Oh I wasn't talking about bad battery life in general or battery drain while sleeping.
Right now I'm at 100% battery. I unplugged the laptop from power and closed the lid. Now if I reopen the lid I'm getting keyboard illumination but a black screen. Close and open lid again, everything works. Now if I use the device for a couple of minutes it gets really hot and the fans start spinning. The Energy tab in Activity monitor tells me that I have 1:25h left. Now if I reboot it stays cool and I get about 4:30h of battery life.
I can reproduce this 100% of the time. It's definitely caused by the device going to sleep and I doubt it's the NVME drive. It kind of reminds me of how little battery life I got when the dGPU wasn't turned off via the ssdt, that's why I mentioned it. The CPU is not the problem I think, it's clocked super low and there is no real load or power draw. Temps do get hot on the CPU (I'm at 63 after letting it sit in this weird state for a couple of minutes) but that could be the heat of the GPU heating up the CPU as well.
That's just a theory though as I don't know how to check.
That has to be a 2019 model specific issue or there's something in Power Management and the GPU disable parts that you missed. I have never once experienced what you just described. Though you are getting better battery life than myself after your reboot. That's a really odd thing to happen
