Hi, i have a backup iphone 3GS phone that i just upgraded to IOS6. today i found it have issues with the battery, the battery get hot even the phone is not in use at all, and the battery will run flat in about 2 hours when it was fully charged.

    My 3GS is also draining much faster than usual, but nothing as bad as yours.


    I get about half the time I did before and have now swithed of automatic fetch/push mail. If that doesnt help, I will switch off 3G, and Wifi etc., to see what is causing the main drain. But if I can't sort this in a couple of days I will restore to 5.1.1 (which I might do anyway because I need the bus times on my Google maps.)

    I also have same problem.

    Battery goes empty very quickly. When I try to switch off 3G in order to deal with the problem, phone either freez or restart.

    It's really big headache.

    Dude! You said you can downgrade the iOS 6 to 5.1.1?! Teach me how to do it! I hate the battery life. It drains so fast man. Me using 3Gs also. Can you teach me how to downgrade it?

    Hi Azreen


    Well, before you go as drastic as all that, it seems my battery life problem is sorted.


    I switched off the following:

    - Automatic push/fetch mail - set it to manual only

    - Location services

    These are now hidden under Privacy settings. If you go to the very bottom of the Location settings screen you will see System Services. Most of these can usually be off. Only if you need map directions a lot and changes cities etc, you may need some. In fact, rather switch location setting off alltogether and when you need it, e.g. in maps, it will tell you to switch them on.

    Rebooted the phone and all seems well.


    Back to your original question.


    I've never actually downgraded, but assume the process will be as follows:


    If you made a backup of the phone earlier, I guess you could just try the Restore option first in iTunes.




    - Download the 5.1.1 IPSW firmware file for your phone. (about 700MB)

    Look for a trusted source on the internet. e.g. do a Google for "ipsw download 3gs 5.1.1"

    Make sure you know where on your hard drive the file is stored

    - Plug your phone into your computer with the USB cable

    - In iTunes, select your phone one the left side of the screen

    - On the rigth side of the iTunes screen look for buttons like Upgrade / Restore

    - On my Mac computer I have to hold the 'options' key when selecting Upgrade which then lets me select the IPSW file I downloaded earlier. Unless I hold in the 'options' key, it will try to download iOS6 again, so be careful.

    Not sure if this may wipe your contacts etc., so to be safe sync all of that to iCloud first.

    Same problem with my iPhone 3GS 16G on iOS 6 after update.

    2 - 3 hours it's flat & thats from a full 100% charged phone with no use.

    Never had a problem with my phone ever until the new iOS 6 install.

    Same issue after updating my iphone 3gs to ios 6.IOS 6 battery consumption is vey high in 3gs.I never face this battey issue with my phone issue starts with updating with IOS 6.

  • Kaka Dongguan Level 3 (805 points)

    As I heard, iPhone 3/3G/3GS does not well support IOS 5 software. So that, for the IOS 6 subject, in my oppinion iPhone 3 generations are not prepared to support it. That's the reason Apple creates wen devices, otherwise, how Apple can make money?  ....

    They shouldn't treat customers like this.  They used to be loyal.  Now they're evil and peeing people off!!   I'm really put off now.  Bought a new battery and my phone still runs flat IN AIRPLANE MODE in about 3 hours.  What an absolute joke!  My TWENTY FOUR MONTH contract's not up yet and i was planning on upgrading to the 5 but they can stuff it now.  It's not my fault my provider lock me into a deal before the phone is considered obsolete. 


    Thanks Apple, I've finally seen your true colours and many others have too.

    I was having the same issue, and fixed it with this advice I found on another thread:

    These were the instructions. Although it refers to ios6 Beta, it applies to the release version.


    If you went ahead and installed iOS 6 beta and determined the buggy nature of the first developer release isn’t for you, it’s time to downgrade. Most developers should know how to do this already, but if not this process is easy and you’ll be back to running iOS 5.1.1 in no time at all.

    Downgrading is identical on an iPhone, iPad, or iPod touch.

    1. Turn the device off, connect it to the computer via USB, and launch iTunes
    2. Place the iOS device into DFU mode: with the device off, hold down the Power and Home buttons together for 10 seconds then release the power button, continue holding Home button until iTunes notifies you of a device in recovery mode being detected. The devices screen should stay black as if turned off.
    3. Restore within iTunes through either method a or b:
      • a: Restore from the iOS 5.1.1 backup you made prior to installing iOS 6 beta
      • b: Restore to iOS 5.1.1 IPSW by Option-Clicking the “Restore” button, and then restore from iCloud backup when finished
    4. Let iTunes restore back to iOS 5.1.1, the device will reboot when finished

    Let me know if you have issues.

    I'm having the exact same issue with the battery running very hot and the battery draining in 2 hours or less with location services turned off!!  Apple needs to either rectify this with a patc or allow customers a discount on an upgraded phone.  The phone is pretty much useless unless it's connected to a wall outlet or laptop via the USB port. After draining it takes about 20+ minutes before it turns back on.  I'm disgusted!!!

    Same problem - I took mine to the apple store. They offered me a G4 for $149.00. I bought an android for $100.00. I think this is the only time I've heard of phones going completely dead after an apple update.

  • m4xwl Level 1 (0 points)

    Same issue here with my wife's 3GS. Fine until ios6, then phone is dead as a dodo every morning.


    Traced problem to wifi. Now the wifi gets switched off and in the morning it's fine.


    People seem to have different solutions. I tried all of these, like email push, location services etc etc, none of which helped.


    To test the solution, left the wifi on overnight again, result dead phone. So for us this is absolutely the problem.


    Seems that no one from Apple reads about these problems their customers have, or maybe they don't care.


    Ridiculous state of affairs.


    Will maybe try the downgrade (I would actually call it an upgrade!!) back to 5.1.1. What a joke.

  • kumaravel Level 1 (0 points)

    I too faced this issue...I fixed it.


    Do a clean reset, and reinstall the APPs, problem solved

    Go to setting > Reset > Erase all content and settings...

    before this take a backup.


    After erasing , restart iPhone and restore from the backup....and reinstall apps. Earlier i used to get the battery backup upto 3 hrs, now i get more than 6 hrs and standby more than a day.
