[T-Mobile LG G4] motoridersd:
Using G2/G3 debloat lists and my knowledge, I used Debloater to disable all the things I don't want/need. Here is the output of the Debloater tool export so you can use this to debloat yours. Suggestions are welcome and I'll be happy to update the list.

Debloater tool - No Root needed (http://xdaforums.com/android/software/debloater-remove-carrier-bloat-t2998294)

My list (file has been attached, and you can import this into Debloater tool for a quick, automated clean up):

It might be in my head, but the phone feels a lot smoother than before. I haven't run into as many slowdowns as I used to.

This list freezes the LG Update tool (to prevent OTAs) and the T-Mobile Carrier IQ package.

Edit: Updated list to include Carrier IQ. Use Voodoo to properly identify if Carrier IQ is running.

Edit 2: Updated txt file by removing Chrome.apk from the list (I use Chrome Beta). The latest list will NOT disable Chrome.
