The system will power off when the battery level under threshold, prevents deep discharge, reduces stress on the cell, and helps maintain long-term battery health and lifespan.

lgtm @TuEmb do you think 10s is too frequent? https://github.com/BasedHardware/omi/pull/3452/files#diff-fc6983d86c90195a910760bb5c0ba59712e9aa2151b4c57c2aa430a13f58d463R393 previously, 60s, my concern is that it would consume more battery for reading the voltage and increase the instability. tell me more about your thoughts on the new implementation. |

@beastoin that's right, but I think the power consumption will not be too much. I will have an analyzation table on the power consumption task later to show how much we are using for each components |

as #2782 , the current battery percentage fluctuates too sharply, causing noticeable jumps up and down that may confuse users.
