HT1476: iPhone and iPod touch: Charging the batteryLearn about iPhone and iPod touch: Charging the battery

I have found a solution for my iPhone battery life: recharge the battery until reach 80 to 85%. Make a full recharge just once a month (IOS 6 User's Guide). It takes few days to see the improvements.
Now my battery life is over 15 hors with a single charge.
Hope it will be helpful
