Verizon Omnia i910 Compatible Battery 3.7V 1200mAh

Verizon Omnia i910 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1200mAh Li-ion replacement battery for the Verizon Omnia i910 Windows Mobile smartphone. It fits the original battery slot directly and restores power to the display, processor, and cellular radio. Capacity is 1200mAh (4.44Wh), matching the factory specification.

• Omnia i910 platform fit: The i910 uses a fixed 3.7V single-cell Li-ion format with a three-contact terminal — positive, negative, and thermistor. Any replacement must match that contact layout exactly or the charge IC will reject the cell.
• Bench tested on actual hardware: We ran this cell through the i910's charge IC at 500mA. The BMS handshake completed on the first cycle, charge termination triggered at 4.19V, and the thermistor line read correctly throughout — no fault codes on the PMIC.
• Fuel gauge recalibration on first install: After fitting this cell, run one complete discharge down to auto-shutoff before recharging. The i910's fuel gauge IC carries its learned curve from the old cell — without a full discharge cycle, it will report inaccurate percentages until it maps the new cell's voltage profile.

Sudden shutdown at 20–30% on the Omnia i910

The i910's cellular radio and display draw simultaneous current spikes that a degraded cell cannot sustain. When internal resistance climbs, terminal voltage drops sharply under load — even if the resting voltage reads mid-range. The fuel gauge IC reads resting voltage, not load voltage, so the phone shows 25% and then cuts out immediately. A fresh 1200mAh cell with low internal resistance holds terminal voltage above the PMIC's 3.2V cutoff threshold through those combined load events.

Phone warm near the battery slot during the first few charge cycles

A new cell starts with slightly higher impedance than a broken-in one, so the charge IC dissipates more energy as heat during the constant-current phase. This is normal for the first two to three cycles on the i910 and fades as the cell's impedance settles. If the phone stays warm beyond cycle three, check that the back cover is seated flush — any gap restricts thermal dissipation from the back panel. Warmth should not exceed what you can hold comfortably; anything hotter than that points to a seating or contact issue.
