How to get my iPhone 6 replaced by Apple for free under warranty still?

Added (1). My iPhone 6 still has warranty till August and I really wanted to go in and get it replaced due to multiple reasons, can you guys tell me about your experiences with these issues and how your warranty worked:
my iphone 6 is a little bent on the top
battery sucks now
sometimes speakers work, sometimes they don't
the touch doesn't respond all the time
anyone know other reasons why they would completely replace my iphone?

Bent? Assuming that was through you, they wouldn't do anything for that.
Battery? They should test it, & unless they find something wrong, wouldn't do anything
Speakers? Likely, if case is proven
Touch? Same as speakers

Well take it in, explain what you did here & see what happens.

  • Will my iPhone still be under warranty? A few months ago I cracked the back of my phone and the other day I picked up my phone and the lock button won't work. I know it's still under warranty because of when I bought it, but because it's cracked can they not fix the lock button for free?
  • Will Apple replace my iPhone 6 that is still under warranty? The home button on my iPhone will periodically stop working for a short period of time, then start working again randomly. Is this something that they would replace the phone for? I've had the phone less than a year.
  • Will Apple replace my crack iPhone 6 if it still under warranty? Like I just drop my iPhone 6 the other day with a shattered screen and I noticed that I only had my iPhone for less than a year. So I was thinking about taking it to Apple to get it replace for free instead of paying. Is that true?
  • When my iPhone 6 screen is replaced by apple, will the home button be replaced as well? Ever since I updated to iOS 9 on my iPhone 6, the home button has been totally unresponsive. On top of this, my phone was recently stepped on and the screen was shattered. I plan on paying the $109 to have the screen replaced from apple, but does that replace the home button too? I've heard that when the front screen panel is replaced, so is the home button/touch id.
