I have owned my iPhone 3GS for a little over a month now and it has been an incredible phone. The battery life was a large amount and lasted through my day. Recently, a waitress accidentally spilled coke on my shorts and inside those shorts was my iPhone 3GS. The only thing protecting it were the pockets. It was very sticky when I took it out but appeared to work perfectly. A day afterwards, I am noticing a huge decrease in my battery life. The battery percentage seems to drop almost twice as fast. At times, doing the same routines such as checking websites, the percentage is much lower than usual. At times where it would usually only loose 2-3 percent, it is loosing 4-6. I checked on Apple's website and I still have a warranty. Should I waste my warranty now or wait and see if a new update would fix this? Resetting did not help and I don't think restoring can either. I have not changed any of the settings this whole time. Even when turning down my brightness, the battery drops even faster than it did on a higher brightness setting. Please help.
