Show the Remaining Battery Time Indicator Again in OS X Mountain Lion
OS X Mountain Lion changed the battery indicator for mobile Mac users, removing the option to show the remaining battery life time and instead displaying only a percentage, like iOS. For those of us who live on the go and rely heavily on battery life, knowing the actual remaining battery capacity in hours is much more meaningful than a percentage.
Rather than clicking on the battery icon every time you want to know how much time you have left before needing to plug in, download a great free (beta was free only) third party tool, appropriately called BatteryTimeApp:
BatteryTimeApp is ridiculously simple and works with both OS X Mountain Lion and OS X Lion for MacBook Air, MacBook Pro, or MacBook. It’s currently in beta and offers no frills, which is perfect if all you want is to see the estimated time remaining of your portable Mac before you need to connect to a power source again.
Hopefully a future update to OS X 10.8 will bring back the indicator natively and little third party tools won’t be necessary, but until then grab it while it’s free.
Update: The app beta was free but now the developer has uploaded it to the App Store and is selling it for $1. For a similar free solution, you can download SlimBatteryMonitor.
Update 2: Another great free option also pushes battery time remaining notifications to OS X Notification Center, check it out.
