Disable Auto power off

Please have any method to disable the power saver for the phone. (Always on)
The another question is how can make the App running in background (ie: When the browser not in front, but the timer inside the App is still counting)
Sorry for my poor English !

Generally, manufacturers will not allow web apps to take control of a phone that way. You can imagine the trouble which a web page could cause if it was allowed to do this.

Using PhoneGap, you can make an AppStudio app which runs in the background.

Thanks for your kindly reply.
Since I’m a novice for mobile programming, I just know Basic (Visual Basic) programming before.
For the case, I need to starting learn more about PhoneGap on NSB AppStudio
