    I have an Iphone 3gs and the battery was draining before my eyes, and the unit even got hot in the process, even when the phone was not being used.  I completely solved my own problem.  We use Lotus Notes at work so I have Lotus Traveller on my device.  I deleted my traveller profile and re-created it and that totally solved the issue.  I had tried everything prior to this above.  I know this only helps Notes users, but it was definitely the fix for me.  We run Notes Server 8.53 for the the Traveller service.

    I also wanted to add that Lotus Traveller works as sort of an Outlook profile on the device, so if you are running mail using this outlook type profile, you will be wll served to do the same thing as I posted above.

    I just deleted my iCloud account, and immediately noticed 1) the device is not running as hot, and 2) the CPU load meter, which was hovering around 50% all the time, drops to nearly 0% ("Activity Monitor Touch 3.3", by HandyPadSoft). Obviously I have to be in the Monitor app to watch the CPU load meter, so the only thing hitting the CPU is the load meter process itself (a little bit of graphic display), and any background processes. So I guess something that iCloud does in the background (that can't be turned off, apparently, as I and others have tried all kinds of thing, like switching from push to fetch, and turning off location services) is constantly using a lot of CPU for some reason.


    Oh, and I'm running 5.0.1. C'mon Apple, I hope you're reading this!

  • David Richmond Level 2 Level 2 (225 points)

    Followup: I reinstalled iCloud, because I hadn't realized it would delete all my contacts and all incoming phone calls would only show a number. (I tried to run w/o iCloud by having the iPhone directly sync to AddressBook on the computer, but since all my addressbook contacts are converted to iCloud, still no go)

    So anyway, so far so good, cpu meter still runs low, device is cool and battery doesn't drain.

    The following does only apply to  4S users


    Hi to all,

    I've updated my 4S to iOS 5.0.1 Build 9A406


    Seems that has fixed my battery problem finally.


    I Charged it on Saturday, and it went empty on Monday afternoon.

    Some facts:
    before the update, the usage and standby time in the settings were nearly the same... I think all of u know that strange one...   8hrs usage 9hrs standby, without using it...anyway...


    after the update to build 9A406 , here some facts from monday:
    1% battery left,

    9hrs Usage

    1d13hrs Standby


    ^^ after the first battery charge.... 
    hope it keeps on improving


    Before u ask:  I did no settings change from 9A405 to 9A406... nothing... so... there had to be something in 9A405 which causes the battery life problem issue....


    Hope i could help some of u.
    Try updating to 9A406 and reply to my post if this fixes ur battery problme as well.

    Had the same problem. Battery power went down about 10% per hour. Tried to solve by taking most of the notifications and location services off, tried also to take mail push off etc. Had also issues with slow network identification and slow WiFi connection. Had also issue with signing in with SIM pin.


    Did a complete restore to factory settings (Version 5.0.1 (9A406) and returned from back up. Now power consumption is down to normal i.e. 7% in four hours.


    For me the problem is solved.

    Don't know if this will hold for everyone, but I found that my battery drain on iPhone 4 iOS 5.0.1 was MUCH less (pretty much back to pre-5.0.1) after I turned off wifi sync.  Turn it off by syncing the iPhone with iTunes, select the device in iTunes, and in the Options section on the Summary tab, turn off 'Sync with this iPhone over Wi-Fi' .

  • ddesch Level 1 Level 1 (0 points)

    I have a brand new 4s ios5 with battery life issues.


    I tried turning off icloud back up and it's looking good so far. I have been browsing facebook, twitter and emails for 10 minutes and battery % didn't move.


    Good luck!

  • ddesch Level 1 Level 1 (0 points)

    Nevermind, lost +- 10% in 1hour...

  • Lawrence Finch Level 7 Level 7 (32,785 points)

    If you were using it continuously for that 1 hour that is normal and within spec (actually slightly better than spec).


    • Talk time: Up to 8 hours on 3G, up to 14 hours on 2G (GSM)
    • Standby time: Up to 200 hours
    • Internet use: Up to 6 hours on 3G, up to 9 hours on Wi-Fi
    • Video playback: Up to 10 hours
    • Audio playback: Up to 40 hours
  • USMC112 Level 1 Level 1 (0 points)

    I herewith confirm that both the -Charger- as well as the Micro-SIM Card DO NOT WORK PROPERLY

    at all. I have a  10% loss of Charger Capacity within 1 hour and without using the I-Phone 4S not at all.

    Very very strange appears the absolutely quiet comportment of Apple, while having millions and millions

    of I-Phone in the World. Is this fair???? I DO NOT THINK SO!!!!


    When you buy an APPLE I-Phone for a heavy total of money, IT HAS TO WORK, so or so.

    While doing a Job within a Security Cell, I cannot use my I-Phone, IT DOES NOT WORK,

    its to risky to use it while calling for an Alert or so.........


    APPLE, please comment some or DO SOME, like we all stay in the rain, as we lost the best ever,

    Steve JOBS, it seems that APPLE completely forgot him. Selling - Selling - Selling, that´s it,

    WE ALL ARE NOT HAPPY! Thank You.

  • USMC112 Level 1 Level 1 (0 points)

    Please excuse my some writing errors, while being in an I-Phone 4S stressy situation! SORRY.

  • Lawrence Finch Level 7 Level 7 (32,785 points)

    There are millions and millions of iPhones that do not have the problem you are reporting. If the battery is running down when you are not using the phone then some app that you have installed is running in background, probably sending or receiving data. 10% per hour is normal if there is a data intensive app running. You need to figure out which app it is.


    BTW, when Steve Jobs first said the iPhone would not support multitasking he said it was because letting apps run in background would make people unhappy with battery life. He was clearly right, but he caved in and added background processing because everyone complained about no multitasking.

    I had a battery drain issue with my Wffe's iPhone, that I actually posted about early in this thread. Perhaps my experience will help you.  In my humble opinion, the iOS5 update was an issue, however, since our iPhone was getting a little old and battery life wasn't what it should have been, we sent in the phone to have the battery replaced. Apple, to save time, sent out a different phone. Unfortunately that replacement phone was defective and we had to send that one back.  The next one they sent was a winner.  Now this process took a month, so by the time we got the replacement phone, the latest update to iOS5 was out.  Since the replacement phone had an older OS on it, I proceeded to upgrade to the latest OS.  After the upgrade was complete, I SLOWLY went through the set up process on the handset, makeing sure that everything I could turn off was off.  I did that based on all the information I read here.  My wife only turns on a service when she wants to use it. Since then, battery life has been excellent (for a smart phone) 


    Now I personally use another phone, not because of any problems with the iPhone, but because the iPhone, like most every other smartphone on the market regardless of the operating system is a computer first, phone second. I am frequently in rural areas where I need a phone that is a phone first and has the ability to connect to more distant towers.  In my opinion, the iPhone, along with most other "smart phones" are "city slicker" phones. Often the group of people I am frequently with in those rural areas with a smart phone have to borrow mine to make a call as they do not connect as well. Now I do use a smart phone, but I also carry a back up military grade phone so all I have to do is swap the sim chip to use the phone that connects better.


    Why am I telling you all this?  I think you are expecting you iPhone to be all things to all people. when you use it that way, it uses up the battery.  You have to know that regardless of brand of smart phone, when you use the apps a lot, let things run in the background, multitask, surf and play games endlessly, then the battery will drain quickly. Battery science has not kept up with what we are asking these marvelous little computers to do and in my opinion, in terms of bettery life, no brand has an advantage.  It's all in how you use it. 


    So check your settings, check for a misbehaving app and check your useage habits. You will find the answer there.

    As soon as I unplug my phone from receiving a full 100% charge, I can watch it go down. Without even opening a single app on my phone, it went to 94% in 5 minutes. After a 3 minute call, it was down to 74%. When I tried to send a text message, it died. Total time of use +- 15 minutes. Fifteen minutes of use is nowhere near the specs. And it's clearly a software problem because when I plug the phone into the wall, it immediately goes to the apple-in-the-middle startup screen and starts charging from whenever it died, this time around 74%. It charged to 100% in regular time, and the 15 minute use cycle starts all over again.
