Intex Cloud Tread Replacement Battery 3.8V 1500mAh BR22024BR

intex Cloud Tread — 3.8V Li-ion Replacement Battery (BR22024BR)

This is a 3.8V, 1500mAh Li-ion battery for the intex Cloud Tread smartphone. It replaces part number BR22024BR and fits directly into the Cloud Tread's battery bay. Voltage and capacity match the original specification: 3.8V nominal, 5.7Wh total.

• Cloud Tread platform fit: The Cloud Tread uses a fixed-form battery bay sized at 71.92 × 57.94 × 4.24mm. This cell matches those dimensions and the connector orientation used on the original BR22024BR. The BMS handshake on this phone expects a 3.8V nominal cell — a mismatch here causes the OS to reject the battery or report incorrect state-of-charge immediately after installation.
• Bench tested on actual hardware: We cycled this cell under a simulated Cloud Tread load profile — screen on, modem active, GPS polling. The BMS held voltage within the expected 3.4–4.2V window across the discharge curve. No spurious cutoffs were logged during the test.
• Fuel gauge recalibration on first use: On first installation, disable fast charging and run one complete discharge down to automatic shutdown, then charge to 100% uninterrupted. The Cloud Tread's fuel gauge IC reads the discharge curve to map the new cell — skip this step and the percentage readout will drift within the first few days of use.

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

This is a voltage cliff issue, not a capacity problem. The Cloud Tread's modem and display pull current spikes that cause a degraded or uncalibrated cell to sag below the BMS cutoff voltage before the fuel gauge reaches 0%. The phone cuts power to protect the cell. A new cell that hasn't completed one full calibration cycle will show the same behaviour because the coulomb counter is still using the old cell's discharge curve. Run one full discharge-to-shutdown cycle and the shutdowns stop.

Phone won't power on after the replacement battery sat in storage

If the BR22024BR cell self-discharged below approximately 2.5V during storage, the BMS enters lockout mode and the phone will not respond to a normal power button press. Plug in a charger and leave it connected for 15–20 minutes before attempting to power on — the charge IC needs to trickle current into the cell until it clears the BMS lockout threshold. If the screen remains black after that window, check that the charger is delivering at least 5V at the USB port before assuming a fault with the cell.
