On my LGV10 / Verizon I have the following disabled, not exactly sure how this translates over to Samsung / Verizon. I think I completely un-installed some bloat too, I don't remember what they were though. Overall Verizon bloatware is not that bad. The MyVerizon data usage widget and Message+ bloat apps are really good.
Amazon (App was constantly running in the background and depleting battery excessively. I access Amazon through browser)
Amazon Kindle (No need for this, would randomly deplete my battery in the background)
Android Pay (No need for this, would randomly deplete my battery in the background)
Verizon cloud (No need for this, would randomly deplete my battery in the background)
Cloud Print (No need for this)
go90 (Verizon mal-ware, google it for details, delete / uninstall if at all possible)
Google play movies & TV ((No need for this, would randomly deplete my battery in the background))
Google play music ((No need for this, would randomly deplete my battery in the background))
Hangouts (Useless and un-needed)
LG OEM Music player (doesn't play ALAC lossless audio)
NFL Mobile (I have better ways to get my updates)
Slacker Radio (No need for this, would constantly deplete my battery in the background)
ThinkFree viewer (Useless and un-needed)
[EDIT]
Now I remember, it was Facebook that came bloated... deleted that POS after trying 2-3 app stoppers like Shutapp and Greenify they couldn't throttle it down. FB was always running in the background and draining my battery at ~10-15%. Drove me nuts, made me feel like I was back on an iPhone and the Borg collective was in control!!
