Orange Stockholm Replacement Battery 3.7V 1100mAh Li-ion

Orange Stockholm / Gaga — 3.7V Li-ion Replacement Battery

This is a 3.7V, 1100mAh Li-ion cell that fits the Orange Stockholm and Orange Gaga handsets. Both phones share the same battery footprint and connector, so one part number covers both models. Capacity figures come from our product data — 4.07Wh total energy at rated voltage.

• Stockholm and Gaga compatibility: Both handsets run the same 3.7V battery rail and use an identical physical connector and cell footprint. Swapping between models is not required — this cell slots into either chassis without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Stockholm platform. The BMS accepted charge from the device's internal charge IC without flagging a fault, and current draw under screen and modem load stayed within expected limits throughout.
• Fuel gauge recalibration after install: On first use after fitting, disable fast charging if your network or charger supports it, then run one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map its reference points against the new cell's actual discharge curve before high-current charging begins.

Why the Stockholm reports wrong battery percentage after a cell swap

The fuel gauge IC in the Stockholm tracks charge state using a coulomb counter calibrated to the original cell's discharge curve. Fit a new cell and that reference no longer matches — the IC reads against old data. The phone may show 80% and shut down, or sit at 20% for far longer than expected. One full discharge from 100% to automatic shutdown, followed by an uninterrupted charge to 100%, resets the counter's endpoints and brings percentage reporting back into line.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff failure. Under combined modem and display load, the cell voltage drops sharply below the threshold the phone's hardware protection circuit will tolerate — typically around 3.2–3.4V — even though the fuel gauge still shows charge remaining. The old calibration curve does not predict that drop correctly on a new cell. Run the recalibration cycle described above, and if shutdowns continue, check that the battery contacts on the chassis are clean and making full contact, since high contact resistance amplifies voltage sag under load.
