When the truck was new it would go into sleep mode about 10-14 days after last driven. Now I drive the truck more and it seems the truck goes into sleep mode about 8-12 hours after last driven. My trips are minimum of 100 miles so I dont think its a short trip issue. Ford just replaced bother batteries 3 days ago.
Has anyone experienced this and were you able to change a setting or something?
I bought my truck in November and have it parked until spring as I am not going to winter drive it. I noticed the deep sleep mode as well after a few weeks. When it enters that it wont respond to commands on my phone, I have to go to the truck with the fob to start it. I do run it to move it occasionally while I am doing snow plowing or need access to something its blocking. It always takes a couple weeks before it goes to deep sleep again.
Is your truck still going into an early Deep Sleep mode with the new batteries?
HTH,

yes it still goes into sleep mode with 2 new batteries in about 12 hrs. I wanted to get two new odyssey extreme batteries but wonder if it will allow the truck to not go into sleep mode for a longer period or is there something else going on

My 2020 had 8k miles on it and went into sleep mode about every two weeks. I now have 15k and have noticed the truck goes to sleep much faster than usual
did they change the Battery junction box? there is a tsb on it
mine got changed and batteries stayed charged for more days,
but still does the drop toe 60% in a few days, and deep sleep is set at random. its been sitting now for 5 days, no sleep but last week one day it went to sleep
it has no reason imo

Better get a maintenance charger on those batteries. My guess is they’re already heavily sulfated.
You can reset the battery monitor. Maybe they didn't do it at the dealer. You need a fancy scanner, (not a code reader). OR just unplug both batteries for 8 hours. This is what i did on my F150 & it worked. Should be same on superduty.
It doesn't sound like there are too many conditions that cause the truck to go into Deep Sleep mode. It is odd that some trucks are going into it without any of the conditions being present or met.
When batteries get replaced the only thing the manual says is...."After battery replacement, or in some
cases after charging the battery with an external charger, the battery management system requires eight hours of vehicle sleep time to relearn the battery state of charge. During this time your vehicle must remain fully locked with the ignition switched off."....I'm sure your truck has sat for that length of time or longer since the battery replacement was done.

i bust out laughing every time i read the above
mine will go to sleep in less than 24 hrs, battery at 12.4, again overnight..70F outside or if a bird craps on the hood.
