It replaces OEM parts AB2300AWML and AB2300AWMT. Fit this cell when the original no longer holds charge, causes unexpected shutdowns, or fails to power the phone at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXenium S396 fitment:\u003c\/strong\u003e\n    The S396 uses a removable battery bay with a fixed connector pinout tied to the AB2300 cell profile. Both OEM part numbers reference the same voltage rail and connector spec, so this replacement slots into either production variant without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the S396 platform. The BMS accepted charge from the phone's charge IC without error flags, and the protection circuit responded correctly to end-of-discharge cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration after swap:\u003c\/strong\u003e\n    On first use after installation, disable fast charging and run one full discharge-to-charge cycle. This gives the phone's fuel gauge IC time to map the new cell's discharge curve before high-current charging begins on an uncalibrated reference.\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 Xenium S396\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage cliff problem, not a capacity problem. Under high-load conditions — active LTE, screen at full brightness, or simultaneous app processing — the cell voltage drops faster than the fuel gauge IC predicts from its stored curve. When the cell voltage sags below the shutdown threshold, the phone cuts power even though the gauge still shows charge remaining. A full discharge-to-charge cycle after fitting the new cell lets the coulomb counter recalibrate its voltage-to-capacity curve. After one complete cycle, the reported percentage tracks actual cell voltage much more accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping erratically after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eErratic percentage readings on the first day after a cell swap are caused by the fuel gauge IC referencing its old calibration data against the new cell's discharge profile. The two curves do not match, so the reported figure jumps as the IC loses tracking. This is not a faulty battery. Fully discharge the phone until it shuts off automatically, then charge uninterrupted to 100% — the IC resets its reference during this cycle. After that first full cycle, percentage readings should stabilise within ±3%.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392034242650,"sku":"BWCS-PHS396SL-1","price":26.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43392034275418,"sku":"BWCS-PHS396SL-2","price":30.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43392034308186,"sku":"BWCS-PHS396SL-3","price":33.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHS396SL-1.webp?v=1779143087","url":"https:\/\/batteryweb.com\/products\/philips-xenium-s396-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
