Everyone with a laptop Mac needs to know a handful of tricks to help squeeze a few more computing minutes out of a MacBook battery. Some may decrease the screen brightness, others turn off Wi-Fi, but how do we know if these actions are truly helping matters? Information really does equal power and Battery Health 2.5 provides the battery information you need to get all you can from your Mac laptop.
Available for the low, low price of free from the Mac App Store, Battery Health can reside in either your dock or your menu bar and provide realtime specifics of the state of your MacBook’s internal battery.
There are many battery status apps, but Battery Health has an attractive, easy-to-use interface and some features not found in similar apps, including OS X’s built-in battery monitor software.
Battery Health shows your current charge in both its percentage of full and in its remaining milliampere hours (mAh). The app also shows how much of your battery’s original capacity remains (the 14-month-old 13in MacBook Pro that I’m using still has 97.4 percent of its original 5770 mAh capacity remaining.
Battery Health will estimate (as will Mountain Lion’s software) the amount of time your battery – at its present charge – will last doing what you’re currently doing. Battery Health goes further, though. When I write this review, Battery Health estimates that my MacBook Pro has five hours and 55 minutes of battery life left under current conditions. It also estimates the amount of time I have left under different usage scenarios, like browsing the web (five hours and 35 minutes), playing music (five hours and one minute), playing movies (two hours and 25 minutes) or just sitting in standby mode (30 hours and 22 minutes).
One of coolest features of Battery Health is the real-time power usage chart that’s available when running on battery power. You can see the watts or mAh being used currently and see how actions like closing applications, turning of Wi-Fi, or decreasing display brightness affect the amount of power your MacBook demands.
And if you could use a couple of more battery saving tricks in your arsenal, Battery Health also provides a handy list of 10 battery-saving tips, including instructions for calibrating your battery.
If you need the most out of your laptop’s battery, the more information you have about your computer’s energy demands and conditions, the better. Battery Health offers a wealth of such information, laid out in an attractive, unobtrusive style. And for free, this app is hard to beat.
