    Well, in my latest test - turning off wi-fi but not taking the train on that long ride from one side to the other of Tokyo, the battery life fell, but not as dramatically. Instead of falling to a usage of 2.5-3 hrs, It averaged out to about 5.2 hrs of usage time over the day. Most notably, the iPhone did not get warm, like it did while traveling on the train.

     

    Maybe there is something to the "constantly change cell antenna switching" theory that somebody had.

    Something it's not right.

     

    With the Wi-fi and Cellular Data turned off (both) and when close to a speaker, I can hear the "data transfer noise" that all speakers can capture. And it's not like the noise that we all can ear when the phone is searching for signal. It's the fast and repetitive noise exactly when data is being tranfered over Cellular data...

     

    How this is possible with both cellular and wi-fi turned off?

    Cellular data is turned off.

     

    Cellular connections to communicate with the cell tower for the purposes of letting the cell tower know your phone is available for incoming phone calls and text messages is only turned off in Airplane Mode.

    What is your signal strength?

     

    The weaker the cell signal, the more battery power needs to be used to "ping" the cell tower to keep it notified your phone is available.

    But I know the difference between the cellular data interference noise and when the phone is searching or comunication with the nearest cell tower like I said in my previous comment.

     

    Usually, the cellular data interference noise "beeps" are much more faster than the normal comunication noise, that are longer beeps and very easily to reproduce when we have incoming calls... with the phone near to a turned on speaker.

     

    Loud Long beeps - Incoming or Calling

    Medium Speed beeps - Voice Connection estabilished

    Very fast beeps - Cellular Data being Transfered

    Almost 100%, 4-5 bars constantly!

     

    3 hours battery drained...!

    Where within the general cacophony does celluar traffic checking for or sending SMS messages fall?

    Try double clicking your home button (the circle button at the bottom of the phone) and then sliding the images you see up it will close your apps but NOT DELETE THEM it halos save battery a lot

    Usually, when I receive or send an SMS the interferece sound looks the same of the voice connection estabilished.

     

    But in the cases that I ear the "very fast beeps" just like some data are being transfered, I have the cellular data turned off, wi-fi turned off, im not receiving or sending any SMS and the first thing that I try to see it's the network bars, to make sure if I have network or any drop when the phone is changing to another cellular tower with better reception.

     

    I notice this on the iPhone, on Android phones that I had in the past and in my old Symbian Phone (that has 3G, AGPS) I've never noticed any interference of data being transfered when the cellular data was turned off...

     

    Im not any expert but I can almost guarantee that the iPhone transfer some kind of data and maybe, just maybe, that's one of the causes that makes the battery drain faster even when the phone its on sleep mode.

    Alien47,

     

    I have done it twice.  The second time, I added no apps back.  It still drains like a seive.  Just how many times should I do this? 

     

    Either way, the user experince of this stinks.  I shouldn't have to delete my phone and start over all the time to fix some kind of OS or software problem.  I am not going to do this every week for the next year.  And I bought this because of the user experience in the first place....

    I know you shouldn't have to do it and it does stink so no argument there.

     

    Do you have the same problem as I had? When you turn off mobile data just using wifi does your battery use return to normal?

    Doug how did you go? Did you end up doing a reset as new phone without restoring from a backup? Did it work? Just curious, your experience may help others.

    I haven't had time to try that experiment yet. As you know in my previous experiment, I restored as a new phone, but then restored from my latest backup. But I haven't tried manually reinstalling everything.

     

    Since a few days ago I'm experiencing a strange issue where the GPS indicator is on 100% of the time. Even when I quit all my apps and even if I reset my phone. I'm sure that is contributing to current battery drainage.

     

    I was going to call AppleCare about that.

    Here's another log of my experience.

     

    - Deleted all my iCloud Backups.

    - I did a clean instalation via iTunes of the iOS7. DFU mode and a totally new installation, just in case.

    - Installed all my apps manually.

    - Battery calibration after all those steps.

     

     

    And now my iPhone battery is lasting much longer than ever but I notice that I still have some problems with the percentages of the battery. Today I get the warning that my iPhone had 10% of battery, but instead of charging it, i just put the phone in sleep mode and after a 10 minutes I got my phone and the battery is now at 23%.... so the percentage increased magically.

     

    What I can conclude after that, is that the iPhone have some kind of problem measuring the battery charge and probably it's software related. So all shutdowns that I had in the past where because of that.

    My iPhone battery has been pretty poor over the past month or so. My original iPhone 5 was fine, but the lock button was only working on the left hand side so I got it replaced in September just before the warranty ended and they gave me a replacement iPhone.

     

    Over the past month I was noticing I would be on 70% by the time I got to work in the morning. It was slightly annoying but something I could live with. Woke up this morning though and put my phone in my pocket and was sitting down and noticed that my phone was getting extremely hot, almost too hot to touch and my battery was dropping at a rate of around 5% every few minutes. The phone even warned me a few times that the phone must cool down first.

     

    I ran through a bunch of checks making sure background app refresh was turned off. Turning off iCloud and Exchange checking there weren't any apps doing anything as I have had some bad experiences with Spotify sometimes causing a memory leak somewhere. I did a hard reset, same problem. I tried reseting Setttings and Network Settings. Nothing. Even plugging the phone into the USB3 port of my Mac the battery still was draining faster than it charged.

     

    I bit the bullet and formatted the iPhone and set up as a new iPhone as to not pull anything from the iCloud backup that may have caused this. Still same problem. Battery percentage still dropping like a stone. Therefore I think it is safe to say that it is a hardware issue. I then tried to plugin to the AC charger and it just gets stuck in a continuous boot loop. I managed to get it into Recovery Mode and plugged into iTunes and Restore but I keep getting a 2001 error. Doing some research online I found that this is something to do with the USB cannot connect reliably. I tried the iPad using the same lead and USB3 port on the Mac and that synced just fine. Also tried on my work Mac, same thing.

     

    It seems to me like the restore is starting with a little charge and because the battery is draining so fast the restore just fails. My iPhone is now unuseable. The furthest I can get is the connect to iTunes image.

     

    The phone is now out of warranty so do I pay the £55 + £7.95 PP for Apple to replace the battery? Is it even the battery or is the CPU gone? I will take it to the Apple Store on Saturday but I don't want to pay for a replacement phone if I can pay £55 instead.

     

    I must say that I am very disappointed with the iPhone 5. I had the iPhone, iPhone 3G and iPhone 4. I have a iPad Mini, an old MacBook, an old iMac and a 2012 MacBook Pro and a 2008 MacBook Pro for work and rarely had any issues and when I did it was minor or fixed by an OS fix. My wife had the exact same lock button problem as well. Just hoping her phone doesn't get this issue as well.
