Battery discharge when idle?

Yeah, you’ll get next to nothing drain when the MG4 is asleep.

Just to reiterate what's already been said from both sides. I had a model 3 before my MG4 and the 1% per day is about right. It's more when using sentry mode, I'd say 2 or 3% a day. There's other features like cabin overheat protection that'll turn fans on when it gets hot, that'll also use the battery.

My Mg4 has no noticeable battery useage when off, which is great!
