Has something changed with the 9.40 that affects battery life. I feel mine is draining extremely fast. It was at 67% yesterday and today is 44%. I only road for an hour. I have auto brightness off and backlight set to off. Not sure what is going on.
Downgraded to 9.29 since that was the last version I had manually installed. Had to reset all my settings but there is no current drain on the unit anymore. Will keep an eye on it.
