In the recent OS 7.1 leak for the BlackBerry Bold 9790, a new feature was discovered. We all heard that the battery life on RIM’s new lineup just doesn’t stack up with previous handhelds so the BlackBerry maker is probably listening. The new feature discovered in OS is called ‘Battery Save Mode’.

The new feature allows a user to set a battery save mode once you hit low battery life. Thereby, extending the use of your device. Bold 9790 users who are running the leaked OS, sound off on the comments and let us know how this is working for you.
