I was super satisfied w battery life of my new iPhone 4 the first two days and until it ran down to 1%. After that I think it decrease too much and almost 1% per minute when surfing. But one thing I might be wrong is killing apps in the multitasking menu. Will that increase or decrease battery life? I am thinking maybe it will decrease rather since it is more of an effort to reload the program then having it idle in memory. Am I wrong and what else could affect battery life? I have fixed usual suspects, brightness, location services and push services... Could I have a bad battery? Any insight appreciated!
