iOS 7 low battery iPhone shutdown

I think is both. Your battery is wearing and iOS 7 is not coupling the voltage red with the right percentage.
I don't believe this to be a battery issue at all. My battery has been fine all along for one year draining all the way to 1%. Then all of a sudden I install ios7 the next day and the battery takes a dump at 20%?
It's too close to be coincidence. Also since other users reported it. It's definitely software related. My iPhone 4 batter my with same usage has zero issues for 2 years with heavy usage so I'm not buying the battery issue theory
Could be ...
Lithium batteries start to die without prior notice, and two years of heavy usage are enough time.
I don't know, could be the iOS (but then why is working fine with most of the people ?) but if I have to bet something, will be on your faulty battery.
Does anyone know if this has been recognized as an iOS 7 problem by now? My iPhone 4S started shutting down early (always when taking pictures) practically the day I upgraded to iOS 7. Never happened before and now it has happened 3 times in about two weeks. Last time, it happened at 20%.
My guess is that the problem is not related to incorrect measurements, but that the camera app in iOS 7 has a much higher peak power drain, which simply sends the phone into a kind of panic mode where it believes that the battery is close to empty. After all, there seem to mave been some tweaks to make the camera faster, and this might result in higher power usage. Also, the transparency effect in the user interface probably eats a bit more into the battery usage as well.
That could also explain why people have already experienced this in previous versions but why it seems to be more prevalent now.

shutting down if below 30%
Same thing happened to me today with iOS7/iPhone 5. I started to notice really strange behaviors from the day I installed iOS7, but today it was obvious, I had a 30% battery, had a phone call for 1 minute, after the phone call phone was dead. I managed to switch it on and see for a moment that battery level is 23% after few seconds phone shut down and came to life only after few minutes of charging. This should be obvious software fault, it never happened with iOS6. At this moment I'm just trying to figure out how to downgrade.... It is not a reliable phone anymore.

Complete iPhone restore helped
I made a complete restore of my iPhone and since that day battery seems to work ok again, I can go down to 4% and may be a bit lower until the shutdown. Having calls and GPS on and still ok. Can recommend doing a complete restore.

Do you mean "erase all content and settings" option or "erase settings?"
Because then I would lose all my data. But it I back up the phone to iTunes before I do that and then restore from backup, wouldn't that basically put me back to where I was before the restore since it's loading up my corrupted ios7 file back on?
I read this thread, then filed a warranty case for my iphone 5, just 2 weeks before end of warranty because I had the same issue. They replaced it with a brand new one
First of all, it's not a new one but a refurbished, second thing probably you just had a replacement for a software issue rather than an hardware.
Did they perform a battery test ?
Yep.
If you suspect of a broken app, you have to erase all and reinstall all apps via iTunes.
By reinstalling from iTunes from my backup, aren't I putting the same settings and battery issues back on the phone? That's what I'm trying to figure out
Huh? I'm lost. I don't want to lose my app data, photos, and stuff so I have to restore from back up.
Me too.
So you have to live with the problem ....
Btw I don't think a clean setup of yor iPhone as new could solve the problem.
I have a mophie, but I'm not happy until I find out what's happening at my iPhone.
I've tried everything ... Nothing really worked for me.
Battery behavior on iOS 7 is somewhat wrong. I'm waiting for a software fix.
