I've been meaning to do this for a few days now. I closed down all of the apps in the multi-tasking bar (you know what I mean...the apps all listed as being currently background running or recently running when you double-click the Home button) Anyway, after having an empty multi-tasking area, I "Rebooted" the iPhone 5 i.e. I held down the Home and Power buttons until the Apple logo appeared, then I timed how long it took to boot up to the password screen...21 seconds Oddly however, all the apps I shut down were there again! I closed/removed them all again. Then I held the Power button until the "Slide to turn off" dialogue appeared and I simply turned it off. Then I pressed the Power button until the Apple logo appeared and, again timed it to get to the password screen...21 seconds! Just for comparison, I tested my iPad 2 running 6.0.1 (same as my iPhone 5) and a "Reboot" took 51 seconds. All the apps I'd closed down were still listed again! A "Restart" from being simply switched off took 21 seconds...a huge difference. I know the processor is faster on the iP5 but really? I would expect a slightly longer time for a complete reboot wouldn't you? Is rebooting the iPhone 5 running iOS6 actually rebooting the phone or just restarting it?
