    I have had this problem for a while now, my iPhone 5 has been dying with at least 20% battery, sometimes even nearer 30% battery remaining and I had learnt to deal with it.

    I got a replacement iPhone 5 in December 2012 after the lock button broke and it has only been happening since I got that one.

    Like I said, I had learnt to deal with it until now. It has recently been dying at 40-50% charge and wont turn back on for another half an hour to an hour.

    I decided to research and found out it happens to a lot of people.

    I have re-calibrated the battery and that didn't work. Just wondering what I can do? Or what you've done if its happened to you.

    I live in New Zealand and we have no Apple Retail Stores, so that option is out of the picture.

    My mom's iphone had a similar problem. I guessed that some rogue app is doing mischief and restored phone clean.

    Then I installed only apps which she requires one by one daly.

    That has solved her problem.

    Your battery is toast.... Batteries sometimes fail.

    Call Apple support and ask them what to do. I suspect you can send it in.

    This is what I think too. I wonder if the replacemt phone was new, it might not have been. My view is the batteries last 18 months or so and then you can start seeing problems. If Apple cannot change your battery find a local tech shop or do it yourself (see online guides/videos like ifixit)

    My verizon 5 does that around 13-20%

    Plugging in charge cable however turns it back on immediately.

    I rang Apple and they did a quick diagnostics test and discovered I have a defective battery.

    I didn't know the phone was still under warranty either (thought it was 12 months, turns out its 24 months) so sent the phone and awaiting either a free repair or replace, they haven't told me which yet until they get their hands on the device.

    Thanks guys. :D
