The Australian has put himself in prime position to win his first major after shooting an eight-under-par second-round 64 at St Andrews.
The 28-year-old now finds himself in the lead on 13 under par ahead of the second half of the tournament.
Smith's 35-hole aggregate of 131 is a new record for an Open Championship at the Home of Golf.
The player has remained relaxed away from the golf course by watching episodes of Peaky Blinders - the British gangster drama.
With a late start now guaranteed on Saturday, Smith doesn't plan to change his routine.
"I'm watching Peaky Blinders at the moment," said the Aussie, whose round included six birdies and an eagle at the par-five 14th.
"I spent a bit of time talking to folks back home and watched two or three before I went to sleep (on Thursday).
"I probably will do the same thing tonight. Might watch a few more, just trying to stay up a little bit longer.
"I think I'll probably try and stay up as much as I can. I think I'm going to be a little bit tired. I'm just trying to have a really big sleep in.
"I'm not going to try to do anything for the morning - sleep in, get on the bike, get the legs moving and get prepared as I normally would every other day."
Rain on Friday morning slowed the speed of play at St Andrews, however Smith expects things to quicken up ahead of this weekend's action.
He said: "I think being off late again tomorrow afternoon it's obviously going to be a bit firmer, more like the first day. So I would say it's going to be pretty brutal out there."
