Regarding some Devices Displaying Inaccurate Percentages
I'd like to thank the dozens of people who sent in system reports so that I could track down the cause of this issue.

I have identified the problem and am working on resolving it. No further system reports are necessary.

Thanks again,

Battery Status

I got my first wireless accessory for my iMac the Christmas of 2011, the magic trackpad. It's a great little device, except for the fact it eats batteries (and unlike the iPhone, you can't simply plug it in to the wall to recharge it.) Furthermore, it offers no indication of what its remaining battery life is.

Thus what prompted me to make Battery Status. Battery Status is a handy little app that lives on the right side of the menubar and tells you, for each supported device you have connected to your computer,
 - What percentage of the remaining battery is left.
 - When the last time the battery was replaced.
 - When the battery is expected to die next.

If you'd like more information regarding which devices are currently supported, please check the Device Support List. If you have another wireless device that you'd like supported, don't hesitate to contact me, the developer, and I'll look into adding support for it in a free update to Battery Status.

Also, if you use Battery Status, I'd really appreciate it if you'd leave a review on the Mac App Store for it.

Version 1.2 was submitted in mid May and approved in mid June. I can't remember what the actual changes or dates were. Version 1.3 is the current version, which was submitted in late June and approved on August 7th. I'll probably update this section of the website later this week... or come back to it next year and laugh about how long it's been since I updated.

Change Log for Version 1.1:
I've been stunned at how much email I've gotten regarding Battery Status. It's been on the store for only 10 days and I've received over a dozen emails on it (this is more than my other two apps on the store put together, and they've each been up for over half a year.) A lot of these emails contain requests for new features, and I'm happy to announce that I believe I have delivered on most, if not all, of the requested features, in version 1.1:
 - Support for internal batteries on the MacBook, MacBook Air, and MacBook Pro.
 - The ability to display remaining battery percentage alongside the icon in the menubar.
 - The ability to change the colors of the battery status icon to black and white, so it'll draw less attention to itself.
 - The ability to select a specific device to be reflected in the menubar.
 - The ability to run Battery Status on Snow Leopard (version 10.6.8.)
 - Quicker recognition of newly attached devices with batteries.

Version 1.11 was submitted to Apple on May 7th, 2012 and approved on May 16th.
 - Support for 32-bit machines.
 - Support for Mac OS X versions as old as 10.6.6.
 - A fix for the bug that could cause Battery Status to request a lot more RAM than it needs.
 - Even quicker recognition of newly attached devices with batteries.
 - Improved estimation techniques.

Version 1.2
 - Now sandboxed.
 - Now localized for German users.
 - Ability to share battery levels across a local Wi Fi network.
 - Ability to disable certain options (IE, for managed users.)
 - Added support for the Logitech Performance MX.
 - Added notification center support for Mountain Lion users.

I'm currently (as of February 2013) quite busy, but at some point I'd like to release Version 1.3 and have it include:
 - A window for configuring Battery Status to support other devices.
 - Retina quality graphics.
 - Less verbose logging in Console.

I'll also be localizing Battery Status into a few languages besides English and German. If you're interested in helping with translating to any language, email me at, and I'll send you the files that need to be translated.
