Maximum Power: Battery Utility

Your battery is talking, let MaximumPower translate.

MaximumPower lives in your menu bar and gives you instant access to the detailed power information macOS doesn't show you.
Know exactly what's happening inside your battery with the most up-to-date estimate math can provide.

See what matters at a glance
A color-coded battery icon shifts from green to orange to red as your charge drops, so you always know where you stand without opening a thing.
Time remaining or time to full (when charging) sits right next to it.
Click the menu bar icon to see charge cycles, battery temperature, health percentage, voltage, or last charged time.
