You need to go to settings → apps and then click the filter button (see below if you don't know where it is, drawn very shakily in blue) and select "Show system apps"

To find our culprit, scroll down to the "P" apps, and click on "Personal Data Intelligence". Here's where it's draining your battery: the permissions that it automatically accesses for no reason but to (presumably) put AI stuff/options on there!

Clear the data first, I don't know if it actually did something but it made me feel better.

Now deny all of the permissions it has access to. It's going to show a pop up every time claiming that features of your device (AI features) won't work as intended and you're going to click "deny anyway" for ALL of them.

I don't know if it affected anything, but I also: blocked notifications, set default to other apps so that it wouldn't open, turned off background data usage (in the Mobile Data section)

Also, don't forget to make sure it can't change your system settings!! I don't know what it wants to change, but it might turn the permissions back on and continue draining your battery if you allow it to change system settings.

While you can't do it with this, with other apps you can change the battery usage to "restricted", meaning it will not run in the background (as much) and use less battery!

Here's the results from today, I have used it less than yesterday but it didn't even show up on the battery usage list so I think I fixed it!!

I've also done this process and/or deactivated (bolded ones are for sure AI or similar stuff) (these are my personal preference): AI Wallpaper, Android System Intelligence, Avatar Editor, Avatar Stickers, Bixby, Bixby Vision, Customization Service, Drawing Assist, Galaxy Avatar, Galaxy editing service, Galaxy Themes Service, Game Booster, Game Optimizing Service, Gaming Hub, Gemini, Google Location History, Google Play Services for AR, Hey Google Hotword, all of the "Knox" stuff, LiveEffectService, MDMApp, Meet Installer, Meta App Installer, Meta App Manager, Meta Services, MhsAiService, Modes and Routines, OK Google Hotword, Recommended Apps, Reminder, Samsung Checkout, Samsung Cloud, Samsung Cloud Assistant, Samsung Editing Assets, Samsung Intelligence Voice Services, Samsung Internet, everything with "Smart" in the beginning of the title, Video Effects, Voice Wake-Up, aaaaand WiFiAiService
