I am wondering if they do really boost battery life... If so what are the best battery saver apps? I would like the one that has turn-off wifi when the screen is off option. :):):)
Do we really need battery saver apps for android ? I think even they take some battery juice for them to work right? Things like Battery Doctor and Due Battery saver only instruct us to close some apps to features like wifi gprs to save battery right?
If you are not rooted, they are useless right? Please correct me if I'm wrong :)
