Backlight On is a free backlight control app by Ostwald Designs that lets you choose which apps have no backlight timeout causing your BlackBerry to go dark with no input. Sort of similar to how the BlackBerry OS already treats the first-party video player: the backlight will stay on until the video is over.
I find this app particularly handy because I like saving battery by keeping my backlight timeout time to a low. This app allows me to have one of the more battery-efficient backlight timeout times that I can handle, while still having a couple of specific apps whitelisted that don’t require a lot of user input while running.
The couple of apps that I chose to keep constantly lit are Texas Hold ‘em King LIVE and Google Maps. Those are my apps that with a 15 second timeout go dark multiple times per session. I can see this app being ideal for car-mounted BlackBerry setups too.
