Apple is replacing iphone 5 batteries, check to see if you qualify. This has been a huge issue for me, my phone shuts off at 20-30 percent remaining.

Had the same problem, finally had enough and decided to buy a replacement battery off eBay and replace it myself a month ago. I don't understand why it took almost 2 years to notice the batteries were faulty, mine started acting up a almost a year ago.
