    Hi, new here. I got an iPhone 4 in August and had a battery issue....After about a month my phone would just power off with 30% battery life, then 40%, then 50% and finally 60%. I would go to turn it back on and it would display a battery drain and I would plug the phone into the wall charger and it would turn back on and continue charging from where it powered off. I took it to the genius bar and they replaced it with a new one, now I am having the same problem. I did a reset by pressing the home and power button but to no avail. Has anyone else had this issue? The guy at genius bar said he hasn't heard of it before. I was planning on resetting back to factory settings when I get home from work but wanted to see if anyone has experienced this before. Thanks!

    A little background:
    I only have apps that I use often, about 6 or 7 apps.
    Never had contact with any form of liquid
    Never experienced the overheating of the phone itself while charging or others.
    I close apps once I'm done using them.
    I use 3g more than wifi when using the interwebz.
    Haven't dropped it or crushed it, etc.
    I never leave it on the charger after it reaches 100%

    restore it to factory settings when you can does it run on 5.0.1 or other run the battery out completely until it shows less than 2 percent delete all your apps and all e-mail settings take out the sim and start again remove all music and start again

    Cool, thanks BMahoney. It runs OS 5.0.1, now that I think of it it started doing this again after I updated OS. I will try the factory reset tonight when I get home. I can't let it run down to 2% because it is currently powering off at 56%

    you might have a phone problem as well if its under warranty tell them you want a new phone as battery was changed already sounds to me like its a software or memory issue when i charge mine i wait until its completely dead and i then charge it overnight again maybe 7 or 8 hour to a charge my phone is 14 months old and never game me an ounce of grief
