Fix Battery page animation

TextView summary1 has default height 2 line. If the content is longer
than 2 line, the TextView increases itself which causes the animation.
By increasing minLines to 3, it can avoid the animation. And remove
summary2 because it is only for debug purpose, the debug information
can be merged to summary1.
