Will Apple store or AT&T replace my iphone 5? - 1

My iphone 5 was fine till I updated it, my down volume botton stopped working and it started skipping songs, there should be no reason for me to pay for another phone since I didn't have nothing to do with breaking it, I didn't drop it since I got it three months ago, will they replace my phone or fix it?

Apple store will fix it

  • Is there a store besides Apple that can replace the battery on my Iphone 5s? About a week ago my phone s battery started dying really fast. And I mean extremely fast. It barely lasts 5-6 hours, it shuts off at high percentages. So now I'm scared that the battery is dead and I'm only 14 so I can't pay 87 dollars to Apple. Does anyone know a store that can replace the battery at a lower cost? Or is it even the battery? I'm not sure it is. I will get an appointment to Apple to see if it is the battery dying or not but could it be something else?
  • Is it better to buy the iphone from the apple store or from verzion store? I'm thinking to of getting the Iphone but i go on the apple website and they make it sound cheaper. Then i go to the verizon website and they make it sound more expensive. Which one should i go with?
  • If I take my iphone to the apple store will they replace it? The lock button on my iphone is broken & doesn't work, So if I take it the the apple store will they replace it since i have warranty? Would I have to pay anything?
  • If I take my iPhone 5 to an apple store, will they replace it with a new one? My iPhone 5 has no cracks or nothing like that. The only problem is the on and off button will not work correctly, I have to repeatedly press it hard in order for it to turn on or off. And another problem is at the bottom of the screen there's a green light that's stays on the screen for about 3 seconds or so. I got my phone last year, so my warranty is up. But if I take it to an apple store and show them what's wrong, will they exchange it for one that's never been used?
