So, my battery is dead. Jumped it twice and within twos minutes I get a warning that the car is being turned off to save the battery.
I am getting it towed to the dealership.

Let us know what they say as Iām going through the same thing. A lot of short trips kill the battery quick. Thereās way too many things on this vehicle that requires power and the fact that the system takes 15mins to shut down(sleep). Idk why Ford didnāt put in a better charging system? My issue is a bit different as I know there are 3 fuses on the acm that have a parasitic draw. Iām getting ready to trek 3500 miles back home in 6 wks and I donāt trust the dealer will fix it or have parts in that timeframe. It was in the shop for 7 wks before while they replaced a battery and alternator a still didnāt fix it. They then said they wanted to replace the computer and I said nope and took it back. I use a trickle charger a couple times a week. Long trips should help you if there arenāt any other underlying problems

Short trips should have nothing to do with it remember this truck comes with a.s.s.
Read the volt output on the dash. Should range from like 15 down to 13.
I can leave my Bronco easily for a week with no issue. I have my PowerStation plugged into the rear cargo as well as my GMRS tapped into the Cig lighter...basically I have things pulling power for up to like 45 minutes after turning off the bronco...and never once with my short trips had an issue.
If your battery is going dead while you're sitting, you have something drawing power that shouldn't be... If your battery is not charging after 15 minutes of running, you got something wrong with your charging system.
Almost every one of these types of post end up being some sort of accessory add-on that's either wrong or wired wrong.

Have you also been having issues with your modem / Ford Pass app not working? This is what killed my battery. Dealer did a TSB, good to go, hasn't happened since.

In my case I havenāt been able to connect to pass since 4/20 and lost navigation then also. Dealer tried to tell me no navigation due to low battery. Not so, as Iāve disconnected all accessories and trickle charge the battery every couple of days. Making sure to connect ground to the stupid ass bms so it can sense current. In my case I strongly believe itās the acm
Mine if not being driven is 24/7 on a Deltran Battery Tender. Battery is always at 100% and ready to go.

Why do people think this is normal to do? Have you ever done this with a daily before?

JMO, but I agree that a tender is a good idea, (I'm retired and sometimes don't drive at all for several days), MY 2018 Raptor started having all kinds of technical gremlins at the 3 yr. mark, key not detected while going 65 mph and key sitting on consloe, ASS stopped working (actually liked that), would go into battery saver mode one minute after shutting off engine, mirror memory went a bit nuts, and other warnings that weren't real. Took it in and the battery was just starting to fail...replaced and all back to normal. Not apples to apples I realize, good luck!

Agree, if you're driving it daily, all else being normal, shouldn't be needed, but if it sits at all between driving, i.e., weekend toy, then a tender would be a good idea. I have my m-cycle on a tender...

uh oh...same thing happened to us. TCU (modem) bit the dust after killing the battery. Its been busted ever since. Dealer has been working with Ford for over a month trying to get this fixed. Replaced TCU and now cant get it programmed to vehicle. Now the radio is lagging out, acting super slow. Hopefully a ford engineer will figure it out before they just burn the whole car down.

Sounds like my exact situation. I have a huge road trip back home in august and Iām thinking of just dealing with it when home. Our meandering will put us at about 3500 miles. So I think Iāll deal with it later.
Similar thing here I suspect. My modem was dead for a few months. My battery was running low (to the point where the whole auto shut down and wouldn't restart after ASS kicked off when I was at a busy red light).
Dealer charged up the battery and took out the modem. No more issues over a few months waiting for the modem. New modem installed and things continue to be fine.
