Battery life quickly drains: Samsung Galaxy S III

    Understanding the Issue



    • Battery drain
    • Battery life is very low


    What happens and why


    The battery life of the phone is significantly lower then expected. This can occur because of a conflict with the sync settings of an Exchange email account setup on the phone and the Exchange server settings.


    If the sync schedule during the Exchange account setup on the phone conflicts or differs  from the Exchange server settings, the Email app on the phone will override any existing schedules and will attempt to sync constantly. This drains the battery.
