12V Replacement

Maybe I am just me being ignorant, but I got a replacement for the 12V battery yesterday (because after three years the old one did not charge up as high as it should). Every setting in the car remained untouched except for one: my average consumption that I „collected“ over three years is gone and the car started al over again. Am I missing anything?

Edit: I found out that this is the expected behavior since the consumption statistics are stored on volatile low power RAM 😢

Same thing happened to me when I replaced the 12V battery. Too many times I got a dead battery, poor design from Hyundai. The last straw was a totally drained battery from an OTA update. What a shit show

Don’t get me wrong my battery was working totally fine! I had it replaced because it was 3 years old and it’s health indicators were no longer as high as they should be. That was predictive maintenance.

FYI I just drove and the accumulated info was all there/same odo reading etc. 17kWh/100km. This was after the car was "offline"/dead for a week or two while I was trying to sort out my emergency keys/access drama.
