It fits SM-S906B and SM-S906B\/DS variants and slots into the original battery bay using the same connector and form factor. Capacity is 4000mAh (15.52Wh), matching the OEM cell specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSM-S906B series fit:\u003c\/strong\u003e\n    All SM-S906B variants share the same voltage rail, battery connector pinout, and BMS handshake protocol. This cell communicates correctly with the Galaxy S22 Plus 5G charge IC and fuel gauge IC without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an SM-S906B unit. The BMS accepted the cell on first connection, charge termination triggered at the correct cutoff voltage, and the fuel gauge IC began tracking coulomb count within the first full cycle.\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 complete one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before fast charging pushes high 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 Galaxy S22 Plus 5G after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe S22 Plus 5G runs a Snapdragon 8 Gen 1 modem and a 6.6-inch AMOLED panel simultaneously. Under that combined load, a cell with a degraded or uncalibrated discharge curve hits a voltage cliff faster than the fuel gauge IC predicts. The phone interprets the sudden voltage drop as a critical low and shuts down even though the reported percentage still shows 20–30%. One full slow discharge-charge cycle after replacement recalibrates the coulomb counter and resolves most premature shutdowns.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells shipped or stored for extended periods can self-discharge below 2.5V per cell, triggering a BMS lockout that prevents the phone from powering on or showing a charge indicator. Connect to a 5W or 10W charger — not a fast charger — and leave it for 20–30 minutes without attempting to power on. The charge IC will trickle current into the cell until voltage recovers above the BMS re-enable threshold, typically around 3.0V, at which point normal charging resumes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391848743002,"sku":"BWCS-SMS906SL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391848775770,"sku":"BWCS-SMS906SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391848808538,"sku":"BWCS-SMS906SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMS906SL-1.webp?v=1779142388","url":"https:\/\/batteryweb.com\/products\/samsung-galaxy-s22-plus-5g-replacement-battery-388v-4000mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
