DNA250 auto power down time?

[knew]

Hello all , this is my first post.

I've got my first DNA devices about two days ago (Lost vape Therion 166)
a little things that i confused is..

my device turn to full power down if not press any button in 36min. (when press fire button after that its show a Welcome screen , 35min or lower it's a normal sleep mode)
   
but i've search about it, i found other people says hard sleep or full power down will activate in 1hour if not press any button)

1. My device performing properly or not  ?
2. How much time that DNA250 device will go to full power down automatically ?


Ps.  sorry for my broken English  .
Thank you.

The welcome screen will show when bringing the mod out of sleep mode... and after changing batteries with no usb attached
