/* Info */
QuickBoot is a Cyanogen OS feature developed by Qualcomm and Cyanogen for OnePlue One.
The goal is to reduce the boot-up time drastically by altering the shutdown / boot-up sequence.
See QuickBoot in action :
Rather than turning down the device completely,
QuickBoot turns the device into Airplane mode, kills the applications, disables notification and button reactions,
similar to how Windows 8 does.
Note that "reboot" actions remains normal, meaning the device will go into full shutdown / restart on reboot actions.
But because of the device is not completely off, devices with removable battery should use this with caution
as pulling off the battery during QuickBoot active can potentially cause data loss.
For devices with removable battery, I personally recommend using "reboot" and wait for the screen to go off and then quickly replace the battery if needed.
The battery drain during QuickBoot is active is equal to the state of all applications killed & airplane mode.
This version of QuickBoot is taken from CyanogenMod 12S and modified to support Android 5.1 and fix several NullPointerExceptions.
