ive found in the short time that ive had my transformer that its eating battery life fairly quickly. so does anyone have any tips for conserving battery life that im unaware of? i know the standard ones like reduce brightness to a 1/3rd or less, turn off wifi etc. etc. but maybe there are some more in honeycomb over and above the standard ipad ones i dont know about. eg. gps, does it eat battery? turning it off would net me hours more time, or nothing at all really?
