Hi all, This is my first post on the forums and I really need your help. I got my iPhone 3GS last July, and I have used it over the past 6 months. Now, the life span is very short. This is my problem: I charge the battery overnight in my dock so I can use it as an alarm, and when I wake up in the morning to go to school, I'm 15, I listen to the music on the bus ride, which is only about 10 minutes. When I get to school, the battery life is at 96 percent, which I find normal. I then put my phone on silent and press the top button to put it on standby/hold throughout the school day which is 8 hours. I do NOT touch it during the day. When, at the end of the day, I try to listen to music at the end of the day, it has 1% battery left, or it is already dead. What happened? This NEVER happened before, so why is it happening now? Please try help me by telling me why this is happening. P.S. I HAVE SWITCHED OFF DATA ROAMING, BRIGHTNESS IS AT A MINIMUM, AND ALL EXTRAS ARE TURNED OFF THANK YOU SO MUCH, PLEASE TRY AND HELP ME!
