Just a few days ago, homebrew developer placo23 released a very useful application, BatteryInfo, that lets PSP users check in on the battery status of their handhelds more effectively and accurately. Well, BatteryInfo is already updated (that was fast!), with some fixes that further enhances the user experience for this handy application. Here's the changelog for your perusal:

CHANGELOG:

- Updated the font and background, now it looks like the default PSP XMB font
- Fixed the bug when the PSP has no battery to display a message instead of a huge negative number
- More compatibility with other applications
- Uses less memory resources

You can download the application from the link below, and more information can be found in the Readme link. Enjoy!
