54% means nothing.
Percentages don't help
54% could be two hours or four. Without knowing what time you actually die, you can't plan anything.
You toggle Low Power Mode too late
By the time you remember, you're already at 10%. An automated toggle at 40% would have saved you an hour.
Every app drains differently
Zoom eats battery. Safari doesn't. But macOS treats them the same. Your power settings should adapt to what you're running.

hey, i'm soren
(the guy who made turtlebar)
i never knew when my mac would die.
percentage means nothing. is that six hours? four hours? it depends on what you're doing. browsing lasts way longer than video editing.
so i built a menu bar app that shows the exact time, based on your actual usage. then i added smart power management: auto Low Power Mode, per-app rules, battery triggers.
one app. no bloat. know when you die, and stay alive longer.
