If the battery life on the phone is not what it once was then a common issue are running programs using too much energy to run. The two main culprits are the 3G and Bluetooth settings. Just by turning these off you will get another one to three hours per charge out of your battery. Make sure to go through your settings and make sure they are set to as many of the battery saving options as possible. If this does not work then I suggest testing your phone with a new battery. Your current battery may be nearing the end if its life. For directions on how to change your settings visit LG CU400 Troubleshooting.
