HTC Desire HD and Desire Z Booting Up in Just 5 Seconds

HTC Fast Boot was introduced when the HTC Desire HD and Desire Z was announced. This basically puts the phone in a hibernated state, where it stores data in RAM for faster boot-up time. This is of course distroyed when the battery is removed, since it’s only in RAM. On a ‘clean’ start the phone takes about 1 minute to boot-up.
