    Just did what you said. Seemed to of worked great. Before I did this the phone would get very hot while listening to music, watching movies, ect. Battery life would not even get me through the morning.

     

    Thanks for the Help

    I had the same problem after upgrading to the iphone to 4,3,3

    The way I overcome the problem was to go to General - Restrictions - Enable Restrictions and then Disabled Restrictions and since then the battery life is back to normal.

    To follow up on my experience, I had took my new phone (#2) back to the store, where the tech performed a "DFU" reset, which is supposed to be more complete than even an iTunes new phone setup. I set up my email and nothing else (MobileMe first, exchange next) an hung around the store, in 15 minutes the battery went form 100% to 90%.

    I showed it to the tech who immediately replaced the phone with a new one (#3). I setup just the mail again and hung out for another half hour. by that time the new phone had dropped from a a 72% charge to 49%.

    I then received iPhone #4, set up email and waited. after an hour, the battery charge hadn't changed. Took it home, charged to 100% over night, with limited use (20 mins. of calls and normal email push) , the phone lasted through 2 days, and now over a week later, still holds the charge for 1-2 days with normal use...and it did it while roaming outside the US.

    Wow that's bad my mum had same sort of problem with Sony erricsson k800i got it replaced yet the battery still could hold a change yet mine from 2008 I could leave on for 5-6 days till needed changing

     

    So weird I hope you get this problem fixed I would suggest disable Push for mail

    and remove all email accounts to make sure it's a hardware problem since software can kill battery quickly

    Best of luck fixing this problem

    In my case I am sure the problem was down to my works email account (microsoft exhange server). I disabled that and the iphone4 runs at normal temperature again.

     

    Today I re-enabled it and so far its still ok (I didnt delete the mail account as described). My conclusion is the only piece of microsoft technology in my office that I reluctantly use, in this case (microsoft exchange server) is causing grief.

     

    Why on earth was I supprised at that!

    I just ran into the same issue with my phone suddenly running hot and eating up battery life.  It had been fine all the way up until yesterday.  Suddenly I found my phone super hot and battery down to 10% at 5PM - never has happened before (and with normal use all day)!  So I deleted all my email accounts (including my work Exchange email) and reinstalled them all and so far so good...  BTW I have a Verizon iPhone 4 running 4.2.8.  (latest update for my phone, at least that's what iTunes says)

    After removing all the email accounts and reinstalling them, I've not had any further issues. 

     

    Another possible suggestion:

    I also talked to my brother who had similar issues and went to the Genius bar, and the Genius said to try shutting down all multi-tasked apps.  Steps:  double click home button to bring up multitask bar.  Touch any icon and hold down for 2 seconds (like for regular home screen if you want to delete an app).  Little signs will come up on the apps, click them all and they will shut down any multitask running apps.

     

    HTH.

    1. Problem started as soon as we all upgraded to 4.3.3 ATT

    2. Genius Bar - noobs, knowing nothing about their products except simple things, or to do list like reboot your device, reset network settings or upgrade, reset via iTunes.

    3. I got new iPhone 4 2 weeks ago and no problems with 4.3.3. Suddenly we all had problem with ATT in Miami Area on July 28 Tuesday. I had no service for the whole day. I tought its my phone so i upgraded again with iTunes. And now i have the same issue - battery drained to 0 in 10 hours, usuly it holds for 3-4 days, and 2 days in full usage. I tried everything - Network reset, after upgrade i created new profile and added my contacts, notes, mail manually. No photos, few applications again downloaded manualy from my iphone. Apps on the background not taking much of your phones resurces and still they all off. Ill Reapeat myself - 10 hours battery is 0. None of what you typed none of what i tried from other websites works. Its a major bug with 4.3.3 still looking for a solution.

     

    P.S. BTW my phone released in march 2011, with new modem #. Antena still doesnt work - i have 1 or 2 reception bars if im using without bumper or case, my clients and friends complain that they can barely hear me. Apple didnt solved that problem.

    Hi, I'm not sure yet but I think this is the problem that I have with my work phone. I just updated the password in settings so I'm waiting for it to charge so I can see if that works. Keeping my fingers crossed. Thanks!

    The best fix for all iPhone problems. Get a different brand of phone. I've had no problem with my blackberry for years. My current phone is almost two years and battery still lasts a week. And emails never fail to come through.

     

    I've had more trouble with my iPhones than the features are worth!

    I have found that the battery life becomes worse over time. if you leave your phone switched on constantly.

    A quick fix is to turn your phone off then charge it up and then turn your phone back on and the draining is reduced considerable. The longer you leave it on the faster it tends to drain (after a few charges).

    I have also found that you need to leave it off for a couple of hours before switching back on.

    This worked for me as the battery was draining on just plain telehone (no mail, no apps, fresh OS install etc) in less than 12 hours. I have continuously run the phone for a couple of weeks. Tried switch off and now I get in excess of 72 hours on the battery (inlcuding a couple of calls).

    Thanks, seems to be holding a charge now as well as running cool. Deleted exchange account, rebooted iPhone and added exchange account back in. Works fine now. Amazing how hot the phone was getting....

    I have to re-itterate on my previous post. Low and behold it started to get hot once again. I origially purchased two iPhone4 at the same time (my girl friend has the other one). Her phone never even gets warm.

    Finally I contacted Apple and withing 2 days they replaced it on my door step. The new one is absolutley perfect.

    I think the issue is hardware, I spent hours and tried just about everything that forums and google suggested. It started to behave at one point and then reverted back to running hot again. At the end of the day they should not run hot.
