Sharp Aquos V7 Plus TLp049FA Compatible Battery 3.87V 4900mAh

Sharp Aquos V7 Plus / SH-C06 — 3.87V Li-Polymer Replacement Battery (TLp049FA)

This is a 3.87V, 4900mAh lithium-polymer replacement battery for the Sharp Aquos V7 Plus and SH-C06 smartphones. It uses OEM part number TLp049FA and matches the original cell's dimensions at 92.00 × 65.00 × 3.50mm. Swap it in when the original cell can no longer hold a charge or causes unexpected shutdowns.

• Aquos V7 Plus and SH-C06 compatibility: Both models share the same battery bay geometry, connector pinout, and BMS handshake protocol — one cell fits both without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge passes on compatible hardware. The BMS responded correctly to charge termination signals and held voltage within spec under sustained screen and modem load.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes into an uncalibrated state.

Why the Aquos V7 Plus reports wrong battery percentage after a cell swap

The Sharp Aquos V7 Plus uses a coulomb-counter-based fuel gauge IC that builds its discharge model from the original cell's capacity curve. When you install a new cell, that stored model no longer matches the actual cell chemistry. The IC keeps reporting percentages against the old curve until it completes at least one full, uninterrupted discharge-charge cycle. Run the phone down to automatic shutdown, then charge to 100% without interruption — after that cycle, percentage readings stabilise.

Sudden shutdown at 20–30% remaining on the replacement cell

This is a voltage cliff issue, not a capacity defect. Under combined modem and display load, cell voltage drops faster than the fuel gauge IC predicts, hitting the BMS undervoltage cutoff while the screen still shows 20–30%. It happens most often in the first two cycles before the fuel gauge recalibrates. Run one full discharge-charge cycle with fast charging off — once the IC maps the new cell's voltage curve, the cutoff aligns to the correct percentage. If shutdowns continue past cycle three, check that resting voltage after a full charge reads at or above 4.35V.
