I have the same slow wake up on Boyue T62 with the Boyue firmware (lastest).
I've tried a lot of power button press patterns. None is really consistent.
Sometimes device wakes up if keep pressed for like 3-4 seconds. But sometimes not.
Pressing 3 times quickly: sometimes wakes up, but sometimes rebootes, other times partially wakes up (eg: devices freezes).
Also to put in sleep mode the power button doesn't really work. I need to press it at least twice to realize it ...
