For Non-Samsung phones
Set your Android Phone to Automatically Power on when USB Charger is plugged in
Because Samsung can't do Fastboot the above method won't work, but it comes down to going to fastboot mode and typing
adb reboot bootloader fastboot oem off-mode-charge 0
For Samsung phones
Auto-starting Samsung Android phone when charger is plugged in.
Ensure busybox is installed first Busybox by stericson Note also that if you install to /sbin you will lose it all after reboot, so install to /system/xsbin
adb shell mount -o rw,remount /system
Note: start in recovery mode (twrp) and mount the system partition here. If the phone is started then you can't perform the /system remount.
cd /system/bin
