    I've always been happy about the battery life of my 5s, with data, bluetooth, gps and tons of apps in the background on it still lasted me a good day with moderate use. I recently updated to iOS 7.1.1 and after 1 day I saw my battery declining at a rate of 30% an hour.

    I reverted back to iOS 7.1, still the same problem. I did a full reset on my iPhone. I don't have any apps on my iPhone right now, I'm using airplane mode, have background refresh switched off, screen brightness low, and still my battery drops about 15% an hour on standby ????

    This is a really serious issue as my phone is pretty much useless to me right now, anyone knows what it could be?

    Thank you so much

    At the iPhone hacks section.
    Setup as new and don't restore from backup.
    See if that fixes it.

    I did that too, still the same problem. Could it be my battery has just gone to waste all of a sudden?

    If it's under warrant take to your apple store they should replace it. Does you device get hot at all?

    Not really hot but it tends to get a little warmer than it did when my battery still worked properly I think

    Even if it's not still under warranty, have them run a diagnostic battery check on it.

    Problem is that I bought my phone in the US but I live in Belgium, there's no Apple stores around here.

    I tested my battery with a software (iBackupBot) and my battery seems to be really healthy still:

    CycleCount: 51
    DesignCapacity: 1550
    FullChargeCapacity: 1565

    Just to see if the software was legit I tested my 2 year old iPhone 5 and I got:

    CycleCount: 402
    FullChargeCapacity: 1035

    So the problem may not be my battery but something else? My carrier did an update recently to allow 4G on iPhones and it was around that time I started having battery problems, but even with airplane mode on I still get insane battery drain, so that couldn't be it right?

    Should I just send it over to a repair center or are there other options left?

    It's definitely a software bug. No way would a battery with 1565MaH drop 30% in one hour if you weren't doing anything intensive. After 7.1.1 I've noticed my battery life has gotten worse.

    I sure wish I was still on 7.0 because I easily got 10 hours of usage.

    But I did a bunch of factory resets, battery calibrations, there is absolutely nothing left on my phone, and I still get insane drainage. I just don't have a clue of whats going on and I can't send in my phone to Apple because apparently they don't have international warranty on iPhones.

    Whenever I charge my phone lets say to 50%, it will stay on 50% for about 20-30 minutes in standby, then decline really fast. Same as when I charge to a full charge at 100%. The first % always lasts long, the other ones fly

    I had a similar problem with my iPhone 5 , 64gb, I drained fast and sometimes it would simply die and when I connect it to a PC it shows 20% INSTANTLY, so I contacted appleCare, I aint a AppleCare member, and after a few minutes they ask me to enter a website on my iphone and run a scan.
    I did that , and they determined that my Battery was faulty.
    However, they decided to replace my battery for FREE, even when my warranty was out for 140 days or so, and I live in Sweden. Not only that , they even replaced my Screen for FREE, since they determined that it was of bad quality.

    Amen to Apple.

    So I suggest you contact the AppleCare support, they have a Message Chat option, it is free ONCE even without AppleCare.

    Apple sure knows how to win hearts and minds.

    I had a chat with Apple and they said I can't have service here in Belgium because my phone was purchased in the US. They did do the diagnostic test and said there was nothing wrong with my hardware. My phone doesn't shut down at weird percentages, it goes down all the way to 0. It takes the normal amount of time to charge it too.

    Indeed , WTF.

    I would try again later, the first time I did the AppeCare chat, he also said nothing wrong with it, But the next time my phone died, after a 7km walk, i INSTANTLY entered a chat with AppleCare when I got home. And maybe I was lucky and had gotten a more kind person to help me out.

    Also to save battery life try to disable all "unneeded features" such as location services , background update etc, and if nothing works I would suggest a clean install of the OS, only do a iCloud backup restore.

    or try calling your contractor if they can help out. (if on contract)

    I hope you get the iPhone working as it should as soon as possible :)

    Do you use any coverer or directly plug the charger into the power source?
    I also had a iPhone 4 which I purchased in the US but I live in India,the power output is different in India compared to US.The battery life was normal for the first few months but suddenly the battery started to drain,the iPhone lasted only 2-3 hrs.When I took the iPhone to a service centre(not official Apple) they told that the battery was damaged due to inconsistent current.Apparently since I was using the charger which was specifically made for US in India,it damaged the battery.

    This happens often with the small revision factors x.x.1 etc. I would give it 90% chance that it will revert to usual battery consumption when they update to x.x.2.
