From Taylor Marks:
Battery Status is a handy little app that lives on the right side of the menu bar and will tell you, for each supported wireless device connected to your computer,
- What percent of the battery life is remaining.
- When the last time you replaced the battery was.
- When the battery is estimated to die.
Also offers easy access to some information on the internal battery for laptops including:
- The battery's current percent.
- An estimate of how long the battery will take to fully charge (even if it's not plugged in.)
- An estimate of how long the battery can last (even if it's still plugged in.)
- The number of charge cycles on the battery.
- The percent of the design capacity that the battery is currently able to utilize.
Additionally, Battery Status has networking capabilities! With two simple checkboxes, "Broadcast" and "Receive", you can set up any number of Macs on your local home, school, or work network to share the statuses of their batteries with each other. Just check the handy "Recieved" menu in Battery Status to see how all the computers on your network are doing!
Supported wireless devices include Apple's wireless mice, trackpads, keyboards, and laptops. Additionally, Logitech's Performance MX mouse is supported. If you have another wireless device that you'd like supported, don't hesitate to contact me, the developer, and I'll look into adding support for it in a free update to Battery Status.
