Samsung Bada App: BatteryLife
What this application does, is to permanently calculate how much battery you have considering what are you doing with your phone. For example it shows you how much battery you have if you record, or if you play games. It even shows you how much talking time you have left before the phone shuts down.
The application has only 0.85 MB and is only for Bada based phones. It is a bilingual application, so that means it can be in English or Chinese.There is a new version out BatteryLife 1.1 which comes with a new camera time and a new video time.
I would definitely recommend the BatteryLife application for Bada, because it is super useful.
