Well guys I am one of these people who is very concerned about the battery life of all my devices (I carry an extra battery for all of it) I am an outgoing person which means I could be ages away from a plug when I need one. Any way since the battery is not changeable on the N9 I tried to find ways to save it by lowering the Idle consumption.

so far the best I could reach is 3ma after a restart and recharge which allows me to about 5 to 6 days of extremely light usage (power saver mood, and 2G only, and light phone usage)

however with heavy usage I get about 2 days out of it. (about 6 hours of navigation, about 3 hours of internet on wireless, about 2 hours of calls, a number of sms and some gaming as well *power saver mood is on!)

so was any one able to get better results?
is there a way to reduce the active consumption which is 100 to 300ma average under that kind of usage?
what is your own battery usage statistics?
