looking at all the power saving apps including Juice defender pro and reading up and down the net i came accross
an app called "permission manager pro".
This app actually allows you to set permissions for each app you have installed.
So you can define what the app is allowed to use say use location, read yor contacts and so on.
Anyway i was playing with it adjusting all kind of rights and realized after everything was set up and the phone was restarted that my phone uses less power than before.
I still have to test it more but i am sure this app is saving the battery quite a bit.
