The disadvantage of this iPhone 3G is it has really limited battery lifetime. For Normal usage, it can only resist in approximately one and half day.

We can decrease the level of screen brightness, because more brightness can consume more power. We can also disable push email feature, 3G and Wifi. Use 3G and WiFi only if we will make internet connection. Last but not least, always charged the battery whenever we have a chance. Hopefully these tips are useful.
