    The battery drain issue for ios 6.1.2 even after reset all settings .......my drainig issue got fixed after the following steps

     

    1. Reset seetings-factory reset

    2. Delete all mail accounts

    3. Set automatically -off(explained below)

    4. Location services-off.

     

     

     

    The battery drain on iPhone 3gs or later is because of auto time zone under date & time in settings tab. If your location services are turned off, it would still search for time zone. Please turn off the set automatically under the settings General-Date & Time-Set Automatically-OFF

    The battery drain issue started when I updated my iphone 4 to the IOS 6.1.2.
    The battery will go from 100% to 0% in about 3 hours !!!
    I called Apple support and they told me that they are not aware of an issue affecting the battery with the latest update. They did a diagnostic test on my iphone and found that my battery is healthy. Then then recommended that I backup my iphone, restore the factory settings and recover after that. In other words, delete everything off my iphone and reinstall everything all over again. I waisted a couple of hours doing that and .....I still have the issue of the battery drain.
    I finally discovered the problem, and thus the solution!

    To solve this issue, do the following:


    Settings ---> Mail, Contacts, Calendars --->Fetch New Data ---> Advanced

     

    Now click on your hotmail account or your company email account (anything in that folder other than yahoo, gmail or aol),


    Change the setting from Push to Fetch !!!

     

    And Viola ! Problem will be solved !

     

    The problem seems to be that the mail exchange (i.e. microsoft, hotmail...etc) keeps checking and pushing emails from the exchange server every second (continiousely) and this is causing the battery to drain.When you change the setting to Fetch, then emails will start downloading every 15 min; but at least your battery will hold charge as it is supposed to do, until Apple comes up with 6.1.3 that hopefully will fix this issue.

     

    Good luck. Hope this works out for you folks hence it sure did work for me this morning and it sure feels great.


    Cheers !

    :~( it didn't work for me. I followed your directions exactly.

    That's because "For every complex problem there is a simple solution - but its wrong"

     

    There are many possible causes for increased battery drain, but they all come down to one app that is stuck in a loop. You need to find that app and kill it. Which is why you see so many different solutions posted. Each one will only work if your stuck app is the same one as the one who posted the suggestion.

    ios 6.1.2 gets only troubles

    Apple service suggested me to restore my iphone 5 to "new iphone" with only native apps, i've been told to try it for 2-3 days

    at the moment : 3hours, 24 minutes of use and 20hours, 14 minutes standby

    i'm not able to understand if the problem is solved yet, i just had a phone calls some sms, and some email cheks (no Exchange but Yahoo.)  Any suggestion about my % above? thank you all

  • lola839 Level 1 Level 1 (0 points)

    Ok, is there a trend as to which app? What apps have been found to be the culprit. I'd rather start with those if I happen to have them.

    Hey Lawrence,

     

    In this case, can you delete the email account (i.e. hotmail) of your iphone and then reconfigure it ?
    Let me know if you need directives on how to do that.

    First, I don't have any problem with battery life on 6.1.2. I also don't have a hotmail account. I have an Exchange account, an IMAP account, 3 POP accounts and an iCloud account. I also have all services on all the time, including location, BlueTooth, WiFi, 3G, Notifications for about a dozen apps, System Services, Automatic Timezone. And about 180 apps from the app store.

    I am glad you all started figuring out how to start using your device.

  • Lawrence Finch Level 7 Level 7 (30,590 points)

    I've answered that several times in this thread already, but I realize it's hard to read it all and find the meaningful and useful messages among all the noise (there ARE a lot of good suggestions if you can find them).

     

    The most common offender is email related functions, especially Exchange, iCloud, Yahoo and Hotmail accounts. You can't kill email; it's a system function that just restarts if you try to kill it. So instead go into Settings and turn off any accounts of this type (all functions - email, calendar, contacts, notes), reboot the phone (hold HOME and SLEEP at the same time until an Apple logo appears), then turn the accounts back on. Wait an hour for the accounts to resynchronize with their servers. Then check battery life. (With 6.1.1 it was known to be Exchange Calendar that had a bug; that's why 6.1.2 came out so fast.)

     

    Any app that updates in background is the next to check. Facebook is the worst offender. Others include weather, stocks (both built in and from the app store), news apps, Game Center games.

     

    Another trick that will sometimes fix it (because it terminates all processes) is to run the battery down until the phone shuts off. After it shuts off charge for 4 hours with the wall charger to recalibrate the battery gauge.

    Icloud is a build-in software and is part of Apple e-mail service.

    True, but what is the relevance to solving the issue of battery drain?

  • lola839 Level 1 Level 1 (0 points)

    I have the System Status app. In the FAQs, a question asked is what causes battery drain? Here is part of the response; maybe it will help someone.

     

    "Finally the reason might be a high CPU usage of a system process. Several people have reported issues with Facebook syncing, mail syncing, iCloud syncing etc. which may cause troubles (e.g. trying to reconnect in loop when the synchronization fails for some reason). You may try to experiment with disabling these features in iOS Settings.

     

    (In the past some apps could cause high CPU usage by sending too many notifications. This should be fixed in newer iOS versions but disabling notifications might be worth to experiment with if nothing else helps."

    If it's any comfort to you... I have exactly the same problem. Maybe 2 calls... three or so hours later, I'm in the red zone. Also, my phone gets very hot. Any thoughts on what that could mean?
