STAMINA mode improvement

[azzido]

Hi,
I would like to ask for the following stamina improvement:

Currently the phone is going into deep sleep after about 15min. 
Would it be possible to control this time? For example I would like it to go into deep sleep faster, let's say after 5min after screen is off. 

Thank you,

it's controlled by a battery saving feature called Doze, and Google explicitly forbids OEMs to modify Doze behaviour in any way.
