Not sure about other users here in ehMacland, but other users are experiencing this same phenomenon- poor battery life after updating to IOS4 on their iPhones and iPod Touch's. I am on my iPod Touch. The battery is draining overnight even when turned off. When I first noticed it, I soft reset the Touch, but the battery is draining once again. Not good. Anyone hear of any fix coming?
This new multitasking seems to drain my battery very quickly. If I don't close all the applications they just keep running. I have not tried to see is the battery drains overnight when the iphone is shut down but I will try. I wish they would make an update that would enable you to turn multitasking on and off, I don't use it and I doubt I ever will.
