Battery Usage

By Petur Ingi Egilsson

Open the Mac App Store to buy and download apps.


Have you ever wondered at which speed your laptop is draining the battery?

Battery Usage is small app which resides in your taskbar and displays the battery consumption in milliampere hours (mAh). It is exactly this reading, which Apple uses in order to determine how long time till your battery is depleted.

The battery usage is fetched from the battery every 30 seconds, and shows the average consumption during the last 30 seconds.

Battery Usage is a wonderful little app that just works!

Battery Usage is a wonderful little app that just works!. MacBook Pro with the quad i7 uses 2 graphic processors. This little app tells you battery usage consumed in the previous 30 seconds so that use can troubleshoot and the monitor battery usage. See what Apps use up battery power at a glance. And the Developer responds very quickly to emailed questions.

Akways reads 0mAh, not matter what

Macbook Air i7. Plugged in or not, this always read 0mAh, so I not sure what this means. If the description is right, then this means no battery is being used and my laptop will remain charged forever. Pretty nice. Actually I just think this is broken.
