Description

Verification
  • I searched for similar bug reports and found none was relevant.
What happened?

Battery drains to 0% and the watch doesn't appear to "shut down" to prevent high depth of discharge that is detremental to the health of the battery.

What should happen instead?

A common behavior from electronic devices is to gracefully power off when the device reaches 0%

Reproduction steps

Discharge the battery almost all the way until the indicator reads 0% and the watch continues to work until the battery is unable to supply enough voltage and the watch dies.
This is generally a bad thing for long term battery health:

More details?

This might not be as big of a problem as it seems, and may have already been compensated for on a hardware level (or on a software level that I do not know about as of yet), but it still seems like a better idea to gracefully turn the watch off when the battery hits 0% to prevent further discharge and degradation to the battery.

Research direction

No source file, test, or entry point is identified in the issue. Reproduce the behavior on the stated v1.10.0 firmware, then trace how battery depletion and power-off are handled and confirm that any change prevents continued discharge without disrupting normal low-battery behavior.
