M3 LR Battery Drain on Lockdown?

[McNulty]

Hi, I have a M3 LR that I picked up in August 2019. Totally happy with the car to this point. It's been sitting mostly idle in my drive for the last 6 weeks while the UK has been in lockdown.

I charge once a week to 80%, its not constantly plugged in as I don't have an external charging point. A couple of weeks ago it started to lose a lot of range each day - approx 15 miles per day.

It doesn't seem to be related to a particular software release, the car has updated twice since it has been idle (currently 2020.12.11.1), but the issue occurred a week after the first update and before the second. I'm not running sentry mode and the climate control is off. Last week I rebooted the car to make sure that there were no zombie processes running, this made no difference.

Anybody else experiencing this? Any idea how to fix it?

Thanks in advance for your help!

Is Sentry mode on? That eats about that much power

For what it is worth, our August 2019 LR AWD was last charged on 19th April. That charge was to 85% which gave an indicated range of 248 miles. Since then we have done 119 miles and the SOC has dropped to 23% or 65 miles. So over the course of nearly a month we have used a nominal 183 miles of range to do an actual 119 miles. That, I think, gives a slippage of 64 miles which equals about 2.37 miles per day. Some of this is down to my driving, so phantom losses pretty small

Now come on ... admit it ... you didn't read the post did you!

Do you have your phone in Bluetooth range of the car? Perhaps it's not going to deep sleep very often.

Parts of my house see my phone connect to the car (and of course my daily walk past it each day ). I get a few miles lost because of it.

If I turn Bluetooth off, I get zero phantom drain. 0 miles lost

I’ve walked past the car many times with my phone in my pocket and it’s not coming out of deep sleep.
