Virgin Mobile AWE Replacement Battery 3.7V 1400mAh

Up to 21% off
New arrival
From $16.99 USD $20.99
Shipping calculated at checkout.
Fits Virgin Mobile AWE and Awe N800 smartphones, replacing the OEM 3.7V lithium-ion battery.
This 3.7V 1400mAh cell delivers the voltage and capacity the AWE's power management IC expects for standard operation without voltage sag under display or modem load.
Connector type is proprietary to Virgin Mobile; battery seats flush in the battery compartment with a single locking tab that secures toward the device frame.
We bench-tested the cell across three full discharge-charge cycles; the BMS accepted the new pack on insertion with no fault codes or early cutoff signals.
On first use after installation, run one complete discharge-charge cycle with fast charging disabled — this lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging resumes.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

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

This is a 3.7V, 1400mAh Li-ion battery for the Virgin Mobile AWE and Awe N800 smartphones. It slots in where the original cell has degraded past usable capacity. Voltage and form factor match OEM spec at 59.40 × 46.00 × 5.10mm.

  • AWE and Awe N800 compatibility: Both models share the same battery bay dimensions, voltage rail, and connector pinout — one cell covers both. No adapter or modification needed.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on the AWE platform. The BMS accepted charging without fault flags, and cell voltage held stable under combined screen and modem load.
  • Fuel gauge recalibration after swap: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes into an uncalibrated state.

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

The AWE's fuel gauge IC retains the old cell's discharge curve in memory after a swap. The new cell hits a voltage cliff — where cell voltage drops sharply under modem or display load — at a different state of charge than the IC expects. The phone interprets this voltage drop as an immediate low-voltage cutoff and shuts down even though the percentage shown was still high. One full discharge-charge cycle recalibrates the coulomb counter to the new cell's actual curve, and the shutdowns stop.

Phone shows wrong battery percentage after replacement

The fuel gauge IC on the AWE uses a stored discharge profile to estimate remaining charge. When a new cell goes in, that stored profile no longer matches the new cell's chemistry state. The IC reads voltage correctly but converts it to a percentage using the wrong curve, so the number on screen drifts or jumps. Drain the battery until the phone shuts off on its own, then charge uninterrupted to 100% — this forces a full recalibration cycle and corrects the percentage readout.

Frequently Asked Questions

My AWE shuts off at around 25% after putting in the new battery — is the cell faulty?

The cell is not faulty. The AWE's fuel gauge IC is still using the discharge curve from the old battery, so it miscalculates where the voltage cliff sits on the new cell. Under modem or screen load, voltage drops faster than the IC predicts and the phone cuts out as a low-voltage protection measure. Run one full discharge to shutdown, then charge to 100% without interruption — the coulomb counter resets to the new cell's curve and the early shutdowns stop.

The battery percentage on my AWE jumps around erratically right after the swap — what's causing that?

The fuel gauge IC calibrates percentage against a stored discharge profile, and that profile was built around the old cell's impedance and voltage curve. A fresh cell has different characteristics, so the IC's estimates are inaccurate until it collects new data. Percentage jumps and sudden drops are normal for the first one or two cycles. Let the phone discharge naturally to shutdown once, then charge to full — the IC locks onto the new cell's curve and the readings stabilise.

The AWE won't power on at all after the replacement battery sat in the drawer for a few months — how do I recover it?

A Li-ion cell in storage self-discharges slowly, and if it drops below roughly 2.5V the BMS trips a lockout to prevent damage. The phone will not respond to the power button and may show nothing on screen. Connect the phone to a wall charger — not a PC port — and leave it for 20–30 minutes without pressing anything. The charge IC trickle-charges the cell back above the BMS recovery threshold, typically around 3.0V, at which point the BMS releases and the phone will power on normally.
