You can check the bugtracker for potential fixes. Improving batterylife by 10% isn't really something to fix, since it is very application dependant. Also I doubt mms will make it in the next release because of it's complexity. Noise issue with images cannot be fixed without altering image quality. Noise is a feature of the sensor in the camera, you can diminsh it with certain software algorithms but that almost always results in a loss of detail as well.
