Hi,

At least you have changed the battery, I would also recommend restoring your iPhone in iTunes. That did work for me.

sergiy, it is easily possible that you are having corrosion failure. I would suggest that you take the time and clean your iPhone. Use these guidesto work on your phone. This guide will show you how to clean it. It was written for a 3G but all the points are still valid for your phone. Once you have it properly cleaned, take a look around the power management IC as well as the dock connector. Look for charred, or missing components.
