    I have to agree with you! My phone worked great prior to 3.1.3... I would go 2 days between charges and with massive use, now... I'm lucky to make it a day with minimal use and with my MobileMe turned off.

    I pray that we have an update prior to OS4 in June or July!

    Be careful what you wish for. There were iPhone owners who had battery problems after upgrading to 3.1.2, and they prayed for an update and got it - 3.1.3. The sole listed purpose of 3.1.3 (in the release note) was to solve battery problems.
  • slvrvetteIT Level 1 (0 points)
    Well to solve the issue with the battery percentage and clearly it didn't fully solve it, not really the battery or the productivity at all. It seems to be mostly just a "change" of the percentage gauge as there seems to be no difference with battery life when compared to the 3G and neither one displaying the percentages.

    It's likely that there is corrupted metadata in your email app. Try the following, in sequence, until the problem is resolved:

    1. Reboot the phone (hold Home and Sleep until the Apple logo appears; about 10 seconds).

    2. Delete the email account(s), reboot, add them back.

    3. Reset Network Settings in the Settings app and reboot.

    4. Restore the phone in iTunes.

    5. Restore again in iTunes, and this time set up as a new phone.

    You probably won't need to go beyond 3.


    *Update: SUCCESS!!!!!!*

    I've been struggling with this for a couple of months. I had to reset my iPhone 3GS about once every 2 weeks, tinkered with various e-mail accounts, calibrated my battery, etc. All with no success.

    However, I finally found the magic combination thanks to Lawrence's post.


    1) very short battery life (battery from 100% --> 0% between 8am to 4pm with very light iPhone use).
    2) Usage statistics would indicate 3+ hours of usage when the phone had really only been used 15 or 20 minutes total.


    A) I finally found the offending e-mail account: Yahoo!
    B) I went into Settings > Mail, Contacts, Calendars > Accounts > > Account:OFF
    C) I went into Settings > General > Reset > Reset Network Settings

    *Updated phone behavior:*

    a) Battery usage very light
    b) Usage vs. Standby statistics now reflect reality

    As others have stated in this thread, there seems to be a problem either with the network behavior or certain e-mail account behaviors (or both). When you find the right combination of offending e-mail account and network settings, you'll fix your battery drain problem (in this case, I didn't even have my Yahoo! e-mail account set to push, only to fetch which is why I didn't try it sooner). I'm not even going to pretend this was as easy as I made it sound. It took a couple of months of tinkering off and on to find the right combination. For me, my MobileMe push account was not the problem.

    P.S. w00t!

    Happy to hear you found a workaround.
    I have not been as lucky. And I think another annoyance is that yes I do not doubt that if I turned enough stuff off, something would work (even though I have tried... I even walked around with a restored as new user phone with no apps and no emails connected and it still went down) my issue is that, now you do not have an email account on your phone that was previously just fine until the 3.1.3 upgrade. Having email is 95% of how and why I have this phone. I just want things the way they were a month ago. Push email, push notifications on a few other apps, and two days of solid battery life... instead I am afraid to even turn it on to check the time.
  • Lawrence Finch Level 8 (35,018 points)
    The fix that works for most people does not require leaving anything turned off. Email accounts are turned off, the phone is rebooted, then they are turned back on.

    If you have restored as a new phone, not installed any apps or added back any email accounts and you still have a battery problem your phone is broken, as in bad hardware. You need to contact Apple for a replacement.

    One last thing to try is to delete the 3.1.3 firmware file from your computer to force iTunes to download a clean copy. It's possible, although unlikely, that the file was corrupted during the download.
  • MJ Britt Level 1 (0 points)
    I'm at a loss again... Phone is draining battery fast again. I'm gonna try what Lawrence suggested and re-download the firmware.

    Right now my Smart iPhone is a dumb cell phone and the battery still won't last! My son's MetroPCS MP3 phone last 3 days between charges!!!

    Surly I could not have gotten another bad phone in my recent swap? It has got to be a software problem...

    I'll report back after the firmware reinstall. Keep your fingers crossed for me.

    I just want to share that out of the 6 iPhones I deal with, only 2 are having the battery drain issue. And they are NOT the same firmware version. Mine was on 3.2.12 when i t started having the issue yesterday. I backed it up at home, then updated to 3.2.13 and the problem continues today. As soon as I get it backed up again, I will do a restore. Hope we find a solution.
  • MJ Britt Level 1 (0 points)
    Ok. After reinstalling 3.1.3 still having battery drain. I think it is 3.1.3!
    The misses has not upgraded from 3.1.2 and is not having the issues I am.
    We have very simalar settings (mail, music, etc) and hers is working like mine used too!

    How can I downgrade to 3.1.2? I have the firmware, I just don't want to brick my phone.

  • Lawrence Finch Level 8 (35,018 points)
    If it was 3.1.3 I would have the problem also. I don't, and the vast majority of 70 million iphone owners don't. You can't downgrade without jailbreaking the phone.

    Instead go back and read the whole thread and you will find suggestions that work for most people on how to fix the problem.
  • MJ Britt Level 1 (0 points)
    I understand what you are saying Lawrence; however, after re-reading the this thread, there are a lot of people having issues with 3.1.3. I have done everything that has been suggested in this thread twice, including making my iPhone a dumb cell phone (turned off all "smart" features and did not use the thing for anything) and still can not make it more then 6 to 8 hours on a full charge.

    Just this morning, the phone has been off the charger (from a full charge overnight) 25 minutes (I haven't made a call, used e-mail or safari) sent 1 text and now the phone is reading 99%...

    Losing 1% every 25 minutes (of course I did sent 1 text) if I do not use the phone at all - it might make it the rest of the day. This is acceptable?

    I'm going to try all the suggestions again, now mind you, I have swapped out 1 phone already at the Apple Store. I doubt that they will do that again... But I find it hard to believe that I could get two bad phones a year apart, and then only after installing 3.1.3

    My old phone worked brilliantly prior to 3.1.3, that was the downfall for me. My new phone has not worked properly since I got it and of course it has 3.1.3 and through this whole thing, my wife has 3.1.2 and has never had to stress about battery life - she can go 2 days without a charge (and actually use her "smart" phone).

    There is something in the firmware, it may not effect everyone, but it is effecting some of us. I have send feedback to Apple about this - I know that it will fall on deaf ears, but if the next update 3.1.4 o4 4.0 doesn't fix this - I might need to look at the android phones....

    Thanks for listening,

    Just looked at the phone again. 98% after 42 minutes.... We are not going to make it a day with no use....

    Let me tell you, I've been as frustrated (if not even more than you) about this 3GS iPhone battery issue.

    Mine is much better after knocking the yahoo! e-mail account off of the phone. I've tried everything (and then some) to get the battery life back. Please note that I have everything turned on (WiFi, Bluetooth, Location Services, Notifications, Push e-mail through MobileMe, etc.) all of the time. I won't compromise that. The only thing I have been willing to compromise this week is my 3rd tier e-mail account through yahoo! since my primary e-mail are my and accounts.

    So, to get to my point. What does your phone show for Usage and Standby at 42 minutes? e.g. I unplugged my 3GS from the charger at 7:34am today. It is now 9:33am. It shows Usage: 27 minutes and Standby: 1 Hour, 59 minutes. Now the most important thing here is that I've actually used the phone actively (e.g. display on and me using the phone either reading e-mails or looking at news stories) for less than 10 minutes total. So, what is the other 17 minutes of "usage"? I think it's stuff like when it goes to Fetch e-mail every 15 minutes and other background processes (e.g. even when the display is off and the phone is in my pocket).

    As an aside, this is a huge improvement from before I deleted the yahoo! e-mail account where the usage and standby numbers would have been swapped for no apparent reason and the phone would have felt warm to the touch. The phone, at least, is now cool to the touch most of the time.

    I had this issue with 3.1.2 also. Less so with 3.0.1 before that, so it very well may be that the 3.1.X OS does not manage battery draining processes very well. I'm still hoping that this is resolved in 4.X.X. I'm convinced it's software/firmware and not a hardware issue in my case as the battery drain speed fluctuates depending upon my recent troubleshooting steps. (e.g. it might drain slower for a while after a reset, but then drains quickly again 3 or 4 days later).

    I also definitely feel that whatever runaway process(es) is(are) draining the battery is somehow connected with the network (and therefore the iPhone radios, both 3G and WiFi). If I put the 3GS in Airplane mode, the battery drains much more slowly.

    Blah, blah, blah...

    I'm afraid that's meaningless; it's too small a sample size. For one, you had to wake the phone to read the 98%. Even if your figure is meaningful, you are seeing 1% drop in 21 minutes. That means you will get 2100 minutes (35 hours) out of the battery. The last time I checked a day was 24 hours, so 35 hours is much more than a day.

    Not here. This is a user forum.
