Well friends, brothers and sisters, it seems to me like I never have had any luck with Apple Products and their battery life. My Macbook Pro has had to get it's battery replaced twice in less than 2 years. My 2nd gen iPod touchs battery lasts me about only half a day just listening music, and now, my first ever iPhone, an iPhone 4, is giving me the same luck. I bought it on launch day so I have had for almost 5 months now. So I have been having this problem for about a month now. I have tried to power cycle or hard reset, calibrate the battery but to no avail. In the first month of owning my iPhone I was impressed with the battery life, because it was really long! At 100% it would take like 40 minutes for it to go down to 99% just listening to Pandora Radio... and the remaining %s like 10 minutes to go down 1 by 1. But My Battery at 100% only lasts like 4 minutes which is supposed to be the longest lasting percentage.The remaining percentages only lasts like 2 minutes! When I sleep at night I leave it at 100% but when I wake up after 6 hours of sleep it's in 98%... before that didn't happen... and it's suppose to be able to last 300 hours in standby mode.! It is running on the latest firmware 4.1! I don't even have a case for it so heat is not a problem. And I'm in a cold region in California so that isn't a problem either! Will I have to buy a new iPhone? Will I have to pay for a new battery? I did, once however restore my iPhone 4 and restore it from a backup from the same iPhone 4... don't know if that's an issue. Please please help! Thanks!
