Among the great debates of computer technology (along with whether or not to shut your computer down for the night or put it to sleep and how this affects the hardware) is the question as to whether or not to charge an iPhone or similar device via an outlet or USB port. Even in the case of charging an iPad, where the user receives a “not charging” message near the battery indicator, the device is charging, but slowly.
The guys over at When Will Apple? took the time to do a pretty decent job of comparing charging times on the iPhone 4, comparing USB to AC outlet. The conclusion: USB charging takes 23% longer to charge an iPhone 4 than charging via an AC outlet. If you’re in a rush to charge your phone, that’s a pretty significant difference.
The little flaw in this test is not knowing the amount of charge coming from the USB port used, as not all USB ports are created equal.
