    Ok so it seems everyone is having different experiences with how messed up their battery is.  Does anyone be know what's considered normal battery drainage for an iPhone 5?  I've had battery issues as well (probably still do) and I've done a bunch of "fixes" like turn off Bluetooth, reset all the settings, and even did a factory restore as a new iphone using iTunes.  I would lose one percent bout every 3 or 4 mins using wifi and one percent every few hrs.  I took my phone to apple an they said there was not wrong with the battery, but that still seems like unusually fast battery drainage.  I guess I still don't know how fast the battery SHOULD be draining.  With minimal use it would last for about 2 days.  Does that sound right?  Oh and I'm running iOS 6.1.2 maybe if we all say how long before we need to charge our batteries with X amount of usage we can get an idea of the most common problem and work from there.

    And I meant to say I would lose one percent every 3 to 4 mins using wifi and one percent every couple of hrs on standby

    I was told when I called Apple 8-12 hrs is considered normal battery life when it's good. It *****.  Mine is better since they took all my settings/info off the phone and put it back on but I don't use it alot. I now get 12 hrs. Pretty disappointing considering it's Apple but what to do. Duped!

    That's BS - they just messed up battery life with iOS6, and the last update has made it a lot worse for many users (6.1.2) even though it was supposed to fix a battery issue.

     

    My battery life is now barely 12 hours.

     

    My iPhone 4 with iOS 5 lasted comfortably through 1 1/2 days, there was never a question whether it would make it until the evening. The iPhone 5 has a bigger battery than the 4. And I don't have 4G here either. So this is certainly something that got screwed up.

     

    I have a pretty good idea what it is too: My usage stats are outrageous. This morning I disconnected from power. 3 hours later - I hadn't used the phone at all, really - it's at 82% and usage stats say that out of the last 3 hours, I have spent 1 1/2 using the phone. Well - that's not true. This phone is doing lots of stuff when it shouldn't that's why it's using all that battery.

     

    Check Settings->General->Usage and see if that correlates with how much you have, in fact, used the phone. I bet it's wildly off too.

     

    When I am down to 1% and check usage, it will tell me 5 hours of usage, and 7 hours of standby - that would mean that I spend nearly half the day glued to my phone. I do use it a lot but not *that* much. There isn't enough time for me in the day to actually use my phone for 5 hours - I have a job.

    If you don't use your phone at all (it stays asleep) battery life should be very good (mine's at 67% with Usage stats of 1hour and 22 minutes and standby of 20 hours, 19 minutes.)

     

    LTE drains battery the fastest, at a rate of approximately 1% per two minutes.

    @Nikolaus Heger

     

    According to the Apple specs (http://www.apple.com/iphone/specs.html), the iPhone 5 has the following battery life:

     

    • Talk time: Up to 8 hours on 3G
    • Standby time: Up to 225 hours
    • Internet use: Up to 8 hours on 3G, up to 8 hours on LTE, up to 10 hours on Wi-Fi
    • Video playback: Up to 10 hours
    • Audio playback: Up to 40 hours


    Even taking into account their disclaimer (All battery claims depend on network configuration and many other factors; actual results will vary. Battery has limited recharge cycles and may eventually need to be replaced by Apple service provider. Battery life and charge cycles vary by use and settings. See www.apple.com/batteries and www.apple.com/iphone/battery.html for more information), no one is even close to these figures.

     

    NOTE - under "USAGE", "Standby" tells you how long your phone has been unplugged; "Usage" tells you how long you have been actively using the phone.  So, if you have 5 hours of usage, and 7 hours of standby, it DOES NOT mean that you've used your phone for 12 h (5 of use and 7 of standby).  It actually means that of the 7h your phone has been unplugged, you've actively used it for 5h.  Which really makes the statistics worse and not even close to the 8h of continuous use.

     

    I dare them to show me that I can do 10h of video playback when the phone loses 20% every hour.

    You aren't noting the words "Up to."

     

    Put the phone in Airplane Mode and watch SD video stored on your phone and you should get around 9.5 hours of play given your device and battery aren't brand new and your screen brightness is set to the minimum level that keeps the video readily visible.

     

    For cell use, shut off push and Bluetooth and make sure no other apps are running and stand as close to a cell tower as practicable (the weaker the cell signal, the higher the battery draw.)

     

    Standby?  Fully charge the iPhone, enter Airplane Mode, don't start any apps and don't touch it for a week or so.

     

    "Up to" ratings are often like vehicle MPG ratings - ideals the vehicle is capable of, but that you may never see.

    @ William, yes, I know it says "up to", otherwise everyone on this forum would be entitled to a refund no questions asked and Apple would be sued for false advertising.

     

    It is clear, however, that a phone that just sitting on the desk with minimal usuage (checking emails, some texts, etc.) drops 20% battery per hour is not even remotely close to the advertised performance.

     

    I laugh when I see "up to 10 h" of LTE usage. Many of the posters here achieve, if they are lucky, half that amount.

    Unlike most of what I've read through here, my problem would really seem app related but I've been unable to id the culprit.

     

    I've had my 5 since Oct/Nov and have had very good battery life.  I manage it closely and don't use raise to speak, for instance, and really watch what gets location services.  Generally, only apps that really need it and that can't be used without.  Like for weather, I don't use location, I just enter city names or zipcodes.  I use LTE all day long at work (in meetings), reasonable brightness, and have had bluetooth on in the past though not now.

     

    I consistently go all day 7a-11p without need to charge.

     

    Until Wed 2/27.  That's when I noticed it running hot and draining quickly.  This has continued through tonight (3/4) and I'm restoring now.  I keep my ios and apps updated and think that a recent app update is the source but there doesn't seem to be a way to see just what updated when (hard to believe, but point me to it, please!).  I updated to 6.1.2 a couple of weeks ago without issue, so that's not it.

     

    I do recall a similar issue once before but was after adding a mapping/navigation app and that was easy to sleuth.  This time around I'm at a loss without remembering just what I updated last week.  Heard about problems with Evernote and since they just reset all of our passwords, thought that could be it (trying to access in vain), but deleting it made no difference.

     

    Anyway, figured I'd throw this out here to see if anyone has experienced this variety of drain issue: stable under 6.1.2 until all of the sudden...

    I'm quite sure it's the update. I think that somehow there is a conflict between the update and unknown app(s). Once you run it, the battery starts to drain off quickly and gets to overheat. even that app(s) is not running(even on backround). I had the same problem a couple of month ago and posted here. Apple store denied that there was a hardware problem and refused to replace my iphone5 after turned off several functions, however, the battery still cannot last more than 5-6 hours without being used. After got my new iphone5, the problem was gone. Battery drops 10% during the night (8 hours) with no apps running backround, bluetooth turned off, location service turned off, mail accounts fetch data every 15 mins. haven't try it but i do believe that, if i turn on those functions and not kill the backround apps, the battery would drop an extra 5% at most. I did not update to the current 6.1.2 because my new iphone5 is working well.

     

    So my advice is don't update your iphone unless it's necessary because the problem comes after you update your iphone and you don't know what exactly cause the problem. If you have the problem already (obviously we all do), try to have it replaced and forget trying to fixed it because you are not an apple engineer(I'm not, i tried and failed).

    Yes it's due to apps. The problem is iOS 6 which allows apps to run for up to 10 minutes when in the background.

     

    I think on my phone the culprit - or one of the culprits - was Kik messenger; there were lots of crash logs for Kik in my diagnostics logs. And then maybe my usage pattern is not good - I usually open three of four apps very quickly, then shut off the phone. Only, apparently, these 3 or 4 app can then run for up to 10 minutes longer.

     

    Apple has once put very firm restrictions on background processing and it seems that with iOS 6 they have gotten more lax. It should't be up to one badly written app to drain my battery; the system should monitor this and shut those ill-behaved apps off. Like it did in iOS 5 and 4.

    My crash report. If the problem repeats and there is no update soon to repair problems I return my IPhone 5. I am tired with the continuous problems and today the total battery drain that made useless my alarm clock has been the last straw.

    Herez the fix if u follow please:

    1. Disable notifications for app which u dont use

    2. Give ur battery a full cycle charge 2wice a month and disable location services for some apps

    3. And most important "restart your iphone once a day before or after full charge"

     

     

     

    Result before: only 4 hours battery

    Results now: almost 9 hours wifi fair usage includes most needs...

    And 80% on 3g n LTE with 2 hours usage of whatsapp constant n facebook n viber skype etc i bet same as Apple try to understand ur iphone

     

    Last but not the least enjoy ur iphone 5 experience u have to figure out now apple cant do it for u ( m not a representative of apple) ok take care

    I'm not on LTE, but I had this issue suddenly start this morning.

     

    I tried a lot of the suggestions to no avail. My phone was losing 1% every 10 minutes or so while I was just watching it at the home screen.

     

    I rebooted once and reset network settings, and noticed the play icon near the battery as though music was playing.

     

    Music wasn't playing - I hadn't touched that app or double-tapped or anything that would trigger it.

     

    I opened music and it was playing without sound. The phone wasn't on silent.

     

    I paused it and killed the music player app. I thought it got better.

     

    But right now I'm sitting in the airport watching it go down again.

     

    Friend said his wife's phone was acting strange, and she just let it drain to zero then plugged it in. I'm trying that - and then the Apple store. It hasn't been my week with devices...
