I haven't read all 35 pages, but quite a few.  I've tried a variety of "solutions" from this and other forums. None solve the problems.  I now have to charge my phone twice a day (and it mostly sits on my desk), power off and on daily, make sure I keep my wifi turned off and close all open apps on a regular basis.  I should *not* have to do this just to use my phone.  I can't believe I'm saying this, but I may have to take a step backward and get an iPhone6 next.
