MacBook Battery Drain in sleep

I am having the same issue on a MBP 13" 2020 (Sonoma 14.3.1). The battery drains completely on sleep mode. I find the mac at 0% after couple of hours. I have been having this issue since the past 2-3 weeks. After looking at your post I suspect it to be a software issue probably, since your mac is relatively new. And hence the battery would be in good condition, which otherwise I was assuming to be a battery issue with my relatively old mac although it still shows "normal".

I'm having the same problem.

I've closed all programs and this morning picked it up and it was warm, when it should have been cold (cold room) my battery readings appear identical to the image.

Th laptop has obviously been doing something, but all the updates are turned off and there is nothing else open.

any ideas gratefully received.

I'm having the same problem with a MacBook Pro 13" from 2019. Turning off Wifi and Bluetooth before putting the laptop to sleep "solves" the problem, the battery doesn't drain anymore overnight. But it's a pain, since there is no fast way to toggle WiFi and Bluetooth. For WiFi it's possible to launch an Automator script with a keyboard shortcut, for Bluetooth I didn't find anything similar...
