This would allow the user set the best balance between responsiveness and power consumption that suits its needs. Also, targeting a certain temperature would be a great feature to have. 3) Is there any plan to improve the current battery framework and provide information about the estimated recharging time, as it was before. I guess the versions before 2.6.24 used to provide this but the newer versions don't do it anymore.
