I was thinking about using Push Notifications, don't currently due to concerns over power consumption. So does it matter how many services I have enabled or will it use the same amount of battery regardless of how many push services I have turned on? Also, roughly how much additional battery does Push use over a 12 hour period? One more thing, I seemed to have trouble with Push Notifications on my iPad when I was at home. Could this be due to ports not being open as it seemed to work 90% of the time at a friends house...?
