dgzeij I am not sure. My original question was asked about hardware or software.
However, I have found one app that was making thing way worse. I was sick of the auto brightness being too dim. So I tried an app called "Velis Auto Brightness." It tries to give you it's own auto brightness with full customization. However, since the Fold wont allow native brightness control, it uses an overlay instead. But in order for the overlay to work, the brightness is pumped to 100% in the background, and the overlay dims from there. The app doesn't make this obvious, but I eventually figured it out. ... so back to stock auto brightness. I would love custom control/profiles/ai learning/something better for auto brightness in GOS.
However, the phone is still warm, and the charging is very slow. Something is still up. Even when I plug it in to charge, the screen saver will say "Charging Rapidly - Full in 59 min" for example, but 59 minutes later it will be NOWHERE near full charged.
Is there a way to see all the apps that are not "optimized" for battery use in one place? I know I can go to the individual app and then to battery to check the settings. However, on my Samsung, there was a page that listed all apps that were optimized and another list for unrestricted. It made it easy to check on those permissions at a glance and find the culprit.
