Thanks for the detailed information. I don't have stand alone WiFi operational on the Maverick, so I would guess the vehicle relies on cellular for any updates. My AT&T signal is minimal at my house, however, I do have access to a strong WiFi signal in my driveway.That update option is using WiFi, and from testing, while it may turn on once overnight to check if there is an update, the system is turned off otherwise (meaning it'll drop off the wifi network quickly). Not a likely reason for draining battery.
And WiFi is a small power-drain even when it's on the edge of the wifi signal and has to turn the radio up in power to use it barely.
The ATT cell modem though for telematics - not sure how often that is checking in to pass on data the Ford app is using, but cellular network uses a tad more power when you have bad signal, or no signal and it's constantly searching for it. That's constantly connecting so you can do your remote start or lock/unlock thru the app, besides info given.
Got good ATT network in your normal areas, especially where parked?
