Battery cells reset/rebalancing after erratic SoC readings

[Cogs79]

Quick update while leaving my Macan unplugged for the last 10 days. The car remained at 80% (what I charge to) for the first 5 days, and now dropped 7% (at 73%) in 5 days. That is the equivalent of driving almost 40 km for me in the summer! I haven't tried the rebalance procedure, and I honestly think it's insane that we need to do that. The car should be rebalancing when plugged in all on its own. I understand checking the app will "wake up" some systems in the car, but I am wondering if having the Porsche status in the iPhone Today View (right swipe) wakes up the car every time I check other app status there. I logged in to the app once in the last 10 days, but check the Today Status (for other apps) everyday.

Mines had this type of behaviour since delivery 12 months ago - my record is losing 13% over 14 days being parked up whilst on holiday. Doing the rebalancing doesn't fix this although it does help with other problems (like fast DC charging ability, range shown at low SoC, Sat Nav arrival SoC estimate). Car is in with Porsche dealer at the moment to look at the these SoC issues and some other minor problems. They are going to do a full battery health check. Not holding out any great hope for a fix this time but you've got to start somewhere.
