Batteries Not Save Electricity

We see from the durability (life time) and standby time and talk time, we can examine and test the phone by using the power supply with the following steps :

    * When your phone is turned off (off) this is the mobile phone has taken the current in the battery, this is proven by needle amperes at power supply shows the number 100 milli amperes. Things like this that causes the cell phone battery wasteful, because the cell phone constantly taking the current from the battery even though the phone was dead.
    * Now remove the IC PA first.
    * Do re-test such as the above, see the needle ampere if silent, then certainly the PA IC is faulty.
    * Replace the PA with a new IC, do re-test such as the above, see the needle ampere, ampere needle should remain silent.
    * Battery you are not wasteful anymore.
