I'm developing something like a stopwatch, so I have to turn off that below 20% battery alert view somehow during a time measuring session (I will inform the user about battery percentage elsehow).
I just couldn't google for any answer.
Whoa.Then what is the best way to ask for the battery percentage?UIDevice class? Is the system alert launched on an actual 20% (Maybe I can inform the user on 30% before starting a time measuring session)?

To get the battery life, you can use `[[UIDevice currentDevice] batteryLevel]`, which will give you a float between 0.0 and 1.0. http://stackoverflow.com/questions/1469549/iphone-calculating-battery-life explains how to get notifications about battery life.
