I've had my MS 90D set for charge or top-off at 12AM for months, since delivery. My MS has been plugged-in to my HPWC and not driven for a couple days, when my MS last topped-itself off to 90% beginning at 12AM on 5/13. It's only had normal daily vampire drain since then. In the past, MS has always, without exception, began any charging activity to top-off per my set schedule at 12AM. When I keep MS plugged-in and not driven for a few days, it tends to skip a day or sometimes two before topping-off, but has always begun what it wants to do at the scheduled 12AM.
This morning, I hear two charging alarms on my iPhone first at 4:01AM that MS charging had begun, starting at 242 RR miles, and another alarm when it ended a few minutes later (at what's normal for me as 251 RR miles @ 90%). As you'll see in the 3rd photo below of my 17" CID, scheduled charging remains set at 12AM. Temperatures over night are well above 60-degrees here as they have been for weeks. Power was not off in my home this morning, and again, as the 17" CID photo shows, power is flowing properly from my HPWC -- there were no charging interruption messages that came through on my Tesla app. I've had 7.1 2.17.37 installed since 4/26 with 3 previous scheduled charging sessions taking place at 12AM as I expected.
Why would my MS decide to charge itself off-schedule?
Other Recent Oddities Related to Power?
Always Connected ON Not Utilized
While it may not be related, the other recent oddity is I went to check status of my Tesla via the Tesla App on my iPad earlier this week. For the first time ever, I received the message saying my Tesla was being waken-up, and that I should set Always Connected ON if I don't want to wait next time... BUT, I do have Always Connected ON and have had for months. I went out to my MS and it immediately rebooted and woke up from deep sleep. (I have Energy Saving ON, Range Mode OFF.) I verified Always Connected was checked, as it always has been. This has not repeated, but it's also strange, isn't it?
Sleep after <10 minutes
The other thing that has been happening more frequently in recent weeks, perhaps since 7.1 2.16.17 is my MS sometimes takes longer to come to life when I open the door... I can sometimes run a quick errand, be gone for no more than 10 minutes, and when I come back the infamous "wait until MS powers-up" message comes up on the IC, or my IC or CID may initially be blank before displaying the Tesla T and then coming-to-life. Something has changed, but it's not repeatable enough for me to consistently describe, or even report it to Tesla quite yet.
