It matches OEM part numbers AB1050CWMC and AB1050FWMX. The cell fits the same 53.18 x 34.00 x 6.80mm cavity and uses the same connector orientation as the factory unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXenium X116, X125, X126, and 128 compatibility:\u003c\/strong\u003e\n    These four models share the same battery bay dimensions, 3.7V single-cell architecture, and connector pinout — which is why one cell covers all four. The BMS handshake protocol is identical across the range.\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 Xenium platform. The BMS accepted the cell without triggering a protection cutoff, and the charge IC reached termination voltage cleanly at 4.2V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to auto-off followed by a full uninterrupted charge before using the phone normally. The Xenium's fuel gauge IC was calibrated to the old cell's discharge curve — skipping this step causes the percentage readout to drift immediately after installation.\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 after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the fuel gauge IC still holds the discharge curve of the old, degraded cell. When the new cell hits the voltage cliff under modem or screen load — typically around 3.6V — the phone cuts power before the reported percentage reaches zero. The gauge hasn't learned where the new cell's usable capacity actually ends. One full discharge-charge cycle forces the coulomb counter to reset its reference points against the new cell, and the premature shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone won't power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this cell dropped below approximately 2.5V per cell, the BMS enters lockout mode and blocks current flow to protect against unsafe charging of a deeply discharged cell. Plug the phone into a charger and leave it connected for 15–20 minutes without attempting to power it on — the charge IC trickle-charges the cell back above the BMS re-enable threshold. Once voltage recovers above 3.0V, the BMS unlocks and the phone starts normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392091422810,"sku":"BWCS-PHX128SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392091455578,"sku":"BWCS-PHX128SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392091488346,"sku":"BWCS-PHX128SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHX128SL-1.webp?v=1779143708","url":"https:\/\/batteryweb.com\/products\/philips-xenium-x116-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
