Perform a Prolonged Trickle Charge Recovery

This procedure is designed to recover a battery that has fallen below its safety voltage threshold due to long-term inactivity.

1. Connect the official Huawei charging cradle to a standard 5V/1A power adapter. Avoid using high-speed chargers or computer USB ports, as these may not provide the necessary power handshake for a deeply discharged device.
2. Place the Huawei Watch 2 onto the charging cradle, ensuring the pins are aligned correctly.
3. Leave the watch on the charger undisturbed for a minimum of 2 to 4 hours. Do not disconnect or repeatedly remove the watch during this time, as this will interrupt the trickle-charging process.
4. Once the recovery period has elapsed, press and hold the power button for 10–15 seconds while the watch remains on the charger to trigger a forced reboot.
5. Verify the fix by observing if the watch proceeds to boot or displays a standard charging indicator rather than the "X" mark.
