N9 battery calibrate:
use your battery entirely empty. Charge the N9 battery to the full, when phone power switched off whole time. when it is 100% you can turn it on, but do not remove charger before it is fully booted!. ( If you did remove it.. battery cal did not work like it should ) Whola! Battery will last longer
