Homebrew developer pspflashsystem's prxutility has proven itself to be quite useful for those who are quite mindful of their PSP's battery juice. The recently updated application is once again revised, with some helpful additions: a more accessible Help menu, and a new menu that gives more info about your PSP's battery.

Check out the changelog below (as translated from French by our trusty weblator) for more details about the changes:

* The Help menu is now accessible by pressing L + NOTE simultaneously and left alone. After a while...
* You can now access a new menu that tells you about your battery (such as level of charge and hours remaining before unloading your batter, the temperature of your battery, the voltage of your battery, battery status, it also tells you if your battery is present or not and if the AC adapter is connected to the PSP or not). This menu is accessed by pressing buttons simultaneously VOLUP NOTE +
* Corrections of a few minor bugs
* Best legibility of menus

As always, you need to go through the readme file first to get more information about how to install this application. But since its written in French, you may need to run it through a translator. Enjoy!
