i posted on another thread.. https://discussions.apple.com/message/22928396#22928396
However, this thread describes the same issue i've been having this week.
in the diginostic area from settings.. i see the crash list and it lists..
As of today, it was crashing very very frequentely. Going to try to run the battery dead and see if this changes anything.
I did not have this in the log. Mine listed the following:

Just a follow-up to a earlier post in which my iphone 5 still on iOS6 had the battery drain to zero when the camera was briefly used even when battery was at 40%. I may be the minority here still on ios6 but today I experienced a different type of dramatic battery drain. I was at around 70% battery when I started to do some web searches on the phone and within 30 min of use I was under 35% and quickly to less than 20% after a few more minutes of use. I wanted to get the phone now to 0% so I could try and calibrated the battery by instructions previously provided on this post. Now after using the phone for over 90 minutes running different apps and web searches the phone has not decreased lower than 15%. Basically the battery is staying at 15% with no further decrease for 90 minutes when it lost 50% of battery within 60minutes of use. Certainly seems to be a battery calibration issue. Still working to compete multiple battery drain full charge cycles to see if recalibration helps.
OK as an update, I spent about an hour with Apple support who believed it was a software corruption issue, so have done a full restore.
Phone ran well all day yesterday after a single charge in the morning. woke up this morning with the 'phone at less than 20% warning' which is understandable and sure enough it was showing 20% (This does represent a 16% use overnight when the phone is not being used). I made 1 call of 1 minute maximum first thing and afterwards the phone showed at 13% (7% useage on a 1 minute call - I think not ). So I plugged the phone in (using the apple supplied charge plug and cable) and at the instant I connected the cable the charge reading jumped to 25% charged!
After 45 minutes on charge its showing as 76% charged, but you know what.....I'm not confident it actually is?
I'm going to use the phone with some more power hungry app's (Golf GPS) this morning, so will see how that goes.
my 4S and my fiancees 5 does exactly the same. my 4S will turn itself off at random percentages. it will stay off and show connect to itunes, however if i leave it for half an hour then try to turn it on, it will boot straight up to a different percentage , usually higher than the original it shut down with.
alternatively if it does shut down and i am near a power source then i can simply plug it in and it boots back up instantly. i have had to take to carrying a portable charging device so i dont get caught out (power bank ebay)
like seriously *** Apple
Like a lot of you I've owned the same 5 for just over a year and am currently updated to the newest iOS 7.0.3 -- scoured the web for ways to preserve battery life as well.
I too am having the issue of my battery telling me 15-20% charge life and then powering down of its own accord. Just happened to me recently about the moment before I stepped off for a run and it was a major buzzkill. I didn't personally notice anything funny with my "charge" until about a week or so ago coinciding more so with the iOS 7.0.3 update. (Not saying this is the culprit but I've noticed more significant problems since that update)
iOS 7 has brought much conveniences but at the same time lots of bugs & glitches that are constantly annoying my experience - iTunes Match nightmare more so than normal anyone...? May look for an alternative music cloud service if things don't shape up soon.
Get you stuff together, Apple, and stop ignoring us!
After a week where all seemed OK, although I didn't really allow the battery life to get too low due to the essential nature of the phone (for business) I tried it again on the golf course with a GPS App (settings as low to medium battery use). Went out fully charged and after 3 hours and showing 41% it switched off and refused to turn back on showing the depleted battery image and that it should be connected and charged. To be clear, the phone display isn't permanently on for 3 hours, just switched on every 10 minutes or so to get a yardage and update a score. Worked flawlessly for months until the last month or so (and on the iPhone 4 before, previously finishing a 4 hour round with always over 25% battery life left).
Got back to my car an hour later, commected it to the USB socket and after the Apple icon appeared for a little while, the phone came back to life showing 60% charge.
To repeat 1 year old Iphone 5 with latest IoS build. PITA!
To confirm, not only have I done hard resets, I've fully depleted the battery and fully charged (and repeated). No effect. I've also spent an hour with Apple support doing a full IoS restore and that hasn't helped.
My next years 2 year iphone upgrade cycle may just go elsewhere if it can't prove to be reliable.
Just to add to the list, since the iOS 7.0.3 update, my iPhone 5 also burns very quickly through the battery life, in spite of my having shut off several unnecessary sources of drain. It then often shuts down with as high as 30% battery life remaining. It does this unpredictably and then prevents me from restarting until I attach it to a power source. Not happy!
have an update on my issue.
A new phone!
Fortunately, we are close to an Apple store.
My husband ended up bringing my phone. I would say i'm a heavy user of my phone. Lot's of streaming, plugged in at work all day, plugged into a sounddock overnight.
The Genius said it was a hardware failure.
A replacement phone is given a 3mo warrenty.
BACK UP your device, as a precaution, would be the advice!
With my frequent shut down, the next step was a restore, i was able to connect to iTunes, and backed my phone up. The next day my phone would not come back to life.
the replacement phone was not able to be backed up, to the backed up version of the failed phone, due to the new software version.
I think it gave me an option to restore and maybe pick a version to back up to against, but, i gave up.
I just said it was a new phone and backed it up agains the August back up.
I lost information from August to November. (Think Memo's, new phone numbers, and photos).
