An application to count battery usage.
Application will start count whenever power cable was disconnected from notebook, and will reset the count whenever the power is connected.
Application will ignore the count during sleeping, or powered off, but still record these activities for reference.
The last result depend on the how heavy the system using CPU, hard disk, screen brightness, etc. or the ages of battery itself.
***** Trysta1217: This app performs a function I have been wishing for for ages. Instead of trying to keep track of exactly how long your battery actually lasts this app does it all for you perfectly. I got the new 2013 MBA and I wanted to see how close I was getting to Apple's quoted battery estimates. With the help of Battery Logger I now always know exactly how long I've been on battery (without sleep times being included but you can see that too). I also really appreciate that it saves old stats so I'll be able to see how well my battery life holds up over the lifetime of this computer. (If anyone is wondering so far Battery Logger shows the 2013 MBA battery is fantastic) Thanks to the developer for providing this! It is basically perfect as far as I can tell.
***** i_Aamir: If your trying to find out your Mac's exact battery usage, just like on the iPhone and iPad this is the one and only app that will do it perfectly! I've been using since I got my MBP-R and it’s been great in showing me how long my battery actually lasts! Would definitely recommend to everyone!

Exactly what I was looking for - This great app will give you the definitive answer to the question "How long will my MacBook run on the battery?" I've been using it for the past few days and have discovered that my late 2010 MacBook Pro 15" can run for 6 hours with an accumulated sleep time of 13 hours. It will also keep a log for each charge/run cycle. I highly recommend this app.
Terrible! Fails to open after closing - This app is terrible. Fails to open after closing the app. Trying to reopen after initial launch and nothing happens.

Great app. Doesn’t use estimates — gives me actual battery life - I love that I don’t have to plan a day to test my battery life by keeping my MacBook Pro open from the time the battery is at 100% until it reaches 0%. Instead, with Battery Logger, I just use my MacBook Pro like I normally would and it keeps track of when it is sleeping and when it is awake and using the battery. Sleeping does use a small amount of battery. It also keeps track of charging time and has a battery timeline which shows charges and discharges. Very helpful, thank you.
Really like this useful app - I've got a couple of other battery apps. This fits in nicely - it's nice to have a timer without having to remember to stop and start a timer. Has already told me my MBP sleeps more than I thought! Am using it with the new MBP 2016 to look at battery performance. Only thing I'd like is an expandable window - sometimes the times in the sleep and off sections are truncated.
