My N9's battery life has been great with 1.0.1 stable. With previous versions I would come back at the end of the the day with 20% to 30% battery. Now I come home with 50% to 60% battery. This is with moderate usage, inverted background on stock apps, 25% brightness with automatic brightness disabled. With light usage it can be around 70% or higher at the end of the day. Whatever traysh did with 1.0.1 stable for the battery should be implemented in other versions, if possible of course. Great work as usual.
