USCellular One Touch Premiere Compatible Battery 3.7V 1300mAh

USCellular One Touch Premiere — 3.7V Li-ion Replacement Battery (CAB31P0000C1)

This 3.7V Li-ion cell replaces the original battery in the Alcatel One Touch Premiere and ADR3035 smartphones sold under the USCellular brand. Capacity is 1300mAh (4.81Wh), matching the stock cell specification. It fits models listed under OEM part numbers CAB31P0000C1, CAB31P0001C1, and TB-4T0058200.

• One Touch Premiere and ADR3035 fit: Both variants share the same battery bay dimensions and connector pinout — 64.30 × 49.50 × 4.50mm with a matched voltage rail at 3.7V. The BMS handshake is identical across both model designations, so no firmware conflict occurs on boot.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the One Touch Premiere platform. The BMS responded correctly to charge termination, and the protection circuit tripped at the expected voltage floor without latching into lockout under normal discharge.
• Fuel gauge recalibration on first cycle: On first use after installation, disable fast charging and run one full discharge down to automatic cutoff, then charge to 100% uninterrupted. This gives the fuel gauge IC a clean reference curve against the new cell before it begins tracking coulombs accurately.

Why the One Touch Premiere reports wrong battery percentage after a cell swap

The phone's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches actual cell voltage behaviour. The gauge reads against the old curve and outputs percentage values that do not reflect real charge state. One full uninterrupted discharge-charge cycle resets the coulomb counter and lets the IC build a new curve against the replacement cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under load — typically when the modem fires at full power or the screen brightness peaks — even though the displayed percentage looks healthy. The fuel gauge reports 25% but the actual cell voltage has already fallen below the BMS cutoff threshold, around 3.0V under load, and the protection circuit trips. Run the recalibration cycle first. If shutdowns persist after one full discharge-charge cycle, check that the battery contacts in the bay are clean and making firm contact — a poor connection raises resistance and amplifies the voltage sag under modem draw.
