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.
