    I have some interesting observations to share with everyone.


    First, my wife and I purchased 2 iPhone 5's.  But because she had to go on a knitting retreat all she had was a factory iPhone 5 to use.  I on the other hand had an entire weekend to restore my almost 700 apps on my iPhone 5 from an iPhone 4 backup.  All went fine on the restore.


    I too began to notice the terrible battery lasting conditions.  But when my wife came home last night I asked her if she saw any battery issues.  She replied no.  Hmmm


    Some time ago I obtained a memory utility called PKiller.  It basically is a "process killer" which kills apps while keeping required software intact in memory.  To my amazement I discovered there were a ton of open applications running in the background.  AND because the iPhone 5 has doubled the amount of available RAM (1 gig) there were way more apps running than with my iPhone 4.  I used the "feature" of killing the background apps from within the PKiller app and then monitored the battery.


    Well, what do you know boys and girls......  The level of battery usage dropped dramatically.  After charging the iPhone 5 all night (with no apps running in the background) I then disconnected the charging cable at 7 am this morning and rechecked the battery level at 9am.  It had only dropped "ONE" percent.  This was a vast improvement from yesterday.


    So, I am now starting to conclude that it is the sheer number of multi-tasking applications running in the background which is causing the battery problem we are all observing.  If you were not lucky enough to get PKiller when it was in the App store when it first came out you will notice it is not there anymore.  It was itself killed by Apple soon after it was put up in the store.  Why?  because of that "feature" which kills apps.  Apple wants you to do this manually by double clicking the home button to show the list of apps running in the background and then double clicking on an app to get them to wiggle.  You can then kill all of them one at a time. 


    Granted, this is a safer way of doing it but Apple could be nicer (much nicer) if there was an option just to kill all background apps with one stroke of a slider or something.  I had something over a hundred apps running when I had the battery problem.  One thing for those who still have PKiller, even if you do kill the apps from within PKiller you would still see a fantom list still there when you double click the home button.  That also could have been the reason why Apple withdrew the PKiller app from the app store.


    SO.......... it might be useful if a number of people use the manual approach to killing those apps which access the Internet or do other background intensive activities and see if your battery life increases dramatically like mine did.  It does make sense.  But understand, by killing those apps will also stop the usefulness of those apps with no notifications etc. (which is the reason they were still running in the background)


    Sorry for the long post, but wanted to be fully clear about what my observations were and the results I was having.  I am looking forward to responses to this idea.  Also, has anyone actually found a battery management program which actually does something useful?  None I have seen really do.


    Apple, you people have done a fantastic, no ultra fantastic job with the iPhone 5 and with iOS 6.  I bow to thee (as usual) and I understand there will be things that will come up after both a hardware and system software upgrade.  But this problem has been with us for many years.  Please look into the multi-tasking / manual killing of apps situation.  With the sheer doubling of RAM on the iPhone 5 we now, more than ever, need some tools to manage our running apps.  They take more battery to run especially if they are Internet/bluetooth/gps intensive in the background.  We all truly appreciate what you do but I believe it is time to focus on this.


    Once we have some level of consensus and agreement that this helps, maybe a bunch of people would take the time to share this info with Apple.  My fingers are hurting.  (giggle)

    I have a 4S with the iOS 6 update.  My wife has a 4S without the update.  Our usages are just about the same and the battery life is just about the same.  But Apple promised better battery life for the 5 and from what I am reading here no one is getting it.  But you know anyone getting great battery life is not looking for a forum to brag only us who are not are here griping.  I hope we get something quick from Apple improving battery life for iOS 6 software.  I am not one who lives on the cutting edge and so I didn't go down and get a new 5 because of the problems associated with a new product.  I usually stay a generation behind but with Apple releasing the software for iOS 6 to the iphone 4 and 4S I got caught up in the problem or maybe not when I compare to my wife's battery life and mine.  Guess I will have to live with it.

  • Arkanok Level 1 Level 1 (0 points)

    Interesting. I hadn't thought about this being an issue at all simply because I assumed that Apple had the whole multitasking thing down, but I wonder if it's a bug in iOS 6 on some iPhone 5's that is causing them to not properly shut down?


    I'll attempt shutting down the apps manually for a few days and see what happens.

  • jharg4 Level 1 Level 1 (0 points)

    I am almost certain it is too many apps running that was draining my battery. 45 mins on the bus to work this morning listening to music and 20% of battery was gone. I had a few apps that stream data for work running and didnt think too much about it because i have used them for a couple of years on my old iphone4 without noticing this problem. I killed the processes and for the past 3 hours there has been no noticeable drop in battery level. One thing I will mention, I am not sure it's just to do with the sheer number of apps running...I wasnt running more than 5 or 6, but I think it could be also to do with how the apps run in the background. In a very un-technical way of thinking, maybe they are not quite as in the background compared with the old iOS.

    Being this is my first LTE phone. I failed to realize one thing..... My wifi is now slower than the carrier. I ran all weekend with both wifi and LTE on. My battery life was very poor. For the next few days, I will leave wifi off, and I've turned push off for my email accounts (of which I have three setup icloud, gmail, exchange). All other notifications and locations services are on. Following a weekend of at least 75 apps updating, I think things will stablize.


    Will post up my findings later this week.

  • RMGry Level 1 Level 1 (0 points)

    Have been having poor battery life with my iPhone 5 as well. Ran down to roughly 45% with texting and reading this forum in about 3 hours. Took it into apple and they said the battery was defective. Replace, and opened with **** scratches. Apple needs to get their stuff together. If you're really getting awful battery life i'd take it in.

    So they said the battery was defective eh? Aside from the scratches, how has the battery been since the swap? Same as before or did it actually improve?

  • Arkanok Level 1 Level 1 (0 points)

    I just wanted to post a quick update.


    I plugged my phone in earlier today when it was at about 52% up to 100%. While it was charging I turned "Push" for my iCloud email, made sure that LTE was OFF as well as closed up all running apps in the background.


    I left the phone sitting on the table for about 2 hours, touching it only once to take a quick photo, then took a look at the battery percentage and usage. I was surprised, it was still at 100% and the usage seemed much more realistic with 2 hours of standby and only 18 mins of usage.


    Doing some simple calculations I realized that if (based on these numbers) I left the phone down for 8 hours as I did last night, it would have only had about 1 hour and 12 minutes of usage as opposed to the 5 and a half hours from last night, which is much more acceptable.


    So I don't know if it was the closing of the apps running in the background or the fact that I turned off "Push", but it seems that at least for the time the phone is just sitting locked and idle, something worked.

    Hey Guys,


    New to this forum, I too was having the same issues. I tried all of the suggestions here, LTE Off, Screen Brightness down, Reset Network settings and nothing helped.


    I went into the location services and found that a lot of random things had access to the GPS including the Photo's application. I was not even using the App it was on in the background once I turned the location services to Photo's off and all the other random applications my battery life went up substantially.


    I know the GPS is notorious for killing battery and I am guessing that has a lot to do with it.

  • Arkanok Level 1 Level 1 (0 points)

    To an extent, yes, GPS does kill the battery, but I've had the location services active on my iPhone 4 along with iCloud Push email ect and never had a problem. That's the only reason I think it's strange that certain things like that seem to really affect the battery on the 5 when compared to the 4.

  • BatmanX Level 1 Level 1 (10 points)

    I'm definately seeing the iPhone 5 battery deplete faster than my iPhone 4s at work. I will try to be consistent and shut down any applications in the background to see if that helps. Hopefully it's just something in iOS 6 that is the cause.

  • Texas001 Level 1 Level 1 (0 points)

    Is it just me or does every new iphone release, which promises better battery management, have a battery problem.  If you search iphone 3, 3GS, 4, 4S and now 5 you will find people complaining about poor battery life. Are we expection too much?  I know many people who had a auxillary packs for their 4s.  I guess we wait for Apple to come up with something but I am disappointed with battery life on my phone and I have turned off everything I can and don't see improvement.  Hopefully someone will find the clue and I can ride his/her coattails. 

  • NimaB Level 1 Level 1 (0 points)

    To some extent I don't think it is a hardware issue. Apple has updated software in the past which has helped battery life. There could be something in the background that we are not seeing that is actively killing our batteries. Apple is most likely aware of what it is and will probably release an update soon to fix it. That is what we get for being the first waive of people that purchase new items.

    I had excellent battery life on my iPhone 4, too. I always kept wi-fi and location services on 24/7. Made sure not to keep too many apps running in background. The only thing that's changed for me since the UPS man came on Friday is LTE. So I've turned off LTE and turned on battery percentage for a day as an experiment.

  • officialbferg Level 1 Level 1 (0 points)

    I'm having some battery problems as well.


    First off, this is my first iPhone. I was pretty pumped and I really liked it. However, one of the big features that drew me in was the battery life. 8 hours of 3G/LTE browsing time was huge for me because I browse a lot on my smartphone.


    However, I feel I'm not getting that. So far today, 2 hours and 49 minutes of usage and 3 hours and 42 minutes of standby and I'm down to 64% in the battery. Getting from 100% to 99% took about half an hour of actually using my phone. Since then it's been going down pretty fast. I've been using iMessage and kept it on for about an hour and a half and probably dropped about 30%.


    I've done some steps I've read in this forum. I've backed up and restored. I've clearned the settings. I currently only have Siri and Weather tracking my location. I was hoping that this phone would be one where I wouldn't have to charge it every night, and still have enough battery to get me through some of the next day.


    I guess I could turn Siri and Location Services right off, but those were some of the reasons I bought the phone in the first place. Do my statistics seem like they're poor battery life, or good battery life? I'm not really sure as I've never had an iPhone to compare it with.
