AFTER A FULL NITES CHARGE,

Question

AFTER A FULL NITES CHARGE, AND USING MY IPHONE FOR ABOUT8 MINUTES OF CALL IN A DAY, MY IPHONE BATTERY IS DOWN TO ABOUT 1/2 CHARGE, AND SOON IT WILL NOT LET ME CALL OR RECEIVE ANYMORE.

WOULD APPRECIATE ANY SUGGESTIONS AS TO HOW TO REMEDY THE PROBLEM.

APPLE PUBLISHES A LOT OF BS ON THE LASTING QUALITY OF THIS PHONE.
