It carries a 2200mAh (8.36Wh) capacity and fits directly into the X3s battery bay. It replaces the original cell when the existing battery no longer holds a charge or has swollen beyond safe use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAmazing X3s compatibility:\u003c\/strong\u003e\n    The X3s uses a fixed 3.8V single-cell Li-ion architecture. The connector pinout and BMS handshake on this cell match that rail. No adapter or modification is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge on the Amazing X3s. The BMS communicated cleanly with the phone's charge IC, and the protection circuit tripped correctly at low-voltage cutoff without requiring a manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first install:\u003c\/strong\u003e\n    After fitting this cell, disable fast charging and run one complete discharge-charge cycle at standard rate. This gives the phone's fuel gauge IC time to map its coulomb counter against the new cell's actual discharge curve before high-current charging begins.\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\"\u003eA new cell that shuts the phone off at 20–30% reported charge is almost always a fuel gauge calibration issue, not a faulty battery. The coulomb counter in the phone was calibrated against the old cell's discharge curve. When the new cell's voltage drops under modem or screen load, the phone hits its cutoff threshold before the gauge catches up. Run one full discharge to 0% and a full charge to 100% without interruption. After that cycle the gauge re-anchors to the new cell and the shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone reports wrong battery percentage after cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Amazing X3s tracks charge state through a fuel gauge IC that builds a model of the cell over time. Swapping the cell breaks that model — the IC is still using data from the old battery. The percentage reading can jump, stall, or read 100% while the phone is actually close to cutoff. One full uninterrupted discharge-charge cycle forces the IC to rebuild its curve against the new cell. After that cycle, percentage readings stabilise at the correct value.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43392052854874,"sku":"BWCS-ZTA465SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43392052887642,"sku":"BWCS-ZTA465SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43392052920410,"sku":"BWCS-ZTA465SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZTA465SL-1.webp?v=1779143526","url":"https:\/\/batteryweb.com\/products\/twm-amazing-x3s-replacement-battery-38v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
