My iphone 4 battery seems to be draining way too quickly. I just charged it up to 100%. Disconnected it and made sure that the following things were turned off: wifi, location services, notifications, mail. I double clicked the home button and closed all applications. I am using 1% battery per hour. Usage reads 2 hours 5 minutes. Stand By reads 2 hours 5 minutes. Does this make sense? How can usage and stand by be the same when I have done nothing except hit the home button twice and looked at the battery strength? Any ideas?
