I have none of these problems with a 6 plus. Maybe backup, factory wipe + restore, or go to an apple store and ask for help?

Also, what do you mean by "atrocious"? I get 1-2 days with heavy use.

Finally, the 5 phones I've seen this week seem snappy enough, and so does my 6 plus. It really sounds like your phone is screwed up.
