Is anyone still experiencing battery drain?  I updated to 6.1.2 yesterday thinking the issue would be fixed and the battery life is still horrible.  The phone is constantly warm and last for only 2 hours after a full recharge from the night before. The battery drain for my iphone 4 started when I updated to 6.1.0 and before that I never had an issue until update 6.  I’ve only had update 6 for a couple of weeks. My wife hasn’t updated her OS since 4.x and doesn’t have the issue.  Her phone could go for a couple of days. We’ve both purchased our phone at the same time. I’ve tried virtually everything from disabling services to a point where you really can’t enjoy or use the iphone the way it developed.  Someone please let me know if there’s a fix for this?!


iPhone 4, iOS 6.1.2

    This issue also applies to iPhone 4, iPhone 4s, and IPhone 5 with IOs 6.x.x.

    Yep.  6.1.2 has totally screwed my iPhone4 battery life.  Iroically it was fine on 6.1.1.  Sort it out Apple.

    Solution:

     

    This is what I did to fix it. I hope this works for most of us.

     

     

    Backup iPhone

    Settings General -> Reset -> Erase All Content and Settings -> Enter your passcode

    Now everything appeared to be out of the box wit iOS 6.1.2

    Restored from backup (not as new) including all email accounts.  Turned off the following from exchange accounts (Contacts, Calendars, Reminders). Also Changed Fetch New Data to Fetch every 30 minutes.  This has stopped the overheating and battery drain.

     

    I'm currently testing each service to see if I could isolate the problem.

    I have the same issue. Upgraded to 6.1.2 and the battery does not last more than a coupe of hours.

    I have the same issue since I updated to 6.1.2. I followed cmarquez24 instructions and i am in the process of recharging the phone it is up to 73% and the phone isnt getting hot like it was. I hope this solves the issue my battery was only lasting about an hour maybe 2 at the most after the update.

    Hello everyone,

    I have an email account that uses exchange for email and it uses the calendar.  After 6.1.2 the battery issue popped up on my phone. Here is what I did to fix the battery drain problem.  Go to "Settings", then to "Mail, contacts, calendars" and select your email account.  Turn off calendars, you will get the "this will delete all stored calendar information" message.  Say yes, dont worry, you will get it all back in a few minutes. Do a soft reset on the phone.  Power it down, let it stay off for 10 seconds.  Then power it back up again.  Go back into the settings and turn on the calendar for that account. Hopefully this solved your poblem, it did for me.

    I have exactly the same problem. No issues before iOS6.1.2, with a batery life duration around two days, and now only one day with no extensive use...

    I already reset and still the same...

    I don't know waht to do...

    Apple is not really doing a good job.

    I called Apple customer support to explain the issue. For my case the problem is with the Exchnage server connection for my work email. It seems that after 6.1.2 the communication between the server and the iPohne drains the battery. I am not sure if it is related to recurrent appointments or not. Here is what Apple support asked me to do although I am not happy about it and it seems that the issue should be looked into and whatever software bug is causing it should be fixed.

    1. Go to settings

    2. Go to Mail, Contacts and Calendars

    3. Go to Fetch New Data

    4. At the top of the screen turn the Push off

    5. At the bottom of the screen select manually

     

    What that does is it only connects to the server (Exchange) when you actually open the email application. Instead of the emails being pushed from the server to the phone as they arrive and you seeing the counter of new messages displayed next to the mail app youwill see no new messages intul you actually check and wait for about 10-15 seconds for all messages to download to the phone.

     

    So in my opinion whatever the exchange issue with recurring calendar appointments originally prompted the release of OS 6.1.2 is either not solved completely or a new issue was unknowingly introduced. I tested the fix - my battery was at 100% for 8 hours without use.Went dowon to 98% reading some emails for 15 min. Then I truned push on again for 20 min - the battery went down 12% in these 20 min. I turned push off and it laster another 24 hours without a need for rechange with relatively heavy use.

     

    Cutomer support promised to report the issue to developers for futher investigations. Let's hope there will be another OS release soon to correct it.

    This is one of the first things I did and it still makes no difference. Grrrrr!

    I'm having the same problem since updating to 6.1.2.  However, I did suffer a similar issue in an earlier version of iOS 6 - quick battery drain, but for no apparent reason, it improved suddenly.  Until this update.  Now it's back and magnified by 4X.

     

    In general, I've become increasingly dissatisfied with the stability and robustness of Apple's iOS.  I'm reaching the end of my patience.  Apps that crash when they never used to.  Flaky call reliability.  The still half-baked Maps app.  And, since I purchased my "top-of-the-line" iPhone 5, a constant struggle with pathetic battery life.  (Just a side note, Apple, but when you have to carry your charger in your pocket too, the iPhone 5 isn't the thinnest iPhone ever anymore)

     

    I wrote this in another thread about this same problem (there are several).  I'm reposting it here because I'm hoping that someone in Apple is viewing these forums:

     

    Here's my problem with all of this nonsense.  I'm a very experienced Apple user.  I have at least one, and usually more than one, of just about everything Apple makes.  I'm a Mac evangelist.  Why have I become so devoted?  Because Macs work.  Apple stuff just works.  Or it did.

     

    Now, I'm having the same issues since upgrading my iPhone 5 to OS 6.1.2 as all of these people.  I shouldn't have to do restores, restarts, hold my tongue just right, or chant magic spells to make my iPhone work reliably.  I haven't hacked my phone.  I purchase all of my apps via the Apple app store.  I do updates asap.  My phone should work.

     

    Apple needs to fix this.  When you make people, that are as crazy about Apple stuff as I am, start considering Android, you've really screwed up.  I need my phone to work when I need it.  I rely on it for my work.  I count on it for keeping me in touch with ailing family members who may need my help at any time.

     

    If Apple is no longer in the business of supplying reliable phones, then I'll soon take my business elsewhere.

    I think this worked on my iphone 5. For at least 5 minutes the battery hasn't dropped from 74% while I used Safari, took pictures and went through settings. Before I would have at least 3% decrease for a few minutes use. Hope the magic stays. Thank you again!

  • jahngj Level 1 Level 1 (0 points)

    I can't agree more with your last statement "If Apple is no longer in the business of supplying reliable phones, then I'll soon take my business elsewhere" and everything else you wrote. I've been experiencing battery drain issues for some time, but especially in the last 3 months. I've done everything by the book and have tried to remain positive in the process, but now after going through about 3 cables, bending them and in essence damaging them because I have to carry an external battery connected to my iPhone 5 24-7 in order to have it in working order, I'm not so sure I want an iPhone anymore. I've had this iPhone for less than 2 years but I've had two other generation of iPhones. I love the iPhone or at least, I did until I started experiencing battery drain issues. What good is it to have an iPhone if it doesn't even stay on or turn on? This never happened before with any of my other iPhones...I was trying to hold out for the iPhone 6, but, now, I'm not sure I want to take that chance. I took it to the Apple store today, to collect on the "free" battery replacement they are offering and now, my phone won't even respond to the cable. It is now officially dead and I am one step closer to taking my business elsewhere.
