I have had my XLT standard since mid October. At 100% charge the guess o meter was reading 235 miles. Which with my drive to work and 1 pedal driving, I think was pretty accurate. Even through the 20-30 degrees temps it was around 225-235. I switched over the max charge % to 90%. That gave me 205 on the guess o meter. I charge at work and plug in at night in a heated garage, so I wake up with a full charge every morning. Here is my issue: I tried to change the max charge % back to 100%, which it says it is set at, but the guess o meter stays at 205. And it’s warmer outside and I drive the same route. And it’s been a week. I think there is an issue with the software/tech that’s not actually setting it back to 100% even though it says it is. Anyone else have this issue?

Is the issue where it‘s not charging to 100% or it is charging to 100% and not showing the range you‘re expecting?
If it is the the former, try deleting your max charge setting all together under settings>chargers or in the Ford Pass app under Vehicle>Charging>Charge Settings It might be locked to that charger’s location, hence why holding at 90%. Most likely this is the driver. Setting may even look right on screen/in app but just needs to be reset.
If it’s the charging to 100% then just ignore the GOM and base your driving on battery percentage or the battery % bar. I am willing to bet a future software update will have % more prominent than just range.

The issue is, when I set the max charge to 90%, the range dropped instantly to 205 but it still said 100% when fully charged each time. I went back into the charge setting and changed it back to 100% max charge and it gave an error a couple times before saving. But the range hasn’t changed at all when it definitely should have. Like I said. Same drive every day. I’m not driving any different and it has always fluctuated 5-10 miles with the temps. I think there is something wrong with the software.

You can go in the app and check your driving history to see your kw/h rate. if it is consistent I wouldn't worry too much about it. Often I put my truck on the charger to 90% and it will say it will be at 205miles or so when there but in actuality it ends up at 280-290.
Again, might benefit deleting the location and starting fresh.

What you describe does not indicate there is anything wrong with your truck's software.
After you charge, what %SOC (State of Charge) does your truck show? Does it show 90% when you charge to 90% and 100% when you charge to 100%?
The guess-o-meter is another matter entirely. If that is your concern, you are also the third new thread started on that same topic this week. Please read the following to better understand your GOM:
Don't trust the GOM! Best ways to calculate how far...
In EV forums there are always lots of new threads popping up from first time BEV drivers who are all worried or worked up because their Guess-O-Meter (GOM) is showing much less range than they think it should. This will especially happen in colder weather when the range drops. For new EV owners...

I have had to delete the charging location to be able to reset the max charge level at that station
you might also want to delete driving history data to update driving range if you charge to 100.

When the truck says it is charged to 100%, is that 100% of total capacity or 100% of 80% (assuming that when you are not headed on a long trip?
you shouldn’t charge for more than 80%)
you shouldn’t charge for more than 80%)

That is 100% off the usable capacity.

Question for more experience EV folks....how long is too long to leave at a high SOC?
Example, I think I'm going to have a nema put in my mom and dads for when I head to Fargo I can mostly charge overnight, but I need to get to 100%; I have no flexibility on this. In the morning, I'd typically run over to tailgate, then go to a football game, then start the 240 mile journey home. So, truck would be at high SOC most of the day, but I don't see any other good option.
Thoughts?
If you did this every day, you would see faster battery degradation than you would otherwise. If it happens rarely, the additional degradation would likely not be noticable. It is a sliding scale.
Sometimes we have to use our packs in this way, it just happens. I am closing in on 100k miles on our Y, and because of our travels it has been charged to 100% and fast charged a lot. I am a nerd, so I keep track of capacity. We have lost 2% in three years and 100k miles.
The GMs in the fleet show a bit more wear. It is a combination of pack design and BMS attentiveness. The tech is getting better all the time.
Your mileage may vary.

I've switched and now use 85% as my daily target. Why? I used to charge to 80% but some days it didn't quite finish or it charged to 80%, then cooled down slightly. The result was the blue ring only read 3 out of 5 bars. By charging to 85%, when I unplug I see 4 bars and know all is well.

I think if your alternatives are Level 2 charging to 100% and having it there for several hours vs trying to get to 100% via DC fast charger before you leave town to make it to your next charging option, the high state of charge for a few hours is the lesser evil.If you did this every day, you would see faster battery degradation than you would otherwise. If it happens rarely, the additional degradation would likely not be noticable. It is a sliding scale.

Absolutely. If you are talking a long trip, charge to 100%. Then leave whenever you plan to leave.
