    On every forums ppl are complaining about battery life, but their results of battery life aren't compareable at all.

    Claiming that a battery lasts more than 9 hours without telling us how you used the phone is pretty useless.
    So I tryed to figure out a testing condition that fits most ppls usage.

    The best way of comparing the iPhone battery is playing a video, because a vid does not rely on user input.

    So my suggestions for a testing condition that should work fine are:

    * 3G should be off because of different signal strength.
    * location services should be off because of different signal strength.
    * Wifi should be off because of same reasons
    * push should be off
    * runtime: 8 hours ( it is very important not to play too few hours because different battery calibration; I found out in other forums that ppl who did the same test had different usage time at 80% but the same at 30% which is a result of different battery calibration )
    * the vid should be the same
    ( no, I'm not a fan but it is the longest vid podcast I have found )

    * sound should be off
    * screen brightness should be fixed @ 50%

    I will do this test tonight and post the results tomorrow so I will have really compareable results, and everybody who is unsure if his battery has a poor battery life should do the same.
