    I'm now completly stumped. After reducing the amount of work the processor is doing, no location, no push email my iPhone is now better than it ever has been. Went to bed at 75% of battery. Woke up 8 hours later and battery was 72%. Scared to make any other changes now in case battery and heat problems return.

    I think you'll all start hearing soon that unofficially it's been picked up as a 'software' issue and nothing we can do but wait for an update..


    My AppleCare rep called me just now and seems that although it's not officially on their system as an issue, he was quite certain about telling me it's a software problem.


    How long it will take is anybodies guess.

    Well after resetting my phone I have nothing good to report. Phone is showing 30 min of usage with me only having been on the phone for approx 15 min at the most. Battery is down to 82% from 100% with 6 hr 30 min stand by. I would think with min. usage the battery should be higher

    Watch out for data charges! I started out worrying about the battery drain, but traced it back to the phone sending vast amounts of cellular data WHILE ATTACHED TO WI-FI, which is far more infuriating. I've just gone over my data limit for the month. I've shut off cellular data completely and now my phone is cool and keeping its charge, so that's the cause of the battery problem in my case at least. My iPad is sending a lot of data too, but thankfully is a wi-fi only model. So if you're on a restricted data plan, watch out! Apple had better be working away furiously on a patch and not thinking that this will keep for an update in a month or two.

    After my update, I too have had an incredible decrease in battery life.  Location services or not, this phone used to go upwards of 24 hours before hitting the 20% warning.  After the IOS6 update, I'm lucky to get 5 or 6 hours before it is completely dead.  Please fix this!  My phone is starting to look like an Android!  I will send any data necessary, whatever I need to do!


    I have already let the phone go completely dead and recharged for 8+ hours, I've tried usb and wall outlet, same thing.  I've turned off location and mail push and the battery is still depleting at an amazing pace!

    I will admit when I had upgraded to iOS 5 I struggled with really bad battery life for a couple weeks. Then it just diappeared.


    I was going on a backpacking trip this last weekend, I bought a 10,000m backup battery and spent Wednesday and Thursday futzing trying to eliminate the 1% per minute drain. I decided to do a complete reset to new today. But, it seems to be behaving itself. Could be one of the many things I did. I guess I will put off the reset and see how it behaves. JD

    Same here; most days my phone is dead by 6pm but today for some reason it is still at 65% at 6.30pm and I've changed nothing!

  • enchantedloom Level 1 (0 points)

    @netlocksecurity - Try Settings : general : cellular : cellular data to OFF. That was the problem for me. My phone's sending cell data all the time, even on wi-fi. Gotta be an iOS bug.

    Chris is getting info from DataWiz... has anyone else tried it?

    To add even more weirdness to the iOS 6 battery drain *and* data usage discussion:


    I've made many of the suggested changes (both here and on Apple Discussions) to my phone's settings to try and dial down the data usage in an effort to increase battery life. That has been only marginally successful. After a day of using my 1-week-old iPhone 4S to make a few calls, send a few texts, access a few sites, it is down near 20%. And this is with cellular data turned off, only WiFi on, since I am near my monthly limit. With my old iPhone 4 and 2.5 year old battery I could go 2 *days* with this kind of use before charging.

    In an attempt to track data use and get a handle on what was happening, I installed DataWiz. I'm finding that during the night, when my phone is charging and should be doing nothing, there are huge data transfers going on. Just last night DataWiz shows that each hour my phone averaged between 9 MB and 11MB data coming in! From midnight to 8am, every hour! None of this was email, there were no new ones. This is really baffling. What could be happening? Is this why so many are going over on their data plans without trying? Is this why battery life is so bad? During the day yesterday I didn't see this kind of data use, only at night and for the last couple of nights.




  • GrahameE Level 1 (20 points)

    That is well freaky. Perhaps that is what my 4S was doing. Not any more though. But all I have done is tidied up my email accounts and switched from push to fetch every 30 minutes. My battery is now deliverring what you would expect and no hot processor causing crashes.

  • enchantedloom Level 1 (0 points)

    DataWiz says I'm transferring 5MB per hour. Nothing I've tried has reduced that yet, but I've seen people pin it on several things, from the podcast app to syncing Safari bookmarks with iCloud. And now GrahameE says email pushes were the culprit for him! Whether these are all different expressions of the same thing I don't know, but I'm very glad I turned off cellular data until there's a fix or it would have cost a fortune, not to mention melting my phone. Certainly there's something wrong with iOS if it's able to send cellular data during a perfectly solid wi-fi connection (including app updates, as far as I can tell), but that alone isn't enough to explain why it's sending/receiving so much data in the first place.

  • GrahameE Level 1 (20 points)

    Definitely the only thing I did. I just focused on reducing the amount that the processor was being asked to do. The iPhone was melting!! The processor is the only thing that gets the phone so hot when not on charge. I guess when you have email on push the phone is just polling for data all the time. Now on fetch, it checks, finds no emails and stops. 30 mins later, checks again, grabs the emails and then stops.


    I also had far too many email accounts. Some POP3, some IMAP. That probably didn't help. The difference now is unbelievable.


    enchantedloom - if your phone is transferring 5MB per hour (download or upload) what the **** is it shifting????

    I'm definately from the school of 'don't get your iPhone to do too much (or what's not necessary)' but it must be such a pain to off cellular data and just rely on WiFi. I guess you have already tried killing all the apps and seeing if it still is transferring without you asking it to.


    This is such a weird mother of a problem. What the **** is going on Apple?

  • GrahameE Level 1 (20 points)

    The blanked four letter words are the place where the devil lives. Not what you may have thought

  • enchantedloom Level 1 (0 points)

    > what the **** is it shifting????


    Beats me! I shut down all apps, etc.. Some people are suddenly draining over 1GB per day! I've shifted 70MB today and it's only lunchtime.


    The main drain on my battery was because it was sending all this stuff over cellular, even though I was on wi-fi, 3 feet from the router. Shutting off cellular data has improved it a lot but now the wifi radio is the main drain.


    I've turned off push mail, as you suggest. I only had it pushing one of my accounts anyway, but we'll see what happens. I'll report back :-)

  • GrahameE Level 1 (20 points)

    This is just weird. I feel for you. My phone is now like a completely different device. Battery drain of 2% overnight (8-9 hours). No heat or crash problems. What happens if you put yours in Aircraft Mode?
