M3 Pro Max battery completely drained overnight - No battery history now

[KFrench]

I just got a new M3 Pro Max last month. It was charged when I want to sleep and I woke up to a completely drained laptop. I turned it back on and it quickly charged up to full again. No servers or anything running and the laptop sleeps on its own normally. The battery was at 0%. The weirdest part about all this is the battery history is *completely empty*

Any idea what happened or what I can check? This Mac is brand new and in mint condition.

Here are some logs showing when the computer died. The internal clock also completely reset after the computer shutoff. I had to resync the time manually in the settings:

It could be trying to do some type of indexing since it’s new. I would leave it plugged in overnight at least for the first week or so

It is not brand brand new. About 3 weeks old. I have used it constantly for the entire 3 weeks. The main concern here comes in two parts:

1. Macs should not run themselves to 0% and hard crash, especially while idle
2. Battery history logs should never be wiped, even if the system suddenly stops.

Settings -> Screen Time -> App and Website usage and see what went on through overnight

Cool feature. It was off for me unfortunately. I just turned it on in case this happens again.

Battery history is cleared on reboot, so that part sounds normal.

Was the lid closed? Did you manually put it to sleep? Or was it running and you just walked away from it expecting it would automatically to go sleep?

Locked, but lid open

I suppose it could've crashed and drained itself in that state, but that is very weird, especially since the internal clock changed time.

I would reset the SMC, leave it plugged in for a couple of days, check on it, and then do the test again. Is there a chance it was set to update MacOS automatically? Wondering if it could've started updating, and crashed during a firmware update or something odd like that.

If it wasn't just a one-off, then take it to an Apple Store. After paying all that money, I'd expect it to be flawless!

Rather than create another M3 Battery drainage thread...

I've had my M3 12 months now, use it 95% at home, mostly docked at office basement desk, sometimes in kitchen table. Last week Thursday took it to my daughters appt 2 hours away, had it in backpack, did not take it out/use it.
Left it there, upon getting it out just this morning was below 5% battery had to plug in.
screen shot of how the battery drained while closed in backpack.

I expected it to be nearly full charge, as never used it. Latest update to system 15.2.
Thoughts / insights ?
