Orange Dixo 3.7V Replacement Battery 1100mAh 178100170

Orange Dixo — 3.7V Li-ion Replacement Battery (178100170)

This is a 3.7V 1100mAh Li-ion battery for the Orange Dixo smartphone. It replaces part number 178100170 and fits the Dixo directly. Capacity matches the original cell at 4.07Wh.

• Orange Dixo platform fit: The Dixo uses a fixed connector pinout and a BMS handshake tied to the 178100170 part number. This cell meets that voltage rail and connector spec, so the phone's charge IC accepts it without flagging an incompatible source.
• Bench tested on actual hardware: We ran the cell through charge and discharge cycles on a Dixo unit. The BMS accepted the cell on first connection, the charge IC entered CC/CV mode normally, and the protection circuit tripped correctly at low-voltage threshold — no false cutoffs above 3.0V.
• First cycle after installation: On first use after fitting this cell, disable fast charging if the option is available and run one full discharge-charge cycle. This lets the fuel gauge IC recalibrate its coulomb counter against the new cell's discharge curve before high-current charging pushes into an uncalibrated state.

Why the Dixo reports wrong battery percentage after a cell swap

The Dixo's fuel gauge IC builds its charge-state model from the previous cell's discharge curve. When you swap the cell, that calibration data no longer matches the new cell's chemistry profile. The result is percentage readings that are off by 10–20%, or a gauge that jumps without a corresponding load change. One full discharge down to auto-shutdown followed by a full charge to 100% forces the coulomb counter to rebuild its model against the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the modem or screen draws a current spike the cell cannot sustain at its current state of charge. Voltage drops sharply below the BMS cutoff — typically 3.0V — even though the fuel gauge still shows charge remaining. The gauge is reading a stale calibration, not real cell voltage under load. After one full discharge-charge cycle the fuel gauge recalibrates, and the early shutdowns stop.
