Capacity is 2250mAh (8.33Wh), matching the voltage rail these handsets require for calls, messaging, and application use. It fits the same battery bay without modification and uses OEM part numbers LIBR160 and 35H00082-00M.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eS710 and S730 shared battery platform:\u003c\/strong\u003e\n    Both handsets run the same 3.7V single-cell architecture with identical connector pinout and physical footprint — 54.03 × 39.60 × 11.37mm. The BMS in each phone communicates over the same two-wire interface, so one cell covers both models without any wiring change.\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 S710 platform and confirmed the BMS accepted the cell, reached full charge without thermal flags, and held voltage above 3.5V through high-screen-brightness operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first cycle after fitting this cell, disable any fast-charge mode and let the phone run through one complete discharge to cutoff, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell's discharge curve before it starts estimating state of charge under load.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the S710 reports the wrong battery percentage after a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe S710 uses a fuel gauge IC that builds a discharge model from the previous cell's impedance and capacity history. When a new cell goes in, that model no longer matches the actual cell chemistry. The phone reads a voltage level and maps it to the old curve, so it can show 60% when the cell is at 40% — or jump several percent in seconds under load. One full discharge-to-cutoff followed by an uninterrupted charge resets the coulomb counter and forces the IC to recalculate against the new cell.\u003c\/p\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 happens when the cell voltage drops sharply under a burst load — typically the modem transmitting or the screen at full brightness. A cell that reads 3.6V at rest can collapse below the BMS cutoff threshold the moment current draw spikes, triggering an immediate shutdown even though the percentage display still showed charge remaining. It is a voltage cliff, not a capacity problem. After the first full calibration cycle, the fuel gauge IC catches this earlier and the reported percentage at shutdown drops closer to 5–10%, which is the correct low-voltage cutoff point at around 3.4V under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405183975514,"sku":"BWCS-DS710XL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405184008282,"sku":"BWCS-DS710XL-2","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405184041050,"sku":"BWCS-DS710XL-3","price":33.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DS710XL-1.webp?v=1779370332","url":"https:\/\/batteryweb.com\/products\/htc-s710-replacement-battery-37v-2250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
