    First of all, it does not matter if 5.1.1 did not address anything regarding the battery. It could be a bug from 5.1.1 that is causing the battery drain.

     

    Before 5.1.1, I could go through the day from 100-40% before charging it when I go to bed, and now, I have to charge at least more than 5 hours before I normally do to be able to use it for the rest of the night. I always get at least 19 hours from 100-40% on 5.1, but now, I'm barely getting 11 hours on it.

     

    No I am not making it up. I pay attention to my battery usage. Wouldn't you if you're using your phone and you keep seeing the number drop?

     

    I do the same thing every morning on my phone when I wake up. Before 5.1.1, it would always last me about 40-50 minutes to get down to 99% after a full charge. Now, I'll get about 3-6 minutes if it just doesn't want to be a good battery that day, or if I'm lucky, I'd get at least 20-28 minutes before it gets down to 99%.

     

    You have no idea how many DFU mode restore I have done. Way too many for such a short period of time since 5.1.1 came out. Restore it as brand new and restored it with a backup. Every solution you could think of. Even the reset settings then charge your battery solution that has been mentioned a few times in several of these discussions.

     

    Even one of the Apple "genius" told me to send a feedback to Apple and I'd get a response within 48 hours, and it has been more than 48 hours. So disappointed. He told me he couldn't give me a replacement, but has a "case" open up for my phone since he has notes typed into a "file" when I went in last Monday, and he told me if it is not fixed, then I could back, and hopefully get a replacement.

     

    Now I have to wait for a real reason to go back to South Coast Plaza, so I could go to the Apple store since I do not feel like driving all the way there just to go to the Apple Store.

     

    Hopefully Apple will come up with a new update to address this issue. Man, I am getting fed up with all of this battery issues on and off.

    You actually got your iphone to downgrade to 5.1 from 5.1.1? How so? Apple isn't signing 5.1 anymore though. Would I still be able to do that? Don't you need to have the 5.1 shsh blob saved and yes I know that is a jailbreak term, but mine is not jailbroken. I have tried several attempts to downgrade and no luck

    I have without a doubt noticed a signficant reduction in battery life since updating to 5.1.1.  This is not in my head, aliens have not brainwashed me, I'm not currently at gun point, its simply a fact.

     

    It is very noticable!

    How did you both upgraded to 5.1.1?

     

    I would say you should do a new RESTORE in iTunes, just try it, i came from 5.0.1 and did a clean install of the new 5.1.1 by Restoring, configuring as new iPhone and after all that, restored the backed up info onto it.

     

    Do a full battery charge after all this, leave 1h and half after it gets to 100%. Just read my post on the previous page.

  • 124. Re: iOS 5.1.1 Battery issues Fixed?
    jenniferfromsanta ana Level 1 Level 1 (0 points)

    First, I updated it OTA on the phone. The next several times, I either download 5.1.1 through iTunes or a website that it had available.

     

    If you read my post, you'd see that I did a DFU mode restore and set it up as a brand new phone, in itunes. I did it all so often within a few days, that I am fed up with it already. It gets annoying after so many restores.

     

    I have done the full battery charge, reset settings, etc, etc.

    grikster Level 1 Level 1 (0 points)

    I did what i told you and it worked, i was using 5.0.1 and now i feel like im using a new phone with improved battery life and other stability issues i had.

     

    If you can just Restore the phone as new on iTunes then config the iCloud account that you have the most important things backed up, don't restore the backup you have on iTunes, do a iCloud sync, and then do a Manual Definitions - General - HARD RESET. Then config the phone as new again, put the iCloud user and passw, then install all the apps 1 by 1 on the iPhone.

     

    I did this way i described, i didn't want the old backup to ruin the chances of having a successful update. After all over leave it charging all night. It worked for me, now on standby with only GSM signal ON, like a normal phone, 8h on standby i lose 3%/4% battery. It seems normal and good now.

    Restoring and setting the phone up as new didn't help me.

    Hi, I had my 3GS on 5.1.1 and it drained the battery in about 6 hours. Even when it was off. Luckily I had the shsh for 4.1 and restored to that. Now, after 6 hours the battery is still at 87%.

    I will keep my hands off of 5.1.1 for the 3GS. My 4 is running without problems on 5.1.1

    I think it just has to do with the processor of the 3GS, it has to do much more work than the faster 4 one.

    Hi All – I have also experienced the battery drain issue on upgrade to 5.1.1.

    Like many on the forum I have tried ALL suggestions to resolve this issue, none of them have resolved the problem that Apple owners seem to be experiencing, it’s not in our minds as some suggest. My iPhone 4 and iPhone 3GS are working a treat under 5.1.1, in fact I believe the 3GS is running better than under 4.3.x.

    However I do think I have tracked the problem down, which I will document here, but first a list of the things I’ve tried:

     

    • - Fully discharge battery to <5% and then back to 100% and leave charging for 3 hours after
    • - Turn off all notifications
    • - Turn off all location services
    • - Turn down brightness
    • - Turn off ALL iCloud services (effectively delete the account)
    • - Reconfigure email account to ‘MANUAL Fetch’ only
    • - Factory restore to fresh 5.1.1 from within iTunes and then restore from back-up

     

    The only thing that stops the battery discharging at around 5% every 8 hours is turning off Wi-Fi during standby mode. Prior to 5.1.1 the iPad would drain maybe 1% every 24 hours in standby mode with Wi-Fi on.

    Puzzled by this I did some research to understand what the iPad is doing whilst in standby mode with Wi-Fi on, so below is a trace from the iPad system log so that hopefully someone can look at this , identify the issue and hopefully fix it in a future ios 5.1.x release:

    These repeating messages appear approx every 30 seconds the wakeup packet contains the MAC addresses for my router and iPad, so one of them is misbehaving. This may be to do with how these have been implemented:

     

    http://en.wikipedia.org/wiki/Wake-on-LAN

    http://en.wikipedia.org/wiki/Sleep_Proxy_Service

     

    Either way I believe this is the source of the power drain issue whilst in standby with Wi-Fi turned on, perhaps this could be a router issue and that is why the issue not hitting everyone post 5.1.1?

     

     

    All the best.

    I used to have that issue.  Not sure what I did to fix it, though.

    This seems to be happening to me too.

    Both mine and my wife's phone started draining by about 10% per hour immediately after updating the os.

    But when away from home and not connected to the home wifi they're both absolutely fine.

    Have you been able to sort your iPad out?

    No, my next test is to test against a friends WiFi network to try and eliminate the Sagem router.

    Sorted my problem very easily.

    After days and days of resetting and reinstalling software etc. All I did was reset my wifi router and it's fine again!
