iOS 6.1.2 Battery Issue – SOLVED

iOS 6.1.2 Battery Issue - SolvedI upgraded my iPhone 5 to iOS 6.1.2 this week, and was disappointed to see a huge drop in battery life.

Previously, I could easily make it through the day without charging but after upgrading I was down to 3-4 hours on standby and my phone was constantly over-heating!


UPDATE: Definitely worked for me. 99% after 1.5 hrs standby. 100% after 1 hrs regular usage!

UPDATE: Added confirmed solutions for iOS 6.1.3 and iOS 6.1.4.


I had read that a bug in iOS 6.1.1 was causing problems with battery life and that it was related to having a Microsoft Exchange Email on your phone. So I thought, maybe this is a similar bug. Different things seem to be working for different people, but it looks like there’s some sort of (UPDATE: try disabling Push email. See below)

Solution 1 – Re-Install Microsoft Exchange Email

Add Account

Step 1 – Delete Exchange Email Account

Go to Settings > Mail, Contacts, Calendars and click on your Exchange email account. Make sure you have your emails backed up on the server (login to the email account on your computer) and then click Delete Account.


Step 2 – Reset Phone

Hold down both the Lock and Home buttons until the phone shuts off. Then turn it back on.


Step 3 – Set up Exchange Account

Create New Exchange Email

Return to the Mail, Contacts, Calendars page and click Add Account. Enter all your account information and voila! Your battery life should be back up again!




Didn’t work? Try it with all of your Hotmail and Gmail accounts at once.

Solution 2 – Disable Push Email Fetch New Data

A very popular solution seems to be disabling Push email. Go to Settings > Main, Contacts, Calendars > Fetch New Data. Set Push to OFF. Then click Advanced, and make sure that each email is set to Fetch instead of Push.




Still didn’t work? Try these other solutions.


Solution 3 – Router firmware

Multiple users on the Apple forums have reported seeing the WiFi and 3G/LTE icons switching back and forth every 15 seconds or so while connected to a WiFi network. This seems to be caused by out-of-date firmware for their NetGear routers, which caused the iPhone to constantly reconnect to the network. Their solution was to update or revert your router’s firmware and hope for the best. This has worked, but it only applies to the alternating icons problem.


Other Solutions

Lot’s of other options have cropped up, all related to network activity. Other people online have found these things to be solutions:

  • Quit Apps with Hanging Downloads. If you have iTunes U, iTunes Match, or the App Store running with downloads waiting in the background, they are fighting for data. To quit these apps, Double-Tap the Home Button to show the multitasking tray, Press and Hold an App Icon, and tap the red QUIT icons.
  • Update to the latest version of iOS. Apple does in fact try to fix these problems so the latest update is always worth a shot.
  • Disable Documents in the Cloud.
  • Remove the SIM card, disable all network connections, restart iPhone, insert SIM card (only seems relevant to people outside the US)
  • Remove ALL email accounts, restart iPhone, re-install ALL email accounts
  • Sign out of Facebook, restart iPhone.
  • Do a completely fresh install of iOS (Don’t forget to back up to iTunes or iCloud)
  • In iTunes, go to edit>preferences>devices and check “prevent ipods, iphones and ipads from syncing automatically”
  • Check that the SIM card is seated properly in it’s tray. If the contacts aren’t cleanly connecting to the phone, you could be wasting energy. This is especially important if you cut your own SIM card out of the old one.
  • DONT USE AN ALUMINUM CASE. This aluminum blocks the 3G signal from reaching your phone. When the phone is struggling to get service, it works much harder and runs the radio signal at a higher power level. Your case is forcing your phone to work too hard!
  • NOTE: You may need to let your battery die and then recharge before the changes take effect!!

  1. Hi! What will happen if I turned off Documents and data in iCloud? What information will I lose? Hope you can help.

    • I dont personally use documents in the cloud, but I believe that nothing should be lost as long as all of your documents have been uploaded to the cloud. They should be stored in the cloud for you to re-download, and I don’t see why they would be deleted from your phone anyways.

      Can anyone confirm this?

      • Hi! I tried solution 2 about disabling push for all e-mails and iCloud. Battery stayed the same on the first day, but after charging it overnight, my battery became normal again. Now I am enjoying 2 days of battery life, and my phone does not heat up anymore.

    • I’m sorry to hear that! please let me know if you find a solution so I can share it with other people who might be experiencing the same problem.

  2. Thank you for posting some fixes. I have a 3gs and I don’t have Exchange yet I still have the battery problem after the ios 6.1.2 upgrade: severe battery drain. I can’t go out of the house now without a charger. I wish I had never upgraded and don’t know why Apple would not say “this upgrade is only to fix Microsoft Exchange accounts”

    had already tried the reset but that worked for about 12 minutes – the phone seemed to be holding a charge and then it started to drop off fast.

    I have now turned off push, and icloud documents, which I never use at all. Will let know if it works. Thanks again.

  3. i tried all the solutions but still extremely drained.. any other option.. it is so annoying.. i have to charge my iphone every 3hours and my iphone is always hot..=(

    • same here i tried all the methods but no method is working
      if u find any help or any method plz tell me..
      thanks in advance….

      • Drain your battery to 0.

        let it go down and then continue pressing buttons until the battery goes as much as possible down. (Image on iPhone should be asking you to charge it..) Don’t. Just continue pressing until the battery is way down.

        Of course, follow the steps mentioned here and then do this and then do a full charge. Should be better after.

  4. Thanks for the help, but nothing solve my problem. I have an Ipod touch 5g, after upgrade to 6.1.2 the battery drain very fast. If I don´t find a solution nearly, i take the ipod to services and see if can change to another with the warranty.
    pd: sorry for my english.

  5. I can’t thank you enough! I’m extremely happy! I bought the verizon iphone 5 last Friday. It was drained from 100% to 60% for an hour, it’s obviously that there’s something wrong. I searched on google for an hour until I found you! now it is still 100% 2 hours and continuing… If you guys ever wondering if a jailbreak would drain your battery, It’s not true. I jailbroke my iphone 5 and tested it. it’s the same without jailbreak. i’m gonna keep my new phone! :-) You guys have a good evening!

  6. sitting here on 6.1 and wondering about upgrading. I have just done a quick survey of apple discussions and google. my interpreted consensus is that this is a complex problem with many possible causes – hence the multiple solutions above. I think I will wait for 6.1.3 as I do not wish to spend a lot of time reconfiguring, reloading and restoring.

  7. Big thanks..

    it’s a little too soon to notice any major improvements to my battery life.. but disabling push email + icloud documents seems to have sorted the issues i was having with available free memory.

    Before: 150mb – 70mb
    Now: 320mb – 250mb

  9. upgraded to 6.1.3 last night and it is holding its charge once again. fopr me it seems to have just been a problem with 6.1.2.

  10. I’m on 6.1.3 and I used the first step, so far so good, I didn’t even bother setting up my exchange account because I just use the gmail app, but yeah the battery life is waaaayyyy better now thank you so much!

  11. I remember you didn’t have to disable or turn stuff off on the iPhone. The good old days, new iPhone, you can’t use it like other smart phones. Apples firmware has crippled a lot of idevices. None of those steps worked..:(

    Very kind of you to post these steps. Works for some.

  13. …nothing has worked. the battery goes away after 3+ hours & heats up still.

    not happy with apple at all!

    my cellphone ISNT a cellphone anymore, after 3+ hours without any use, the battery is dead & its now only a paperweight.

  14. I’ve been noticing for the past couple of updates especially 6.1.2+ that my battery has been horrible. Removing exchange may be my problem because it kept bugging for a password i forgot for old contacts so lets see if this fixes the problem. I surely hope so. If not, a restore may be in order

  15. I’ve tried everything you’ve suggested for my Iphone 4 to no avail. Just need to check on the remove SIM card. Do you remove SIM card when the phone is still on or do you switch it off first. I’m assuming remove it while phone is still on as the step by step include restart Iphone.


  16. Thank you!!! Solution 1, FIXED HEATING ISSUE ON IPAD 3. I’ll keep you posted if this change could also have a positive impact on the battery.
