After jailbreaking an iPhone 4, will my battery drain faster? Are there apps that I can install that will lead my iPhone 4 to lose battery faster? Obviously if I install an emulator or a game, that will drain battery, but I don't want having apps running in the background constantly draining battery. From what I understand with the non-jailbroken iPhone 4, even though multitasking exists, you don't have to constantly "quit" out of apps to save battery life because it pauses them. Will this continue to happen after jailbreaking? Is there a way to monitor if it is not happening?
