6 Stupid Ford (Sync 4) Settings That Are Draining Your Battery - useful? AI video.

[HeyBales]

Video Summary:

Six Ford Sync system settings that can drain a parked vehicle’s battery:

• Wi‑Fi hotspot: The built‑in hotspot stays active even when parked, using 85–120 mA continuously. Disable hotspot broadcasting when not needed.
• FordPass / connected vehicle mode: The telematics module remains semi‑awake for remote access (40–80 mA). Set Connected Vehicle/Telematics to reduced connectivity.
• Wake‑word monitoring: “Hey Ford” voice activation keeps microphones and processors listening (30–60 mA). Turn off the wake‑word feature and use the steering‑wheel button for voice control.
• Automatic over‑the‑air updates: Sync may power up at night to download updates, drawing over 300 mA. Switch updates from automatic to manual.
• Extended vehicle activity: This mode keeps Sync components running for up to 45 minutes after shutdown (25–40 W draw). Turn it off unless you need it.
• Bluetooth polling and contact sync: Sync pings for devices and updates contacts even when idle. Disable automatic contact download and connect manually.

Overall: Turning off or limiting these features prevents unnecessary battery drain when the vehicle is parked.

Great summary.
Now let's get the fact check added to those items, specific to the forum for Mavericks it's being posted in.
Several have mentioned some of those don't exist at all.

For example - the FordPass line - that many mA for a sec once per hour. That's it.
And actually, the service manual expected total avg value while sleeping - 25-50 mA.
But I've seen it float below to 18 mA, and above to 65 mA.

I'm doubtful of several of the others - unless sitting there in Accessory mode.
In which case if battery is low - your Acc mode is turned to Off for you after some minutes.

Good to know!
My 12V battery's state of charge is dropping at a slower rate since I disabled as much as I could find in the infotainment center. Can't be positive though with rapidly changing local temperatures and inconsistent daily vehicle operation at this time.
It would be great if someone could list which amp draws apply to each group of Mavericks, 24's, 25's, ecoboost, hybrid, etc.

When in sleep mode - still given as 25-50 mA for all of them.
Service manual for pre-25MY said 75 minutes max to reach sleep mode.
Someone posted 60 min for 25MY, guessing 26MY the same.

The hybrid has a fuel tank pressure test that is done when between certain % full (forgot what the PID said), but I'd bet that runs during the drowsy mode before sleep.
Service manual had no values for that chunk of time - that would be the interesting info.
