It fits the original battery bay directly, using the same OEM part number EB504465VU. Swap it in when the original cell can no longer hold a usable charge through a normal day of calls, messaging, and media.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ei8910 Omnia HD compatibility:\u003c\/strong\u003e\n    The Omnia HD uses a single-cell 3.7V Li-ion architecture with a specific connector pinout tied to the phone's charge IC. This cell matches that voltage rail and connector layout, so the phone's charge controller and protection circuit communicate with it correctly from the first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the bench, monitoring BMS cutoff thresholds at both the low-voltage floor and the charge termination point. The protection circuit responded correctly at both limits — no premature cutoff, no overcharge condition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    On the first cycle after installation, run the phone down to automatic shutdown, then charge it uninterrupted to 100% before normal use. The i8910's fuel gauge IC needs one complete discharge-charge pass against the new cell's actual discharge curve to report accurate percentages.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the Omnia HD reports wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe i8910 uses a coulomb counter that builds its charge model from the cell it was last calibrated against — the original, aged cell. Drop in a fresh 2400mAh cell and the phone's fuel gauge IC is still reading against the old degraded curve. This causes the percentage display to jump, stall, or cut to shutdown well before the cell is actually empty. One full discharge-to-shutdown followed by an uninterrupted charge to 100% resets the coulomb counter against the new cell's actual capacity.\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 usually means the cell voltage is dropping below the phone's minimum load threshold under the combined draw of the modem radio and display — even though the percentage readout says charge remains. A fresh cell will show this until the fuel gauge recalibrates, because the IC is predicting voltage collapse based on the old cell's internal resistance profile, not the new one. Run one complete discharge cycle down to automatic shutdown and let the phone restart. After that cycle, the shutdowns at 20–30% should stop as the fuel gauge maps the new cell's voltage curve under load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405138657370,"sku":"BWCS-SMI8910XL-1","price":27.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43405138690138,"sku":"BWCS-SMI8910XL-2","price":31.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43405138722906,"sku":"BWCS-SMI8910XL-3","price":34.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI8910XL-1.webp?v=1779370278","url":"https:\/\/batteryweb.com\/products\/samsung-i8910-omnia-hd-replacement-battery-37v-2400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
