Hi, I have read many forums and know that many people have this issue. I have a 64G iPhone 4S and am experiencing terrible battery life. My battery drops 20% doing nothing overnight (6-7 hours). On a normal work day (For me 8.30Am-3.30PM) my battery goes from 100% to zero with very light usage (Making a few calls and few minutes of browsing). I have followed all the steps in forums, turning location services off, Siri off, closing background apps, turning off push notification and many other things off AND restoring but it does not go away. I spent almost as much as my Macbook on this phone and am very disappointed. The first few days it worked fine but now it is acting up. I had jailbroken my phone but now have removed all cydia apps and planning to do a factory reset to see if it helps but from what I have been reading it does not. Is anyone experiencing similar problems? (Stupid question as many are) and if you have, has anyone got a replacement successfully by Apple? I live in Malaysia and unfortunately they don't just hand you a new phone like the U.S (I bought my phone in the U.S) when something goes wrong and I REALLY DO NOT WANT to send my brand new $900 phone for repair. Does anyone have any info on when Apple is planning to deal with this and has anyone had a replacement and the new phone did not have the issue? Thanks Very Frustrated!!
