    I guess your definition of upgrade is different from mine.

    A restore without backup will always fix it? Well how come it hasn't then? You say it's a conflicting app yet the second time I did a clean install I installed zero apps. I just surfed with Safari to see if I had the same kind of drain and guess what? I did. A clean install, set up as a new phone, not using a back up and installing no apps results in the same drain. This is a three month old iPhone 5 which worked perfectly prior to installing iOS7 so please don't say it's a hardware problem or something like that. It's iOS7, pure and simple.

    Lawrence Finch, you are right on target! After trying all the suggested tips, and after noting that even with less overt power-consuming settings on in iOS7 than I had on in iOS6, it became apparent that something was amiss. The temptation is to blame iOS 7 (and there may be a problem, but...), but in fact, I think that, at least in my case, the problem is Bluetooth. Let me be clear. I kept Bluetooth on in iOS6 and it did not drain the battery unduly quickly. But when I turned Bluetooth off under iOS7, the fast battery drain stopped. So I turned Bluetooth back on, disconnected from all devices, turned Bluetooth back off, then back on and things seem to be OK now. Battery consumption back to normal.


    In short, I think the problem (at least mine) is that all Bluetooth connections need to be terminated after the iOS7 update, Bluetooth turned off & back on, and things will be fine. The Bluetooth app is getting, as you put it, "stuck".

    Sure would be nice if Apple provided a resource monitor like in Android or Windows.  Then we wouldn't have to use your suggestion and remove 40 apps or tweak 20 settings just to find one bad app.  Also, there are apps that we can't disable, like the operating system.


    I've upgraded three separate 4S devices, then later a restore install, and all free devices have much worse battery consumption.  I've disabled everything that every battery drain article written since v7 was released last weak, and battery consumption is still noticeably worse than v6.


    Apple needs to provide a good resource monitor as well as a downgrade path.  Even the evil Windows provides a way to roll back an upgrade.

    My battery was also draining quickly until I noticed that the iOS 7 upgrade turned bluetooth on.  I turned it back off and I am now back to only having to charge my phone once every other day.

    Have you seen the same issue?


    I am near a full charge. Then a very short (sometimes 20-30 minutes) time later the phone shuts down due to low power. I try and restart immediately and the dead battery / cable icon comes up. If I wait 10-20 minutes and restart aften it comes back up. This morning it came back with a 72% charge after it previously shut down.


    Any ideas?

    Without any hard data to support it, I feel like my battery consumption is marginally better with iOS 7.

    You have a different, unrelated, problem. Your battery gauge is out of calibration. Do what you are doing (wait 20 minutes, then restart), but actively force the phone to use power until it shuts off again. If it does so above 1% repeat the process. As an alternative to waiting 20 minutes you can charge it for 1 or 2 minutes. It will usually take 2-4 tries to get to 1%. Once at 1% do something that uses power (the flashlight function in iOS 7 or the app "flashlight" does a good job) until the phone shuts down and doesn't restart. Then charge for 4 hours with the wall charger.


    To prevent this happening in the future do a full cycle (100% to shutdown, then charge for 4 hours) once every month or so. This is recommended in Apple's battery tips.

    Mine feels better also. But it's quite subjective. I suspect it is the finer control over background processes, that lets you turn some off.

    I tried iOS 7 on my iphone 5 and read the Ars article indicating poor wifi battery life on the ip5, so downgraded to ios 6.1.4 while it was still available. The article is at http://arstechnica.com/apple/2013/09/ios-7-thoroughly-reviewed/6/ (go to page 6 and scroll down to the battery comments).


    Since I primarily use my iphone on wifi, I'm waiting to upgrade until I see an improved result posted by someone running on an iphone 5. So far, there's no mention of improvement to battery life in any of the ios 7 updates.


    Do you guys have an opinion about your iphone 5 on wifi battery life. Do you thing Ars was wrong, or do you agree that it's less than 8 hours on ios 7?

    My phone never had the greatest battery life but not like this.  Went to the Apple store, and worthless waste of time. I was told to 'reset' the phone. Okay, that solves the problem for awhile. As soon as I pull in Email (which I do manually because of this problem) the drain begins.


    It seems to have to do with using cellular data, ie, email. It is putting the phone into STANDBy mode when it is not.  If I check the usage, it shows USAGE and STANDBY as being exactly the same.  I have reset this phone numerous times and it is always ok until I check email. I have removed ALL apps and have turned off just about everything that might use the cellular data.  Apple should be ashamed to have not acknowledged this problem. At least let me downgrade to the old IOS!

    "This problem" has been around for almost 7 years. It is not unique to iOS 7.1. And going back will not fix it, except by chance because it essentially restores the phone. Read the other messages in the thread for what to do about it.


    USAGE and STANDBY time the same ALWAYS is an app problem and has been for every iPhone and every version of iOS. An app is stuck in a loop. It can be a built in app or an app that you downloaded. The guaranteed fix is to restore the phone and set it up as new. Less drastic fixes that usually work can include deleting or turning off your Push email accounts (MS Exchange, Yahoo, gmail, hotmail), rebooting the phone and adding the email accounts back (or turn them back on). Deleting apps is not sufficient if it is an added app; you need to reboot after deleting.

    Let me tell you what is frustrating: knowing there is something wrong and nobody being able to 'fix' it. I first went to the Genius Bar and was told, surprise surprise, to reset the phone. Don't think I have not done this a million times since then.  The diagnostics they ran showed the battery in excellent shape. I do believe it is something 'in a loop' but what it is is what's difficult to find. I believed it had to do with using the cellular data function but not so sure anymore.


    I have done everything others have suggested on boards with no luck.  This battery is lasting 4 hours, if I'm lucky.  When I reset the last time, I had NO APPS at all, including mail.  It ran on standby overnight and was still at 100% the following morning. As soon as I activated email, the drain began.


    Now, I have turned off ALL cellular data, all pushes, fetchs etc. I just reset AGAIN and it was fine for about an hour. I added back the email accounts (Sbcglobal and Yahoo) and the drain began before I even manually checked mail via wi-fi.  I just deleted those accounts and rebooted, and still the draining rapidly. This is total Bullsh*t and Apple should have someone address this as it is ALL OVER every board I have seen.


    This did not happen until immediately after the upgrade so I do not believe it is not related. SOMETHING changed. Apple knows what it is. This phone is useless to me at this rate and you can believe I will NOT purchase another apple product.

    Strange. That's what all of these people below said also about their versions. And you will note that NONE of them are 7.1. If your battery drain started when you enabled email, the MAYBE, just MAYBE, there is a problem with your email account. Or is that too radical a thought? For the record, my battery life is slightly better with 7.1. I have 7 email accounts, including an MS Exchange account, an iCloud account, 2 iMAP accounts, 2 POP accounts, and a gmail account. And I get excellent battery life.


    Everyone posting to each of the threads below was convinced it was a problem with their most recent version of iOS, as there were a lot of other people complaining of the same issue. That doesn't make it true, unless every version of iOS since 2007 has had the same bug.
