2022 Premium Mach E battery junction Box recall

[rbf1153]

I own a 2022 Premium and just recently had my junction box recall repair......previously on a full charge with extended battery I ( only 4.1 miles) from work would still have 100% battery for 2 full days......at the end of the second day......I'd be at 98%......ever since my junction box was repaired due to the recall......I drive 8.2 miles on a full charge 100%......when I arrive home I'm at 98% in one day.......so today at the end of the day had to go look at a home to purchase and this morning on a full charge 100%.......so 320 mile range fully charged on my Mach E at 100%.......at end of my trip my battery was at 90% with a 305 mile left as it says on my screen......so went 15 miles and down 10%......weather was not a factor being 81 degrees......my question IS THIS NORMAL?......Im stating NO..........
Appreciate ya all

The driving history probably just got reset. Why are you charging to 100% when you have so short a distance to drive?

I usually plug in evey 2 to 3 days....but after the fix was wondering why battery was draining faster than normal......so am experimenting before I contact either Ford or dealership......this is my second Mach E for my 2021 was a LEMON......so not becoming a fan

Not really sure I follow exactly. However, I have noticed that previously that when I charge to 100% and precondition, I could drive maybe 6 or 7 miles before the reading it dropped below 100% after that, it would become more consistent by dropping a percent every 2.7 or so miles (depending on conditions)..

So the delayed drop from 100% to 99% (or lack thereof) shouldn't be a concern. I chalk this up to the fact that the voltage drop is not linear and is steeper at the extremes, and thus the precision of the reading is not as good.

As for why you'd see a 10% drop for 15 miles (so 1.7 miles per kWh if i estimate correctly), it's hard to say, you noted the outdoor temperature was 81F, was that during the day, during the night, when it was being changed? These temperatures can impact three percent change readings.
I'd recommend just driving it like normal, charge only to 80% and then look at the miles per kWh over time instead. This would give a much better representation if the battery is draining quicker than expected.
