Sleep Monitor is a utility that tracks your Mac’s sleep and battery cycles. While several similar battery-tracking apps exist in the Mac App Store, few offer Sleep Monitor’s visual graph, which is the most important feature of the app.
One of the most interesting things I learned in testing Sleep Monitor is how quickly my MacBook battery recharges when my Mac is asleep. The app’s blue boxes indicate times when my Mac was asleep, and the white boxes indicate times when my Mac was awake. The green line represents a charging battery (or A/C power), and the orange line represents a de-charging battery. The chart provides a clear visual aid that shows how and when your Mac uses its battery. The steady gain and decline of the battery represents a healthy battery, and one that performs as it should (given my MacBook’s age).
If you’d just like to learn more your Mac’s battery cycles, Sleep Monitor is an interesting utility that sheds some light on a small, but critical, aspect of your Mac’s inner workings.
