Query: Battery is AWFUL and phone too complicated

I've had this phone for over a year and the battery life is awful. It has a very short battery life; it will go dead during a conversation even though the handset says it is fully charged. It is also too complicated and scrolls through the menu very slowly. Panasonic's customer service was poor. This phone is a waste of money.
