This plugin displays a battery indicator in Obsidian's status bar.
A few visual aspects can be adjusted in the settings, like showing a textual percentage value and separating the battery level and charging indicator into separate icons.
The battery level thresholds for different icons will be customizable in a future update.
This plugin pairs great with the statusbar organizer plugin, in case you only want to show the battery indicator while in full-screen or if you want to change the indicator's position in the status bar.
