\/strong\u003e\n    On first use after installation, disable fast charging for one complete discharge-charge cycle. The S22's fuel gauge IC is calibrated to the old cell's discharge curve — running one slow cycle at standard charge current lets the coulomb counter build an accurate state-of-charge map before fast charging pushes higher 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\"\u003eSudden shutdown at 20–30% on the replacement cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S22 shuts down under modem and display load when cell voltage drops below the mainboard's cutoff threshold — even if the OS shows remaining charge. A new cell with an uncalibrated fuel gauge IC can show 25% on screen while actual open-circuit voltage is already near 3.5V under load. This is a voltage cliff caused by the coulomb counter not yet knowing the new cell's discharge curve. Run two full cycles — discharge to automatic shutdown, then charge to 100% on standard charging — and the percentage reporting stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD fast charge not activating on first cycle after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter a cell swap, the S22's charge IC sometimes holds the new battery at trickle current through the first partial charge rather than handshaking with the USB-PD adapter. This happens because the charge controller detects an unconditioned cell and defaults to a conservative pre-charge mode. Disconnect the cable, power the phone fully off, then reconnect to a Samsung-rated 25W adapter — the charge IC renegotiates the USB-PD contract on a cold start and fast charging resumes at the correct current. Confirm by checking that the phone displays \"Fast Charging\" within 10 seconds of plugging in.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391850446938,"sku":"BWCS-SMS901SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391850479706,"sku":"BWCS-SMS901SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391850512474,"sku":"BWCS-SMS901SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMS901SL-1.webp?v=1779142388","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s22-5g-replacement-battery-385v-3600mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
