It also cross-references OEM numbers 35H00187-00M, 35H00187-01M, and PJ83100. Dimensions are 61.40 × 54.10 × 4.30mm — confirm against your original cell before fitting.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOne X platform compatibility:\u003c\/strong\u003e\n    The One X, One XT, Supreme, and Endeavor share the same battery bay geometry, connector pinout, and charge IC handshake. All run on the same 3.8V nominal rail, so one cell covers the full model group 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 a full charge cycle on an HTC One X unit. The charge IC accepted the BMS handshake on the first connection, reached 4.35V at full charge, and the protection circuit tripped correctly at the low-voltage cutoff during a controlled discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On first installation, disable fast charging and run one complete discharge-charge cycle from 100% down to automatic shutdown and back to full. This gives the fuel gauge IC a clean reference curve for the new cell before high-current charging is applied to an uncalibrated pack.\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 HTC One X after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe One X uses a coulomb-counter fuel gauge IC that was calibrated to the discharge curve of the original aged cell. A fresh cell has a steeper voltage drop near the end of discharge, which the old calibration data does not match. The phone interprets the voltage cliff as a critical low-battery event and shuts down before the reported percentage reaches zero. One full discharge-charge cycle resets the coulomb counter and aligns the gauge to the new cell's actual curve. After that cycle, percentage readings stabilise and early shutdowns stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePhone stays at 0% and will not power on after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-Polymer cells stored at or near full discharge can drop below 2.5V per cell, triggering the BMS protection circuit into lockout mode. In lockout, the battery appears completely dead — no charge indicator, no boot. Connect the phone to a wall adapter rated at 5V\/1A and leave it for 20–30 minutes without pressing the power button. The charge IC trickle-feeds current into the cell until the BMS exits lockout, typically around 2.9V, after which normal charging resumes and the phone will power on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405006569562,"sku":"BWCS-HTS720SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405006602330,"sku":"BWCS-HTS720SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405006635098,"sku":"BWCS-HTS720SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTS720SL-1.webp?v=1779369806","url":"https:\/\/batteryweb.com\/products\/htc-one-x-replacement-battery-38v-1800mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
