Is the 20% battery death on iPhone 5 fixed in 7.1?

I think that people who weren't experiencing battery issues on iOS 6, it's due to the fact that it's an older UI. All new operating systems will come with more animations, features, and this will cause more RAM to be in use. The more RAM that's in use, the heavier the load on the battery. Each sequential release of the OS will use massively different degrees of RAM, thus widely varying results from one person to the next.

I think the iPhone 5 had issues with the battery and this is affecting each phone differently. Just my view on it.

Battery life is affected by the wattage components need. (CPU etc.) The RAM's power need is negligible, and therefore is most likely not the culprit.

Also, iOS has a very unusual and efficient memory management process. It doesn't page out, instead it closes background apps. So the RAM is always nearly full anyway, regardless of the OS - so each new OS upgrade changes what uses the RAM, not how much is used. iOS 7 doesn't use any more RAM than before in day to day use.

They could have just silently fixed the issue... and the problem exists on 4S as well. I could be wrong, but I think the issue lies in the actual service that monitors and calculates the battery life, based on my own experiences.

I'm with you. Maybe the majority of the people who don't notice this bug have their battery percentage turned off so they never notice it. It is widespread but probably even more widespread than we think. It's gotta be a bug.

Bold statement, as many here have done exactly as you've said, and still have the issue. Never had any battery issues on previous versions of iOS.

I've even gone so far as to set up as new phone, and re-enter every one of my contacts, changed all the settings, etc, in an attempt to have the cleanest possible OS. Still dies at a random number between 5% and 25% for me.

Funny thing is, even when it restarts when I plug it in, it still shows that same number again. It will also stall and drop by ~12% at once often enough.

Basically it's completely unreliable once I'm under 30%. I hope 7.1 fixes it. I'd go back to 6 if I could while waiting for these bugs to be addressed.

I think your battery decided to go south as you updated to iOS 7. If iOS 7 was indeed the reason for your battery woes then people like myself could not run it as low as 6% before charging it again.

I'd have to suggest taking it to the Apple store to be looked at. if iOS 7 was indeed to blame than all iPhone 5S' would be suffering the same fate and they are not.

There are plenty of iOS 7 issues that affect some but not all. The fact that the 5S has a different battery than 4S could play in.

Hardware failures don't happen simultaneously with software updates very often. It's a service that runs in iOS and the new one doesn't seem to work reliably, as it did before. My actual battery life doesn't seem to be terrible (after restoring as new phone), just the percentage sometimes stalls, jumps several percentage at once.

I simply treat 25% or so as the low limit, beyond which, the phone may or may not last.

The funny thing is, if it dies at 23%, and I plug it in immediately, it boots right back up and still says 23%... you'd think it would know better ;)

Out of curiosity have you always charged your phone using authentic apple cables and charger?
 
We'll I never had this issue with my iPhone 5.
My original iPhone 5 and my actual phone (which is a replacement and came with 6.1.4 and I made the update to ios 7) never had this issue. Both phones always shutdown at couple minutes of usage on 1%

Not sure what actual widespread defects the 5 has. As for 5C, given that the internals are practically the same as the 5 and the price points would have been the same, simply from a business perspective it wouldn't have made sense for Apple to keep it I production and essentially in competition with the 5C--that's really the main thing that's obvious about it.

I can definitely believe the rumors I've been told about iPhone 5 quality issues and the massive number of iPhone 5's that have been silently replaced by Apple in the past year.

I'm on my 4th iPhone 5, each of the first three had different hardware issues. Apple replaced them all at no cost under warranty and also threw in various accessories. I'm in no way surprised that the iPhone 5 was only around for one year.

Very strange story to tell: my iPhone 5 was working quite well on iOS 7, and I had a problem with battery indications only once (it died at 23%).
Well, I sold it less than a week ago and the new owner, setting the phone as new, now had the problem almost every day.

Indeed I have. I have a few of them.

In any case, aftermarket cables would typically only risk data transfer issues, as DC power doesn't have special requirements for cabling... unless there is a break in the line, which could happen on any brand of cable.

Plenty of people are just fine with the first iPhone 5 they got. Just like plenty of people had a bunch of issues with iPhone 4 or 4S while many others didn't. I guess all these things remain "rumors" for a reason.

You are right.

BTW, the thread started with a very interesting question: is the situation better with 7.1 ?
I saw very few answers ...
 
The battery on my launch day iPhone 5 started to die at 5% at first around april of this year. By the time I went to an apple store in June, the phone was shutting down at 15% battery. The phone was running 6.1.4.

The problem has nothing to do with iOS 7. Its the battery on the iPhone 5.

This doesn't explain why I hadn't the problem with iOS 6, like many others here ...

But what's the connection between many more people starting to experiencing it right after updating to iOS 7. Seems a bit more than just pure coincidence, and seems like it's not necessarily related to just updating in a general sense as I don't recall as many discussions about this kind of thing when iOS 6 came out, for example (unless I'm not recalling things correctly).

Maybe it has to do on how old the phone is?

My phone was 7 months old wen the problem started. I had let it die a lot of times before it started and let it go down to under 5% almost every day. Mind you, I did this to my 4 too and never had this problem and to this day it still doesn't do it.

You're right, when iOS 6 came out we didn't see this problem or this many at least, but this doesn't mean that version 6.0 didn't had it since as I stated my phone did while being in iOS 6 and if you search for it you will find more cases like this one way before iOS 7 was even introduce.

The common denominator though appears to be the iPhone 5. If you search the forum you will see that in most of the cases the phone is an iPhone 5. Yes, there are a couple of 4s and 4 but the vast majority are 5 and that's, in my opinion, is why we didn't see this problem when iOS 6 came out.

Well, my iPhone 5 was 7 months old when I installed iOS 7, and was perfect battery wise.
Just a coincidence that the day after iOS 7 installation the battery started to show strange behavior ?
 
For those tha

For those lucky folks who got a replacement phone even though yours was out of warranty, did they willingly replace the phone or did you have to make a big stink about it?

I only ask cause my ohone is out of warranty and I took the phone to the ridge hill apple store in NY and they gave me "sorry but you're warranty expired" bit. I don't want to go back and have to deal with the same thing.

What can I say to them to help me get a replacement??

My phone shut off with 50% today!!! :mad:

My iPhone 5 does the same thing - at about 20% I can shut down at any moment, and some times I can power right back up and it will show 40-50% then back to 20% a few moments later. I basically keep it on a charge after it gets to 20%.
