[Samsung Galaxy Note 9 Real Life Review] gamekill:
Mine is Snapdragon, but if you are still interested, this is what I did:

1 - Enable USB debugging on your phone by going to Settings -> Developer options
2 - Use ADB ("minimal ADB and Fastboot" is OK)
2a - FIRST OF ALL:
adb shell
2b - TO LIST ALL INSTALLED STUFF (if you want to check):
pm list packages | sort
2c - To disable a package you write:
pm disable-user --user 0 packagename
(Example: pm disable-user --user 0 com.dsi.ant.server)
3 - TO UNDO: just replace the "disable-user" word with "enable"
pm enable --user 0 <Package Name>
(Example: pm enable --user 0 com.samsung.android.easysetup)

Below is my personal list, I am sharing it as you asked. However it may not fit your needs exactly. For instance I left Facebook App off, but I had to leave Facebook App installer and Facebook service on, because I use a Gear VR. Also I left com.samsung.android.lool on, because I like checking battery usage, and you cannot see that graph without this package service enabled.

[AFTER my personal list I am also pasting a "full" list of all services safe to disable.]

So write, or copy/paste these commands on your ADB Shell window. You can copy/paste the whole block and press Enter at the end and all of them will be run one after another quickly:
