The original cell degrades with charge cycles, causing capacity fade and unexpected shutdowns. This replacement restores the phone to factory power specs.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXenium S327 and CTS327 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay dimensions, 3.8V nominal voltage rail, and AB3000KWMT part number. The connector pinout and BMS handshake are identical across both variants, so one cell covers either device.\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 the S327 platform. The BMS negotiated the charge protocol correctly, protection cutoffs triggered at the expected voltage thresholds, and the fuel gauge IC accepted the cell without flagging errors.\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 and let the phone complete one full discharge-to-charge cycle at standard current. This gives the fuel gauge IC a clean discharge curve from the new cell before high-current charging begins on 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  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff issue, not a capacity problem. Under modem transmission or screen peak loads, the new cell's voltage drops sharply at around 3.5V, dipping below the threshold the fuel gauge IC expects for 20–30% remaining. The phone interprets this as a dangerously low state and forces a shutdown to protect the cell. One full calibration cycle — discharge to 1–2% without interruption, then charge uninterrupted to 100% — resets the coulomb counter and pulls this cutoff point back to its correct voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eUSB-PD or fast charge not accepted on the first cycle after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome Xenium S327 units will only negotiate fast charge once the charge IC has seen a baseline charge session on the new cell. On the first cycle, the IC defaults to standard 5V\/1A input while it validates the new BMS. This is not a fault with the replacement cell. Connect the phone to the original charger, complete one standard charge to 100%, disconnect, then reconnect — fast charge negotiation typically resumes from the second cycle onward.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43391885344858,"sku":"BWCS-PHS327SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43391885377626,"sku":"BWCS-PHS327SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43391885410394,"sku":"BWCS-PHS327SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHS327SL-1.webp?v=1779142560","url":"https:\/\/batteryweb.com\/products\/philips-xenium-s327-replacement-battery-38v-2800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
