Virgin Mobile AWE Compatible Battery 3.7V 1600mAh

Virgin Mobile AWE / Awe N800 — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1600mAh Li-ion replacement battery for the Virgin Mobile AWE and Awe N800 smartphones. It slots into the original battery compartment and connects to the same three-contact terminal as the factory cell. Capacity comes from product data — 1600mAh, 5.92Wh.

• AWE and Awe N800 compatibility: Both models share the same battery bay dimensions (59.40 × 46.00 × 5.10mm), the same 3.7V nominal rail, and the same three-contact BMS interface — so a single cell covers both variants without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a ZTE-platform device with equivalent BMS handshake requirements. The protection circuit responded correctly to charge termination and low-voltage cutoff events throughout testing.
• Fuel gauge recalibration on first use: On the first full cycle after installation, disable fast charging if the option is available. This allows the fuel gauge IC to build an accurate discharge curve against the new cell before high-current charging is applied to an uncalibrated state.

Sudden shutdown at 20–30% on the AWE after a cell swap

The AWE's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, the old curve still governs where the OS thinks the voltage floor is. At 20–30% indicated charge, the new cell's actual terminal voltage can drop below what the modem and display load require — the phone cuts out even though the gauge still shows charge remaining. One complete discharge-to-shutdown followed by a full uninterrupted charge resets the coulomb counter and maps the new cell's actual voltage curve. After that cycle, the percentage readings stabilise and the early shutoffs stop.

Phone warm near the battery bay during first charge after replacement

A new Li-ion cell typically has slightly higher internal impedance than a broken-in cell. During the first charge cycle, the charge IC pushes current into a cell with higher resistance, which generates more heat than normal at the battery bay. This is transient — impedance drops after the first few cycles as the cell's electrolyte settles. If the device feels warm to the touch but not hot, let the first charge complete without interruption and monitor the second cycle. If the bay stays hot to the touch beyond the first cycle, check that the battery connector is fully seated and making clean contact on all three terminals.
