It also fits the Omnia 3G, Omnia Pro, and Giorgio Armani variants that share the same battery bay and connector spec. Voltage and physical dimensions match OEM: 64.60 × 43.90 × 5.20mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOmnia HD and cross-compatible variants:\u003c\/strong\u003e\n    The i8910, Omnia 3G, Omnia Pro, and Giorgio Armani models all draw from the same 3.7V rail and use the same physical connector. One cell covers the full range because Samsung kept the battery bay unchanged across these variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the i8910. The BMS handed off cleanly to the phone's charge IC at 4.2V, and the protection circuit tripped correctly at the low-voltage cutoff without requiring manual reset.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge recalibration on first use:\u003c\/strong\u003e\n    Disable fast charging for the first complete discharge-charge cycle after fitting this cell. The i8910's fuel gauge IC calibrates against the cell's discharge curve on that first cycle — skipping this step locks the coulomb counter to stale data from the old cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the i8910 Omnia HD reports the wrong battery percentage after a cell swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe i8910 uses a fuel gauge IC that tracks charge state by measuring current in and out over time. When you fit a new cell, the IC still references the discharge curve it mapped to the old, degraded cell. The percentage readout will appear inflated or will jump unexpectedly until the IC remaps itself. Run one full discharge down to automatic shutdown, then charge uninterrupted to 100% — this forces the coulomb counter to rewrite its reference curve against the new cell's actual capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSudden shutdown at 20–30% remaining on the Omnia HD\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage drops sharply under load — the AMOLED display and HSPA modem together pull enough current to cause a rapid voltage sag even when the gauge still shows charge remaining. The BMS reads the sag as a fault condition and cuts output before the percentage reaches zero. If this occurs on a new cell, the fuel gauge IC has not yet completed recalibration. Run one full cycle as described above; if shutdowns continue past that point, confirm the battery contacts on the phone body are clean and making full contact — oxidised contacts increase resistance and worsen voltage sag under the same load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43405140754522,"sku":"BWCS-SMI8910SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43405140787290,"sku":"BWCS-SMI8910SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43405140820058,"sku":"BWCS-SMI8910SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMI8910SL-1.webp?v=1779370279","url":"https:\/\/batteryweb.com\/products\/samsung-i8910-omnia-hd-replacement-battery-37v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
