    My reply (on croatian ) to Zeljko 83 was:

     

    I switch to 3g only when we need it. 3g generally spends more battery life and is not relevant when we speak about battery life here in Croatia, particularly in areas with poor coverage (I'm in Sibenik) .. Yes, totally exhaust battery all the way to extinction several times at least 3, and then when it is turned off, charge up to 100% ..

    Ali za iphone5 maknuli su switch 3G on off i sada mozes iskljuciti samo LTE 4G a 3G ostaje standardan, iskljuciti ga mozes samo ako iskljucis internet u potpunosti a sta dobijem sa time, nula bodova, a wifi nema bas svuda da se moze koristiti osim doma i u bircevima.

    Kako god okrenes sjebali su update za peticu totalno.

    Nevjerovatno... To je glupo čak ako si i u području sa full 3g signalom...

    Lakrdija od applea

    Nerazumijem zasto namecu jedan standard, neka korisnici sami odluce sta zele koristiti za pristup internetu!

    Nikako mi se nesvida takav pristup.

    Ako se nista ne popravi kupit cu galaxys4 i iphonu reci adio

    In addition, altho I am aware of the fact that it is legitimate for the iphone to contact the email server several times per run. It is not legit for the smartphone to keep the Mail application running all time. (according to my troubleshooting via SysStats application)

    There's some confusion here. The iphone has a single processor. This means that only one program can run at a time. So if SysStats is running, by definition Mail is not running. All SysStats (or any program) can do is determine if another program is eligible to run. Being eligible does not mean the program is running; all it means is that the program is in memory and will run either when its time slice comes up, or, if it is suspended awaiting a signal, when the signal comes. You want idle programs to be in a suspended state rather than terminated, because there is a high cost in processing power and battery consumption to start a program that is not currently in memory. If mail were terminated every time it finished its job battery life would be even worse.

     

    SysStats is similar to the Task Manager in Windows or Activty Monitor on a Mac. If you launch Task Manager or Activity manager you will see 50 to 100 programs "running". Most of them are suspended. The same with SysStats, or with the Quick Launch ribbon on the iPhone.

    I don't care what anyone says this is a ios software issue and I have done everything listed in all of these threads to help but nothing helps. Even set up as new and haven't installed anything and still has problem. And Lawrence you can post all the previous ios problems but therefore once showing that it is a software issue we shouldn't have to disable anything when prior to this update everything was working fine the way it was so turning anything off is out of the question. Apple needs to fix this. They are the only ones that can.

    The battery does not get better with age. And yes, a drop after opening the phone with the slider is normal, because before you slide it you are seeing the last state of charge, and it isn't updated until you slide it.

    The only posts I have seen on the unreleased Beta is that it DOES NOT address battery drain issues.

    On my iPad 2 I improved battery life failing to use the Safari, I'm using Dolphin and autonomy greatly improved. But nothing like the autonomy of iOS 5.

    @Lawrence

     

    Someone is definitely not getting the point of the other. SysStats does act like a quick ribbon launch, like what you've mentioned above. Yes it may not be legitimate for 2 processes to run at the same time. But you see, the point is, Mail app is always running in the background. So basically if i acknowledge the legitimacy of sysstats acting as a quick launch ribbon, therefore I have two quicklaunch ribbons. The problem is, the home quicklaunch doesnt acknowledge the Mail app to be active/or running together with sysstats/or running in the background/or whatever you call it. But when you do open the sysstats quicklaunch ribbon, you'll notice mail app to be highlighted (in that case it is hence active) while seeing most of the processes that you've been talking about greyed out (which means not in use). This is happening to my iphone since the beginning. Most of the processes are just waiting to be opened/or activated while Mail does actually opens itself (considering that it doesnt have the ability to close itself). It might be the cause of my battery drain.

     

    I still cannot assure, IMHO. Other than that observation, i notice that whenever the phone's not in use, i can have a standby time of more or less 7hrs while maintaining the battery on 100%. Then whenever i use my phone, it starts draining the battery like a dripping faucet (even on light messaging, calling, music playing, etcetera) As i repeat, this has never happened to me, not with my 3g or 4a, not even with the old aged phones i have used before. This has been far the most problematic phone battery problem ever. 

     

    It's such a very frustrating problem. I had to charge the phone twice a day. Plus the fact that i am still uncapable of determining the real culprit annoys me even more.

     

    Thanks for the appreciation, time and concern Lawrence. Cheers. More power.

    THIS IS FOR AN iPHONE 5 RUNNING 6.1.2 & 6.1.3

     

    Okay, after I restored my phone countless times to New, Backup from old & whatever options I could think of, I have come to the following:

     

    • On 6.1.2 I tried the following:
      • Restored Phone to New/Backup
        • Configured Exchange Accounts
        • Turned off any erroneous Location Services & System Services ( Diagnostics & Usage, Genius for Apps, Location-Based Aids, Setting Time Zone and Traffic)
        • Turned Off Use Cellular Data for: iTunes, Passbook Updates & Reading List
        • Configured CardDAV account
        • Installed my Apps: Daylite, Freshbooks, Zendesk, Music, Spotify, Pictures
      • Restored phone to New
        • Configured Exchange
        • Deleted Exchange
        • Reset All Settings
        • Reconfigured Exchange
      • Restored phone to NEW
        • Configured IMAP accounts instead of Exchange
        • Added all my apps (See Above)
        • Turned off any erroneous Location Services & System Services ( Diagnostics & Usage, Genius for Apps, Location-Based Aids, Setting Time Zone and Traffic)
        • Turned Off Use Cellular Data for: iTunes, Passbook Updates & Reading List
      • Restored Phone to NEW
        • DIDN'T ADD ANYTHING (MAIL, CardDAV)
        • Installed Spotify
    • OUTCOME: Standby 100% literally FOREVER.  Touhing, looking and/or breathing near the phone is any way would drain the battery 1% every few minutes. (In reality, music play, few SMS texting, and calling)
    • *NOTE: When running 6.01 on 4S & 5, battery would never drain as quick when in use.

     

    • ON 6.1.3 BETA 2
      • I have access to this because I am a MAC Developer for iOS
      • I did exactly the same things as on top and really have not seen an improvemnt.  The battery will last forever if you do not touch it.  The moment I USE the phone, the battery drains by 1% every few minutes.
    • I am currently running 6.1.3 with all App mentioned above and IMAP.  I will get a full day with one charge but be in the RED (20%) by 6-7pm.  With 6.0.1, I was never in the RED before bedtime (11-12AM @ 50%)

     

    FINAL WORDS:

         I have been using iOS for a while and have been developing as well for sometime.  Apple has fixed this issue in the past and will again, I do have faith. 

     

    For me, I have seen a slight improvement with using IMAP, but nothing close to 6.0.1 performance.  Its staggering how different the battery drains from this current software.  Some of the suggestions in this forum work after charging 100% overnight, but usage always brings the phone back to the performance that people are complaining about in this thread.  I have accepted this reality and hope the the final version of 6.1.3 will address these performance issues...

    @ Macdev_Fighter You're right! This is the way my iPhone 5 with IOS 6.1.2 behaves too.

    Apple should fix this mess with IOS.
